Background

Image Similarity Checker helps companies review generated images by finding similar material on the web. Hakuhodo developed the tool for use within its group before offering it to client businesses. It compares images using several approaches and presents scores intended to help reviewers assess similarities. The tool can also generate search terms from image features to assist the search. [Hakuhodo product announcement](https://www.Hakuhodo.co.jp/news/newsrelease/267420/).

The business version includes authentication, audit logs and reports. Those functions let a company keep a record of who checked an image and the result of that check. Hakuhodo explicitly limits the tool’s role to supporting comparison: a similarity result is not a determination of copyright infringement. The client remains responsible for the final rights decision.
