Sistem Ijazah Digital dengan Layanan Keamanan Perlindungan Hak Cipta Menggunakan Watermark dan Digital Signature
Abstract
The vulnerability of digital files against unauthorized use of copyright such as duplication, distribution, and modification of digital files illegally causing its validity is not guaranteed. Research is underway to design a security system granting copyright protection in the digital diploma file to accommodate the digital diploma proving the validity of the file. Security system in this study applies watermarking and digital signature techniques. DCT and PVMA algorithm is used to process watermarking and Tiger Hash and RSA algorithms to obtain a digital signature. The study focused on the digital signature of subsystems as well as system integrity. Security services provided data integrity and authentication with the marking. This security system has been implemented on a web-based client server system.
