Abstract

A system for verifying information associated with a user can include at least three devices. The first device is configured to transmit, to the second device, user-associated information, a unique identifier associated with the user-associated information and an identity digital signature generated using an identity private key associated with the user and a message comprising a previously determined hash of a portion of the user-associated information combined with the unique identifier. The second device is configured to generate the hash of the portion of the user-associated information combined with the unique identifier and transmit the generated hash and the identity digital signature to the third device. The third device is configured to lookup the generated hash in a database, verify the identity digital signature using the identity public key related to the generated hash in the database, and upon successful verification, transmit a success response to the second device.

Claims15

Dependent claims

A system for verifying information associated with a user, comprising a first information processing device, a second information processing device and a third information processing device, wherein:

the first information processing device is configured to transmit to the second information processing device:
a first message comprising information associated with the user, a unique identifier uniquely associated with the user associated information and an identity digital signature generated using an identity private key of an identity private key and identity public key pair associated with the user and a message generated using a portion of the first message;
the second information processing device is configured to generate a hash of a portion of the user associated information combined with the unique identifier associated with the user associated information and transmit, to the third information processing device, a second message comprising the generated hash, the identity digital signature and the portion of the first message based on which the identity digital signature is generated;
and
the third information processing device is configured:
to lookup the generated hash in a database relating a previously determined hash of the portion of the user associated information combined with the unique identifier associated with the user associated information with the identity public key of the identity private key and identity public key pair associated with the user,
to verify the identity digital signature using the identity public key related to the generated hash in the database, and
upon successful verification of the identity digital signature, to transmit a response to the second information processing device indicating the successful verification.

5 more elements

A second information processing device for use in a system for verifying information associated with a user, wherein the second information processing device comprises circuitry configured:

to receive, from a first information processing device, a first message comprising information associated with the user, a unique identifier uniquely associated with the user associated information and an identity digital signature generated using an identity private key of an identity private key and identity public key pair associated with the user and a message generated using a portion of the first message;
to generate a hash of a portion of the user associated information combined with the unique identifier associated with the user associated information and transmit, to a third information processing device, a second message comprising the generated hash, the identity digital signature and the portion of the first message digitally signed with the identity digital signature;
and
to receive a response, from the third information processing device, indicating a successful verification of the identity digital signature.
