A novel approach for simultaneous compression and encryption of image in wireless media sensor network

In this paper, a Discrete cosine and Discrete Wavelet transform based algorithm for simultaneous image compression and encryption is proposed, which is useful for reliable data transmission. The Secure Force encryption algorithm used is pertinent to wireless sensor networks (WSN). The efficacy of our proposed algorithm is evaluated on the basis of the PSNR (Peak Signal to Noise Ratio), MSE (Mean Square Error), computing time and percentage compression. The proposed algorithm helps in reducing data redundancy significantly which makes it energy efficient while considering it´s utilization for WSN.
