緊急提醒！拍照比“剪刀手”，小心泄露指紋信息

很多人拍照時都喜歡比 “剪刀手”，但你可能想不到，這個看似平常的姿勢其實暗藏風(fēng)險。

The popular "V" or peace sign hand gesture often seen in photos may pose an unexpected biometric security risk, experts have warned.

近日，一檔職場綜藝熱播，節(jié)目里的新型騙局案例迅速引發(fā)網(wǎng)友熱議，相關(guān)話題登上社交平臺熱榜。

節(jié)目中，金融專家李暢指出，拍照時擺出剪刀手、清晰露出指紋，可能會導(dǎo)致個人信息泄露。1.5米以內(nèi)的拍照，如果手是完全對著鏡頭的話，可以100%提取手部信息。1.5米到3米可以提取50%，3米以上才基本上不太能識別到手部的信息。

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.

專家提醒，大家面對鏡頭時，手掌、手指露出的信息一定要及時打碼。同時，切勿在他人設(shè)備上錄入自己的指紋，這直接關(guān)系到個人賬戶與資金安全。

這種情況發(fā)生的可能性有多大？

專家解讀

中國科學(xué)院大學(xué)教授荊繼武表示，如果用“剪刀手”拍照，好一點的相機拍攝單人像可能能夠還原指紋。現(xiàn)在的相機一般能夠達(dá)到1200萬像素，也就是說拍一米長的物體，分辨率可達(dá)0.25毫米，利用多張照片有可能恢復(fù)指紋。一般情況下由于光線、聚焦等原因，恢復(fù)有一定難度，但更高精度的相機恢復(fù)起來就簡單些。

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.

其實，任何方式泄露指紋都可能威脅到用戶的信息安全。如果擁有了你的指紋，就可能模仿你進行身份假冒，就有可能開一般的指紋電子鎖，也可能模仿上班進門的指紋打卡等。

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.

此事引發(fā)網(wǎng)友廣泛討論。有網(wǎng)友調(diào)侃，還好自己一直用美顏相機拍照......

不少網(wǎng)友已經(jīng)想好了以后的拍照姿勢：

也有網(wǎng)友提醒，看手相等需要拍照的測試游戲，同樣存在信息泄露風(fēng)險，希望大家提高警惕。

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.

轉(zhuǎn)發(fā)提醒！
