A secure repository individualized for a hardware environment and a method and system for providing the same. The secure repository includes a hidden cryptographic key and code that applies the key without requiring access to a copy of the key. The code that implements the secure repository is generated in a manner that is at least partly based on a hardware ID associated with the hardware environment in which the secure repository is to be installed, and may also be based on a random number. Cryptographic functions implemented by the secure repository include decryption of encrypted information and validation of cryptographically signed information. The secure repository may be coupled to an application program, which uses cryptographic services provided by the secure repository, by way of a decoupling interface that provides a common communication and authentication interface for diverse types of secure repositories. The decoupling interface may take the form of a single application programmer interface (API) usable with multiple dynamically linkable libraries.

A Multi-Function peripheral (MFP), a server apparatus, and a client apparatus for generating image output data from document data and transmitting the image output data to the server apparatus are each connected to a network. In the server apparatus, an output data management unit stores the received image output data in an output data storage unit. Upon receiving user authentication information that is input with a user operation on the MFP, the server apparatus determines whether the user authentication information is valid. When the user authentication information is determined to be valid, the server apparatus transmits to the MFP one or more among the stored image output data associated with the user authentication information.
