    Abstract
    This thesis aims to discuss how to determine the originality of digital image of an ownership claim by the irresponsible party. It can be carried out by applying the watermarking process by using Information Dispersal Algorithm (IDA). The watermarking process can be done throught the decoding and encoding process by using Huffman algorithm, to keep the confidentiality of the generating parameter. To prove the confidentiality of a watermarked digital image, the detection and extraction process are applied to the watermarked digital image which has the similar size with the original one, or to the watermarked digital image which has been re-sized.
     
    Tesis ini memaparkan bagaimana menunjukkan keaslian citra digital dari tindakan klaim kepemilikan citra digital oleh pihak yang tidak bertanggung jawab. Hal tersebut dapat dilakukan dengan proses watermaking menggunakan Information Dispersal Algorithm (IDA). Untuk menjaga kerahasiaan parameter pembangkit proses watermarking dapat dilakukan dengan proses encoding dan decoding dengan algoritma Huffman. Pembuktian keaslian citra digital ter-watermark dilakukan dengan proses deteksi dan ekstraksi watermark pada citra digital ter-watermark yang memiliki ukuran yang sama dengan citra digital asli, maupun yang telah mengalami perubahan ukuran.
