The principle and features of Arnold transform is introduced, and the period become the encryption key and decryption key. The LSB method is introduced too. An improved LSB algorithm and Arnold transform can make the embedded information anti-shear and anti-extract protection. Experiments show that the method is suitable for grayscale and color images. It is effective to protect information, and easy to implement.
