In latest years, there is a speedy development in the multimedia and network technologies in computer era. Transmission of multimedia information over the network leads the major problems of security, privacy and data size. Images are widely used and the major problems are how to protect the images and also reduce size of the image in order to maximize the network utilization. Various techniques are there with a view to secure the image and to reduce the size of the image. Security and privateness aren’t taken into consideration in the sooner Image compression techniques. To provide the privacy and security, the encryption is applied as well as compression reduces the data size. So that, to overcome the issues in multimedia and network technologies, compression is combined with encryption. In order to get higher network utilization, the encrypted images are compressed. An efficient image Encryption Then Compression (ETC) system is designed. In proposed scheme Advanced Encryption Standard algorithm is used to encrypt the image with the intention to get high security.
