Abstract: With the tremendous rise of information exchange via internet transmission, image security is becoming an important issue that we need to deal with. As, images are being recycled more in business and industrial process, military and medical and also in scientific researches, it is really an important issue to shelter the personal image statistics from unwanted admission or hackers. Because of improvement of technology, the attacking techniques, and hackers are also becoming more and more intelligent. Therefore, traditional techniques of image encryption are not up to the level to compete with the attackers. Image encryption has been a huge area of research study. The protection of image data is very important because it contains actual features and figures of a person or anything. Image encryption is used to secure an image from unauthorized access and increase image security in the internet. Nowadays Internet is used for transferring and loading huge amount of image data. Since the internet has many loopholes and several scopes of hacking or being attacked by unauthorized persons, our personal and confidential image need to be protected during transmission over internet. Researches did satisfactory amount of researches and invented variety of image encryption algorithms. But still there is need of improvement of the image encryption techniques to make it more secure. In this paper, we proposed an advanced double domain encryption technique that encrypts the image two times. First in frequency domain and secondly in spatial domain by using DCT (Discrete Cosine Transform) encryption and compression technique.

Keywords: image, security, encryption, internet.
