Systems and methods relating to digital identities

A system for use in responding to attribute queries related to identifying information for a user, the system comprising:

• an identity host computing device configured to:
• receive a request for an identity code for a user, the user associated with identifying information including multiple attributes;
• in response to the request for the identity code, generate the identity code for the user and transmit the identity code to the user at a communication device associated with the user, wherein the identity code is a one-time code and does not include identifying information of the user;
• receive an identity request from a requesting party including the identity code and at least a first query specific to at least one of the multiple attributes of the user;
• in response to the identity request:
• submit the first query to a first attribute provider;
• receive an attribute response from the first attribute provider;
• compile a response to the identity request received from the requesting party, wherein the response to the identity request includes an answer to the first query, the answer indicative of the at least one of the multiple attributes and based on the attribute response from the first attribute provider, wherein the response to the identity request excludes the at least one of the multiple attributes of the user;
• and
• transmit, to the requesting party, the response to the identity request, thereby permitting the requesting party to be informed about an identity of the user by the answer to the first query, without revealing the identifying information of the user to the requesting party;
• and then in response to at least one subsequent identity request:
• reject a query of one of the at least one subsequent identity request when the query of the one of the at least one subsequent identity request is different than the first query of the identity request, but specific to a same one of the multiple attributes included in the first query of the identity request.

A non-transitory computer readable storage medium including computer-executable instructions for responding to attribute queries related to identifying information for a user, which, when executed by at least one processor of an identity host computing device, cause the at least one processor to:

• receive a request for an identity code for a user, from a mobile device of the user, the user associated with identifying information and the identifying information including multiple attributes of the user;
• in response to the request for the identity code, generate the identity code for the user and transmit the identity code to the user at the mobile device of the user, thereby permitting the user to present the identity code to a requesting party, and wherein the identity code is a one-time code and does not include identifying information of the user;
• receive an identity request from the requesting party, the identity request including the identity code and a first query related to identifying information associated with the user;
• and
• in response to the identity request:
• submit the first query to a first attribute provider having at least a portion of the identifying information for the user, where the at least a portion of the identifying information is indicative of an answer to the first query;
• and
• compile, and transmit to the requesting party, a response to the identity request, the response including the answer to the first query based on an attribute response from the first attribute provider, wherein the response to the identity request excludes the portion of the identifying information indicative of the answer to the first query, thereby permitting the requesting party to be informed about the identity of the user by the answer to the first query, without revealing the identifying information of the user to the requesting party;
• and then
• in response to at least one subsequent identity request, reject a query of the at least one subsequent identity request based on an input from the user and/or when the query of the at least one subsequent identity request is different than the first query of the identity request but is related to a same portion of identifying information included in the first query of the identity request.
