• Many sections of Baltimore are under secret, constant aerial video surveillance by BPD

    The Baltimore Police Department has secretly deployed a surveillance system using planes and powerful cameras that can continuously record 30-square-mile sections of the city at once. The technology, which is run by a private company, was originally developed for the Defense Department for use in Iraq. It stores the video footage for an undetermined amount of time, and police can use it to retroactively track any pedestrian or vehicle within the surveillance area.

  • Android apps can secretly track users’ whereabouts

    Three years ago, the FTC dimmed hopes for the Brightest Flashlight app for Android, slapping its developer with charges of consumer deception, because the app was transmitting users’ locations and device IDs to third parties without telling the users or getting their permission. Permissions, though, are only a small part of the Android-app privacy story. New research shows that Android apps can be manipulated to reach inside your mobile phone to track your whereabouts and traffic patterns, all without your knowledge or consent.

  • Protecting privacy in genomic databases

    By Larry Hardesty

    Genome-wide association studies, which try to find correlations between particular genetic variations and disease diagnoses, are a staple of modern medical research. But because they depend on databases that contain people’s medical histories, they carry privacy risks. An attacker armed with genetic information about someone — from, say, a skin sample — could query a database for that person’s medical data. Researchers describe a new system that permits database queries for genome-wide association studies but reduces the chances of privacy compromises to almost zero.

  • Live-streaming crime incidents a challenge U.S. privacy law

    In July, the fatal police shootings of Alton Sterling and Philando Castile went viral on social media. The aftermath of the Castile shooting was first shared via Facebook Live, which is a type of mobile streaming video technology (MSVT) that allows users to stream live video to followers, similar to Periscope and Meerkat. The two incidents focus attention on the legal rights of people to record and live stream and any potential right to be free from being recorded and streamed in public places.

  • DHS S&T awards $3.66 million for privacy-enhancing technology R&D

    DHS S&T has announced the award of three contracts totaling $3.66 million to fund the research and development of privacy-enhancing technologies that better defend personally identifying information and protect privacy in cyber space.

  • Protecting against “browser fingerprint”

    Imagine that every time a person goes out in public, they leave behind a track for all to see, so that their behavior can be easily analyzed, revealing their identity. This is the case with people’s online browser “fingerprints,” which are left behind at each location they visit on their internet browser. Almost like a regular fingerprint, a person’s browser fingerprint — or “browserprint” — is often unique to the individual. Such a fingerprint can be monitored, tracked, and identified by companies and hackers.

  • How to stay anonymous online

    By Larry Hardesty

    Anonymity networks protect people living under repressive regimes from surveillance of their Internet use. But the recent discovery of vulnerabilities in the most popular of these networks — Tor — has prompted computer scientists to try to come up with more secure anonymity schemes. These scientists have developed a new anonymity scheme that provides strong security guarantees but uses bandwidth much more efficiently than its predecessors, making it possible for network to protect users’ anonymity if all but one of its servers are compromised.

  • Your smart watch and fitness tracker may give away your PIN

    Wearable devices — Fitbits, Jawbones, Nike+, Apple Watches, and the like — are white-hot. The tech segment is already producing an estimated $14 billion in sales worldwide, and expected to more than double within four years, climbing to north of $30 billion. But a new research report reveals those cool wearables just may leak information as you use them.

  • House committee releases encryption report, laying foundation for a national dialogue

    Terrorist attacks in Paris and San Bernardino have sparked a public debate on the use of encryption in the United States because the attackers used encrypted communications to evade detection, a phenomenon known as “going dark.” Earlier this week, the Majority Staff of the House Homeland Security Committee released a new report, titled Going Dark, Going Forward: A Primer on the Encryption Debate. The summarizes the committee’s findings, based on more than 100 meetings and briefings committee staff and members have held with key stakeholders over the past year.

  • Weak spots in Europe’s “Right to be Forgotten” data privacy law

    Under Europe’s “Right to be Forgotten” law, citizens there can petition Internet search providers such as Google to remove search results linked to personal information that is negative or defamatory. In many cases, these links lead to information about accusations of criminal activity or financial difficulties, which may be “delisted” if the information is erroneous or no longer relevant. But “gone” doesn’t always mean “forgotten,” according to a new study.

  • You are not as anonymous online as you may think

    Hiding online is harder than you would have thought. You may not be anonymous as you think you are online, reveals a new study. Your browsing behavior can indicate your personality and provide a unique digital signature which can identify you, sometimes after just 30-minutes of browsing.

  • Snowden performed “public service” but should be punished: Eric Holder

    Eric Holder, the former U.S. Attorney General, has said Edward Snowden performed a “public service” by triggering a debate over surveillance techniques. Holder added, however, that he believed Snowden should be punished for leaking classified intelligence information which threatened U.S. national security.

  • We know where you live

    By Larry Hardesty

    Researchers have shown that the location stamps on just a handful of Twitter posts — as few as eight over the course of a single day — can be enough to disclose the addresses of the poster’s home and workplace to a relatively low-tech snooper. The tweets themselves might be otherwise innocuous — the location information comes from geographic coordinates automatically associated with the tweets.

  • Telephone metadata can reveal surprisingly sensitive personal information

    Most people might not give telephone metadata – the numbers you dial, the length of your calls – a second thought. Some government officials probably view it as similarly trivial, which is why this information can be obtained without a warrant. Researchers show, however, that telephone metadata – information about calls and text messages, such as time and length – can alone reveal a surprising amount of personal detail. The work could help inform future policies for government surveillance and consumer data privacy.

  • Snowden revelations led to “chilling effect” on pursuit of knowledge: Study

    By Nadia Prupis

    National Security Agency (NSA) whistleblower Edward Snowden’s 2013 mass surveillance revelations caused a drop in website browsing, particularly in internet searches for terms associated with extremism, an example of the most direct evidence yet that the spying operations exposed in the leak had a “chilling effect” on the lawful pursuit of information, an impending report has found.
