Systems and methods for anonymous authentication using multiple devices

Abstract

A system and method of anonymous authentication is described. In operation, the authenticator receives a request to access a resource from one of the user devices of an associated set of user devices, wherein each of the user devices is registered to at least one user requesting access to the resource registered to at least two users. The authenticator generates and transmits an authentication challenge in response to the request to a subset of the user devices. A user device subsequently generates and transmits a response to the authentication challenge to the authenticator. The authenticator determines whether the responses received from the one or more user devices constitutes a valid response and grants any one or more of the user devices of the associated set of user devices access to the resource if the responses received from the user devices constitutes a valid response to the authentication challenge.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims priority to currently pending U.S. patent application Ser. No. 14 / 693,490, entitled “Systems and Method for Authentication Using Multiple Devices”, having a filing date of Apr. 22, 2015, which claims priority to U.S. Provisional Patent Application No. 62 / 095,137, entitled “Systems and Method for Authentication Using Multiple Devices”, having a filing date of Dec. 22, 2014, both of which are hereby incorporated by reference.BACKGROUND[0002]A traditional method of authentication can involve prompting a user for a username and password. However, such a method of authentication can be prone to error and can require the user to recall hard-to-remember passwords.[0003]Another traditional method of authentication can involve receiving a unique property of the user, such as a fingerprint, to identify a user. However, such a method of authentication can be vulnerable to discovery of the user property. For example, an attack...

AI Technical Summary

Benefits of technology

The present invention proposes a system and method for verifying the identity of a group of users by requiring them to use multiple devices for authentication. This approach increases security and anonymity as it prevents unauthorized access through a single device and prevents the authentication system from learning which user has gained access.

Problems solved by technology

However, such a method of authentication can be prone to error and can require the user to recall hard-to-remember passwords.

However, such a method of authentication can be vulnerable to discovery of the user property.

However, such a method of authentication can be attacked by stealing the token.

Additionally, the traditional methods of authentication do not provide anonymity for a user requesting authentication.
