Homomorphic technology

A device comprising:

• a non-transitory memory for storing an application, the application configured for:
• querying homomorphic encrypted information based on current acquired user information, wherein a query receives the current acquired user information as input, determines if a match is found in the homomorphic encrypted information without exposing the homomorphic encrypted information, and returns a result indicating the match being found or not;
• maintaining or increasing a user's trust score when the match is found in the homomorphic encrypted information;
• and
• decreasing a user's trust score when the match is not found in the homomorphic encrypted information;
• and
• a processor configured for processing the application.

A method programmed in a non-transitory memory of a device comprising:

• acquiring user information;
• and
• encrypting the user information using homomorphic encryption to be stored as homomorphic encrypted information, wherein a query receives the current acquired user information as input, determines if a match is found in the homomorphic encrypted information without exposing the homomorphic encrypted information, and returns a result indicating the match being found or not;
• querying the homomorphic encrypted information based on current acquired user information;
• maintaining or increasing a user's trust score when the match is found in the homomorphic encrypted information;
• and
• decreasing a user's trust score when the match is not found in the homomorphic encrypted information.
