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.
