Problems solved by technology

[0008] However, the technique disclosed in Japanese Patent Laid-Open No. 2007-21810 requires a specific image forming device and an information processing device compatible therewith, which limits the ability to The scope of the device for which restricted access is provided
Moreover, the technology disclosed in Japanese Patent Laid-Open No. 2007-21810 is designed such that access to a device is permitted or not permitted on a device-by-device basis without identifying a user who will access the device, so there is an unauthenticated User concerns about accessing the device

Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail with reference to the accompanying drawings showing embodiments of the invention.

[0025] figure 1 is a block diagram of an image forming apparatus according to an embodiment of the present invention.

[0026] Such as figure 1 As shown, the image forming apparatus according to the present embodiment is realized by a multifunction machine having a user authentication function, and prints an image by receiving a print instruction from an information processing apparatus directly connected thereto.

[0027] The image forming apparatus includes a controller 101 for controlling the overall operation of the apparatus and a communication interface 102 via which the controller 101 communicates with the outside of the image forming apparatus. The communication interface 102 may be, for example, a USB interface, an Ethernet (registered trademark) interface, or an IEEE1284 interface or any other suitable communicati...

Abstract

An image forming apparatus which makes it possible to provide restricted access thereto without requiring an information processing apparatus to have a special authentication function. The image forming apparatus receives authentication information input by a user using a user interface, and receives a connection request transmitted from the information processing apparatus. When receiving the connection request, the image forming apparatus determines whether or not the user has been authenticated based on the received authentication information. If the user has been authenticated, the image forming apparatus permits execution of processing from the information processing apparatus thereto, whereas if not, it refuses execution of processing from the information processing apparatus.

Description

technical field [0001] The present invention relates to an image forming apparatus having a function of providing a restriction of user access thereto, a control method of the image forming apparatus, and a storage medium. Background technique [0002] Recently, image forming apparatuses have begun to be provided with an access restriction function for the purpose of security and cost management (see, for example, Japanese Patent Laid-Open No. 2007-21810). Although there are various methods of restricting access to an image forming apparatus, the general guideline thereof is to authenticate a user who will access the image forming apparatus, and to permit the user to access the image forming apparatus only after the user is properly authenticated. [0003] In addition, information processing devices and image forming devices such as digital cameras have recently begun to be equipped with functions that enable the information processing device to be directly connected to the ...
