Amazon goes after patent so you can pay by selfie

Amazon filed a patent application for a technology that would enable users to pay for purchases using a selfie.

The U.S. patent application is for image analysis technology for user authentication.

"The process identifies the user and verifies that the user requesting the transaction is a living human being," the application states. "The user is identified using image information, which is processed utilizing facial recognition."

Amazon explains that the user authentication would work by verifying that the image or video is of a live human using one or more "human-verification" processes. The device would then prompt the user to perform a specific action, such as making a specific hand gesture or blinking the left eye, to confirm the transaction.
