The Text Encryption Based on Wavelet Analysis Theory
LI Xiao-yi · Journal of Handan College · 2010
This paper proposes a simple method which uses the relevant knowledge of wavelet analysis and watermark technology to hide the encrypted text message in the corresponding information.Wavelet analysis which develops rapidly in the current mathematics is the development and extension of Fourier analysis' method.It breaks through the limit in time and frequency domain of the Fourier analysis.In this paper,we describe the basic theory of watermark technology,and then give a simple introduction about Matlab toolbox.The procession of encrypting and decrypting of text or number which is converted by turn5 software is more detailed.
