Forgery of important paper-based documents such as diplomas, certificates and other legal documents is more and more serious and sophisticated. For the purposes of fraud, appropriation of property, job application assignment and authority swindle, this has led to material loss, belief deterioration as well as social instability. This paper proposes a feasible solution to the forgery of paper-based diplomas, certificates and legal documents. With the application of QR bidirectional barcode and digital signatures and the usage of RSA algorithm, this proposed solution makes encryption, decryption and verification of information in a text on smart phones and barcode readers done correctly, safely and quickly.
