TinEye [Reverse Image Search Engine]

Dfg

TinEye is a reverse image search engine that is very easy to use. You can submit an image to TinEye to find out where it came from, how it is being used, if modified versions of the image exist, or to find higher resolution versions. TinEye is the first image search engine on the web to use image identification technology rather than keywords, metadata or watermarks. When you submit an image to be searched, TinEye creates a unique and compact digital signature or ‘fingerprint’ for it, then compares this fingerprint to every other image in TinEye’s index to retrieve matches. TinEye can even find a partial fingerprint match.


Images uploaded to TinEye are not added to the search index, nor are they made accessible by other users. Copyright for all images submitted to TinEye remains with the original owner/author. Search images submitted by unregistered users are automatically discarded after 72 hours. Links to these searches will stop working after 72 hours, unless a registered user happens to save the same image.

I don't know if someone might find this helpful but in my books this is pretty awesome utility. Just upload the images and let it do the work.

How does TinEye work?

When you submit an image to be searched, TinEye creates a unique and compact digital signature or 'fingerprint' for it, then compares this fingerprint to every other image in our index to retrieve matches. TinEye can even find a partial fingerprint match.

TinEye does not typically find similar images (i.e. a different image with the same subject matter); it finds exact matches including those that have been cropped, edited or resized.

Also, try plugin as well.
