Image Protection is one of the most important issues that have created problems in technology challenges in the past and present years, whether they are stored or when sent to other parties. And how to develop the techniques adopted in encrypting it, devise new methods, or integrate the available technologies to provide high security in encrypting images or any important data and preserving them from loss or hacking. This paper presents a new method to generate a random keychain using genetic algorithm techniques to develop new generations and XOR technology to encrypt digital images. Where the results showed the high efficiency of the encryption method with its ease of use and the preservation of the original image data after decoding with high accuracy and speed in implementing the strategy used. The efficiency of these switches for use has been tested using the National Institute of Standards and Technology (NIST) and the statistical randomness test, and the tests were successfully passed.

Ease of access to digital images and the many images editing programs available, like photoshop. All this makes the Issue of protecting images against modification becomes essential. Some images contain crucial information that can risk a patient's life, such as medical images and e- government images that relate to citizen information and state or ministry security. The watermark was one of the essential methods for this type of protection, especially the fragile watermark, which is very sensitive to any attack. Because of its other characteristics, it was one of the techniques that proved its efficiency in detecting tampering and the authenticity of images— also, watermarking focuses on protecting the image itself, not about protecting the secret message. A fragile watermark is a watermarking which inserts some information to cover an image to secure it .fragile watermarking could use in such a way and implement in spatial or frequency domain or in both so, making it a hybrid watermarking scheme. The Paper presented set of fragile watermark techniques used by the researchers with the performance metrics of an algorithm used in spatial and frequency domains, also showing how to use artificial intelligence with a watermarking technique to protect Document images from manipulation and forgery.
