In order to renew the image that is attacked by shear transformation,an digital image encryption algorithm was proposed based on chaotic sequences.This approach encryption digital image by permuting on bitmap after pretreatment,and decryption pixels’ values by using neighboring pixels’ values,it can protect the encryption image from shear transformation attack.The experimental results indicate the algorithm has a good efficiency and is safer.
