How Tencent’s Cross‑Age Facial Recognition Helps Find Missing Children
Tencent’s AI‑driven cross‑age facial recognition technology, developed by Youtu Lab, enables authorities to locate missing children by matching photos taken years apart, a capability demonstrated in the QQ City‑wide Assistance program that has reunited dozens of families and earned international awards.
At the 2017 Guangzhou Fortune Global Forum, Tencent’s Chairman and CEO Ma Huateng highlighted the company’s strong facial recognition capabilities, emphasizing a newer AI technology that can predict how a person will look as they age. This cross‑age facial recognition, created by Tencent Youtu Lab, has been applied in the public‑welfare project QQ City‑wide Assistance.
In June 2017, the platform successfully located a three‑year‑missing boy in Henan Province by matching a recent photo with a decade‑old image, confirming his identity as the missing child. The technology has since been used to help reunite families and assist law‑enforcement agencies.
Through the “Face‑Find Family” feature, users upload a photo of a missing person; the system searches a database of missing‑person photos, instantly presenting matches. Even if the database contains only adult photos, the cross‑age algorithm can match them with childhood images, greatly improving search accuracy.
The “Hope Never Dies” case from QQ City‑wide Assistance won the Gold Lion for “Use of Social Data & Insight” at the Cannes International Creative Festival, showcasing the social impact of the technology.
Since its launch in 2014, QQ City‑wide Assistance, which leverages mobile‑internet location services and integrates data from “Baby Home” and the Ministry of Civil Affairs, has collaborated with the Ministry of Public Security to publish 481 child‑missing cases (302 recovered), 210 elderly cases (75 recovered), and 106 rare‑blood‑type cases (98 solved).
