The Body Cam Hacker Who Schooled the Police
New submitter Cuillere writes: In the fall of 2014, a hacker demanded the Seattle Police Department release all of their body and dash cam video footage, prompting chaos within the institution. Although it was a legal request per Washington state's disclosure laws, Seattle's PD wasn't prepared to handle the repercussions of divulging such sensitive material — and so much of it. The request involved 360 TB of data spread across 1.6 million recordings over 6 years. All recordings had to be manually reviewed and redacted to cut out "children, medical or mental health incidents, confidential informants, or victims or bystanders who did not want to be recorded," so fulfilling the request was simply not within the department's capabilities. Thus, they took a different strategy: they hired the hacker and put him to work on developing an automated redaction system. "Their vision is of an officer simply docking her body cam at the end of a shift. The footage would then be automatically uploaded to storage, either locally or in the cloud, over-redacted for privacy and posted online for everyone to see within a day."
No, he is indeed part of the problem.
If a software can automatically redact the footage based on non-trivial criteria, then it can also run all sorts of metadata collection, turning every single policeman into a walking surveillance device. If you see a policeman on the street, then your location will be recorded, tied to your identity and stored forever.
Of course, it's possible that this happens already...
