RECOGNITION-BASED AUTHENTICATION, SYSTEMS AND METHODS

摘要

An authentication engine authenticates a user to access a service via a computing device by executing an object recognition algorithm on an image received from a different computing device. Specifically, the authentication engine presents an image token on a first computing device after receiving a request. The authentication engine then instructs the user to use a second computing device to capture a digital photo of the image token. Upon receiving the photo from the second device, the authentication engine executes an object recognition algorithm on the photo to derive a set of image descriptors. The authentication engine then generates an image difference by comparing the set of descriptors of the photo against the set of descriptors of the image token. Based on the image difference, the authentication engine authenticates the user to use a service via the first computing device.

主权项

1. A method of initiating a handshake between a first device and a second device, comprising:
instructing, by an authentication engine, the first device to present an image token to the second device, wherein the image token is associated with a first set of image descriptors previously derived from the image token; receiving, at the authentication engine, image data from the second device, the image data being representative of a photo of the image token presented on the first device; deriving, by the authentication engine, a second set of image descriptors from the image data; generating, by the authentication engine, an image difference between the image token and the image data by comparing the first set of image descriptors and the second set of image descriptors; and initiating, by the authentication engine, a handshake session between the first and second devices as a function of the generated difference.
