e-Certificate system based on Portable Document Format and QR Code for Academic Activities

Many academic activities are held in an educational institution. This activity is to increase knowledge beyond what is obtained during classroom learning. Participation is always proven by the existence of a certificate. Issuance of certificates costs money for paper, printing and distribution. The emergence of the paperless era should be able to change the existence of certificates. Paperless can be done with the presence of digital documents that can be accessed independently (portable), easily and across platforms. Another issue is how this portable certificate document is also protected from the problem of unauthorized transmission or reproduction. For this, it is necessary to develop a good application to facilitate the existence of a secure e-certificate, and a solution related to the authenticity of the certificate produced.
