Abstract

A recording system for securely recording an event, the system including: a capturing device for an owner to capture signals from the event, and for converting the signals into digital data; a public-key encrypting mechanism, configured to use a public key of an asymmetric key-pair, for encrypting the data into encrypted data; a non-volatile storage device for storing the encrypted data; and a private-key decrypting mechanism, configured to use a private key of the asymmetric key-pair, for decrypting the encrypted data stored in the storage device only upon using the private key, wherein the private key is securely maintained with a trusted private-key holder, and wherein the trusted private-key holder is at least one entity other than the owner of the capturing device. Preferably, the trusted private-key holder is operative to decrypt the encrypted data only upon receiving an authorization from an authorized entity.
