چکیده

<p class="Abstrak">Kemudahan untuk mengakses dan berbagi media digital saat ini menimbulkan kekhawatiran mengenai pelanggaran hak cipta atau pembajakan. Sehingga perlu memberikan identitas kepada setiap agar tidak mudah dibajak diklaim oleh pihak-pihak yang bertanggung jawab. Salah satu cara pada suatu tanpa mengurangi kualitas dari medianya sendiri yaitu dengan menggunakan watermarking. Pada paper mengusulkan metoda watermarking gabungan <em>Integer Wavelet Transform</em> (IWT) <em>Chinese Remainder Theorem</em> (CRT) menghasilkan visual ketahanan baik beberapa serangan. Hasil penelitian diperoleh nilai-nilai <em>Peak Signal-to-Noise Ratio</em> (PSNR) mendekati 1 <em>Normalized Correlation Coefficient</em> (NCC) sama 0,71337, menunjukkan metode IWT CRT mampu watermarked image <em>imperceptibility</em> terhadap serangan seperti gaussian, salt & pepper kompresi JPEG2000 tetapi tahan rotasi kontras karena nilai NCC dibawah 0,5 </p><p class="Abstrak"><em><strong>Abstract</strong></em></p><p class="Abstract">Today's ease of accessing and sharing raises concerns about copyright infringement or piracy. So it is necessary to give identity each so that not easily hijacked claimed by irresponsible parties. One way a without reducing the quality itself use This proposes method using combination Integer Transform Chinese Theorem produce with good resistance from several attacks. The results obtained Peak Ratio values are close Normalized Coefficient equal 0.71337. shows methods able images imperceptibility provide attacks such as compression but resistant rotation contrast because value below 0.5</p>

Image Steganography Method Using Integer Wavelet Transform

Digital Steganography explains the art and science of writing hidden messages in such a way that, apart from the sender and intended recipient, no one suspects the existence of the message, a form of security through the state of being unknown. The main two famous schemes used for image steganography are spatial domain embedding and transform domain embedding. The main aim of Wavelet Transform ...

Proof. There are three cases: (1) A and B are in the same column. Then, since in each column we picked the shortest student, A is shorter than B. (2) A and B are in the same row. Then, since in each row we picked the tallest student, B is taller than A. (3) A and B are neither in the same row, nor in the same column. Let C be a student who is in the same row as A and in the same column as B. Th...
