In this paper new partial encryption schemes are present, in which a secure encryption algorithm is used to encrypt only part of the images. Only part of the original data is encrypted for two different grayscale images and two color images of size (256 × 256) pixels, resulting in a significant reduction in encryption and decryption time.
