“…by using image pixels to conceal watermarking message bits and using Least Significant Bit (LSB) technology to replace the original image bit with one of the watermark bits [11]. J. Abd-Alhameed, and A. Ahmad [12] Suggested inserting fragile and robust watermarks were in method, each specified clearly. The images divide via three different channels Red Green Blue (RGB) and employ a green channel.…”

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. Index Terms— fragile watermark, spatial domain, frequncy domain
