What is time stamp?
Digital Time stamping 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 time stamper’s integrity is never compromised. eMudhra timestamp authority achieves this by cryptographically binding the data’s unique hash (typically a SHA-1/2 hash value) with the current date and time that is synchronised with the trusted time source.
