An information processing apparatus includes a selection unit configured to select an item to be used for a password from among items written on a formatted document, a generation unit configured to generate a password based on a character string obtained as a character recognition result for the item selected by the selection unit on the formatted document, a conversion unit configured to convert document data obtained by reading the formatted document into document data protected with the password, and a setting unit configured to set information for identifying the item used for generation of the password as attribute information of the protected document data.

In an image forming apparatus that cooperates with a management service and a blockchain service, the management service receiving a document via a network and storing the document, and the blockchain service managing information on the document in block units, defining a relation between each of a plurality of blocks and blocks before and/or after the block, and managing the plurality of blocks using a plurality of nodes. In a case where an error occurs during printing of the document, new information to be registered in response to completion of the printing of the document is not registered in the blockchain service, the printing is stopped, and an error process is performed.

An information processing apparatus includes a setting unit, a detector and a controller. The setting unit sets setting information associating a registered image obtained by reading an image with control information indicating whether input image data is to be stored or not. The detector detects the registered image from the input image data. The controller controls whether or not the input image data including the registered image is stored in a storage based on the setting information.

An information processing system includes a registration unit and a controller. The registration unit registers prohibited information associated with at least one of pieces of attribute information on a per piece-of-attribute information basis. The controller refers to the pieces of attribute information and the prohibited information. The controller performs error handling if received image information includes the prohibited information associated with a piece of attribute information assigned to the image information.

An image reading apparatus includes a manuscript reader, a communication device, a distance determination device, a manuscript leaving determination device, a controller, and an approaching person determination device. The manuscript leaving determination device determines whether a manuscript is left in the image reading apparatus. The communication device performs wireless communication with a portable device carried by a user. The approaching person determination device determines presence and absence of a person approaching the image reading apparatus. The controller transmits, to the portable device, warning information indicating a risk of information leakage when the distance determination device determines that a distance between the image reading device and the portable device has reached a predetermined first threshold value and the approaching person determination device determines that there is an approaching person in a state in which the manuscript leaving determination device has determined that a manuscript is left in the image reading apparatus.

An image processing apparatus includes an image reading unit that reads an image of an original document, an image processing unit that processes image data of the image read by the image reading unit, and a suspension unit that suspends, if a predetermined pattern has been detected from the image read by the image reading unit, the image processing unit in an operation of processing the image data until the original document is removed from the image reading unit.

An information processing system includes a registration unit and a controller. The registration unit registers prohibited information associated with at least one of pieces of attribute information on a per piece-of-attribute information basis. The controller refers to the pieces of attribute information and the prohibited information. The controller performs error handling if received image information includes the prohibited information associated with a piece of attribute information assigned to the image information.

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.

An information processing apparatus includes a reception unit that receives a transmission request for image data from an image processing apparatus to which a user provides an instruction to execute image processing, an acquisition unit that acquires a security policy corresponding to attribute information related to an attribute of the image processing apparatus in a case where the reception unit receives the transmission request, and a control unit that performs control for transmitting the image data to the image processing apparatus and executing the image processing in the image processing apparatus in accordance with the security policy acquired by the acquisition unit.

An image processing apparatus including a processor that performs: compressing target data for printing; decompressing the compressed target data; and when the resolution of the uncompressed target data is higher than the resolution of low-resolution data included in the compressed target data, generating sample data by decompressing only the low-resolution data, the sample data to be used for a process of detecting data of a particular image from the target data.
