Abstract

An MFP stores a plurality of different pieces of biometric information of a user and a plurality of secret keys respectively corresponding to the pieces of biometric information in the TPM and registers public keys corresponding to the private keys in a server. When an authentication request is received from the server, the MFP executes a biometric authentication process using the biometric information input from the user and the biometric information registered in the TPM. If authentication is successful in the biometric authentication process, the MFP creates signature data and transmits it to the server. If verification of the signature data using the public key in the server is successful, the MFP performs display related to a shortcut process associates with the biometric information corresponding to the secret key used when the signature data that is a target of the verification is created by an input and output device.

Dependent claims

A system comprising:

an information processing apparatus including;
an authentication module for biometric authentication,
a storage unit having tamper resistance for storing biometric information of a user necessary for performing an authentication process by the authentication module and a secret key created when the biometric information is registered,
a biometric information sensor for reading the biometric information of the user,
a display;
and
a server configured to manage a public key corresponding to the secret key, and configured to be connected to the information processing apparatus through a network,
wherein the information processing apparatus comprises:
a first memory storing instructions;
and
a first processor executing the instructions stored in the first memory causing the information processing apparatus to:
store a plurality of different pieces of biometric information of the user and a plurality of secret keys respectively corresponding to the pieces of biometric information in the storage unit to register the public keys corresponding to the plurality of secret keys in the server;
execute a biometric authentication process by the authentication module using the biometric information input from the user through the biometric information sensor and the biometric information registered in the storage unit in a case where an authentication request is received from the server;
create signature data using the secret key corresponding to the biometric information used in the biometric authentication process registered in the storage unit and a parameter included in the authentication request in a case where the authentication is successful in the biometric authentication process;
and
transmit the created signature data to the server, and
wherein the server comprises:
a second memory storing instructions;
and
a second processor executing the instructions stored in the second memory causing the server to perform verification of the signature data transmitted from the information processing apparatus using the public key managed by the server, based on the authentication request, and
wherein instructions stored in the first memory further cause the information processing apparatus to make the display perform displaying related to execution of a process associated with the biometric information corresponding to the secret key used when the signature data that is a target of the verification is created in a case where the verification by the server is successful.

making the display perform displaying related to execution of a process associated with the biometric information corresponding to the secret key used when the signature data that is a target of the verification is created in a case where the verification by the server is successful, by the information processing apparatus.

13 more elements

An information processing apparatus comprising:

an authentication module for biometric authentication,
a storage unit having tamper resistance for storing biometric information of a user necessary for performing an authentication process by the authentication module,
a biometric information sensor for reading the biometric information of the user,
a display,
a memory storing instructions;
and
a processor executing the instructions stored in the memory causing the information processing apparatus to:
