We need to push for a new standard in #CryptographicCamera technology, where every camera has a built-in #TPM and uses its own unique, immutable key to #CryptographicallySign every photo and every frame of every video that it shoots.
That way, if someone claims to have photo/video evidence of a crime being committed, they can prove its authenticity by submitting the #CryptoCamera along with the evidence it allegedly captured.
Of course, these cameras would need to close the #AnalogHole, perhaps by disabling the signing feature whenever they are shooting a screen of any kind (TV/monitor, projector, phone, tablet, etc.), though other countermeasures should be explored as well. And yes, it would be theoretically possible for a determined and sophisticated attacker to spoof the #CryptographicSignature and make a #deepfake appear as if it had been signed by a #CryptoCam, but that would be a significantly higher barrier to entry than simply creating the deepfake itself.
