In the real time scenario, image encryption has been carried out early to the compression for maintaining the safety of the image. In this paper, a highly efficient image Encryption-Then-Compression (ETC) system has been designed, where the lossless compression is taken into account. The proposed image encryption method is operated with image encryption AES and RSA algorithm with Set Partition in Hierarchical tree(SPIHT) which shows logically high security compression technique. The ETC method  is proved  to be more simpler and efficient method while analyzing the parameters like Compression Ratio (CR), Peak Signal to Noise Ratio (PSNR).
