On device content scanning notifies Snapchat of a certain type of threat, that + metadata goes to a real-time law-enforcement system which combines it with other sources to decide whether a lawful intercept is warranted - if so, Snapchat pulls the cached messages off the device and forwards them on.
It’s arguable that would be reasonable and legal, depending on the watchlist.
- CryptoBanker 3y agoOn device scanning would be reasonable? What happened when everybody was up in arms about Apple wanting to do on device scanning for child porn?
- implements 3y agoWell - it’s reasonable for a government to seek to stop absolute privacy subverting the prevention and detection of crime … I think, so a state has to find some way to be able to construct reasonable suspicion and then lawful search on routine internet activity.
