Video compression and security both need to be emphasized for reliable and fast communication. This paper proposes an algorithm which emphasize both compression and security through the combination of Embedded Zero Wavelet (EZW) and chaotic logistic map. In the first phase, video is encoded using decoupled 3D-DWT architecture and then compressed using EZW. The data obtained from EZW is given as input to the chaotic logistic map, which provides security. Chaotic logic map is used for providing security as it is simple and more sensitive towards the changes in the initial conditions. The time taken to provide security is efficiently reduced by chaotic logistic map algorithm. To provide a reliable security two keys are used at the transmitter and three keys are used at the receiver. The timing requirement of the chaotic logistic map algorithm is compared with the AES in the results section and found to be much better.
