A New Secure Data Communication Method Using Wavelet Transform

Data communication is part of life now and its security is of utmost importance. Cryptographers provide new methods for security and intruders always want to break them. In modern scenario, the need of the hour is to develop easy to use security methods which can provide high level of security as well. In this paper, a new method of data communication is proposed using the properties of wavelet transform. The embedded data does not create any visible change in the carrier image. A rigorous security analysis is also provided in order to prove that the method is resistive against various security attacks and very efficient for implementation point of view.
