Cookie derivatives

摘要

Cookie derivatives and methods for generating cookie derivatives are provided. A cookie derivative comprises a transformation of at least one portion of data associated with a cookie (e.g., a name and/or data value). The cookie derivative may comprise a persistent or non-persistent cookie derivative that may be stored on a user's computing device (e.g., within a browser). The cookie derivative may alternatively comprise a virtual cookie derivative that is stored on a server (e.g., in a log file, a cache, or other data storage of the server).

主权项

1. A method for providing a virtual cookie derivative comprising:
receiving a request for content at a first party server, the request for content including at least one cookie associated with a first party domain of an advertiser; transforming a value component of a name/value pair of cookie data associated with the at least one cookie in response to the request for content to generate a temporary virtual cookie derivative at the first party server, the temporary virtual cookie derivative residing on the first party server for a limited period of time and comprising a derivative data value derived from the data associated with the at least one cookie wherein the operation of transforming cookie data comprises removing privacy related information of the cookie data, wherein the temporary virtual cookie derivative is discarded or written over after a limited number of transactions; passing the virtual cookie derivative to a third party ad server outside of the first party domain of the advertiser; evaluating, at the third party ad server, the derivative data value of the cookie derivative against targeting data to determine advertisement content to be returned in response to the request for content; and returning the determined advertisement content from the third party ad server in response to the request for content, wherein the at least one cookie is not modified at a client browser.
