Method and apparatus for the secure storage of audio signals |
摘要 |
A method and apparatus for recording audio so that the recording can be authenticated as to both content and time of recording is provided. The system may be implemented as a central server that is accessed via one or more telephone lines, or as a stand-alone unit. The system operates by encrypting audio information, storing the encrypted information, and providing users with a cryptographic key that can be used to decrypt the stored information. Preferably, time stamps are embedded in the stored information. Digital signatures may be used to provide additional security.
