Described herein are methods and systems for generating a mobile device-specific identifier usable across native mobile applications and mobile browsers with a unified opt-out mechanism. A mobile device generates a transient identifier for the mobile device and maps the transient identifier to a stable identifier of the mobile device using at least one call to a service endpoint coupled to the mobile device via a communications network. A browser application on the mobile device renders a webpage, the webpage comprising first instructions, executed by the browser application, to retrieve the stable identifier of the mobile device using at least one call to the service endpoint coupled to the mobile device via a communications network.

Generating mobile device-specific identifiers across native mobile applications and mobile browsers

Systems and methods for identifying one or more candidate computing entities associated with a first user of a first computing entity are disclosed. A first technical ID associated with the first computing entity and one or more parameters associated with the first computing entity are received by the ad system. A first identity fingerprint for the first computing entity is determined by the ad system. One or more candidate computing entities are identified by the ad system based on a similarity between the first identity fingerprint and an associated identity fingerprint of the one or more associated identity fingerprints of the candidate computing entity. First behavioral data is determined by the ad system based on the associated behavioral data of one or more of the one or more candidate computing entities. An advertisement based on the first behavioral data is provided by the ad system.

Runtime matching of computing entities

Described are methods, systems, and apparatus, including computer program products for provision of cross-device identifiers. A cross-device ID is assigned by a computing entity matching system on a first domain to a browser and to one or more computing entities. A request for a webpage is sent by the browser to a server on a second domain. The webpage, including cross-device ID retrieval instructions, is received by the browser. The cross-device ID retrieval instructions are executed to send a request to the computing entity matching system including a matching system ID. The cross-device ID is determined based on the matching system ID. Cross-device ID storage instructions, including a distributed cross-device ID, are sent by the computing entity matching system. The cross-device ID storage instructions are executed by the browser. A request for a webpage, including the distributed cross-device ID, is sent by the browser to the server.

Provision of cross-device identification

Methods and systems for setting first-party cookies are disclosed. A first request for a first webpage is sent by a user device to a first web server on a first domain. The first webpage includes first ad system call instructions. The first ad system call instructions are executed to send a second request to an ad system on a second domain to initiate determining a supply side platform (SSP) user ID. First SSP call instructions are received by the user device. The first SSP call instructions are executed to send a third request to an SSP server on a third domain. Second ad system call instructions including the SSP user ID are received by the user device. The second ad system call instructions are executed to send a fourth request comprising the SSP user ID to the ad system. First storing instructions for the SSP user ID are received.
