A communication system comprising an information processing apparatus and a mobile terminal, wherein when the mobile terminal receives a packet transmitted from the information processing apparatus, it determines whether or not a login condition for transmitting a login request is satisfied based on a received signal strength of the packet, and it transmits the login request to the information processing apparatus in a case where it determines that the login condition is satisfied, and does not transmit the login request to the information processing apparatus in a case where it is determines that the login condition is not satisfied.

To maintain confidentiality by a simile authentication procedure. An image processing device includes an input receiver configured to receive an input of an authentication pattern that is a trajectory of contact coordinates indicating a contact position on an operation unit; and a concatenation image display unit configured to display an image connecting, out of a plurality of predetermined images that are displayed on the operation unit, a part of the predetermined images that includes a first predetermined image and a second predetermined image of the predetermined images that are connected by the trajectory, wherein, prior to a display area of the first predetermined image overlapping the contact coordinates, a display area of the second predetermined image overlaps the contact coordinates.

A communication system comprising an information processing apparatus and a mobile terminal, wherein when the mobile terminal receives a packet transmitted from the information processing apparatus, it determines whether or not a login condition for transmitting a login request is satisfied based on a received signal strength of the packet, and it transmits the login request to the information processing apparatus in a case where it determines that the login condition is satisfied, and does not transmit the login request to the information processing apparatus in a case where it is determines that the login condition is not satisfied.

An information processing apparatus having an image processing function is provided that includes a memory storing a program and a processor configured to execute the program to implement processes of accepting an input of server information for establishing connection with a server apparatus that is connected to the information processing apparatus via a network, determining whether the accepted server information is valid, generating connection destination information including the accepted server information that has been determined to be valid and registering the generated connection destination information, and transmitting a processing result of the image processing function to the server apparatus using the registered connection destination information.

An image processing apparatus includes a request determining unit receiving an operation event indicating a request to use an image processing function and determining whether the request is from a guest user based on the received operation event; a guest login processing unit generating guest login information including a guest user identifier and access right information of the guest user if the request is from the guest user and sending a login request to request a login process for the guest user based on the guest login information; an access control unit disabling access control on the image processing function in response to the login request based on the access right information in the guest login information; and a usage history recording unit recording a usage history of the image processing function in association with the guest user based on the guest user identifier in the guest login information.

It is made possible to print an image stored in an image processing apparatus by a printing apparatus without requiring a complicated operation. By a printing apparatus operating as a first access point by fixed authentication information, in the case where the communication is controlled in a first mode for performing a wireless LAN connection with an image processing apparatus storing the fixed authentication information, a beacon signal including a specific SSID included in the fixed authentication information is transmitted, and in the case where the image processing apparatus receives printing instructions, a connection without intervention of a second access point different from the printing apparatus and the image processing apparatus is established with the printing apparatus by using the fixed authentication information and an image to be printed is transmitted to the printing apparatus on a condition that a beacon signal including the specific SSID is detected.

An image forming apparatus including applications and system side software for providing system side services to the applications is provided, in which the image forming apparatus includes: an authentication module for displaying an authentication screen on an operation panel of the image forming apparatus, wherein the authentication module allows the image forming apparatus to display a screen for using the image forming apparatus instead of the authentication screen if authentication data input from the authentication screen satisfies an authentication condition, and wherein the authentication module is provided in the image forming apparatus separately from the system side software.

A mobile terminal that communicates with an image processing apparatus including a scanning function includes a display unit that displays a screen, a first instruction unit that, when the display unit displays a specific screen corresponding to the scanning function, instructs the image processing apparatus to activate a specific application corresponding to the scanning function, and a second instruction unit that, when the mobile terminal receives an instruction to perform the scanning function, instructs the image processing apparatus to perform the scanning function.

An image forming apparatus includes at least one first processor and at least one first memory coupled to the first processor and having stored thereon instructions, when executed by the first processor, and cooperating to act as a determination unit configured to determine whether a password set to the image forming apparatus is an initial password, a lock function setting unit configured to enable a lock function preventing the setting of the image forming apparatus from being changed with an operation unit or an operation screen of the image forming apparatus, and a control unit configured to perform control so that a screen of a setting to operate the image forming apparatus via a client terminal is not displayed in response to the password being the initial password as the password.

Provided is an electronic apparatus (EA) and a user authentication method thereof both can prevent information leakage and disadvantages caused by an unauthorized access to the EA. The EA is configured to store a combination of a recognizing-code and a key-code correlated therewith, the combination being in relationship with each of plural users, and to give a user an exclusive authority for executing a specific process if an inputted combination of a recognizing-code and a key-code=the stored combination of the recognizing-code and the key-code. In case of a request for accepting the specific process, if the inputted combination of the recognizing-code and the key-code is≠the stored combination of the recognizing-code and the key-code, the EA notifies, without executing the specific process, initiating a receipt of instructing the specific process to user of the inputted combination.
