Twitter yanks data feeding tube out of police surveillance biz

Tracking for marketing, that's fine – but the cops? No way

Updated Twitter has suspended its commercial relationship with a company called Geofeedia – which provides social media data to law enforcement agencies so that they can identify potential miscreants.

The social media company announced the change through its Policy account on Tuesday morning following the publication of a report by the American Civil Liberties Union (ACLU) of California.

The civil liberties advocacy organization obtained records indicating that Facebook, Instagram, and Twitter provided bulk user post data to Geofeedia, which markets its social media monitoring software to law enforcement agencies as a way to track activists, among other uses.

Following reports alleging increased use of social media surveillance last month, both Facebook and its Instagram division ceased providing data to Geofeedia on commercial terms. Facebook did not respond to a request to provide further details.

According to the ACLU, while Twitter did not supply its full-spectrum "Firehose" data access, it did offer Geofeedia access to its database of public tweets through a subsidiary. Twitter tried to impose limitations on the arrangement in February, and when that didn't achieve the desired results, it sent a cease-and-desist letter.

Evidently, that didn't work either. On Tuesday, Twitter said, "Based on information in the @ACLU's report, we are immediately suspending @Geofeedia's commercial access to Twitter data."

Geofeedia did not respond to email or a call seeking comment.

Asked for comment, a Twitter spokesperson in an email to The Register pointed to the company's Policy post and to a May article in The Wall Street Journal indicating that Twitter directed Dataminr, an analytics firm in which it has invested, to stop sharing data with US intelligence agencies.

The ACLU contends that social media surveillance is becoming more common among law enforcement agencies and that it "can disproportionately impact communities of color." The organization cites law enforcement use of Geofeedia data in Oakland and Baltimore as examples.

According to the Baltimore Sun, police have acknowledged the use of Geofeedia data to monitor protests, public events, and incidents of community concern. They insist that they only monitor public posts.

If social media monitoring among law enforcement agencies is becoming more common, it's not yet ubiquitous. In an email to The Reg, San Francisco Police Department officer Jennifer Nguyen said, "The SFPD Media Relations unit monitors social media by utilizing TweetDeck. However, SFPD Investigations does not use any social media monitoring tools."

Facebook, Instagram, and Twitter place limits on how site data can be accessed through their terms of service agreements. In general, they forbid scraping data without prior consent, because they make bulk data available on commercial terms. They also allow developers to access data through APIs. The rate at which such data can be obtained is typically limited in the absence of a commercial agreement.

An email from Geofeedia obtained by the ACLU as a public record suggests that its arrangement with Instagram provided it with the ability to gather user data at a rate ten times greater than it would have been able to manage without a contractual deal.

The ACLU observes that while neither Facebook nor Instagram have policies forbidding the use of user data for surveillance, Twitter does have such a policy.

The advocacy organization is seeking:

  • Stronger measures to prevent social media companies from providing data to developers of surveillance tools.
  • Clearer policies spelling out such prohibitions.
  • More effective oversight of developers through human and automated compliance checks.

Separating developers of marketing tools from developers of surveillance tools, however, may not be easy.

In a phone interview with The Register, Nicole Ozer, technology and civil liberties policy director of the ACLU of California, said Geofeedia "marketed its surveillance software in part to target activists and protesters."

Beyond such dubious marketing, Ozer said Geofeedia is problematic because it provides automated access to data beyond what the law enforcement agencies could do on their own. "They're getting billions of posts packaged in a way that allows them to monitor and target for very specific surveillance purposes," she said.

Yet the implication here – that authorities have to sort through posts by hand – seems like a bit too much to ask ®.

Updated to add

In a statement sent to The Reg after this story was filed, Geofeedia CEO Phil Harris said that a wide range of public and private sector organizations use the company's software, and in each case, the company is committed to privacy and transparency.

"Our platform provides some clients, including law enforcement officials across the country, with a critical tool in helping to ensure public safety while protecting civil rights and liberties," said Harris, citing its use in emergency response and recovery efforts such as the Boston Marathon and Hurricane Matthew.

"Geofeedia has in place clear policies and guidelines to prevent the inappropriate use of our software; these include protections related to free speech and ensuring that end users do not seek to inappropriately identify individuals based on race, ethnicity, religious, sexual orientation or political beliefs, among other factors," the statement continues.

"That said, we understand, given the ever-changing nature of digital technology, that we must continue to work to build on these critical protections of civil rights. Geofeedia will continue to engage with key civil liberty stakeholders, including the ACLU and the law enforcement community, to make sure that we do everything in our power to support the security of the American people and the protection of personal freedoms."

    So cool you're into free speech because that includes taking down misinformation

    While the US Supreme Court considers an emergency petition to reinstate a preliminary injunction against Texas' social media law HB 20, the US Eleventh Circuit Court of Appeals on Monday partially upheld a similar injunction against Florida's social media law, SB 7072.

    Both Florida and Texas last year passed laws that impose content moderation restrictions, editorial disclosure obligations, and user-data access requirements on large online social networks. The Republican governors of both states justified the laws by claiming that social media sites have been trying to censor conservative voices, an allegation that has not been supported by evidence.

    Multiple studies addressing this issue say right-wing folk aren't being censored. They have found that social media sites try to take down or block misinformation, which researchers say is more common from right-leaning sources.

  • US-APAC trade deal leaves out Taiwan, military defense not ruled out
    All fun and games until the chip factories are in the crosshairs

    US President Joe Biden has heralded an Indo-Pacific trade deal signed by several nations that do not include Taiwan. At the same time, Biden warned China that America would help defend Taiwan from attack; it is home to a critical slice of the global chip industry, after all. 

    The agreement, known as the Indo-Pacific Economic Framework (IPEF), is still in its infancy, with today's announcement enabling the United States and the other 12 participating countries to begin negotiating "rules of the road that ensure [US businesses] can compete in the Indo-Pacific," the White House said. 

    Along with America, other IPEF signatories are Australia, Brunei, India, Indonesia, Japan, South Korea, Malaysia, New Zealand, the Philippines, Singapore, Thailand and Vietnam. Combined, the White House said, the 13 countries participating in the IPEF make up 40 percent of the global economy.

  • 381,000-plus Kubernetes API servers 'exposed to internet'
    Firewall isn't a made-up word from the Hackers movie, people

    A large number of servers running the Kubernetes API have been left exposed to the internet, which is not great: they're potentially vulnerable to abuse.

    Nonprofit security organization The Shadowserver Foundation recently scanned 454,729 systems hosting the popular open-source platform for managing and orchestrating containers, finding that more than 381,645 – or about 84 percent – are accessible via the internet to varying degrees thus providing a cracked door into a corporate network.

    "While this does not mean that these instances are fully open or vulnerable to an attack, it is likely that this level of access was not intended and these instances are an unnecessarily exposed attack surface," Shadowserver's team stressed in a write-up. "They also allow for information leakage on version and build."

  • A peek into Gigabyte's GPU Arm for AI, HPC shops
    High-performance platform choices are going beyond the ubiquitous x86 standard

    Arm-based servers continue to gain momentum with Gigabyte Technology introducing a system based on Ampere's Altra processors paired with Nvidia A100 GPUs, aimed at demanding workloads such as AI training and high-performance compute (HPC) applications.

    The G492-PD0 runs either an Ampere Altra or Altra Max processor, the latter delivering 128 64-bit cores that are compatible with the Armv8.2 architecture.

    It supports 16 DDR4 DIMM slots, which would be enough space for up to 4TB of memory if all slots were filled with 256GB memory modules. The chassis also has space for no fewer than eight Nvidia A100 GPUs, which would make for a costly but very powerful system for those workloads that benefit from GPU acceleration.

  • To multicloud, or not: Former PayPal head of engineering weighs in
    Not everyone needs it, but those who do need to consider 3 things, says Asim Razzaq

    The push is on to get every enterprise thinking they're missing out on the next big thing if they don't adopt a multicloud strategy.

    That shove in the multicloud direction appears to be working. More than 75 percent of businesses are now using multiple cloud providers, according to Gartner. That includes some big companies, like Boeing, which recently chose to spread its bets across AWS, Google Cloud and Azure as it continues to eliminate old legacy systems. 

    There are plenty of reasons to choose to go with multiple cloud providers, but Asim Razzaq, CEO and founder at cloud cost management company Yotascale, told The Register that choosing whether or not to invest in a multicloud architecture all comes down to three things: How many different compute needs a business has, budget, and the need for redundancy.
