Our website provides a free download of Verify 1.0 for Mac. The application belongs to Audio & Video Tools. This free software for Mac OS X is a product of Chris Karr.
From the developer:
Verify checks files and folders containing media files and whether these media files "check out" according to the Creative Commons licensing metadata standard. This application works by scanning these media files for the appropriate data in the Copyright field (MP3, ID3v2 only), looking up the SHA hash online, and comparing the online hash to the local file's hash.
You may want to check out more Mac applications, such as eMail Verifier, Email Verifier or Email Verifier for Mac, which might be similar to Verify.
