Abstract
This invention relates to system for securing an information unit and applications thereof. The system comprising at least one encrypting means for applying a first encryption key to the information unit thus provided an encrypted information unit, wherein said at least one encryption means is adapted to apply at least two second information encryption keys to the encrypted information unit, said at least two second encryption keys being calculated so as to decrypt the encrypted information unit when all of said first and second encryption keys have been applied to the information unit, the encryption keys being distributed to chosen users of the system.
Claims7
