Image Sensor and Payment Authentication Method

Abstract

The invention relates to an image sensor and a payment authentication method. The image sensor includes: a sensing module configured to optically sense an image and to convert an optical signal of the image into an image signal; and an encryption module configured to encrypt the image signal and to output the encrypted image signal. The payment authentication method includes the steps of: converting an individual image into an image signal by an image sensor, wherein the image sensor includes a sensing module configured to optically sense an image and to convert an optical signal of the image into an image signal and an encryption module configured to encrypt the image signal; encrypting the image signal by the image sensor; and transmitting the image signal processed in the preceding step. With the image sensor and the payment authentication method of the invention, the security of mobile and remote payment may be greatly improved.
