Customize Template Design And Verify Quick Response Code For Issuing E-Certificate

During the past Covid pandemic, the limitations of meetings or direct contact with many people made webinars a solution to keep conveying information to seminar participants. In the webinar, participants came and took part in the event online. This webinar format is often used in seminars, discussions, workshops, and talk shows. Almost all webinars provided electronic certificates (e-certificates) for participants, speakers, and organizers. E-certificates in the form of files and transmitted via the Internet make them vulnerable to counterfeiting; therefore, there needs to be an effort to secure the original data from the certificate owner and the activity data that issued the certificate. To maintain this aspect of data and information security, cryptography provides digital signature facilities that can guarantee authentication, data integrity, and nonrepudiation to eliminate fears of counterfeit certificates. The research system was developed using the RAD method, which is a systematic and sequential approach. In this application, users can design their own certificate templates to be provided to the participants. In addition to certificate design, the user can choose the logo position and signature location. Applications resulting from this research can also verify authenticity using Quick Response (QR) codes.
