Can the cops get your online data? In short, yes. There are a variety of US federal and state laws which give law enforcement powers to obtain information that you provided to online services. But, there are steps you as a user and/or as a service provider can take to improve online privacy.

Law enforcement demanding access to your private online data goes back to the beginning of the internet. In fact, one of  EFF’s first cases, Steve Jackson Games v. Secret Service, exemplified the now all-too-familiar story where unfounded claims about illegal behavior resulted in overbroad seizures of user messages. But it’s not the ’90s anymore, the internet has become an integral part of everyone’s life. Everyone now relies on organizations big and small to steward our data, from huge service providers like Google, Meta, or your ISP, to hobbyists hosting a blog or Mastodon server. 

There is no “cloud,” just someone else's computer—and when the cops come knocking on their door, these hosts need to be willing to stand up for privacy, and know how to do so to the fullest extent under the law. These legal limits are also important for users to know, not only to mitigate risks in their security plan when choosing where to share data, but to understand whether these hosts are going to bat for them. Taking action together, service hosts and users can curb law enforcement getting more data than they’re allowed, protecting not just themselves but targeted populations, present and future.

This is distinct from law enforcement’s methods of collecting public data, such as the information now being collected on student visa applicants. Cops may use social media monitoring tools and sock puppet accounts to collect what you share publicly, or even within “private” communities. Police may also obtain the contents of communication in other ways that do not require court authorization, such as monitoring network traffic passively to catch metadata and possibly using advanced tools to partially reveal encrypted information. They can even outright buy information from online data brokers. Unfortunately there are few restrictions or oversight for these practices—something EFF is fighting to change.

Below however is a general breakdown of the legal processes used by US law enforcement for accessing private data, and what categories of private data these processes can disclose. Because this is a generalized summary, it is neither exhaustive nor should be considered legal advice. Please seek legal help if you have specific data privacy and security needs.

Types of Data that Can be Collected

The laws protecting private data online generally follow a pattern: the more sensitive the personal data is, the greater factual and legal burden police have to meet before they can obtain it. Although this is not exhaustive, here are a few categories of data you may be sharing with services, and why police might want to obtain it.

• Subscriber Data: Information you provide in order to use the service. Think about ID or payment information, IP address location, email, phone number, and other information you provided when signing up. 
  • Law enforcement can learn who controls an anonymous account, and find other service providers to gather information from.
• Non-content data, or "metadata": This is saved information about your interactions on the service; like when you used the service, for how long, and with whom. Analogous to what a postal worker can infer from a sealed letter with addressing information.
• Law enforcement can use this information to infer a social graph, login history, and other information about a suspect’s behavior.

• Stored content: This is the actual content you are sending and receiving, like your direct message history or saved drafts. This can cover any private information your service provider can access. 
• This most sensitive data is collected to reveal criminal evidence. Overly broad requests also allow for retroactive searches, information on other users, and can take information out of its original context. 
• Content in transit: This is the content of your communications as it is being communicated. This real-time access may also collect info which isn’t typically stored by a provider, like your voice during a phone call.
  • Law enforcement can compel providers to wiretap their own services for a particular user—which may also implicate the privacy of users they interact with.

Legal Processes Used to Get Your Data

When US law enforcement has identified a service that likely has this data, they have a few tools to legally compel that service to hand it over and prevent users from knowing information is being collected.

Subpoena

Subpoenas are demands from a prosecutor, law enforcement, or a grand jury which do not require approval of a judge before being sent to a service. The only restriction is this demand be relevant to an investigation. Often the only time a court reviews a subpoena is when a service or user challenges it in court.

Due to the lack of direct court oversight in most cases, subpoenas are prone to abuse and overreach. Providers should scrutinize such requests carefully with a lawyer and push back before disclosure, particularly when law enforcement tries to use subpoenas to obtain more private data, such as the contents of communications.

Court Order

This is a similar demand to subpoenas, but usually pertains to a specific statute which requires a court to authorize the demand. Under the Stored Communications Act, for example, a court can issue an order for non-content information if police provide specific facts that the information being sought is relevant to an investigation. 

Like subpoenas, providers can usually challenge court orders before disclosure and inform the user(s) of the request, subject to law enforcement obtaining a gag order (more on this below). 

Search Warrant

A warrant is a demand issued by a judge to permit police to search specific places or persons. To obtain a warrant, police must submit an affidavit (a written statement made under oath) establishing that there is a fair probability (or “probable cause”) that evidence of a crime will be found at a particular place or on a particular person. 

Typically services cannot challenge a warrant before disclosure, as these requests are already approved by a magistrate. Sometimes police request that judges also enter gag orders against the target of the warrant that prevent hosts from informing the public or the user that the warrant exists.

Super Warrant

Police seeking to intercept communications as they occur generally face the highest legal burden. Usually the affidavit needs to not only establish probable cause, but also make clear that other investigation methods are not viable (exhaustion) and that the collection avoids capturing irrelevant data (minimization). 

Some laws also require high-level approval within law enforcement, such as leadership, to approve the request. Some laws also limit the types of crimes that law enforcement may use wiretaps in while they are investigating. The laws may also require law enforcement to periodically report back to the court about the wiretap, including whether they are minimizing collection of non-relevant communications. 

Generally these demands cannot be challenged while wiretapping is occurring, and providers are prohibited from telling the targets about the wiretap. But some laws require disclosure to targets and those who were communicating with them after the wiretap has ended. 

Gag orders

Many of the legal authorities described above also permit law enforcement to simultaneously prohibit the service from telling the target of the legal process or the general public that the surveillance is occurring. These non-disclosure orders are prone to abuse and EFF has repeatedly fought them because they violate the First Amendment and prohibit public understanding about the breadth of law enforcement surveillance.

How Services Can (and Should) Protect You

This process isn't always clean-cut, and service providers must ultimately comply with lawful demands for user’s data, even when they challenge them and courts uphold the government’s demands. 

Service providers outside the US also aren’t totally in the clear, as they must often comply with US law enforcement demands. This is usually because they either have a legal presence in the US or because they can be compelled through mutual legal assistance treaties and other international legal mechanisms. 

However, services can do a lot by following a few best practices to defend user privacy, thus limiting the impact of these requests and in some cases make their service a less appealing door for the cops to knock on.

Put Cops through the Process

Paramount is the service provider's willingness to stand up for their users. Carving out exceptions or volunteering information outside of the legal framework erodes everyone's right to privacy. Even in extenuating and urgent circumstances, the responsibility is not on you to decide what to share, but on the legal process. 

Smaller hosts, like those of decentralized services, might be intimidated by these requests, but consulting legal counsel will ensure requests are challenged when necessary. Organizations like EFF can sometimes provide legal help directly or connect service providers with alternative counsel.

Challenge Bad Requests

It’s not uncommon for law enforcement to overreach or make burdensome requests. Before offering information, services can push back on an improper demand informally, and then continue to do so in court. If the demand is overly broad, violates a user's First or Fourth Amendment rights, or has other legal defects, a court may rule that it is invalid and prevent disclosure of the user’s information.

Even if a court doesn’t invalidate the legal demand entirely, pushing back informally or in court can limit how much personal information is disclosed and mitigate privacy impacts.

Provide Notice 

Unless otherwise restricted, service providers should give notice about requests and disclosures as soon as they can. This notice is vital for users to seek legal support and prepare a defense.

Be Clear With Users 

It is important for users to understand if a host is committed to pushing back on data requests to the full extent permitted by law. Privacy policies with fuzzy thresholds like "when deemed appropriate" or “when requested” make it ambiguous if a user’s right to privacy will be respected. The best practices for providers not only require clarity and a willingness to push back on law enforcement demands, but also a commitment to be transparent with the public about law enforcement’s demands. For example, with regular transparency reports breaking down the countries and states making these data requests.

Social media services should also consider clear guidelines for finding and removing sock puppet accounts operated by law enforcement on the platform, as these serve as a backdoor to government surveillance.

Minimize Data Collection 

You can't be compelled to disclose data you don’t have. If you collect lots of user data, law enforcement will eventually come demanding it. Operating a service typically requires some collection of user data, even if it’s just login information. But the problem is when information starts to be collected beyond what is strictly necessary. 

This excess collection can be seen as convenient or useful for running the service, or often as potentially valuable like behavioral tracking used for advertising. However, the more that’s collected, the more the service becomes a target for both legal demands and illegal data breaches. 

For data that enables desirable features for the user, design choices can make privacy the default and give users additional (preferably opt-in) sharing choices. 

Shorter Retention

As another minimization strategy, hosts should regularly and automatically delete information when it is no longer necessary. For example, deleting logs of user activity can limit the scope of law enforcement’s retrospective surveillance—maybe limiting a court order to the last 30 days instead of the lifetime of the account. 

Again design choices, like giving users the ability to send disappearing messages and deleting them from the server once they’re downloaded, can also further limit the impact of future data requests. Furthermore, these design choices should have privacy-preserving default

Avoid Data Sharing 

Depending on the service being hosted there may be some need to rely on another service to make everything work for users. Third-party login or ad services are common examples with some amount of tracking built in. Information shared with these third-parties should also be minimized and avoided, as they may not have a strict commitment to user privacy. Most notoriously, data brokers who sell advertisement data can provide another legal work-around for law enforcement by letting them simply buy collected data across many apps. This extends to decisions about what information is made public by default, thus accessible to many third parties, and if that is clear to users.

(True) End-to-End Encryption

Now that HTTPS is actually everywhere, most traffic between a service and a user can be easily secured—for free. This limits what onlookers can collect on users of the service, since messages between the two are in a secure “envelope.” However, this doesn’t change the fact the service is opening this envelope before passing it along to other users, or returning it to the same user. With each opened message, this is more information to defend.

Better, is end-to-end encryption (e2ee), which just means providing users with secure envelopes that even the service provider cannot open. This is how a featureful messaging app like Signal can respond to requests with only three pieces of information: the account identifier (phone number), the date of creation, and the last date of access. Many services should follow suit and limit access through encryption.

Note that while e2ee has become a popular marketing term, it is simply inaccurate for describing any encryption use designed to be broken or circumvented. Implementing “encryption backdoors” to break encryption when desired, or simply collecting information before or after the envelope is sealed on a user’s device (“client-side scanning”) is antithetical to encryption. Finally, note that e2ee does not protect against law enforcement obtaining the contents of communications should they gain access to any device used in the conversation, or if message history is stored on the server unencrypted.

Protecting Yourself and Your Community

As outlined, often the security of your personal data depends on the service providers you choose to use. But as a user you do still have some options. EFF’s Surveillance Self-Defense is a maintained resource with many detailed steps you can take. In short, you need to assess your risks, limit the services you use to those you can trust (as much as you can), improve settings, and when all else fails, accessorize with tools that prevent data sharing in the first place—like EFF’s Privacy Badger browser extension.

Remember that privacy is a team sport. It’s not enough to make these changes as an individual, it’s just as important to share and educate others, as well as fighting for better digital privacy policy on all levels of governance. Learn, get organized, and take action.

 

Evelyn Wang ’00 knows a few things about engineering solutions to hard problems. After all, she invented a way to pull water out of thin air.

Now, Wang is applying that problem-solving experience — and an enduring sense of optimism — toward the critical issue of climate change, to strengthen the American energy economy and ensure resilience for all.

Wang, a mechanical engineering professor by trade, began work this spring as MIT’s first vice president for energy and climate, overseeing the Institute’s expanding work on climate change. That means broadening the Institute’s already-wide research portfolio, scaling up existing innovations, seeking new breakthroughs, and channeling campus community input to drive work forward.

“MIT has the potential to do so much, when we know that climate, energy, and resilience are paramount to events happening around us every day,” says Wang, who is also the Ford Professor of Engineering at MIT. “There’s no better place than MIT to come up with the transformational solutions that can help shape our world.”

That also means developing partnerships with corporate allies, startups, government, communities, and other organizations. Tackling climate change, Wang says, “requires a lot of partnerships. It’s not an MIT-only endeavor. We’re going to have to collaborate with other institutions and think about where industry can help us deploy and scale so the impact can be greater.”

She adds: “The more partnerships we have, the more understanding we have of the best pathways to make progress in difficult areas.”

From MIT to ARPA-E

An MIT faculty member since 2007, Wang leads the Device Research Lab. Along with collaborators, she identifies new materials and optimizations based on heat and mass transport processes that unlock the creation of leading-edge innovations. Her development of the device that extracts water from even very dry air led Foreign Policy Magazine to name her its 2017 Global ReThinker, and she won the 2018 Eighth Prince Sultan bin Abdulaziz International Prize for Water.

Her research also extends to other areas such as energy and desalination research. In 2016, Wang and several colleagues announced a device based on nanophotonic crystals with the potential to double the amount of power produced by a given area of solar panels, which led to one of her graduate researchers on the project to co-found the startup Antora Energy. More recently, Wang and colleagues developed an aerogel that improves window insulation, now being commercialized through her former graduate students in a startup, AeroShield.

Wang also spent two years recently as director of the U.S. Department of Energy’s Advanced Research Projects Agency-Energy (ARPA-E), which supports early-stage R&D on energy generation, storage, and use.  Returning to MIT, she began her work as vice president for energy and climate in April, engaging with researchers, holding community workshops, and planning to build partnerships.

“I’ve been energized coming back to the Institute, given the talented students, the faculty, the staff. It’s invigorating to be back in this community,” Wang says. “People are passionate, excited, and mission-driven, and that’s the energy we need to make a big impact in the world.”

Wang is also working to help align the Institute’s many existing climate efforts. This includes the Climate Project at MIT, an Institute-wide presidential initiative announced in 2024, which aims to accelerate and scale up climate solutions while generating new tools and policy proposals. All told, about 300 MIT faculty conduct research related to climate issues in one form or another.

“The fact that there are so many faculty working on climate is astounding,” Wang says. “Everyone’s doing exciting work, but how can we leverage our unique strengths to create something bigger than the sum of its parts? That’s what I’m working toward. We’ve spun out so many technologies. How do we do more of that? How do we do that faster, and in a way so the world will feel the impact?”

A deep connection to campus — and strong sense of optimism

Understanding MIT is one of Wang’s strengths, given that she has spent over two decades at the Institute.

Wang earned her undergraduate degree from MIT in mechanical engineering, and her MS and PhD in mechanical engineering from Stanford University. She has held several chaired faculty positions at MIT. In 2008, Wang was named the Esther and Harold E. Edgerton Assistant Professor; in 2015, she was named the Gail E. Kendall Professor; and in 2021, she became the Ford Professor of Engineering. Wang served as head of the Department of Mechanical Engineering from 2018 through 2022.

As it happens, Wang’s parents, Kang and Edith, met as graduate students at the Institute. Her father, an electrical engineer, became a professor at the University of California at Los Angeles. Wang also met her husband at MIT, and both of her brothers graduated from the Institute.

Along with her deep institutional knowledge, administrative experience, and track record as an innovator, Wang is bringing several other things to her new role as vice president for climate: a sense of urgency about the issue, coupled with a continual sense of optimism that innovators can meet society’s needs.

“I think optimism can make a difference, and is great to have in the midst of collective challenge,” Wang says. “We’re such a mission-driven university, and people come here to solve real-world problems.”

That hopeful approach is why Wang describes the work as not only as a challenge but also a generational opportunity. “We have the chance to design the world we want,” she says, “one that’s cleaner, more sustainable and more resilient. This future is ours to shape and build together.”

Wang thinks MIT contains many examples of world-shaping progress, She cites MIT’s announcement this month of the creation of the Schmidt Laboratory for Materials in Nuclear Technologies, at the MIT Plasma Science and Fusion center, to conduct research on next-generation materials that could help enable the construction of fusion power plants. Another example Wang references is MIT research earlier this year on developing clean ammonia, a way to make the world’s most widely-produced chemical with drastically-reduced greenhouse gas emissions.

“Those solutions could be breakthroughs,” Wang says. “Those are the kinds of things that give us optimism. There’s still a lot of research to be done, but it suggests the potential of what our world can be.”

Optimism: There’s that word again.

“Optimism is the only way to go,” Wang says. “Yes, the world is challenged. But this is where MIT’s strengths — in research, innovation, and education — can bring optimism to the table.”

California lawmakers are pushing one of the most dangerous privacy rollbacks we’ve seen in years. S.B. 690, what we’re calling the Corporate Cover-Up Act, is a brazen attempt to let corporations spy on us in secret, gutting long-standing protections without a shred of accountability.

The Corporate Cover-Up Act is a massive carve-out that would gut California’s Invasion of Privacy Act (CIPA) and give Big Tech and data brokers a green light to spy on us without consent for just about any reason. If passed, S.B. 690 would let companies secretly record your clicks, calls, and behavior online—then share or sell that data with whomever they’d like, all under the banner of a “commercial business purpose.”

Simply put, The Corporate Cover-Up Act (S.B. 690) is a blatant attack on digital privacy, and is written to eviscerate long-standing privacy laws and legal safeguards Californians rely on. If passed, it would:

• Gut California’s Invasion of Privacy Act (CIPA)—a law that protects us from being secretly recorded or monitored
• Legalize corporate wiretaps, allowing companies to intercept real-time clicks, calls, and communications
• Authorize pen registers and trap-and-trace tools, which track who you talk to, when, and how—without consent
• Let companies use all of this surveillance data for “commercial business purposes”—with zero notice and no legal consequences

This isn’t a small fix. It’s a sweeping rollback of hard-won privacy protections—the kind that helped expose serious abuses by companies like Facebook, Google, and Oracle.

TAKE ACTION

You Can't Opt Out of Surveillance You Don't Know Is Happening

Proponents of The Corporate Cover-Up Act claim it’s just a “clarification” to align CIPA with the California Consumer Privacy Act (CCPA). That’s misleading. The truth is, CIPA and CCPA don’t conflict. CIPA stops secret surveillance. The CCPA governs how data is used after it’s collected, such as through the right to opt out of your data being shared.

You can't opt out of being spied on if you’re never told it’s happening in the first place. Once companies collect your data under S.B. 690, they can:

• Sell it to data brokers
• Share it with immigration enforcement or other government agencies
• Use it to against abortion seekers, LGBTQ+ people, workers, and protesters, and
• Retain it indefinitely for profiling

…with no consent; no transparency; and no recourse.

The Communities Most at Risk

This bill isn’t just a tech policy misstep. It’s a civil rights disaster. If passed, S.B. 690 will put the most vulnerable people in California directly in harm’s way:

• Immigrants, who may be tracked and targeted by ICE
• LGBTQ+ individuals, who could be outed or monitored without their knowledge
• Abortion seekers, who could have location or communications data used against them
• Protesters and workers, who rely on private conversations to organize safely

The message this bill sends is clear: corporate profits come before your privacy.

We Must Act Now

S.B. 690 isn’t just a bad tech bill—it’s a dangerous precedent. It tells every corporation: Go ahead and spy on your consumers—we’ve got your back.

Californians deserve better.

If you live in California, now is the time to call your lawmakers and demand they vote NO on the Corporate Cover-Up Act.

TAKE ACTION

Spread the word, amplify the message, and help stop this attack on privacy before it becomes law.

In the Northeastern United States, the Gulf of Maine represents one of the most biologically diverse marine ecosystems on the planet — home to whales, sharks, jellyfish, herring, plankton, and hundreds of other species. But even as this ecosystem supports rich biodiversity, it is undergoing rapid environmental change. The Gulf of Maine is warming faster than 99 percent of the world’s oceans, with consequences that are still unfolding.

A new research initiative developing at MIT Sea Grant, called LOBSTgER — short for Learning Oceanic Bioecological Systems Through Generative Representations — brings together artificial intelligence and underwater photography to document the ocean life left vulnerable to these changes and share them with the public in new visual ways. Co-led by underwater photographer and visiting artist at MIT Sea Grant Keith Ellenbogen and MIT mechanical engineering PhD student Andreas Mentzelopoulos, the project explores how generative AI can expand scientific storytelling by building on field-based photographic data.

Just as the 19th-century camera transformed our ability to document and reveal the natural world — capturing life with unprecedented detail and bringing distant or hidden environments into view — generative AI marks a new frontier in visual storytelling. Like early photography, AI opens a creative and conceptual space, challenging how we define authenticity and how we communicate scientific and artistic perspectives. 

In the LOBSTgER project, generative models are trained exclusively on a curated library of Ellenbogen’s original underwater photographs — each image crafted with artistic intent, technical precision, accurate species identification, and clear geographic context. By building a high-quality dataset grounded in real-world observations, the project ensures that the resulting imagery maintains both visual integrity and ecological relevance. In addition, LOBSTgER’s models are built using custom code developed by Mentzelopoulos to protect the process and outputs from any potential biases from external data or models. LOBSTgER’s generative AI builds upon real photography, expanding the researchers’ visual vocabulary to deepen the public’s connection to the natural world.

At its heart, LOBSTgER operates at the intersection of art, science, and technology. The project draws from the visual language of photography, the observational rigor of marine science, and the computational power of generative AI. By uniting these disciplines, the team is not only developing new ways to visualize ocean life — they are also reimagining how environmental stories can be told. This integrative approach makes LOBSTgER both a research tool and a creative experiment — one that reflects MIT’s long-standing tradition of interdisciplinary innovation.

Underwater photography in New England’s coastal waters is notoriously difficult. Limited visibility, swirling sediment, bubbles, and the unpredictable movement of marine life all pose constant challenges. For the past several years, Ellenbogen has navigated these challenges and is building a comprehensive record of the region’s biodiversity through the project, Space to Sea: Visualizing New England’s Ocean Wilderness. This large dataset of underwater images provides the foundation for training LOBSTgER’s generative AI models. The images span diverse angles, lighting conditions, and animal behaviors, resulting in a visual archive that is both artistically striking and biologically accurate.

LOBSTgER’s custom diffusion models are trained to replicate not only the biodiversity Ellenbogen documents, but also the artistic style he uses to capture it. By learning from thousands of real underwater images, the models internalize fine-grained details such as natural lighting gradients, species-specific coloration, and even the atmospheric texture created by suspended particles and refracted sunlight. The result is imagery that not only appears visually accurate, but also feels immersive and moving.

The models can both generate new, synthetic, but scientifically accurate images unconditionally (i.e., requiring no user input/guidance), and enhance real photographs conditionally (i.e., image-to-image generation). By integrating AI into the photographic workflow, Ellenbogen will be able to use these tools to recover detail in turbid water, adjust lighting to emphasize key subjects, or even simulate scenes that would be nearly impossible to capture in the field. The team also believes this approach may benefit other underwater photographers and image editors facing similar challenges. This hybrid method is designed to accelerate the curation process and enable storytellers to construct a more complete and coherent visual narrative of life beneath the surface.

In one key series, Ellenbogen captured high-resolution images of lion’s mane jellyfish, blue sharks, American lobsters, and ocean sunfish (Mola mola) while free diving in coastal waters. “Getting a high-quality dataset is not easy,” Ellenbogen says. “It requires multiple dives, missed opportunities, and unpredictable conditions. But these challenges are part of what makes underwater documentation both difficult and rewarding.”

Mentzelopoulos has developed original code to train a family of latent diffusion models for LOBSTgER grounded on Ellenbogen’s images. Developing such models requires a high level of technical expertise, and training models from scratch is a complex process demanding hundreds of hours of computation and meticulous hyperparameter tuning.

The project reflects a parallel process: field documentation through photography and model development through iterative training. Ellenbogen works in the field, capturing rare and fleeting encounters with marine animals; Mentzelopoulos works in the lab, translating those moments into machine-learning contexts that can extend and reinterpret the visual language of the ocean.

“The goal isn’t to replace photography,” Mentzelopoulos says. “It’s to build on and complement it — making the invisible visible, and helping people see environmental complexity in a way that resonates both emotionally and intellectually. Our models aim to capture not just biological realism, but the emotional charge that can drive real-world engagement and action.”

LOBSTgER points to a hybrid future that merges direct observation with technological interpretation. The team’s long-term goal is to develop a comprehensive model that can visualize a wide range of species found in the Gulf of Maine and, eventually, apply similar methods to marine ecosystems around the world.

The researchers suggest that photography and generative AI form a continuum, rather than a conflict. Photography captures what is — the texture, light, and animal behavior during actual encounters — while AI extends that vision beyond what is seen, toward what could be understood, inferred, or imagined based on scientific data and artistic vision. Together, they offer a powerful framework for communicating science through image-making.

In a region where ecosystems are changing rapidly, the act of visualizing becomes more than just documentation. It becomes a tool for awareness, engagement, and, ultimately, conservation. LOBSTgER is still in its infancy, and the team looks forward to sharing more discoveries, images, and insights as the project evolves.
