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 management infrastructure to collect, process and renew timestamps.
