Startup Idea: Image Duplication Detection Software for Legal Industry

Startup idea to develop a software tool that assists in the identification and deduction of identical photographs, despite differing names, to eliminate redundancy in the legal industry. The software should compare either image metadata or the image content itself to discern identical photos.

I work in the legal industry and often work with numerous photographs that are produced by the opposing party in a lawsuit.

I would like a way to compare and see if two photographs are identical, despite the fact that they have different names. Yes, I would pay for this.

Or, presumably, my firm would, as de-duping can be a considerable expense. The software would help de-duplicate produced documents.

It could, potentially, compare metadata, or the image itself, to see if one photo is an exact duplicate of another. Thank you!
