Abstract

For a certain reason, usually an agency validates certain document sheets using a printed signature, for example the Dukcapil Office in signing a family card. The printed signature here uses a Qr-Code or barcode instead of a wet signature. Verification of the printed signature is done by scanning a Qr-Code or barcode which triggers the appearance of a website page stating the validity of the printed signature. One of the disadvantages of printed signatures is that they are vulnerable to tampering, such as transferring signatures for unauthorized documents. This is because the signature authenticity validation authority is single. This article introduces a blockchain-based signature protocol that is believed to be able to guarantee the security of printed signatures and the document itself. The security guarantee here is because the validation authority holder is not single but is distributed among the various parties involved.
