Eye spy

A new biometric camera and database network could make it hard for bad guys to hide. Cheng Anqi reports.

Li Ziqing felt he needed to do his part when authorities started a nationwide campaign to nab fugitives and kidnappers. The Center for Biometrics and Security Research (CBSR) professor and his team spent the following months creating a database enabling netizens to collect and share photographs, information and tips online.

"People can secretly snap and upload photos of people who appear suspicious or who may have kidnapped children," Li explains.
