    I've been using this in a Rails app to detect duplicate image uploads for years. It works really well.

  • Legal question – license of software that includes GPL 3.0 software

    I am the current maintainer (albeit, not a great one, but still a maintainer) the phashion ruby gem (https://github.com/westonplatter/phashion).

    I was notified by a user that the current MIT license of phashion may conflict with the GPL 3.0 license of the pHash software included in it. The argument goes that since phashion includes the source code of pHash as apart of its distribution, it needs to also use the GPL 3.0 license.

    My question ... is there a licensing conflict between phashion and pHash? If so, what are the options?

    NOTE - I realize I'm asking a legal/IP question. I will not treat comments or opinions as legal advice.
