Keeping Your Phone and Data Private at the U.S. Border

Evolving Challenges to Privacy at the U.S. Border

The U.S. government has significantly enhanced its ability to collect information at border crossings, employing modern technology to monitor both people and their devices. While officials cite national security and efficiency as justifications, the scope of these practices raises privacy questions. Travelers’ phones, laptops, tablets, and other devices often contain highly sensitive information, from personal photos to professional documents. This reality makes privacy protections critically important.

Advanced Technology and Privacy Issues

In recent years, various tools have been introduced at the U.S. border that more deeply scrutinize travelers. For instance, “Hurricane Score,” an algorithm developed under the current administration, assesses risks posed by certain individuals seeking entry. Another tool, SmartLINK, uses geolocation and facial recognition to track immigrants’ movements via a mobile app. These technologies aim to enhance enforcement, but they’ve sparked concerns about overreach and potential misuse of personal data.

Privacy advocates, including over 100 civil rights organizations, have voiced opposition to these advancements, warning that surveillance tools might violate basic civil rights. These advocates emphasize that data collected for security could inadvertently lead to discrimination or other injustices.

New Risks Highlighted by Policy Missteps

Even well-intentioned policies have faced criticism for privacy risks. Enforcement-driven directives have widened vulnerability loopholes, leaving travelers more exposed than before.

Database Controversies

For example, during President Trump’s tenure, officials reportedly sought access to a database containing details about unaccompanied immigrant minors. Though the administration defended this as necessary for child welfare, critics argued it could lead to improper enforcement or breaches of sensitive data. These concerns are magnified when such data is insufficiently safeguarded.

GAO Findings on CBP’s Technology Oversight

In another case, the Government Accountability Office (GAO), which audits federal agencies, identified privacy failures within programs run by U.S. Customs and Border Protection (CBP). Their December 2024 report revealed gaps in protections for travelers’ personal data even as CBP used tools like surveillance towers and sensors. Until CBP addresses these lapses, travelers risk unnecessary exposure to breaches.

The Legal Framework: What Are Your Rights?

The U.S. legal system gives border officers significant powers, but questions about electronic devices remain unresolved. Understanding your rights under the “border search exception” can help inform how to approach device privacy.

How the Border Search Exception Works

The Fourth Amendment, which protects against unreasonable searches or seizures, contains exceptions that apply at borders. Under the “border search exception,” officers can inspect people and their belongings without a warrant or probable cause. Traditionally, this allowed searches of luggage, vehicles, and physical items. However, its application to electronic devices, which often store far more sensitive information, is legally contested.

Key Judicial Rulings That Shape Device Searches

Several court decisions over the past decade have tried to balance privacy with the government’s security interests. For example:

United States v. Cotterman (2013): This case distinguished between forensic and manual searches. Forensic searches, which involve transferring and accessing detailed data from devices, now require at least reasonable suspicion.
Riley v. California (2014): Though not specifically about borders, this Supreme Court decision emphasized that phones hold vast and sensitive personal information, requiring stricter standards for searches. It fuelled debates over applying similar protections to border crossings.
ACLU’s Legal Challenge (2017-2019): The American Civil Liberties Union (ACLU) secured a ruling in 2019 establishing the need for reasonable suspicion before conducting warrantless device searches at the border. However, it stopped short of requiring warrants, leaving travelers in a legal gray area.

Legal uncertainty continues to cloud travelers’ full rights in this situation. Without uniform rulings, practices at border checkpoints may vary considerably.

Real-World Implications of Border Device Searches

The implications of unchecked electronic device searches extend beyond individual cases. They raise ethical and logistical concerns, both for authorities and the traveling public.

Privacy Violations and Chilling Effects

Because phones and laptops act as gateways to personal lives, unjustified searches can expose deeply private information. Beyond the immediate loss of privacy, there’s a broader “chilling effect,” where individuals might avoid documenting, sharing, or storing certain information due to fear of border inspections. This could limit free expression and personal freedoms.

Technical Challenges in Accessing Encrypted Data

Devices today often utilize encryption to secure user information. Whether border agents have the authority to compel travelers to unlock these devices or provide passwords remains debated. With many users browsing or storing files in the cloud, the scope of potential violations expands even further. Guidelines on these issues remain undefined, compounding travelers’ concerns.

Practical Steps to Protect Phone and Data Privacy

Travelers can take proactive measures to shield themselves from invasive border searches and safeguard stored information.

Reduce Your On-Device Information

The best approach to protecting data is limiting what you carry across the border. Before traveling, remove any non-essential files from your devices. Many frequent travelers recommend using temporary “clean” devices, particularly for international trips. These devices store only the data you need for immediate use, minimizing privacy risks.

Enable Encryption

Encryption converts your stored information into unreadable data, which can only be unlocked with the correct password. Enabling encryption on your phone, laptop, or tablet makes it harder for unauthorized individuals to access your files.

Log Out from Important Accounts

Apps like email, cloud storage, and messaging platforms often hold vast records of sensitive information. Logging out or disabling these apps ensures that even if someone searches your device, they won’t have easy access to your online accounts. This step adds an additional layer of protection.

Document Searches and Assert Your Rights

If you’re subject to a device search, take note of what happens and ask questions. For instance, you have the right to ask how data collected from your devices will be used or stored. While officers may request passwords, they cannot compel compliance without suspicion of wrongdoing. State your concerns clearly but calmly to ensure you don’t inadvertently consent to overstep.

Official government resources such as U.S. Customs and Border Protection’s site (https://www.cbp.gov/) provide further information about traveler rights and inspection procedures to help you prepare.

Closing Thoughts: The Road Ahead

Phones and electronic devices have become fundamental to modern life, holding everything from personal memories to sensitive documents. While U.S. border enforcement aims to protect national security, gaps in data privacy protections remain, leaving travelers at risk of overreach.

As tools like SmartLINK and Hurricane Score expand, privacy concerns tied to electronic devices must stay at the forefront of public discourse. From minimizing on-device data to understanding your rights, being informed helps protect your privacy during crossings. However, large-scale improvements will ultimately demand stronger regulation. Until then, tools like judicial rulings and pressure from civil rights organizations provide the main bulwark against abuses.

By taking small but steady steps, individuals can play a role in shaping policies that balance security with privacy in the world’s increasingly connected age. Other posed challenges—like device encryption laws—show just how much work lies ahead. But until structural reforms materialize, travelers must exercise their options to guard against surveillance risks.
