Image forming apparatus, control method for image forming apparatus, server, control method for server and storage medium

A control method for an image forming apparatus configured to communicate with a terminal having an authentication function, the control method comprising:

• transmitting, to the terminal, verification data for performing user authentication for the image forming apparatus;
• receiving, from the terminal, signature data obtained by encrypting the verification data using a secret key corresponding to authentication in the authentication function of the terminal, based on execution of the authentication;
• and
• performing verification of the received signature data using the verification data and a public key corresponding to the secret key,
• wherein, in a case where the verification has succeeded, a function that is premised on the user authentication is provided.

A storage medium storing a computer program for executing a control method for an image forming apparatus configured to communicate with a terminal having an authentication function, the control method comprising:

• transmitting, to the terminal, verification data for performing user authentication for the image forming apparatus;
• receiving, from the terminal, signature data obtained by encrypting the verification data using a secret key corresponding to authentication in the authentication function of the terminal, based on execution of the authentication;
• and
• performing verification of the received signature data using the verification data and a public key corresponding to the secret key,
• wherein, in a case where the verification has succeeded, a function that is premised on the user authentication is provided.

A server configured to communicate with an image forming apparatus and a terminal, the server comprising:

• at least one memory storing at least one program;
• and
• at least one processor,
• wherein the at least one processor reads the at least one program from the at least one memory and executes the at least one program to cause the sever to:
• receive, from the terminal, identification information on the image forming apparatus;
• receive, from the terminal, signature data obtained by encrypting verification data for performing user authentication for the image forming apparatus, and perform verification of the signature data;
• and
• transmit, based on a success of the verification, an instruction to execute login processing for a user authenticated by the user authentication to the image forming apparatus identified based on the identification information,
• wherein the login processing for the user is executed on the image forming apparatus in accordance with the instruction.

A control method for a server configured to communicate with an image forming apparatus and a terminal, the control method comprising:

• receiving, from the terminal, identification information on the image forming apparatus;
• receiving, from the terminal, signature data obtained by encrypting verification data for performing user authentication for the image forming apparatus and performing verification of the signature data;
• and
• transmitting, based on a success of the verification, an instruction to execute login processing for a user authenticated by the user authentication to the image forming apparatus identified based on the identification information,
• wherein the login processing for the user is executed on the image forming apparatus in accordance with the instruction.
