METHOD FOR ELECTRONIC STORAGE AND RETRIEVAL OF AUTHENTICATED ORIGINAL DOCUMENTS

摘要

There are provided methods of handling stored electronic original objects that have been created by signing information objects by respective transfer agents, submitting signed information objects to a trusted custodial utility, validating the submitted signed information objects by at least testing the integrity of the contents of each signed information object and the validity of the signature of the respective transfer agent, and applying to each validated information object a date-time stamp and a digital signature and authentication certificate of the trusted custodial utility. One method includes re-validating an electronic original object by verifying the digital signature of the trusted custodial utility applied to the object and applying to the re-validated object a current date-time stamp and a digital signature and current authentication certificate of the trusted custodial utility. Other methods involve handling information objects that are transferable records according to specified business rules, which avoids problems that can arise if copies of the transferable records can be mistaken for originals.
