Timestamping Techniques

Timestamping techniques are methods used to record the exact date and time when digital data or transactions occur, ensuring their authenticity and order. Common methods include attaching a digital timestamp using secure cryptographic methods, or using a trusted third-party service called a timestamp authority to verify when a document or transaction was created or altered. These techniques help prevent disputes, fraud, or tampering by providing a reliable, verifiable record of when events happened, much like a digital equivalent of a notarized date on a document.
