Method and Apparatus for Correlating Multiple Cookies as Having Originated from the Same Device Using Device Fingerprinting

摘要

Information that is useful to distinguish between two or more computer devices (a “device fingerprint”) is collected and stored in a database with corresponding state-management tokens such as HTTP cookies. The database is searched for a fingerprint, and if the fingerprint is found, the corresponding stored token is delivered to a computer device for the device's use in making subsequent requests for resources or services.
