Abstract

This paper present a method to distribute the security key used to encrypt digital content by embedding the security key as a watermark into a digital sample that is appended to the encrypted digital content. The security key embedded into the sample is imperceptible and can not be detected by attackers. To play or read digital content, a portable device will extract the security key from the sample, then use the detected key to decrypt the encrypted content. This paper also present a method to generate and transfer right between clearing hose and portable device and between two portable devices. In order to prevent digital content from being illegally used, authentication, and verification between clearing house and portable device and between two portable devices are employed. The right information is tamper-resistent when it is transferred to portable devices. This method can maximally protect the usage of digital contents even if the portable device is breached.
