An image forming apparatus includes a signature verification unit, an execution propriety determination unit, an image forming unit, and a control unit. The signature verification unit decrypts encrypted data with a preset public key in accordance with acquisition of the encrypted data, and uses the decrypted data to verify a digital signature representing authenticity and integrity of a program contained in the decrypted data; the execution propriety determination unit permits execution of a program registered in a preset permission list and the program in which digital signature is verified; the image forming unit forms an image on an image forming medium; and the control unit controls the image forming unit by executing the program permitted to be executed.

A management device performs any one of first processing where an image forming apparatus whose operation set as a mode transfer operation is the same as an unauthorized operation detecting image forming apparatus is made to change the presently set mode transfer operation, second processing where image forming apparatuses which belong to a group that the unauthorized operation detecting image forming apparatus belongs to are made to change the presently set mode transfer operation and third processing where the image forming apparatuses which belong to the group that the unauthorized operation detecting image forming apparatus belongs to are prevented from being transferred to a maintenance mode.

Management system, management device and image forming apparatus

An embedded system includes a nonvolatile memory, a control section, and a firmware update section. The nonvolatile memory stores firmware and a public key in a normal area, and stores a hash value concerning the public key in an access restricted area. The control section reads and executes the firmware from the nonvolatile memory. The firmware update section receives new firmware in which the hash value is encrypted and given as an electronic signature, and updates the firmware to the new firmware. The firmware update section is configured to: read the public key from the nonvolatile memory to calculate the hash value concerning the public key; when the hash value is identical to the hash value stored in the nonvolatile memory, calculate a hash value of the new firmware; decrypt the electronic signature with the public key to restore the hash value; and when these hash values are identical to each other, update the firmware.

Embedded system, information processing unit, and image forming apparatus

A PC includes a part designation receiving section which receives a designation of a display object part to be displayed in a display screen image, a layout instruction receiving section which receives a layout instruction of the display object part, an action setting section which sets an action associated with the display object part, and a creating section which creates screen image data of the display screen image.

Image forming apparatus and display control device

An information processing device has a parts selection instruction receiving portion that receives from an operator a selection instruction of display object parts to be displayed on a screen for receiving an instruction from an operator. A job selection instruction receiving portion receives from an operator a selection instruction of a job that is executable by an electrical device and is associated with the display object parts indicated by the display object parts selection instruction. An external service selection instruction receiving portion receives from an operator a selection instruction of a service executable by an external device other than the electrical device and associated with the display object parts indicated by the display object parts selection instruction. A screen data generation portion generates screen data of the display screen based on content determined by the parts selection instruction, the job selection instruction, and the service selection instruction.

Information processing device, computer-readable recording medium on which operational control program is recorded, electrical device, and operational control system

An electronic apparatus includes a security storage unit, a security information acquisition unit, a calculation unit, a determination unit, a notification unit, and an operation control unit. The security storage unit is configured to store a plurality of securities together with respective security levels associated with the securities. The security information acquisition unit is configured to acquire security information concerning the apparatus. The calculation unit is configured to calculate a total of the security level or levels of the security or securities applied to the apparatus, using the security levels of the securities stored in the security storage unit. The determination unit is configured to determine whether or not the calculated total has reached a predetermined threshold.

Electronic apparatus, image forming apparatus, and security level management method

An image forming apparatus to be network-connected is provided with an acquirer for requesting event information indicating a specific event having occurred in another image forming apparatus via a network and acquiring the event information transmitted via the network in response to this request, and a processor for performing a predetermined process to deal with the specific event when the event information is acquired by the acquirer.

Image forming apparatus and image forming system

It is determined whether management information exists in an erasure folder or not after a power of an image forming apparatus is turned on. When the management information exists, image data is erased based on information of the management information. Then, it is determined whether the power is turned off or not during the erasing operation, and when it is determined that the power is turned off, the erasing operation of the image data is stopped and the management information remains in the erasure folder, but when it is determined that the power is not turned off, the erasing operation of the image data is completed.
