Abstract:
1. An apparatus having a digital protection mechanism, comprising: a tangible object; a digital protection system physically attached to said tangible object, said digital protection system comprising: (a) an external interface for receiving data requests; (b) a processor coupled to said external interface, said processor capable of transforming data according to a first public/private key encryption algorithm; and (c) an internal data storage, said internal data storage storing an identity private key, said identity private key being inaccessible outside said external interface; and a data descriptor associated with said digital protection system, said data descriptor including an identity public key, attribute data and a digital signature, said digital signature protecting said data descriptor, said attribute data comprising at least one attribute of said tangible object; wherein said processor performs a first transformation of data responsive to a request received through said external interface, said processor performing said first transformation of said data according to said first public/private key encryption algorithm using said identity private key, wherein a second transformation of data according to said first public private key encryption algorithm using said identity public key is a complementary transformation of said first transformation.
