| Abstract | ||
| Many digital services require reliable security in storage and transmission of digital images. Due to the rapid growth of the internet in the digital world today, the security of digital images has become more important and attracted much attention. The prevalence of multimedia technology in our society has promoted digital images to play a more significant role than the traditional texts, which demand serious protection of users' privacy for all applications. Encryption techniques of digital images are very important and should be used to frustrate unauthorized access from opponents. In this paper a new approach is proposed for partial encryption in digital image based on dragging the longest wavelength color in digital image then input the extract color to the plasma encoding algorithm to have partial ciphered image that can be deciphered at the recipient side using the proposed retrieve algorithm. It is possible to apply multilevel for the proposed approach to increase the security level with less time for encryption/decryption. The new approach test appeared that the encryption/decryption processes was very flexible and efficient. | ||
