Digital Image Watermarking using Tenth Root of Exponential Function

In this paper, digital image watermarking using tenth root of exponential transformation has been introduced in the frequency domain. In the proposed technique, the secrete image is first encrypted and compressed using exponential function and then embedded into the host image. The resultant images obtained from the proposed algorithm is subjected for various security attacks and the results are compared with the other existing algorithms. The results obtained are better compared to the existing techniques.
