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