Cryptographic time stamping
WebVerification of the time-stamp integrity The cryptographic integrity of the time-stamp, for example the ASN.1 structure is correct, and the datum (the data that have been time-stamped) belong to the application. It can be verified through the CERTSIGN TSA’s web service form CERTSIGN, offered free of charge. 6.2.7 Applicable law Trusted timestamping is the process of securely keeping track of the creation and modification time of a document. Security here means that no one—not even the owner of the document—should be able to change it once it has been recorded provided that the timestamper's integrity is never compromised. The administrative aspect involves setting up a publicly available, trusted timestamp manageme…
