DEVICE AUTHENTICATION USING INTER-PERSON MESSAGE METADATA

摘要

A device authentication server authenticates a remotely located device using unique data associated with the user of the device stored on a remotely located server that has an established relationship with the device, such as client logic installed on the device and authentication data of the user stored on the device. The unique data can be unique metadata associated with inter-person messages. Since each user receives and sends a unique collection of messages, the unique message meta-data associated with a user's account is, in aggregate, unique.

1. A method for identifying a remotely located device, the method comprising:
receiving device identification data from the device, wherein the device identification data includes:
a device identifier, wherein the device identifier is a unique identifier of one of a number of known devices; andmessage metadata, wherein the message metadata represents one or more metadata of one or more inter-person messages associated with the device;determining that the device identifier identifies the device;determining that the message metadata is consistent with corresponding reference message metadata previously stored for the device; andauthenticating the device as a recognized device upon determining that the message metadata is consistent with the corresponding reference message metadata.
