Linking actions associated with an anonymous user to a registered user account

A device comprising:

• a processor and associated memory;
• a network interface coupled to the processor and to a communications network, the network interface configured to:
• obtain a first cookie from a first device via the communications network, wherein the first cookie includes a first identifier corresponding to a registered user identifier stored in a database, and wherein the registered user identifier is associated with first information stored in the database, the first information indicating activities related to interactions of a registered user with a first website;
• obtain a second cookie from a second device via the communications network, wherein the second cookie includes a second identifier corresponding to an anonymous user identifier stored in the database, and wherein the anonymous user identifier is associated with second information stored in the database, the second information indicating activities related to interactions of an anonymous user with a second website;
• a processor and associated memory configured to:
• correlate the first information and the second information to determine commonalities between the first information and the second information;
• in response to identifying at least one commonality of the commonalities:
• determine that the registered user and the anonymous user are a single user based on the at least one commonality;
• and
• automatically update the database to include a unified listener identifier (ULID) associating the first information with the second information by linking the registered user identifier with the anonymous user identifier.

A non-transitory computer readable medium tangibly embodying a program of instructions to be stored in a memory and executed by a processor, the non-transitory computer readable medium comprising:

• at least one instruction to obtain a first cookie from a first device via a communications network, wherein the first cookie includes a first identifier corresponding to a registered user identifier stored in a database, and wherein the registered user identifier is associated with first information stored in the database, the first information indicating activities related to interactions of a registered user with a first website;
• at least one instruction to obtain a second cookie from a second device via the communications network, wherein the second cookie includes a second identifier corresponding to an anonymous user identifier stored in the database, and wherein the anonymous user identifier is associated with second information stored in the database, the second information indicating activities related to interactions of an anonymous user with a second website;
• at least one instruction to correlate the first information and the second information to determine commonalities between the first information and the second information;
• at least one instruction to determine that the registered user and the anonymous user are a single user based on at least one commonality of the commonalities, in response to identifying at least;
• and
• at least one instruction to automatically update the database to include a unified listener identifier (ULID) associating the first information with the second information by linking the registered user identifier with the anonymous user identifier, in response to identifying at least one commonality of the commonalities to.
