Hakuhodo launches Image Similarity Checker for clients

The Image Similarity Checker had until now been an internal tool within Hakuhodo DY Group, so the October 19 launch marks its first availability to outside client companies. That shift required adding enterprise-grade governance: single sign-on authentication and audit logs that record who checked which image and what the result was. The tool is positioned for advertising creative production that uses generative AI, where confirming copyright risk is part of the workflow.

Beyond simply finding similar images on the web, the tool scores similarity across multiple perspectives and presents results in a list. Hakuhodo says this makes the confirmation work more efficient and helps visualize and record the judgment process. It also uses generative AI to analyze image features and generate related keywords automatically, which it says enables high-accuracy search.

The combination of scoring and logging appears intended to support corporate AI governance and audit responses, not just one-off checks. Hakuhodo also notes that similarity is judged by multiple algorithms. For client companies, the value may lie as much in the documented record of checks as in the detection itself.
