According to the format and process of compression and decompression of JPEG files,an algorithm toencode JPEG files with chaos sequence is proposed based on logistic mapping.By using APP3 identifier to denotethe encrypting algorithm,the experiments for the encryption and decryption are conducted.The results show thatthis algorithm is effective.
