SYSTEM AND METHOD FOR ELECTRONIC STORAGE AND RETRIEVAL OF AUTHENTICATED ORIGINAL DOCUMENTS |
摘要 |
Digital signatures are not valid indefinitely but only during the validity periods of their authentication certificates. This poses a problem for electronic information objects that are intended to have legal weight for periods longer than the remaining validity period of a signature. There are thus 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, 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. Another method includes creating an object-inventory from at least one stored original object, including an object identifier and a signature block for each object. A time stamp and a signature and certificate of the trusted custodial utility is applied to the object-inventory. Other methods involve handling information objects that are transferable records according to specified business rules, which avoids that copies of the transferable records can be mistaken for originals.
