Abstract -
Existing techniques when utilize compression there is no thought of security, correspondingly when it portray encryption there is no thought of size i.e. compression.There are two methodologies CE i.e.compressiontook after encryption and EC i.e. encryption took aftercompression. In our task, our succession will be EC i.e. image encryption is performed first then the image compression is connected. For image encryption we will utilize slope figure. Correspondingly for compression we will utilize Discrete Cosine Transform. In the proposed approach, we are not utilizing CE in light of the fact that an interloper has less intimation to get to image yet encryption might again build the size. To spare the transfer speed fractional encryption is done in light of the fact that image transmission is required two times. Firstly, when quarter image is send and furthermore when entire packed image is send.
