Identity-linked device information for user identification and transaction personalization via mobile tagging

A computer-implemented method for validating user identity-linked device information and providing a user identifier associated with the identity-linked device information for transaction personalization, the method comprising:

• receiving, via a carrier network, at the user identification and personalization system from a user device, an electronic data transmission, the electronic data transmission comprising identity-linked device information, the carrier network comprising at least a carrier device, the carrier device configured to inject the electronic data transmission with identity-linked device information via a header enrichment process, wherein the electronic data transmission is indicative of prior execution, by the user device identified by the identity-linked device information, of an access link having been detected and decoded from a decodable visual representation and having caused the user device to execute the access link;
• determining a user identifier based on the identity-linked device information;
• and
• transmitting, to the user device, an authentication indication comprising at least the user identifier, the authentication indication configured to cause the user device to forward the user identifier to a service provider device.

A computer program product for validating user identity based on identity-linked device information and providing a user identifier associated with the identity-linked device information for transaction personalization, the computer program product comprising a non-transitory computer readable storage medium having computer program instructions stored therein, the computer program instructions configured to, when executed by a processor, cause the processor to:

• receive, via a carrier network, at the user identification and personalization system from a user device, an electronic data transmission, the electronic data transmission comprising identity-linked device information, the carrier network comprising at least a carrier device, the carrier device configured to inject the electronic data transmission with identity-linked device information via a header enrichment process, wherein the electronic data transmission is indicative of prior execution, by the user device identified by the identity-linked device information, of an access link having been detected and decoded from a decodable visual representation and having caused the user device to execute the access link;
• determine a user identifier based on the identity-linked device information;
• and
• transmit, to the user device, an authentication indication comprising at least the user identifier, the authentication indication configured to cause the user device to forward the user identifier to a service provider device.
