menggunakan metode Least Significant Bit (LSB), Canny Edge Detection, dan&#13;
Arnold Cat Map (ACM) untuk perlindungan hak cipta citra digital. Penggunaan&#13;
deteksi tepi bertujuan meningkatkan imperseptibilitas dengan menyisipkan data&#13;
hanya pada area bertekstur kompleks yang kurang sensitif bagi penglihatan&#13;
manusia. Sebelum disisipkan, watermark diacak menggunakan ACM untuk&#13;
menjamin keamanan data. Sistem berbasis web ini diuji pada citra standar (Lena,&#13;
Baboon, Peppers) dan menghasilkan nilai rata-rata PSNR sebesar 69,33 dB, jauh&#13;
melampaui standar kualitas 40 dB. Uji keamanan membuktikan watermark hanya&#13;
dapat diekstraksi jika kunci (P, Q, N) tepat. Meskipun unggul dalam kualitas&#13;
visual dan kerahasiaan, sistem ini bersifat fragile terhadap kompresi JPEG dan&#13;
manipulasi geometri.</mods:abstract><mods:classification authority="lcc">000 Ilmu komputer, informasi dan pekerjaan umum</mods:classification><mods:classification authority="lcc">005 Pemrograman komputer, program dan data</mods:classification><mods:originInfo><mods:dateIssued encoding="iso8061">2026-03-02</mods:dateIssued></mods:originInfo><mods:originInfo><mods:publisher>Universitas AMIKOM Yogyakarta;Fakultas Ilmu Komputer</mods:publisher></mods:originInfo><mods:genre>Thesis</mods:genre></mets:xmlData></mets:mdWrap></mets:dmdSec><mets:amdSec ID="TMD_eprint_31872"><mets:rightsMD ID="rights_eprint_31872_mods"><mets:mdWrap MDTYPE="MODS"><mets:xmlData><mods:useAndReproduction>
