The project consisted of the following modules :

Face detection

Within the framework of the project, an implementation of the algorithm for face detection was made. It is characterized by high speed in real time, as well as high efficiency. Additionally, it is resistant to objects covering the user’s face such as glasses or a hat.

Liveness detection (detection of user’s life span)

Based on deep learning technology, a binary classifier was made to recognize the user’s lifetime during verification. The system verifies if there is a real person on the supplied camera image. In the case where a sheet of paper with a face or a photo from the phone was shown, the algorithm did not let the user through to the next stage.

User age estimation

On the basis of the face photo, detected with the use of face detection methods, a solution has been developed to verify the age of the user. This algorithm in the precise way solves the problem of determining the age of the person, transforming the problem to the task of the multi-class classification (the supported age range is 0-100 years). The solution was based on the scientific research from the estimation of the age on the basis of the face which resulted in the development of the winning model in the contest ChaLearn LAP 2016, in which 115 teams from all over the world took part.

Age verification with the use of identity card

Using the optical character recognition system (OCR) we have made a system to verify the age of the user based on the age given in the proof. After the optical character recognition was done, the date of birth was read, on the basis of which the age of the holder of the proof was calculated.

User verification with ID card

With the use of deep learning methods we implemented an algorithm for face identification of one-shot-learning type. The model is able to determine the compatibility of the photos on the basis of only two images, although he has never seen these images. This solution was used in verification of the user with his identity card.
