International Classification:

Abstract:

Systems and methods for timestamp-based matching of identifiers are provided. Information may be stored in memory regarding a plurality of identifiers each unique to an associated website or to an associated browser. Stored information may further include one or more maps each associating a device identifier with at least one immutable browser identifier or mutable browser identifier. The device identifier may be unique to an associated computing device. Information may be received from a computing device that has used a browser to download a website, where the downloaded website includes a reference to a browser identifier specific to the downloaded website. The received information may be determined to include a timestamp and an internet protocol (IP) address. The timestamp and IP in the received information may further be determined to correspond to a computing device associated with one of the stored maps, where the corresponding computing device is identified by a corresponding device identifier. The stored map associated with the corresponding device identifier may be updated based on the referenced browser identifier.

H04L 29/08

Abstract:

Systems and methods for associating sessions using (TCP packet-level) timestamps are provided. A collection of data packets received during one or more sessions within a time period may be retrieved. Each packet in the collection may be associated with a unique identifier of a respective session. A skew for a selected session within the time period may be determined based on a rate difference between a respective receiving device clock and a respective sending device clock of at least two data packets associated with the unique identifier of the selected session. The selected session may be associated with a computing device. An uptime may be calculated for each of the retrieved data packets based on the determined skew and respective timestamp information of the data packet. It may be identified as to whether each of the calculated uptimes matches a previously calculated uptime for a packet associated with a previous session or a session that has previously been associated with a selected session. A list of sessions associated with the computing device may be updated based on one or more identified matches between the respective calculated uptime and the previously calculated uptime.

International Classification:

H04L 12/24

Abstract:

Systems and methods for session-based matching of mutable browser identifiers are provided. Information may be stored regarding a plurality of mutable browser identifiers each unique to an associated website and one or more maps each associating a immutable browser identifier to one or more mutable browser identifiers. Such a immutable browser identifier may be unique to an associated browser. Further, information may be received from a computing device that has used a browser to download a website. Such downloaded website may include a reference to a mutable browser identifier specific to the downloaded website. The referenced mutable browser identifier may be identified as corresponding to one of the stored mutable browser identifiers. The session information of the referenced mutable browser identifier in the received information may be compared to the session information of the corresponding stored mutable browser identifier. Stored information associated with the corresponding stored mutable browser identifier may be updated based on the comparison.
