With reports that the witnesses in today’s murder by ICE were all detained (and their phones presumably confiscated), I’ve been thinking nonstop about if I were to record ICE or the cops doing something, how could I ensure that any videos I record are not able to be deleted, assuming my phone was confiscated? I’m talking about specific tactics.
My phone runs iOS. I already have a strong passcode which hopefully makes brute forcing difficult. I use ADP and the only thing I back up automatically are photos and videos. In theory, I think my setup is fairly secure, since it would be hard to get into my phone or my iCloud account. But I don’t know what vulnerabilities or tools I may be missing.
I’m asking for iOS, but I think it’s good to discuss Android and GrapheneOS as well.
There is a deep setting on iOS for full encryption of everything. It can make it harder to retrieve your things if you forget your password but that’s exactly what you want here.
Also, on top of other great ideas. Make sure iCloud sync is on, low battery isn’t, and it should sync if it is topped up enough
OP mentioned having ADP and automatic backups enabled and I believe iCloud sync uploads photos continuously. The biggest risk is as you say battery saving and if it will upload data over mobile data (should be a setting for that).
Further than that I would say the big question is if someone else would actually be able to access the data if OP is detained… and of course https://xkcd.com/538/ (I don’t think the random chuds in ICE would have the know how for any technical bypass)
