Utilizing multiple computing devices to verify identity

摘要

A tool for identify verification using computing device collaboration. The tool generates a hash based, at least in part, on device specific information for one or more user owned devices. The tool determines whether a hash for the initial device matches the hash for at least one of the one or more user owned devices, and if so, sends, one or more challenge questions to the initial device, wherein the one or more challenge questions include at least one challenge question based on the device specific information for the one or more user owned devices. The tool determines whether each of one or more responses to the one or more challenge questions is correct.

1. A method for improving identity verification using a topology of trusted devices, the method comprising:
generating, by one or more computer processors, a hash based, at least in part, on device specific information for one or more user owned devices, the device specific information for the one or more user owned devices registered in a user account; in response to receiving a request from an initial device to verify a user's identity, determining, by one or more computer processors, whether a hash for the initial device matches the hash for at least one of the one or more user owned devices, wherein determining whether the hash for the initial device matches the hash for at least one of the one or more user owned devices includes querying the initial device for one or more of its device attributes; incorporating one or more device attributes of the initial device into a pre-determined sequence initially used for generating the hash for each of the one or more user owned devices registered in the user account; and determining a sequence of the hash for the initial device matches the pre-determined sequence of the hash for at least one of the one or more devices registered in the user account, wherein the sequence of the hash for the initial device matches the pre-determined sequence of the hash for at least one of the one or more devices registered in the user account when each value for both sequences match; and if so, sending, by one or more computer processors, one or more challenge questions to the initial device, wherein the one or more challenge questions include at least one challenge question based on the device specific information of at least one additional device from the one or more user owned devices; and determining, by one or more computer processors, whether each of one or more responses to the one or more challenge questions is correct.
