Abstract

Systems and methods for document control using public key encryption are provided An interface program serves as a software interface between user applications used to create and access documents and a data storage system that stores the documents in an encrypted form When a document is saved, information corresponding to the destruction of that document is obtained The document is encrypted and stored with a pointer to an encryption key on a token/key server When the document is subsequently accessed, the interface program will read the pointer and attempt to retneve the key If the key has expired in accordance with the destruction policy, the document is inaccessible Otherwise, the document is decrypted using the key Multiple documents may be saved according to the same destruction policy and even the same key, thereby greatly enhancing the ability to 'destroy' documents regardless of their location with minimal process
