Alibaba's Latest Payments Innovation: Selfie-Powered TransactionsThe ecommerce giant is taking another step into the world of mobile payments – this time, using the selfie as an authentication tool.

Asmobile paymentsbecome more a part of the business landscape, the question of how to make them safer is top of mind. Alibaba -- the vast Chinese ecommerce company that closed out 2014 with the biggest U.S.-based IPO to date -- has a solution.

This week, Alibaba founder Jack Ma spoke at theCeBitconference in Hanover, Germany and demonstrated a new service called "Smile to Pay" that would give consumers a password-free way to shop online. The service would allow users to make a purchase from their mobile phone, then require them to snap a selfie to authenticate the purchase using Alibaba's facial recognition technology.

Alibaba owns anonline payment platformcalled Alipay, which has a complicated back story. It was launched in 2004 to be used for Taobao, an online marketplace comparable to eBay. In 2011, it was spun off into its own entity under the control of a company called ANT Financial (which in turn was founded by the Alibaba Group).
