Functionality and control of the media module using a method and apparatus for access and compatibility control is disclosed. The media module interfaces with a camera or other device to store image and audio data from the camera on memory. Access to the media module is controlled by method and system for data encryption or authentication. Encryption or authentication controls access and compatibility with particular camera, camera line, or camera manufacture. The encryption or authentication may also control access to features or functions of the media module. An authentication module comprising an input/output controller, processor and memory processes an authentication request or command to determine if the media module and camera are compatible. The processor may execute software stored on the memory to perform any type of authentication including a hash operation, symmetric key operation, or asymmetric key operation.
