System, method, and recording medium for preventing back propogation of data protection

A data protection method, comprising:

• receiving a service request from a user and receiving pre-approved versions of content from a provider;
• matching a pre-approved version of content of the pre-approved versions of content to the user based on a condition of the user;
• receiving user data to complete the pre-approved version of the content;
• and
• executing a program using zero-knowledge verifiable computing to remove private content from the pre-approved version of the content to ensure privacy of the condition of the user from the provider,
• wherein the user data is received via a third party intermediary that exchanges data between the user and the provider and that is separate from the user and the provider,
• wherein herein the zero-knowledge verifiable computing comprises a technique that is able to ensure the privacy of the user data from the party receiving it, and
• wherein the zero-knowledge verifiable computing circuit carries out the zero-knowledge verifiable computing based on combinatorial logic with the completed pre-approved version of the content using a zero-knowledge protocol.

A data protection system for exchanging private data between a user and a provider, the system comprising:

• a content matching circuit configured to match a pre-approved version of content of pre-approved versions of content to the user based on a condition of the user, and to send the matched pre-approved version of content to a first device for the user to complete the matched pre-approved version of content;
• and
• a zero-knowledge verifiable computing circuit configured to execute a program using zero-knowledge verifiable computing to remove private content from the pre-approved version of the content completed by the user, to ensure privacy of the condition of the user from the provider,
• wherein the user data is received via a third party intermediary that exchanges data between the user and the provider and that is separate from the user and the provider,
• wherein herein the zero-knowledge verifiable computing comprises a technique that is able to ensure the privacy of the user data from the party receiving it, and
• wherein the zero-knowledge verifiable computing circuit carries out the zero-knowledge verifiable computing based on combinatorial logic with the completed pre-approved version of the content using a zero-knowledge protocol.
