An e-signature confirms the authenticity and integrity of a transaction or other security-critical communication.
It's a short piece of information used to authenticate a message and is based on a MAC algorithm (Message Authentication Code).
VASCO's e-signature solution works by creating an e-signature unique to each particular transaction or document using such data as account numbers, transaction amounts and timestamp. Based on MAC technology, this solution preserves data integrity and ensures authenticity, rendering any changes made to a transaction or document after it has been electronically signed, invalid.
The signing person can verify the transaction data which need to be signed before confirming a transaction, thanks to the "What You See Is What You Sign" (WYSIWYS) functionality. With WYSIWYS the transaction data are displayed on the DIGIPASS screen.
