Transmitted images may have many different applications like commercial, military, medical etc. To protect the information from unauthorized access secure image transfer is required and this can be achieved by image data encryption. But the encryption of whole image is time consuming. This paper proposed a selective encryption techniques using spatial or DCT domain. The result of the several experimental, statistical analysis and sensitivity test shows that the proposed image encryption scheme provides an efficient and secure way for real-time image encryption and transmission. A chaotic logistic map is used to perform different encryption/decryption operation in this proposed method.
