Document verification using quick response code with modified secure hash algorithm-1 and modified blowfish algorithm

A previous study has been conducted integrating modification on secure hash algorithm 1 (SHA-1) to document integrity verification of printed documents using quick response (QR) codes. However, encryption is warranted as data transmitted in plaintext directly the server prevent hacking and ensuring not only but security well. more secured QR code was designed developed by successfully incorporating a better hashing algorithm– modified SHA-1 modern algorithm–modified blowfish algorithm. By both, confidentiality assured compared research. The software checked against user requirements check acceptability software. Error rate accuracy were also see how performed. Based testing conducted, it found that with integration Modified Blowfish acceptable, accurate, secure.
