DEEPFAKE ATTACK IDENTIFICATION SYSTEM

A method, computer program product and a system for video authentication comprising: a capturing-device configured to continuously capture media, a real-time instruction module configured to provide instructions to the capturing-device causing it to change, in real-time, an operation mode while capturing a media segment, a signing module configured to create, in real-time, signature for the media segments and transmit the to a storage module retaining pairs of a signature of a media segment, and respective instructions that were provided to the capturing-device while capturing the media segment. The media authenticity verification module receives a media segment to determine authenticity of the media segment by obtaining a respective pair of a signature and instructions; utilizing the signature to ensure that the media segment was not manipulated after being captured; and verifying that the media segment complies with the instructions, whereby protecting against potential deepfake attacks.
