Abstract: An encryption box device has a memory and a processor coupled to the memory. A first clipboard runs on the processor and downloads a plaintext stream. An encryption engine runs on the processor and receives the plaintext stream and encrypts the plaintext stream to produce an encrypted stream. A digitizer runs on the processor and digitizes the encrypted stream to produce a digitized encrypted stream. A second clipboard runs on the processor and uploads the digitized encrypted stream. The encryption engine may also decrypt the encrypted stream to produce the plaintext stream and upload the plaintext stream to the first clipboard.

Abstract: An object is protected from unauthorized copying by providing a key generator for the object, producing a first key, second key and a lock for the keys, storing the first key in the object, storing the second key in a database separate from the object, reading the first and second keys, opening the lock with the first and second keys, producing a third and fourth keys and a new lock for the object, invalidating the first and second keys, replacing the first key in the object with the third key, and replacing the second key in the database with the fourth key.
