Welcome to Verified by Pi!

These Terms and conditions govern your use of Verified by Pi and provide information about the Verified by Pi services, outlined below. When you create an account on Verified by Pi or use our services, you agree to these terms. 

The Verified by Pi is a software product of Serbian IT company “Technology Partnership”, so these Terms and conditions are a legally binding contract between you and “Technology Partnership” (TP). This contract sets out your rights and responsibilities when you use Verified by Pi application and website, so please read it carefully. 



We are providing you with Verified by Pi software, currently available for the Android platform. It is a tool that automatically, in a unique way, verifies the authenticity of your photos. Using this application makes it easy to find out whether an image is authentic or at least somewhat processed. Just one click, or just a fraction of a second, is enough for the user to obtain a certificate of authenticity and proof of authenticity of the photo. The Verified by Pi services are based on the block-chain technology. 

How we do that?

The Verified by Pi application is started by simply clicking on the appropriate button to activate the service. This opens a page in the program where the photo can be verified. Selecting the first option activates the camera on the phone through which a photo can be taken. The difference with the standard camera application is that the user here also has a special button through which the user can see the photo on which the “Verified by Pi” security mark is added, as well as the corresponding QR code.

Photo verification is done by calculating its hash value and adding a cryptographic signature, which is further sent to a secure server. The hash value and the cryptographic signature are later used to identify the photograph. Any modification will change both the hash values ​​and the cryptographic signature, so they will not match the information stored on the server. This is irrefutable proof that the photo was modified.

The process is very simple:

1) Original photo. The user opens Verified by Pi Android App or Integrated Camera and takes a photo using any available camera.

2) Verified photo. Using Verified by Pi technology, the photo is being taken and verified at the same time which eliminates any possibility for faking. The cryptographic signature of the taken photo is securely saved on servers that could be hosted by TP or any desired provider.

3) Editing photo. Any later modification of the photo will change its cryptographic signature and invalidate verification.

4) Photo is modified. After the photo was modified, the usage of Verified by Pi technology will prove that the photo is fake.

5) Compare. The user makes the verification request for the desired photo available on the phone storage. A symbol in the top right corner of the screen indicates if the photo is real or fake.



Users will need to create a Verified by Pi account in order to use Services. Here are a few rules about your account.

1) No age restriction. Minors under 18 and at least 13 years of age are permitted to use our Services through an account owned by a parent or legal guardian with their appropriate permission and under their direct supervision. Parent or legal guardian are responsible for any and all account activity conducted by a minor on the account. 

2) How to create the Verified by Pi account. To create an account for Verified by Pi application, you need to enter a valid phone number and password that you want to have. If you enter everything correctly, you will receive a confirmation on that phone number.

3) Choose an appropriate name. If you decide to not have your full name serve as the name associated with your account, you may not use language that is offensive, vulgar, or infringes someone’s intellectual property rights, or otherwise violates Terms and conditions.

4) Protect your password. The key aspects of a strong password are length (the longer the better); a mix of letters (upper and lower case), numbers, and symbols, no ties to your personal information, and no dictionary words. Please have this in mind when creating a Verified by Pi account. 

5) Responsibility. You’re solely responsible for any activity on your account. If you’re sharing an account with other people, then the person whose information is on the account will ultimately be responsible for all activity. If you’re registering as a business entity, you personally guarantee that you have the authority to agree to these Terms and conditions on behalf of the business. Also, your accounts are not transferable.



In order for us to provide you with the Services, we need you to give us the following permissions.

2) Location. Permission to access your location using GPS for high accuracy, and cellular data and Wi-Fi for approximate accuracy. Location information can facilitate the user registration process, and may also be important in cases where it is necessary to store information about where the photo was taken.
