China Cellphones

Chinese Police are Using Cellphone Data to Track Down Protesters (cnn.com) 67

CNN reports on the aftermath of last weekend's protests against the Chinese government: A protester told CNN they received a phone call Wednesday from a police officer, who revealed they were tracked because their cellphone signal was recorded in the vicinity of the protest site.... When they denied being there, the caller asked: "Then why did your cellphone number show up there?"

In China, all mobile phone users are required by law to register their real name and national identification number with telecom providers. The protester was also told to report to a police station for questioning and to sign a written record....

In Shanghai, where some of the boldest protests took place with crowds calling for Xi's removal on two consecutive nights, police searched residents' cellphones in the streets and in the subway for VPNs that can be used to circumvent China's internet firewall, or apps such as Twitter and Telegram, which though banned in the country have been used by protesters. Police also confiscated the cellphones of protesters under arrest, according to two protesters who spoke to CNN.

A protester who was arrested over the weekend said they were told to hand over their phone and password to the police as "evidence." They said they feared police would export the data on their phone after it was confiscated by officers, who told them they could pick it up a week later. Another protester said police returned their phone upon their release, but officers had deleted the photo album and removed the WeChat social media app.

One protester told CNN they successfully avoided being contacted by the police as of Thursady afternoon.

During the demonstration, they'd kept their phone in airplane mode.

    China is currently creating the most oppressive tech-driven surveillance state the world has ever seen. Unfortunately, rather than viewing their terrifying experiment as a lesson on the dangers of failure to regard personal privacy as a right, Free World governments and their corporate owners see China as a blueprint.

          Yes, the US is doing the exact same thing as China, but only in a simplistic binary view where either the police employ all surveillance methods or none at all. It's that nonsensical binary view that is not only incorrect but very misleading.

          This story about Chinese police involves methods that are rare in the US. Yes, the US government most definitely has wide surveillance, but most of this surveillance is in the background because open surveillance is embarrassing. It's this lack of embarrassment that allows the Chinese police to openly utilize surveillance techniques that would cause trouble for US police (due to pesky enforcement of police restrictions by the courts and the press). In fact, the Chinese police want the public to know about their willingness to openly use heavy-handed techniques as a further psychological extension of their power.

            The US police don't seem embarrassed about asking Google for the personal information of everyone within a geographic area around the time a crime was suspected to have happened. That may be different to using cell tower data, but the end result is very similar.

            They primary difference seems to be which is the easiest option, not the level of comfort the police have with them.

            In both the US and Chinese cases, the justification is the same. It helps solve crime. I'm hoping that this at least makes more Chines

        • Most '89 protesters simply dispersed and went home. Few of the student protesters were arrested and went to jail and get released afterwards. Some of the formal protesters are now working with the Chinese government, for example onf of their think tanks Canrong-Jin () was a student protester at Tiananmen in 1989. You probably never heard of that because your one-sided storyteller doesn't inform you about any of this.

        That's such a cop out. The technologies were specifically carefully designed with a power asymmetry so that they could be easily monitored by the authorities. End to end encryption in cellphone systems, done at the edge as the calls exited towards the PSTN would actually be easier than the current system which decrypts when the calls arrive at the network and then re-encrypts when they go back to a cellphone. There is no neutrality in that whatsoever.

        • End to end encryption will not save you. When it started being used more in Australia they just passed legislation in 2018 mandating that all new phones have backdoors.

          Their solution was to let people have end to end encryption, but to capture every single endpoint so it does not matter.

            This situation is awful, but it's still better than having everything hard wired into the network. There are many ways it is better. A) since the thing happens on the local terminal and is a bit abnormal it is possible for journalists who realise that they are being spied on to investigate and prove it's happening B) it becomes possible to buy devices from elsewhere and use them instead of Australian bought devices C) you can build your own software (e.g. LineageOS) and use that.

      They don't need any such thing. The government controls the telcos, they can just ask them for the location data.

    • The takeaway is airplane mode helps but is not necessarily risk free. So how can they organize anonymously? Leave your main cellphone off or at home. Reformatting NFC devices for mesh networks. But having one is suspicious. China might be infeasible but a lesson for democracy that freedom can be squashed.

        Difficult situation, because if you're not happen to carry your tracking device around with you, that can already make you look suspicious.
        Because "nothing to hide, nothing to fear" rhetoric would have it that there can be no other explanation for you not carrying your tracker than you being up to something where carrying your tracker would be a bad idea.

        The future of retaining some degree of anonymity might be to hide in plain sight, perhaps with methods adjacent to chaffing and winnowing.

        Let's completely avoid discussion about the issues and focus on the journalist asking questions. She's completely rightwing, you know, and that makes all the issues about Apple OK.

        Let's also forget that ESG is a thing, liberals claim to care about governance and social issues, companies are rated by their ESG rating, and companies are regularly boycotted by liberals for social offenses, but somehow not Apple for doing this.

        Let's focus on the real issues here.

        The feature "AirDrop" was restricted by pushing an update, the update didn't state that this (the restriction) would happen, and the restriction happened only for phones in mainline China. This wasn't a mistake, happened on purpose, and directly hobbled protests against human rights violations in an authoritarian regime.

        From previous Slashdot story:

        That changed on Nov. 9, when Apple released a new version of its mobile operating system, iOS 16.1.1, to customers worldwide. Rather than listing new features, as it often does, the company simply said, "This update includes bug fixes and security updates and is recommended for all users." Hidden in the update was a change that only applies to iPhones sold in mainland China: AirDrop can only be set to receive messages from everyone for 10 minutes, before switching off. There's no longer a way to keep the "everyone" setting on permanently on Chinese iPhones.

        The change, first noticed by Chinese readers of 9to5Mac, doesn't apply anywhere else.

    Every generation has to learn this same lesson [fee.org], and it's hard every time. Freedom of speech is painful and messy, but we have it for a reason. Yes it sucks that people can say factually untrue things and the government won't stop them. But there is no magical group of unbiased fairies that know the whole truth, only a few groups that think they do. Better to live with fake news than hand over control of what you hear to the government. Oh, and letting unregulated private organizations decide what's true (like social media and cable news) is just as dumb. At least broadcast news used to be pseudo-regulated by the fairness doctrine. We lost something valuable when we gave that up.

    It would actually be less suspicious to leave the phone on but at your home rather than to place it in airplane mode. Although they are not likely searching for phones that suddenly stopped pinging in the wider area rather than just a geolocation report, but I wouldn't put it past them to do that if they wanted to be very thorough.

    The main issue is that they also have cameras and facial recognition, which still requires additional steps to frustrate. The fact that they are protesting in such large numbers is the biggest help. Once it reaches a tipping point, individual safety actually increases.
