Technology is bringing hope to all incomplete families. We cannot stop lost children from changing, but we are able to make more reunions possible with better technology.

The stray cases occurs every day, but only a handful of lost people are recovered. Because of the great changes of physical appearance caused by time accumulation, it becomes very difficult for people to find their missing kinsfolk through old photos. QQ is going to change all this. Equipped with the state-of-art facial recognition technology, and a database of more than 10 millions samples, it has conducted billions of trials.The cross-age face match accuracy achieves up to 99.8%. No matter how long the child has been abducted, one day or decades, as long as his/her family uploads the child’s photo, QQ Alert will start the Large-Scale Face Retrieval in massive photo gallery at a rate of 50 million sheets per second. The system will present the face matching results instantly and help people recognize their beloved missing folks.

Children abduction cases occur in China every day, but only a few children who have been abducted can be recovered in a short time. Due to the cumulative time, the great changes of facial appearance has made it extremely difficult for people to find their beloved families by old photos. It has led to the majority of those who have been abducted cannot reunite with their families for several years or even decades. As one of the biggest social platforms in China, QQ Instant Messenger has more than 860 million users.

QQ has Launched the “QQ Alert” project, which helps desperate people find their missing kinsfolk. We are able to make more reunions possible with better technology.
