METHOD AND MECHANISM FOR INTENSIFYING TIME LIMIT MANAGEMENT

摘要

PROBLEM TO BE SOLVED: To reduce the delay of electronic transmission and to impart fast feedback to a presenter by comparing evidence stored in a directory with a complete presented document and returning 2nd presentation rejection display to a presentation program when their coincidence is not obtained. SOLUTION: Information is collected by a presentation requirement center 12 when a presentation processor 10 generates a new requirement set and transmits the set to the center 12. A gateway finds a newly presented document, when evidence does not exist, the presented document is rejected and when evidence exists, the gateway decodes stored evidence and verifies the digital signature of a presenter in order to prove that the original presented document arrives from an expected presenter. The gateway once confirms the identification of the presenter and confirms a complete presented document corresponds to the presented document that becomes the base of evidence. When two compared digests are not matched with each other, the presented document is rejected.
