CONTENT ADDRESSABLE INFORMATION ENCAPSULATION, REPRESENTATION AND TRANSFER

摘要

PROBLEM TO BE SOLVED: To provide a method and a device capable of transferring surely a file by a verifiable method and capable of acquiring the file from a more convenient source in a site for receiving the file. SOLUTION: A process for preparing some assets on a transmission source computer starts with selecting the prepared assets(102). Cipher hash asset identifiers are generated (104). Each of the asset identifiers is computed using a content of the specified asset. An asset list is generated including the asset identifiers computed from the assets (106). A cipher hash asset list identifier is generated computed from the asset list (108). The asset list identifier is stored for reading-out in the later. The selected assets are also stored either locally or on a computer network to be stored safely. COPYRIGHT: (C)2007,JPO&INPIT
