Accordingly, the issue of copyright infringement that may occur in the PC video happening in the smartphone image. In this paper, we propose the insertion of the watermark for copyright protection of a mobile smart phone display image. A watermark embedding algorithm based on the discrete wavelet transform in the frequency domain for the mobile device were selected for watermarking. Using the Matlab as a tool to test a discrete wavelet transformation is implemented a structure of a watermarking. Additional research is needed to watermarking for mobile is much less if you apply the smartphone market is growing increasingly watermarking techniques in the mobile environment in the modern society.
