Kertas kerja ini adalah untuk mencadangkan penanda air digital untuk melindungi pemilikan kandungan video yang dimampatkan oleh profil utama H.264/AVC. Skim ini bercadang untuk dilakukan semasa proses CABAC (Pengekodan Aritmetik Binari Adaptif Berasaskan Konteks) yang merupakan pengekodan entropi profil utama. Ia menggunakan konteks yang diekstrak semasa proses pemodelan konteks CABAC untuk meletakkan bit tera air dengan hanya menyemak nilai konteks dan menentukan pekali. Proses penanda air juga semudah menggantikan bit tera air dengan LSB (Bit Kurang Ketara) bagi pekali yang sepadan untuk ditanda air. Keputusan eksperimen daripada menggunakan skema ini dan menyerang dalam pelbagai cara seperti pengaburan, penajaman, pemangkasan, penambahan hingar Gaussian dan pengubahsuaian geometri menunjukkan bahawa tera air yang dibenamkan oleh skema ini mempunyai ketidakjelasan dan keteguhan yang sangat tinggi terhadap serangan. Oleh itu, kami menjangkakan ia dapat digunakan sebagai skim penanda air yang baik, terutamanya di kawasan yang penanda air perlu dilakukan semasa proses pemampatan dengan memerlukan jumlah proses yang minimum untuk penanda air.

Abstract: This paper is to propose a digital watermarking to protect the ownership of a video content which is compressed by H.264/AVC main profile. This scheme intends to be performed during the CABAC (Context-based Adaptive Binary Arithmetic Coding) process which is the entropy coding of the main profile. It uses the contexts extracted during the context modeling process of CABAC to position the watermark bits by simply checking the context values and determining the coefficients. The watermarking process is also as simple as replacing the watermark bit with the LSB (Least Significant Bit) of the corresponding coefficient to be watermarked. Experimental results from applying this scheme and attacking in various ways such as blurring, sharpening, cropping, Gaussian noise addition, and geometrical modification showed that the watermark embedded by this scheme has very high imperceptibility and robustness to the attacks. Thus, we expect it to be used as a good watermarking scheme, especially in the area that the watermarking should be performed during the compression process with requiring minimal amount of process for watermarking.
