TinEye is an image search engine by Idée that lets you find where a particular image has been used on the web.
You are probably saying, “Oh, but there is Google image search for me. Why would I need another one?”. But TinEye is an entirely different kind of image search. While Google image search uses text to search for associated images, TinEye uses an image as a query for searching. Google can’t do that - at least, not yet.
If you’re in a hurry, here’s a quick video explanation from Idée on how TinEye works. Or read on for my explanation.
To search using TinEye, you can either enter a URL to a image on the web or upload an image from your computer. Another way is to install the TinEye browser plugin for Firefox or Internet Explorer. With the plugin installed, you can right click on any web image to search for it using TinEye.
Just like Google indexes all the web pages it crawls, TinEye creates a digital signature or ‘fingerprint’ of the images using sophisticated pattern recognition algorithms. Once you query using an image, TinEye instantly analyzes and compares the ‘fingerprint’ of your query image with the images in its search index.
TinEye not only finds identical images but also the modified versions of the image. As long as the images are alterations of the same query image, TinEye can find them and include them in your search results. But, do remember that TinEye does not actually ’see’ the image, in the sense that if you upload the image of a dog, it does not see it as a ‘dog’ and fetches you images of other dogs. It only finds if the same image has been used, even if altered or modified. TinEye orders the results by most similarities, meaning that altered images are found towards the end of the search.
So if you take the example of the Mona Lisa :

TinEye will return results such as these :

Now that we have seen what TinEye can do, let’s see what you can do with TinEye. Here are some of the possible uses of TinEye.
I am sure you can think of even more uses for TinEye. If you do, please put your ideas in the comments.
As of writing this post, TinEye has over 586 million images indexed, which is actually a small number considering the size of the web. But TinEye crawls new images on the web on a regular basis and the number of indexed images is constantly growing. So this is gearing up to be an amazing website and you have to wonder when Google will have technology like this?
TinEye is currently in private beta but the company has generously given Make Use Of 1000 pre-approved invites to give away to our readers! They’ve told us you just have to click on this link and you should be on your way to getting set up! Then come back and let us know in the comments what you think!

as tiny states, their search index is still “tiny”, besides the mona lisa listed here, I couldn’t find any photos listed elsewhere…
I ran photo searches and it brought back similarities. So it does work. OK it’s not perfect but that’s because it’s a beta service. But it does work and it’s definately something to watch in the future.
Is it just me or is that woman in the video really attractive? What happens if we put her picture into the search engine??
Yes she’s very attractive - that’s why she’s in the video!
I can haz beta?
Have you lost the power of speech Karl? I know the woman is attractive but come on!
If you want a beta account, the link is in the last paragraph of the article.
For some reason the bottom of the post did not come through in my reader! Let’s hope I am not to late…
@Aibek - LMFAO!!

I think it is a very neat idea, but there is of course the spooky point that someone, who has a photo of someone, they could use this to find out who that person is, and possibly even find some embarrassing photos of you…
