![]() DigiStamp software calculates a hash for the data file. The timestamp is by virtue of the third party receiving a copy of the document, receipt and transmittal.ĭigiStamp's technique keeps your document in your computer, thus your data remains confidential with no chance of intercept. Commonly this technique includes retrieval of the document by a third party to achieve a level of delivery confirmation. With this technique the user's data file is sent to a third party, most probably over the Internet. To verify a DigiStamp e-TimeStamp, all that is needed is the root key of DigiStamp, which is available to anyone at any time and widely distributed. In order to verify a timestamp created with hash chaining, the service provider must be contacted by the customer after the additional protection is applied.Īs of 2014 DigiStamp uses hash chaining to further protect our customers, but DigiStamp's primary technique uses public-private key encryption. ![]() At given intervals, the current value of the super hash is further protected to avoid later tampering, publication is a strong technique. The succession of hashes is kept as a sequential record of all hashes created by the service provider. ![]() This technique combines the hash of one user's file with the hash of other user's files. All techniques assume the data is in a digital format and the end-user wants to automate the timestamping process in lieu of a manual notarization technique. We compare our timestamp standard with several other techniques. ![]()
