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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Timestamp-based matching of identifiers","description":"Systems and methods for timestamp-based matching of identifiers are provided.
