2元就能買(mǎi)上千張人臉照片！“刷臉”真的安全嗎？

如何增強人臉識別安全性？

專(zhuān)家表示，目前最簡(jiǎn)單的人臉識別，只需要采集、提取人臉上的6個(gè)或8個(gè)特征點(diǎn)就能實(shí)現。而復雜的人臉識別，則需要采集、提取人臉上的數十個(gè)乃至上百個(gè)特征點(diǎn)才能實(shí)現。相比于解鎖手機，“刷臉”支付、“刷臉”進(jìn)小區等應用，采集的人臉特征點(diǎn)更多，安全性自然也更高。

此外，目前已經(jīng)研發(fā)出了專(zhuān)門(mén)針對生物特征的活體檢測技術(shù)，可有效識別掃描對象的生命體征，大大降低了識別系統把照片或面具當人臉的風(fēng)險。
