Abstract
A computerized method electronically signs and authenticates documents using cards with associated private keys. A hash of a document is obtained from a user by a cloud point of sale (POS) server and a document signing request to sign the obtained hash with a card is received. The document signing request is received via the presentation of the card. The server causes the obtained hash to be signed using the private key of the card and an associated signature ID is generated. The signed hash and generated signature ID are stored, and the generated signature ID is provided to the user for use in future authentication of the document. Later, a document authentication request is received that includes the generated signature ID and a hash of a target document to be authenticated. The signed hash is decrypted and compared to the hash of the target document to determine its authenticity.
