杭州一肯德基店支持刷脸支付,未来“你的脸”就是通行证?

2017-09-02 20:45:52   新华网

新华社杭州9月2日电(记者张璇 屈凌燕)1日,支付宝宣布在杭州一家肯德基的KPRO餐厅上线刷脸支付服务:不用手机,通过刷脸即可支付。支付宝称,这是刷脸支付在全球范围内的首次商用试点。

记者了解到,商用试点是实验室走出的“第一步”。由于刷脸支付是在线下公共设备和开放环境下进行,真实场景复杂多变,且安全性要求更高。刷脸支付首度进入商用到底安全吗?

不用手机、不输密码

在杭州万象城肯德基的KPRO餐厅里,记者体验了一把“看脸吃饭”:在自助点餐机上选好餐,进入支付页面,可选择继支付宝、微信移动支付选项后的新选项“刷脸支付”,然后进行人脸识别,大约需要1-2秒,再输入与支付宝账号绑定的手机号,确认后即可支付。支付过程不到10秒。如果是首次使用,用户需要先在支付宝APP上开通此功能。

消费者黄莺在点单后,拿上叫号机扫一扫,在支付页面选择了刷脸支付,首先跳出来的是人脸识别页面,识别成功后输入手机号码,双重验证通过后,即可完成支付。“我觉得挺新奇,用起来也挺方便。”黄莺笑着说。

据介绍,刷脸技术来自于支付宝的刷脸支付“Smile to Pay”应用。“在肯德基上线,是‘刷脸支付’迈出实验室的第一步。”蚂蚁金服首席技术官程立介绍说。

据蚂蚁金服方面称,自2015年起,支付宝将人脸识别技术应用于用户登录后,这一技术先后用于实名认证、找回密码、支付风险校验等场景。

 首度商用拷问“刷脸支付”安全几何?

有网友对“刷脸”技术存在质疑:双胞胎能分辨吗?过度化妆、整容能分辨吗?蚂蚁金服生物识别技术负责人陈继东称,经过不断优化,目前支付宝的人脸识别准确率已远超肉眼,而且有活体检测算法来判断采集到的人脸信息是否为照片、视频等冒充。

据介绍,支付宝在肯德基KPRO的点餐机上配备了3D红外深度摄像头,在进行人脸识别前,会通过软硬件结合的方法进行活体检测,来判断采集到的人脸是否是照片、视频或者软件模拟生成的,避免各种人脸伪造带来的身份冒用情况。

蚂蚁金服方面说,支付宝是最早实现刷脸登录的金融级APP。有业内人士称,刷脸登陆有助于人工智能的深度学习,为“刷脸支付”进入商用做准备。陈继东表示,通过软硬件的结合,智能算法与风控体系综合保证金融级准确性和安全性,“而即便出现账户被冒用的极小概率事件,支付宝也会通过保险公司全额赔付。”
