Systems and methods for use in computer network security

A system for use in managing certain data across a network based on multiple keys assigned to different participants in association with the certain data, the system comprising an originating party computing device having a memory and a processor coupled to the memory, the processor configured, by executable instructions stored in the memory of the originating party computing device, to:

• receive, from an originating party, an indication of a relying party in connection with an identification interaction of the originating party to the relying party;
• encrypt data based on a secret, the data including identifying data specific to the originating party;
• generate a key set based on the secret and store the key set in the memory, the key set having at least three keys and structured such that the secret is derivable from at least two of the at least three keys;
• generate a token associated with the originating party, the encrypted data and/or the key set;
• disseminate the token, a first key of the key set, and the encrypted data to a control party;
• and
• disseminate the token and a second key of the key set to the relying party, thereby enabling the relying party to submit a request including the token and the second key to the control party and the control party to identify the first key based on the token and to decrypt the encrypted data disseminated to the control party, using the first and second keys, in order to respond to the request from the relying party.

A non-transitory computer-readable storage media including executable instructions for use in managing certain data across a network based on multiple keys assigned to different participants in association with the certain data, which, when executed by at least one processor, cause the at least one processor to:

• identify a relying party;
• encrypt data based on a secret, the data including identifying data specific to the originating party;
• generate a key set based on the secret and a Shamir secret sharing algorithm, the key set having N keys and structured such that the secret is derivable from at least N−1 of the N keys, where N is an integer greater than 2;
• disseminate a first key of the key set and the encrypted data to a control party;
• and
• disseminate a second key of the key set to the relying party, thereby enabling the relying party to submit a request associated with the data and including the second key to the control party and the control party to decrypt the encrypted data disseminated to the control party, by use of the first and second keys, in order to respond to the request from the relying party.
