Microsoft has somewhat similar technology called PhotoDNA. How does PhotoDNA work? PhotoDNA technology converts images into a common black-and-white format and uniform size, then divides the image into squares and assigns a numerical value that represents the unique shading found within each square. Together, those numerical values represent the "PhotoDNA signature" or "hash" of an image, which can then be compared against signatures of other images. While the technology cannot be used to identify a person or object in an image, nor can it be used to recreate an image, it can be used to find copies of a given image with incredible accuracy and at scale across the 1.8 billion images shared online every day, even when the images themselves have been altered. https://www.microsoft.com/en-us/PhotoDNA/FAQ?3158ae95-fce7-480c-98aa-d3e75c620697=True https://www.microsoft.com/en-us/PhotoDNA/FAQ?3158ae95-fce7-4...
