ASYMMETRICAL ENCRYPTION OF STORAGE SYSTEM TO PROTECT COPYRIGHT AND PERSONAL INFORMATION

摘要

Robust security of copyright-protected content is provided when such content is digitally stored in a storage device of a client device in encrypted form. The copyright-protected content is encrypted by a server device using a private key and a corresponding public key is used for decryption by the client device. Because access to the private key cannot be determined from the corresponding public key, and because the private key and public key are based at least in part on a unique ID number embedded in the data storage device, decryption can only be performed by the data storage device in the client device. In some embodiments, robust security of private data stored in a server device is provided using a similar public-key/private-key pair and encryption scheme.
