Abstract

A digital fingerprint identifying a device includes characteristics of a user of the device in addition to characteristics of the device itself. The personal characteristics used to form the digital fingerprint of the device are those that are likely to not change over time or to change in predictable ways. The personal characteristics are gathered from sources external to the device, such as profiles of the user stored remotely at a social networking site. Each constituent characteristic of a digital fingerprint is associated with extraction logic and comparison logic.

Claims

exact text as granted — not AI-modified
1 . A method for identifying a remotely located device, the method comprising:
 sending characteristic extraction logic to the remotely located device, wherein the characteristic extraction logic causes the remotely located device to retrieve characteristics of the device and at least one characteristic of a user of the device from a publicly available profile of the user of the device;   receiving a digital fingerprint of the device from the device, wherein the digital fingerprint includes data representing the characteristics of the device and at least the characteristic of the user of the device; and   comparing the digital fingerprint of the device to a reference digital fingerprint to determine whether the digital fingerprint of the device and the reference digital fingerprint identify one and the same device.   
     
     
         2 . The method of  claim 1  wherein the characteristic extraction logic causes the remotely located device to retrieve the characteristic of the user of the device by at least:
 identifying the publicly available profile of the user of the device from browser personal information stored in the device. 
 
     
     
         3 - 15 . (canceled) 
     
     
         16 . The method of any one of  claim 1  or  2 , wherein the characteristic extraction logic causes the remotely located device to retrieve the characteristic of the user of the device by at least also:
 retrieving the publicly available profile through a computer network. 
 
     
     
         17 . The method of any one of  claim 1  or  3 , wherein comparing comprises:
 retrieving comparison logic associated with each of the characteristics of the device and the characteristic of the user of the device; and 
 executing the comparison logic to determine a degree of similarity between the digital fingerprint of the device to a reference digital fingerprint. 
 
     
     
         18 . The method of claim  4  wherein the comparison logic associated with the characteristic of the user of the device considers changes in the characteristic of the user of the device over time relative to expected changes in the characteristic of the user of the device over time. 
     
     
         19 - 24 . (canceled)
