digital Signal and Image Processing Using MATLAB The most important theoretical aspects of image and signal processing (ISP) for both deterministic and random signals are covered in this guide to using MATLAB® . The discussion is also supported by exercises and computer simulations relating to real applications such as speech processing and fetal-heart–rhythm tracking, and more than 200 programs and functions for numerical experiments are provided with commentary.

digital Signature Algorithm (DSA)是Schnorr和ElGamal簽名算法的變種，被美國NIST作為DSS(digitalSignature Standard)。算法中應用了下述參數(shù)： p：L bits長的素數(shù)。L是64的倍數(shù)，范圍是512到1024； q：p - 1的160bits的素因子； g：g = h^((p-1)/q) mod p，h滿足h < p - 1, h^((p-1)/q) mod p > 1； x：x < q，x為私鑰 ； y：y = g^x mod p ，( p, q, g, y )為公鑰； H( x )：One-Way Hash函數(shù)。DSS中選用SHA( Secure Hash Algorithm )。 p, q, g可由一組用戶共享，但在實際應用中，使用公共模數(shù)可能會帶來一定的威脅。簽名及驗證協(xié)議如下： 1. P產生隨機數(shù)k，k < q； 2. P計算 r = ( g^k mod p ) mod q s = ( k^(-1) (H(m) + xr)) mod q 簽名結果是( m, r, s )。 3. 驗證時計算 w = s^(-1)mod q u1 = ( H( m ) * w ) mod q u2 = ( r * w ) mod q v = (( g^u1 * y^u2 ) mod p ) mod q 若v = r，則認為簽名有效。 DSA是基于整數(shù)有限域離散對數(shù)難題的，其安全性與RSA相比差不多。DSA的一個重要特點是兩個素數(shù)公開，這樣，當使用別人的p和q時，即使不知道私鑰，你也能確認它們是否是隨機產生的，還是作了手腳。RSA算法卻作不到。

This discussion will attempt to outline some truths and common misconceptions about digital audio watermarking. It will survey the intrinsic obstacles that such technology is required to overcome, shedding light on its performance criteria, compromises and limitations. While doing so, it will also survey a few common types of applications, hopefully leading to a clear understanding as to the appropriateness of such technology and its expertise within multimedia content protection.
