Systems and methods for matching online users across devices

A system for associating a plurality of internet-enabled devices with a common user profile over a network, the method comprising:

• a data storage device storing instructions and a processor implementing instructions for associating a plurality of internet-enabled devices with a common user profile for targeting electronic content;
• receiving, from a plurality of internet-enabled devices, requests for electronic content, the requests including a unique identifier or instance identifier for a first user device corresponding to a common user;
• for a first source IP address for which request for electronic content were received over a predetermined time period, identifying at least one pair of devices comprising a first user device and a second user device from which requests were received;
• determining that the first user device and the second user device are operated by the common user based on whether the at least one pair of devices has been identified for a second source IP address over the predetermined time period;
• for a determined common owner operating the first and second user devices, receiving, based on the unique identifier or instance identifier, a demographic or browsing history information generated from the first user device;
• and
• determining, based on the demographic or browsing history information generated from the first user device, electronic content to transmit to a second user device corresponding to the common user.

A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform a method for associating a plurality of internet-enabled devices with a common user profile over a network, the method comprising:

• a data storage device storing instructions and a processor implementing instructions for associating a plurality of internet-enabled devices with a common user profile for targeting electronic content;
• receiving, from a plurality of internet-enabled devices, requests for electronic content, the requests including a unique identifier or instance identifier for a first user device corresponding to a common user;
• for a first source IP address for which request for electronic content were received over a predetermined time period, identifying at least one pair of devices comprising a first user device and a second user device from which requests were received;
• determining that the first user device and the second user device are operated by the common user based on whether the at least one pair of devices has been identified for a second source IP address over the predetermined time period;
• for a determined common owner operating the first and second user devices, receiving, based on the unique identifier or instance identifier, a demographic or browsing history information generated from the first user device;
• and
• determining, based on the demographic or browsing history information generated from the first user device, electronic content to transmit to a second user device corresponding to the common user.
