Self Protecting Digital Content (SPDC), is a copy protection (Digital Rights Management) architecture which allows restriction of access to, and copying of, the next generation of optical discs and streaming/downloadable content.Designed by Cryptography Research, Inc. of San Francisco, SPDC executes code from the encrypted content on the DVD player, enabling the content providers to change DRM systems in case an existing system is compromised. It adds functionality to make the system "dynamic", as opposed to "static" systems in which the system and keys for encryption and decryption do not change, thus enabling one compromised key to decode all content released using that encryption system. "Dynamic" systems attempt to make future content released immune to existing methods of circumvention.
