      "abstract": "Penelitian ini mengimplementasikan sistem invisible watermarking hibrida \r\nmenggunakan metode Least Significant Bit (LSB), Canny Edge Detection, dan\r\nArnold Cat Map (ACM) untuk perlindungan hak cipta citra digital. Penggunaan\r\ndeteksi tepi bertujuan meningkatkan imperseptibilitas dengan menyisipkan data\r\nhanya pada area bertekstur kompleks yang kurang sensitif bagi penglihatan\r\nmanusia. Sebelum disisipkan, watermark diacak menggunakan ACM untuk\r\nmenjamin keamanan data. Sistem berbasis web ini diuji pada citra standar (Lena,\r\nBaboon, Peppers) dan menghasilkan nilai rata-rata PSNR sebesar 69,33 dB, jauh\r\nmelampaui standar kualitas 40 dB. Uji keamanan membuktikan watermark hanya\r\ndapat diekstraksi jika kunci (P, Q, N) tepat. Meskipun unggul dalam kualitas\r\nvisual dan kerahasiaan, sistem ini bersifat fragile terhadap kompresi JPEG dan\r\nmanipulasi geometri.",
