Targeted user access control system

A computer program product comprising a non-transitory computer-readable storage medium embodied with computer program instructions that when executed by a computer cause the computer to implement:

• initiating creation of a single-use targeted link that provides access to a restricted access data entry system;
• serving the single-use targeted link through the network interface to a computer system of a targeted user with a time validity constraint;
• verifying that an access request received at the restricted access data entry system through the single-use targeted link is received within the time validity constraint;
• monitoring network traffic volume received through the single-use targeted link at the network interface;
• applying a network traffic throttling control to reduce the network traffic volume received through the single-use targeted link based on determining that the network traffic volume exceeds a traffic volume threshold, wherein the network throttling control comprises:
• locking an incentive identifier key in a coherency cache associated with an instance of the single-use targeted link based on verifying that the access request received at the restricted access data entry system through the single-use targeted link is received within the time validity constraint;
• retrieving a throttle value as a count associated with the incentive identifier key from the coherency cache;
• updating the count in the coherency cache;
• comparing the updated count indicative of the network traffic volume to the traffic volume threshold;
• and
• unlocking the incentive identifier key in the coherency cache responsive to comparing the updated count to the traffic volume threshold;
• and
• applying an identity control at the restricted access data entry system to confirm entry of at least one identifying characteristic that matches the targeted user.

A system, comprising:

• a network interface operable to interact with a plurality of computer systems through one or more network connections;
• at least one processing device;
• and
• at least one memory device in communication with the at least one processing device, the at least one memory device storing instructions that when executed by the at least one processing device result in:
• initiating creation of a single-use targeted link that provides access to a restricted access data entry system, wherein the single-use targeted link comprises a base uniform resource locator, a generated user identifier, a timestamp, a checksum, and an incentive identifier appended together and hashed;
• serving the single-use targeted link through the network interface to a computer system of a targeted user with a time validity constraint;
• verifying that an access request received at the restricted access data entry system through the single-use targeted link is received within the time validity constraint;
• monitoring network traffic volume received through the single-use targeted link at the network interface;
• applying a network traffic throttling control to reduce the network traffic volume received through the single-use targeted link based on determining that the network traffic volume exceeds a traffic volume threshold;
• and
• applying an identity control at the restricted access data entry system to confirm entry of at least one identifying characteristic that matches the targeted user.
