Unusual Uses of Facial Recognition Technology

Posted November 5, 2018

In 2017, the global facial recognition market was valued at more than 4 billion USD and it is expected to reach 10 billion USD by 2023. Although this technology used to be associated with security sector, today it proliferates extensively to other industries as well.

Expansion of this technology and availability of easy-to-use biometric products gives rise to a number of rather unusual application scenarios one could hardly imagine before.

Easier and shorter marriage registration

Who could have believed that one day high-tech would even enter the realm of spiritual things such as marriage?

On January 7, 2018 the authorities in Chongqing introduced a face recognition system for marriage registration to make the procedure easier and shorter.

After a picture is taken, the system extracts a face and validates against the information available from other documents and the database of the public security bureau. Facial recognition allows to complete an ID check in just 0.3 seconds, whereas it would normally last as many as 10 minutes without such an aid.

Child adoption

A project, called “Twin Souls”, is using cloud-based facial identification for a very kind and generous purpose. The mission of this project is to help finding an orphan in Russia, who looks like you or your child, and then to adopt him/her with the assistance of Change One Life foundation.

After uploading your picture (or your child’s picture) onto the website, a facial recognition algorithm searches for the most similar kids in a huge database of Russian orphans. Each orphan has an account to introduce himself/herself. It is not required to immediately adopt the child, the project creators want adults to feel the connection with some kid and make them think – how they can help him and other orphans.

Students behavior monitoring in a classroom

A high school in China, Hangzhou, uses a facial recognition camera that scans the classroom every 30 seconds. The system is designed to log behavior of six types: writing, reading, standing, hand raising, listening to the teacher and leaning on the desk. It also records the emotions of the students such as happiness, disappointment, anger, fear and disgust.

All the collected information is analyzed and reported to the teachers. However, the system does more than just analyzing student behavior. Students can buy lunch in the canteen, purchase goods at the school shop and borrow books from the school library by using this system as well.


Marriage registration, child adoption and monitoring student behavior in schools are just a few examples of novel use cases. As there are virtually no limits for human creativity and imagination, in the near future we will see more and more ways to put facial recognition technology to good use.
