fw:不計前嫌， 想搵人一起發逹。

某人兄

1. 拍完條片，改完
2. 搵部電腦播返出嚟，個HDMI接落去USB Capture Card
3. 個App以為係真係Camera，錄嘅時候會幫佢加返signature
4. 疑幻似真勝過真完成

個android app 應該會close source,
我可以強迫佢只接受信得過的video.
e.g. 有signature 的鏡頭等等 ...

The procedures proposed by CAI and C2PA address the widespread occurrence of disinformation with a set of additional data (metadata) containing details about the provenance of information displayed on a digital device. Such information can be, for example, a photo, video, sound or text file. The C2PA metadata for this information can include, among other things, the publisher of the information, the device used to record the information, the location and time of the recording or editing steps that altered the information. To make sure that the C2PA metadata can not be changed unnoticed, it is secured with hashcodes and certified digital signatures. The same applies to main content of the information, such as a picture or a text. A hash code of that data is stored in the C2PA metadata section and then, as part of that metadata, secured with the digital signature.
