Forgery detection in images with Walsh-Hadamard transform for scientific crime detection

In addition to speeding up affairs, digital developments also bring risks and new crimes emerge, and maintaining the confidentiality of images is important for people and security organizations, and new technologies based on artificial intelligence are needed to discover He used the science of crimes. There are different images in the country that are owned by people or organizations, and any manipulation or forgery needs to be recognized scientifically. In this article, with the help of presenting a scientific method based on machine vision, it has been tried to improve the security of surveillance camera images while moving on the Internet platform, and while discovering any possible forgery and manipulation of images, they have been reconstructed with the help of digital watermarking.

In this article, according to the application of digital watermarking of images with the help of Walsh-Hadamard transformation, it was found that possible forgery and possible manipulations in sensitive images can be discovered to a large extent and compared to its reconstruction by the presented method. took action The laboratory results of the proposed method are very satisfactory and reliable.
