Image forming apparatus, mobile terminal, and method for processing local login of apparatuses

1. A local login processing method of an image forming apparatus, the local login processing method comprising:

generating session information according to a remote login request upon receiving the remote login request from a mobile terminal;

transmitting the session information to the mobile terminal;

receiving, from the mobile terminal, a local login request comprising local login information generated by using at least some of the session information; and

approving the local login request by comparing the session information and the local login information,

wherein the local login information comprises a session identification (ID) included in the session information or a personal identification number (PIN) code generated based on the session information, and

wherein, when the local login information comprises the PIN code, the approving of the local login request based on the session information comprises:

generating a PIN code based on the session information; and

approving the local login request when the generated PIN code and the PIN code comprised in the local login information match each other.

2. The local login processing method of claim 1 , wherein the approving of the local login request by comparing the session information and the local login information comprises approving the local login request by comparing the session information and the at least some of the session information comprised in the local login information.

3. The local login processing method of claim 1 ,

wherein the receiving, from the mobile terminal, of the local login request comprising the local login information generated by using the at least some of the session information comprises:

receiving a personal identification number (PIN) code issue request from the mobile terminal;

generating a PIN code based on the session information and transmitting the PIN code to the mobile terminal; and

receiving a PIN code through an input and output unit, and

wherein the approving of the local login request by comparing the session information and the local login information comprises approving the local login request when the PIN code transmitted to the mobile terminal and the received PIN code match each other.

4. The local login processing method of claim 1 , further comprising:

receiving, from the mobile terminal, job setting information, and storing the job setting information;

when the local login request is approved, applying the stored job setting information based on the local login information; and

displaying a job setting state to which the stored job setting information is applied.

5. An image forming apparatus comprising:

an input and output unit;

a communicator to transmit and receive data to and from a mobile terminal;

a memory to store a program for a local login process; and

a controller to:

execute the program for the local login process to generate session information according to a remote login request upon receiving the remote login request from the mobile terminal,

transmit the session information to the mobile terminal,

receive, from the mobile terminal, a local login request comprising local login information generated by using at least some of the session information,

approve the local login request by comparing the session information and the local login information, and

control to perform an image forming job,

wherein the local login information comprises a session identification (ID) included in the session information or a personal identification number (PIN) code generated based on the session information, and

wherein, when the local login information comprises the PIN code, the controller generates a PIN code based on the session information, and approves the local login request when the generated PIN code and the PIN code comprised in the local login information match each other.

6. The image forming apparatus of claim 5 , wherein the controller approves the local login request by comparing the session information and the at least some of the session information comprised in the local login information.

7. The image forming apparatus of claim 5 , wherein the controller:

receives a personal identification number (PIN) code issue request from the mobile terminal,

generates a PIN code based on the session information and transmits the PIN code to the mobile terminal,

receives a PIN code through the input and output unit, and

approves the local login request when the PIN code transmitted to the mobile terminal and the received PIN code match each other.

8. The image forming apparatus of claim 5 , wherein the controller:

receives, from the mobile terminal, job setting information, and stores the job setting information, when the local login request is approved,

applies the stored job setting information based on the local login information, and

displays a job setting state to which the stored job setting information is applied on the input and output unit.

9. A local login processing method of a mobile terminal, the local login processing method comprising:

receiving user information from a user;

requesting an image forming apparatus to undertake remote login based on the user information;

receiving and storing session information from the image forming apparatus;

generating local login information based on at least some of the session information; and

requesting the image forming apparatus to undertake local login based on the local login information,

wherein the generating of the local login information based on the at least some of the session information comprises:

generating the local login information based on session identification (ID) included in the session information: or

generating a personal identification number (PIN) code based on the session information and generating the local login information based on the generated PIN code, and

wherein, when the local login information comprises the PIN code, a PIN code is generated based on the session information, and the local login request is approved when the generated PIN code and the PIN code comprised in the local login information match each other.

10. The local login processing method of claim 9 , further comprising:

receiving a job setting value from the user and storing the job setting value as job setting information; and

transmitting the stored job setting information to the image forming apparatus.
