By creating an optical device that is held in front of the face, we can make it difficult for any attacker to deepfake a person. This is because the deepfake algorithm will not be trained, and likely cannot be trained, to overcome every possible optical interference. Ultimately, these devices will be able to receive input, making them even more challenging to overcome.
It also uses the same signing method as the anti-deepfake headset. Where the package is signed by the account holder signed again by the resident then sealed in a tamper-proof device. This means the attacker has to both get access to the reality anchor package along with getting access to
