Integrating identity tokens and privacy-preserving identity attribute attestations into interactions

An identity network computer comprising:

• a processor;
• and
• a non-transitory computer readable medium comprising instructions executable by the processor to perform operations including:
• receiving, by the identity network computer, a query set comprising a plurality of test identity attributes;
• retrieving, by the identity network computer, one or more derivatives of one or more identity attributes associated with a user, and an encrypted trapdoor;
• computing, by the identity network computer, an obscured query set using the query set, and the one or more derivatives of the one or more identity attributes associated with the user;
• and
• transmitting, by the identity network computer, the obscured query set and the encrypted trapdoor to a user device associated with the user, which transmits a first modified trapdoor and the obscured query set to a relying party computer,
• wherein the relying party computer uses the obscured query set, and the first modified trapdoor, to determine if the one or more the identity attributes of the one or more derivatives of the identity attributes is a member of the query set associated with the obscured query set.
