Recently, some Chinese experts advised people to be more careful about making a “V” gesture (手势) while taking a photo, because the fingerprints(指纹) might be stolen.

It is possible．If the distance(距离) between the person and the smart phone is less than half a meter, the possibility of the fingerprint being stolen will be bigger．Having fingerprints stolen can cause a lot of trouble, as they are used in many things, including ID cards, passports and online payments．So it’s a must to pay attention to the protection of them and avoid them being spread on the Internet.

This kind of discussion was first raised by a Japanese research center, the National Institute of Informatics.

Zeng Qiaoyi, 19, who likes sharing selfies(自拍) on WeChat, said she was also worried about it．She said she seldom posted pictures with “V” gestures and most pictures she shared were made to be not so clear by certain software．“ I blur the backgrounds in selfies, hoping to hide my location,” she added.

Tan Tieniu, a scientist, said at the 2016 China National Computer Congress that using fingerprints instead of passwords or voice identification is far from safe, compared with face recognition (识别).

But a police officer from Jiangsu Province said locals didn’t need to be overly anxious, because the cameras of many cell phones were not clear enough, and the shooting distance of most photos taken by cameras was too far.
