The temporal correlation between consecutive frames is exploited. The proposed algorithm is based on video compression-encryption using 3 Dimensional (3-D) discrete fractional transforms, which makes full use of the additional degree of freedom provided by the fractional orders to achieve an optimum domain in the compression and encryption. We first used Discrete Fractional Fourier Transform (DFrFT) to compress the adjacent difference frame of video and thereafter the obtained compressed difference frame was encrypted using Discrete Fractional cosine Transform (DFrCT) with fractional keys. The worth of the reconstructed video was measured with Mean Square Error (MSE) and Peak Signal to Noise Ratio (PSNR). Noteworthy improvement in results using our method from that of current existing methods is the efficacy of this study.
