Method and system for verifying user authorization using zero-proof verification

A method for evaluating eligibility, the method comprising:

• receive, from a computing node associated with a user, a first request to determine eligibility of the user to perform a data interaction;
• in response to receiving the first request, prompt the user to provide eligibility information associated with the user, wherein the user is eligible to perform the data interaction when the eligibility information associated with the user satisfies an eligibility criteria;
• receive the eligibility information;
• determine an eligibility result by inputting the eligibility information into an evaluation algorithm, wherein:
• the evaluation algorithm is configured to determine eligibility for performing the data interaction based on the eligibility criteria;
• and
• the eligibility result indicates the eligibility of the user to perform the data interaction based on the eligibility criteria;
• in response to determining that the user is eligible to perform the data interaction, transmit an indication of the eligibility to the computing node;
• generate a zero-knowledge proof of the eligibility of the user to perform the data interaction, wherein the zero-knowledge proof does not include the received eligibility information;
• verify the zero-knowledge proof of the eligibility of the user to perform the data interaction by running a verification algorithm;
• in response to determining that the zero-knowledge proof is valid, initiate the data interaction requested by the user.

A non-transitory computer-readable medium storing instructions that when executed by a processor causes the processor to:

• receive, from a computing node associated with a user, a first request to determine eligibility of the user to perform a data interaction;
• in response to receiving the first request, prompt the user to provide eligibility information associated with the user, wherein the user is eligible to perform the data interaction when the eligibility information associated with the user satisfies an eligibility criteria;
• receive the eligibility information;
• determine an eligibility result by inputting the eligibility information into an evaluation algorithm, wherein:
• the evaluation algorithm is configured to determine eligibility for performing the data interaction based on the eligibility criteria;
• and
• the eligibility result indicates the eligibility of the user to perform the data interaction based on the eligibility criteria;
• in response to determining that the user is eligible to perform the data interaction, transmit an indication of the eligibility to the computing node;
• generate a zero-knowledge proof of the eligibility of the user to perform the data interaction, wherein the zero-knowledge proof does not include the received eligibility information;
• verify the zero-knowledge proof of the eligibility of the user to perform the data interaction by running a verification algorithm;
• in response to determining that the zero-knowledge proof is valid, initiate the data interaction requested by the user.
