PimEyes - more than a reverse image search

Have you ever experienced a situation where you didn’t know or couldn’t recall the name of something you had in front of you and you really needed to name it? Or a person or a piece of art you had just seen on some commercial and now they are like a visual earworm - you can’t get rid of them. Usually, in this case, you try to google that thing or person by entering their description, features, or some other information. But you may not be aware that if you can see and take a picture of them, there is a much easier way of finding their names. It is called a reverse image search and it allows you to perform a search using only a photo.

 

In PimEyes we use a reverse image search mechanism improved by facial recognition technology to allow you not only to find the same picture but also track down a given face on different photos. How is it possible? Find out from this article. 

What is a reverse image search?

Briefly speaking, a reverse image search is the technology used to search a database using an image. Usually we identify this database with the Internet because it is the biggest and most popular database in the world. However, a reverse image search mechanism can also be used on custom datasets. 

 

The most important part of this technology is the fact that a search is performed based on an image. It’s a reverse situation in regards to what we are used to. Instead of typing a query like “actor from Matrix”, you can take a picture of a poster with him and upload it to the search engine. From the results you can learn that this actor’s name is Keanu Reeves, you also receive a list of other movies where he appears, his biography, and news about him. Usually, this type of search shortens the time spent on looking for the answer by providing a more precise query or at least a useful hint to help perform a regular search. 

 

A reverse image search mechanism can be used for different purposes. There are 4 main usages of this technology:

  • finding the names of things, people, places, etc. (like in the example with Keanu Reeves)
  • finding similar photos or objects from these photos (e.g. another piece of art painted by some artist)
  • finding the same photos (e.g. to verify if someone hasn’t been using them without consent)
  • finding smaller or bigger versions of photos.

Use reverse image search when you have only a photo of the thing or person

What is a face recognition search engine?

Generally speaking, a face recognition search engine is a tool used to search a database for faces. It is a combination of 4 technologies

  1. Reverse image search (understood as the possibility to upload and search by an image)
  2. Recognizing faces by their specific parameters
  3. Comparing these parameters with the ones from a database
  4. Displaying the matching results in a user-friendly, understandable way. 

 

Like in a reverse image search, we usually understand “database” as the Internet, but it can also be custom datasets. 

 

What constitutes a face recognition search engine is that it focuses on faces. This feature allows finding a given face on completely different photos because its measurements are the only parameters that are used to compare the pictures. That is why the background, buildings, other people, or even a different haircut are irrelevant for a face recognition search engine.

In what situations is a face recognition search engine the right tool to use?

Face recognition search engine technology can be widely used, but there are 4 most frequent usages:

  • to detect catfishing
  • to find fake dating profiles
  • to find revenge porn
  • to find memes.

How to detect catfishing?

Thanks to face recognition search engines you can effectively check if someone has not been using your identity to lie to people online. This con, called catfishing, is one of the most common internet crimes. It usually comes down to extorting money or stealing data. Unfortunately, it is very difficult to detect on your own. 

 

Usually, you find out about being a victim of catfishing when you receive a message from someone who has been deceived by a catfish. There are two scenarios: this person tries to find you because they think you’re a fraud or they try to find you to inform you that your identity has been stolen. Whatever the scenario, your name and image have been tarnished and you have to clear them, usually by means of legal action. 

 

But, since you’re here, you can check yourself if someone hasn’t stolen your identity. Just upload an image containing your face. If you notice that your photos have been found on websites you haven’t uploaded them to, you should start to worry.

The problem of catfishing is very closely connected to another identity issue - fake dating profiles.

How to find a fake dating profile?

Impersonating someone is one of the biggest problems on the Internet and it is commonly found in online dating. There are a lot of scammers who try to take advantage of vulnerable people looking for a relationship or commitment. 

 

It is understandable that it is difficult for people to keep a cool head when they’re emotionally involved. That is why tools like face recognition search engines are a great help when people feel unsure of their online dating partners. Using just a single photo and a face recognition search engine anyone can check if the person they are talking to:

  • appears on many online dating sites
  • uses the same personal data on different dating portals
  • can be found on other websites (to verify if this person exists in the real world)
  • or can be found on websites/pages on which users warn each other about fake profiles and frauds.

Afraid of fake dating profiles? Use a face recognition search engine to find if you talk to a real person

How to find photos used as revenge porn?

If you are afraid that someone (usually an ex-partner) has published your naked photos online without your consent, a face recognition search engine is the perfect tool for you to find that out. Upload your photo and check where your face appears online. Images that might be inappropriate for minors are marked as “Potentially explicit content”.

How to use a face recognition search engine to find memes with your face?

The situation where an image with your face is used to create memes is much less common than the previously mentioned cases. But it may cause as much harm as they do. Memes are usually created using images of well-known people who have to accept the fact that they are public figures and their image might not be as protected as they would like. But sometimes they appear in the company of ordinary mortals. When an average person appears in a photo with a celebrity or a politician, willingly or incidentally, he or she might become a part of the meme. 

 

You can also become the main character of a meme when someone uses your face in bad faith, for example for revenge. As you know, memes go viral, so if someone creates a funny or scandalous image and pastes the photo of your face into it, it might be difficult to control the spreading of this “creation”. Using PimEyes, you can check if somebody hasn’t used your picture to create a meme or other content that shows you in a bad light.

What is PimEyes’ database? 

Our database is a list of websites that contain pictures with faces. We don’t collect or store photos of people’s faces. We also don’t store or even look for personal data. 

 

Our index consists of websites that:

 

  • are publicly available (like the news, media, blogs, company websites, etc.)
  • allow bots to crawl their data.

 

We collect only legally obtained data, consistent with the information in the robots.txt file on a given website. We don’t search social media (these kinds of platforms don’t allow crawling their data) or video platforms, including public profiles (e.g. companies, influencers, brands).

Face-search using PimEyes

Using PimEyes you can find out where your face appears online. PimEyes works like other popular search engines - when you perform a search using the right form of request (on Google it is a phrase, on PimEyes - an image containing a face), you receive matching results, displayed from external websites. 

 

For example: on Google, when you type: “Headphones Bluetooth”, in the search results you’ll receive a list of links to: online stores offering headphones, articles with headphone comparisons, articles about Bluetooth technology, etc. On PimEyes, when you upload a photo to perform a search, in the results you’ll get links to websites on which this photo or similar photos appear. 

What happens to an image once it has been uploaded to PimEyes?

The photo you have uploaded to perform a search is saved only temporarily for 48 hours. Then it is automatically removed. We do not store any private data from our users.
