It’s pretty standard practise these days to have some form of secure enclave on an SoC - Arm’s TrustZone, Intel’s SGX, AMD’s SME/SEV. This wouldn’t be any different. Many camera ICs are already using an Arm CPU internally already.

As with everything, trust is required eventually. It’s more about reducing the amount of trust required than removing it entirely. It’s the same with HTTPS - website certificates only work if you trust the root certificate authorities, for example. Root manufacturer keys may only be certified if they have passed some level of trust with the root authority/authorities. Proving that trust is well-founded is more a physical issue than an algorithmic one. As it is with root CAs it may involve physical cybersecurity audits, etc.

This is just standard public key cryptography, we already do this for website certificates. Your browser puts a little lock icon next to the URL if it’s legit, or provides you with a big, full-page warning if something’s wrong with the cert.

You, the end user, don’t have access to your camera’s private key. Only the camera IC does. When your phone / SD card first receives the image/video it’s already been signed by the hardware.
- Comment on Anon predicts the future 1 week ago:
Video evidence is relatively easy to fix, you just need camera ICs to cryptographically sign their outputs. If the image/video is tampered with (or even re-encoded) the signature won’t match. As the private key is (hopefully!) stored securely in the hardware IC taking the photo/video, any generated images or videos can’t be signed by such a private key.
- Comment on Todd Howard Reaffirms Bethesda Is Currently Developing The Elder Scrolls 6 2 months ago:
Call me cynical, but I firmly believe that ES6 is more useful to Bethesda as a perpetual ‘carrot on a stick’ than anything they would get from actually releasing it. The people that made Morrowind, Oblivion, and even Skyrim what they are no longer work at Bethesda, but the goodwill of the series remains in people’s minds, and they associate that with Bethesda, even if a majority of their modern releases have been dumpster fires for one reason or another.
There’s a reason we’ve gone almost 15 years without a mainline elder scrolls game, and I’m pretty sure it’s because even Bethesda knows that they likely can’t capture that magic again.
- Comment on Grand Theft Auto Online Reportedly Broken On Steam Deck 9 months ago:
GTA online took ages to load, like 10+ minutes on some machines. One guy got really annoyed and investigated. It turned out to be loading a single 10MB JSON file in an incredibly inefficient manner. The JSON file contains about 60,000 items and they need to extract each item from it, but every time they look for the next item they start from the beginning of the file again, despite already knowing where they found the previous item! All the entries in the JSON list are unique, but the code also checks for any duplicate entries, of course it’s also done in the least efficient way possible requiring 1,984,531,500 comparisons for something that has no effect. Not only did this one person find these problems but he also implemented a fix that reduced load times by 70% as a result, shaving off more than 7 minutes of load times for some machines. The fact that Rockstar didn’t notice this is frankly shocking and speaks to the fact that they really just don’t care.
