>> Smiling robots, drones, and machines that scan your footprints. They're just a few of hundreds of security gadgets at this police expo in China. A peek into the race to supply Beijing's growing surveillance state. Among the hottest items, phone scanners like this one. Sellers claim the machines can crack your smartphone password and rip data and contacts from your device.
Several companies here told Reuters they could even crack four-digit iPhone passwords on older versions of Apple's iOS. Many analysts see iOS as the most secure operating system, but some sellers here even claim they're on their way to cracking iOS 10 this year. Reuters Pei Li says that demand for surveillance gadgets, or black tech, is soaring in China.
>> China's security forces are increasingly using technology to monitor and punish any behavior that runs counter to the ruling communist party. For example, the law enforcement are able to use facial recognition eyeglasses to identify any suspects. They can also use phone scanners to glean the data out of your phone and detect any content that is terrorism or violence related.
>> In the far west region of Xinjiang, similar types of scanners are already being put to use. Authorities are upping surveilance there to closely track Muslim Uyghurs, a minority group. Now China is looking to go a step further and create a nationwide surveillance web with the help of devices like these.
>> Houseline Technology, a Beijing based company, told me their forensic phone scanning devices already widely used in 26 provinces in China, and they have already helped the police process over 11 million cases.>> Rights activists overseas say they're worried over the rise of black tech in China. They fear it wil leave the country's smartphone mad population with little private space, but any public debate over privacy is quiet, with many resigned the fact that in China, individual rights take a backseat to state security.
