紧急提醒！拍照比“剪刀手”，小心泄露指纹信息
双语君约 3 分钟The popular "V" or peace sign hand gesture often seen in photos may pose an unexpected biometric security risk, experts have warned.
The issue gained attention after a workplace reality show highlighted the risk. During the program, financial analyst Li Chang said fingerprints may be extracted from close-range photos showing clear fingertips, particularly when hands are directly facing the camera.
According to him, images captured within 1.5 meters may allow nearly complete extraction of fingerprint details, while the success rate declines significantly as distance increases.
这种情况发生的可能性有多大？
中国科学院大学教授荆继武表示，如果用“剪刀手”拍照，好一点的相机拍摄单人像可能能够还原指纹。现在的相机一般能够达到1200万像素，也就是说拍一米长的物体，分辨率可达0.25毫米，利用多张照片有可能恢复指纹。一般情况下由于光线、聚焦等原因，恢复有一定难度，但更高精度的相机恢复起来就简单些。
Experts say improvements in camera technology have made fingerprint extraction more feasible. Jing Jiwu, a professor at the University of Chinese Academy of Sciences, said high-resolution cameras can capture fine details, while multiple clear images may help reconstruct fingerprint patterns under suitable conditions.
其实，任何方式泄露指纹都可能威胁到用户的信息安全。如果拥有了你的指纹，就可能模仿你进行身份假冒，就有可能开一般的指纹电子锁，也可能模仿上班进门的指纹打卡等。
Experts warned that stolen biometric data could be used for identity fraud, including unauthorized access to fingerprint-enabled locks, workplace attendance systems, and other authentication devices.
此事引发网友广泛讨论。有网友调侃，还好自己一直用美颜相机拍照......
不少网友已经想好了以后的拍照姿势：
The discussion has also raised concerns over seemingly harmless online activities, such as sharing close-up hand photos for entertainment apps or palm-reading games, which could unintentionally expose sensitive personal data.
