Abstract: An object of the present disclosure is to enable a warning to be issued to a person who is highly likely to be put in danger at a risky point. In an information processing apparatus, a controller acquires information indicating a risky point, acquires a state of a person with a predetermined positional relationship to the risky point, and determines whether or not the state of the person is a state where there is a high possibility of being put in danger, among a plurality of states of the person assumable at the risky point. Furthermore, in a case where the state of the person is determined to be the state where there is a high possibility of being put in danger, the controller causes an output unit to output information indicating a warning.

Abstract: An information processing system includes a first information processing apparatus and a second information processing apparatus. The first information processing apparatus includes first circuitry. The first circuitry generates signature data for an update file based on a hash value obtained based on the update file and provide the update file. The second information processing apparatus includes second circuitry. The second circuitry obtains the update file and the signature data, verifies the update file with the signature data in updating a start-up file for the second information processing apparatus with the update file, updates the start-up file with the verified update file, generates, based on the hash value obtained based on the signature data, verification data for verifying the updated start-up file, and verifies the updated start-up file with the verification data in starting up the second information processing apparatus with the updated start-up file.

Abstract: An information processing apparatus, an information processing method, and a non-transitory recording medium. The information processing apparatus creates in one or more memories, a partition in a verification target area for verifying integrity and authenticity and a partition in a non-verification target area for not verifying the integrity and authenticity, stores a compressed file and authentication data created from the compressed file in the partition in the verification target area of one or more memories, verifies a signature of the compressed file using the compressed file and the authentication data stored in the partition in the verification target area of the one or more memories, and based on a successful result of the signature verification, decompresses, and expands the compressed file to the partition in the non-verification target area of the one or more memories.

Abstract: An information processing apparatus includes processing circuitry configured to perform signature verification based on a value and a signature file to ensure integrity and authenticity of an update file to be used when a system is updated, the value being uniquely calculated based on the update file, and the signature file corresponding to the update file; and ensure the integrity and authenticity of an invocation file to be executed at startup of the system. After the system is updated using the update file for which the integrity and authenticity are ensured, the processing circuitry is configured to cause the system to be launched using the invocation file for which the integrity and authenticity are ensured, to ensure the integrity and authenticity of the files that are used when the system is updated and at startup of the system.

Abstract: An information processing apparatus includes a RAM; a non-volatile memory storing setting information in which a compression method is set for each of a plurality of RAM disks, the setting information including a plurality of compression methods; and circuitry. The circuitry is configured to create each of the plurality of RAM disks with the compression method mounted, in the RAM, according to the setting information; request writing and reading of data from an application; write the data into a corresponding RAM disk of the plurality of RAM disks corresponding to the application, in response to a writing request of the data from the application; and compress the data in the compression method mounted on the corresponding RAM disk.

Abstract: An image forming device includes a memory, a memory controller, an error detector, a determiner, a print controller, a display, and a display controller. The memory controller acquires print information transmitted from an external device, and stores and controls the print information in the memory. The error detector detects a print error after start of printing of the print information. The determiner determines whether to execute sheet recovery processing to reprint a page in which the print error has occurred. The print controller controls a printing unit to execute the sheet recovery processing with the print information stored in the memory when a determination result to execute the sheet recovery processing is obtained. The display controller displays on the display a message indicating that the sheet recovery processing is not executed when a determination result not to execute the sheet recovery processing is obtained.
