Showerthoughts

A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. The most popular seem to be lighthearted clever little truths, hidden in daily life.
Here are some examples to inspire your own showerthoughts:
- Both “200” and “160” are 2 minutes in microwave math
- When you’re a kid, you don’t realize you’re also watching your mom and dad grow up.
- More dreams have been destroyed by alarm clocks than anything else
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- No politics
- If your topic is in a grey area, please phrase it to emphasize the fascinating aspects, not the dramatic aspects. You can do this by avoiding overly politicized terms such as "capitalism" and "communism". If you must make comparisons, you can say something is different without saying something is better/worse.
- A good place for politics is c/politicaldiscussion
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct and the TOS
If you made it this far, showerthoughts is accepting new mods. This community is generally tame so its not a lot of work, but having a few more mods would help reports get addressed a little sooner.
Whats it like to be a mod? Reports just show up as messages in your Lemmy inbox, and if a different mod has already addressed the report, the message goes away and you never worry about it.

This is a terrible idea. So of course it already exists https://c2pa.org/
It's already being exploited https://www.da.vidbuchanan.co.uk/blog/android-c2pa.html
We need a solution but that's not it.
I assume that scheme is part of a long-term effort from Google to reinforce the idea that nobody but them should be allowed to have root on their phones, and is therefore working as intended.
That would be my guess as well.
The article criticizes software Attestation which is valid criticism but if the Attestation happened in the camera chip itself and not at OS level then even a rooted system would not be able to cheat a certificate
A rooted phone could not, but anyone with a bottle of acid and a microscope could. Or as I've said, a nice optics setup and a high quality projector.
My point being that trusting the camera chip does not help much. But, of course, it would block the easiest software attacks like we have seen so far.
Oh neat, i had no idea it was a thing already. What is a better idea?
Neat - so maybe point and click devices get to make a comeback, or the CCD itself could sign.
I'm not a researcher in this field, so I don't have anything substantial to suggest. My opinion is that it is unsolvable.
No matter what you try, sufficiently powerful entities will be able to modify the sensor to sign images of anything they want to pass as real (or just use a very high quality projector)
It might be better that we are all always weary of an image being AI at this point.
It's the same thing as with "watermarking" music files - it's a bunch of hot air, anybody anywhere can just play them back and recapture the analog, and if the watermark survives that then it's absolutely going to be audible.
