Biometric based self-sovereign information management based on reverse information search

Machine readable and non-transitory medium having information recorded thereon for authenticating a user, wherein the information, when read by the machine, causes the machine to perform the following:

• receiving a first request to set up authentication information with respect to a user, wherein the authentication information specifies a type of biometric information to be used for future authentication of the user;
• performing, in response to receiving the first request, a reverse information search by:
• searching biometric information related to the user from at least one publicly accessible source, and
• determining that the searched biometric information comprises the type of biometric information to be used for future authentication of the user;
• making a decision with the respect to the first request based on the searched biometric information in terms of whether the searched biometric information includes adequate information to enable generation of fraudulent biometric authentication information;
• receiving a second request from a person for authenticating that the person is the user, wherein the second request includes the type of biometric information submitted by the person for the authentication;
• determining whether the type of biometric information is a valid type of information for authenticating the user based on the reverse information search result;
• and
• rejecting the person to be the user if the type of biometric information submitted by the person is not a valid type of information for authenticating the user.

A system for authenticating a user, comprising:

• an authentication information set up computer hardware configured for receiving a first request to set up authentication information with respect to a user, wherein the authentication information specifies a type of biometric information to be used for future authentication of the user;
• and
• an authentication configuration computer hardware configured for
