Protecting against deepfake attacks

A system comprising:

• a capturing device configured to continuously capture media, said capturing device capturing multiple timestamped media segments;
• a real-time instruction module that is configured to provide real-time instructions to said capturing device, each of the real-time instructions is configured to cause said capturing device to change, in real-time, an operation mode while capturing a respective timestamped media segment, thereby causing a mode change for the capturing device, the mode change is configured to affect captured media segment in a manner that is identifiable by a media authenticity verification module;
• a real-time signing module that is configured to create, in real-time, signatures for the multiple timestamped media segments, said real-time signing module is configured to transmit the signatures for the multiple timestamped media segments to a storage module;
• said storage module, wherein said storage module is configured to retain pairs of a signature of a timestamped media segment, and respective one or more real-time instructions that were provided to said capturing device by said real-time instruction module while capturing the timestamped media segment;
• said media authenticity verification module, wherein said media authenticity verification module is configured to receive a media segment for analysis to determine whether the media segment is authentic or not, said media authenticity verification module is configured to determine authenticity of the media segment by:
• obtaining from said storage module a pair of a signature and one or more 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 one or more instructions, whereby protecting against potential deepfake attacks.
