The authenticityand integrityof documents areessentialindata exchange and communication. Digital documents must be verifiable for their authenticity and integrityby all parties that use the documents. Generally, digital documents can be authenticated by using digital signatures. This study aims to implement adocument authentication system based on Quick Response(QR) code and digital signature. As the case study, thedocument authentication system is implementedto generate digital signatures forstudent’scertificate documents. Furthermore, the system can also verifythe authenticityof the certificate documents. Creatinga digital signature requires ahash function algorithm forgeneratingthe message digestof the document. In addition, an algorithm togeneratethe public key and the private key used in the encryption/decryption of the message digest is also needed. Thehashfunction utilizedin this study is the Secure Hash Algorithm-256 (SHA-256), while the algorithm used for encryption/decryption is theRivest-Shamir-Adleman (RSA)algorithm. The system is evaluated by verifying 30 student certificate documents, of which 15of them were certificates with QR code signature generated by the system and the other 15were certificates with QR code signature generated usinga random QR code generator. The system’stesting results demonstrate thatthe systemcan ensurethe authenticityand integrityof the signed certificate documents toprevent document falsification. All documents that contain random QR codes were correctly identified asfalse documents
