Reminds me of this RadioLab episode about a company that loiters over areas with a high resolution imaging platform that allows them to &#x27;rewind&#x27; from the scene of a crime to see where the suspects came from:<p><a href="https:&#x2F;&#x2F;radiolab.org&#x2F;episodes&#x2F;update-eye-sky" rel="nofollow">https:&#x2F;&#x2F;radiolab.org&#x2F;episodes&#x2F;update-eye-sky</a><p>The company in question:<p><a href="https:&#x2F;&#x2F;www.pss-1.com&#x2F;" rel="nofollow">https:&#x2F;&#x2F;www.pss-1.com&#x2F;</a>

The concept and visualization reminds me a lot of similar technology in the TV show Person of Interest. <a href="https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Person_of_Interest_(TV_series)" rel="nofollow">https:&#x2F;&#x2F;en.m.wikipedia.org&#x2F;wiki&#x2F;Person_of_Interest_(TV_serie...</a><p>It&#x27;s quite interesting to think about how relevant the themes being discussed in that show are ever present today.

I highly doubt AI is being used here to match up the Open Camera footage with the instagram pic. Identifing humans as an object within a frame is trivial. Identifying individuals requires a considerable amount of custom training which is more than what is available from an instagram pic and a few video frames. I&#x27;m not saying it can&#x27;t be done, it&#x27;s just not that easy. I&#x27;d bet $100 bucks that most, if not all, of these matches were accomplished using good old stalking (matching post times to manually reviewing video data). Would be happily proven wrong but without any source code provided I stand firm with my opinion.

&gt; OMG that&#x27;s the most terrifying thing I have seen in ages.<p>Too late.<p>NTechLab scraped vk.com (Facebook-like Russian social network) profile photos and were running a public website &quot;FindFace&quot; that allowed to find profiles by photo of a face. They provide services to Russian government, e.g. it&#x27;s used to find people from protests. Also FindFace was used to find and harass webcam models.<p><a href="https:&#x2F;&#x2F;www.businessinsider.com&#x2F;intel-spacex-philip-morris-leaked-database-users-ntech-russian-facial-recognition-company-2022-7" rel="nofollow">https:&#x2F;&#x2F;www.businessinsider.com&#x2F;intel-spacex-philip-morris-l...</a><p>&gt; Intel, SpaceX, Philip Morris, and dozens of other US companies were in a leaked database of users for a Russian facial recognition company<p>&gt; The NTech Lab user list, which was shared with Insider by an anonymous source, includes more than 1,100 entries, with businesses and government agencies from more than 60 countries.<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;FindFace" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;FindFace</a><p>&gt; In 2017, NtechLab face recognition algorithms were built into the Moscow city video surveillance system operated by the Moscow Department of Information Technology . The system uses the database of the Ministry of Internal Affairs to find correspondences to it on video. The alleged use of the system is the search for criminals and the fight against terrorism.<p>&gt; In 2022, NTechLab was accused of assisting the Russian and Belarus government by tracking thousands of political activists which led to their unconstitutional detentions and arrests.<p>&gt; In 2016, FindFace generated controversy because it was once used to deanonymize Russian pornography actresses and alleged prostitutes. These efforts were organized by users of a Russian imageboard Dvach who claimed that women in the sex industry are “corrupt and deceptive”, according to Global Voices. In addition, FindFace has been characterized as a major step in the erosion of anonymity.

Looks like the website is down, here&#x27;s the YouTube video about the project: <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=sd_P0LxIBGI" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=sd_P0LxIBGI</a>

Some people put a lot more effort into their photos than I do! Although as they selected people with 100k+ followers I guess taking good photos is basically work for them (or rather their patient partners).

What does &quot;open camera&quot; mean? Public webcam? Hacked CCTV? How did the author find those cameras?

I realised what they were doing on the second photo&#x2F;video.<p>OMG that&#x27;s the most terrifying thing I have seen in ages.<p>Amazing, innovative, tipping-point-sign, but still, terrifying

Man, that is creepy as hell. Perhaps it can be useful to really bring home to people how they&#x27;re being spied on every day.

This is a mixed bag of both good and bad. Imagine a domestic violence victim being tracked&#x2F;stalked by their abusive partner. Conversely, allowing citizens to monitor these cameras could potentially help prevent&#x2F;solve crimes. In the end, it&#x27;s probably a Constitutional dilemma that will find it&#x27;s way into the high courts someday soon.

Some of the photographers and subjects seem to know exactly the right angles to appear more &quot;fit.&quot;

Great project.<p>Is the code for this project or similar projects available on Github?<p>The unstated implications of all this are unsettling.

That is actually pretty freaking cool. Not hard to do by any means, just cool.

Can someone explain to a novice how “AI” is used here? Is the person in the IG image being correlated to a security camera time stamp with face recognition or similar?

I wonder what the storage requirements for video from multiple traffic cameras for weeks is? A few TB per day?

very thought-provoking - people think only a portion of what they’re doing is shared, but government sees all

Not gonna lie, I thought of this becoming possible with advent of AI &amp; constant stream of social media posting.<p>You could also the reverse and find social media posts from the CCTV footage, to capture some passerby&#x27;s face at a higher resolution.<p>We are living in dystopian times.

Combine this with Grassland for a crowded mass surveillance system<p><a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=19529921" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=19529921</a>

This is horrifying. Insta should require government ID to view so if you stalk &#x2F; kill someone the police can quickly narrow down the set of possible perpetrators and find you.

This is why I have no social media accounts. No one knows what I am up to. No one knows where I have been. No one can find me.<p>Do not track is now a lift style.
