Abstract
An authentication method and system provides for a user requesting authentication where the authentication request includes Personally Identifiable Information (PPI) such as geolocation data. The user's device requesting authentication alters or encrypts the PII in order to prevent the PII's unintentional discovery by third parties or to comply with jurisdictional requirements for the safeguarding of PII. The receiving party saves the altered or encrypted PII for later use. In order to use the PII and perform calculations for authentication, the receiving party requests a trusted third party with knowledge of the methodology or key used to alter or encrypt the PII to perform calculations on the original values of the PII without saving the PII. The trusted third party returns a computed value to the receiving party where it is used to determine whether the user will be authenticated.
