According to one embodiment, there is provided a method for auditing shredding data including first count information in a system for auditing shredding data. The audit method includes causing a paper sheet processing apparatus to generate a first MAC based on the first count information using a first MAC generation key, causing the paper sheet processing apparatus to transmit the first count information and the first MAC to a first computing unit, causing the first computing unit to obtain second count information based on the first MAC using a second MAC generation key, causing the first computing unit to compare the first count information and the second count information, and determining an audit result.

An information processing device includes a reception unit that receives an instruction to delete a preregistered user, a storage unit that stores related information that relates to a process that the user executes on the information processing device itself, and a deletion unit that deletes the related information stored in the storage unit corresponding to a user targeted for deletion received by the reception unit.

A method and system for maintaining privacy in private postal mail, such as privileged or other legal postal mail or medical mail, at a correctional facility comprising a privacy verification system to verify a privacy status of a sender and generate privacy status identifiers to be used on the legal postal mail. The privacy status identifiers when scanned or observed at a mail processing facility that processes incoming mail sent to inmates who are incarcerated in a correctional facility provides an indication to the mail processing facility that the mail is private so that appropriate measures can be taken to maintain privacy status.

A memory controller includes a data discard controller, calculates a physical address of discard object data designated by a logical address by a host device, and registers the calculated physical address as discard object data information. With respect to a predetermined command from the host device, the data discard controller outputs current discard object data information to the host device. When no command is received from the host device, the data discard controller physically erases the discard object data on the basis of the discard object data information.

A method and system for eliminating contraband in legal postal mail at a correctional facility comprising of a facility-use legal mail scanning station and a network of inmate-accessible devices and or messaging systems such that correctional institution staff can inspect the legal mail for contraband without violating an inmate's right to privacy for such mail. The legal mail is scanned by the staff member or inmate under the supervision of a staff member and then shredded or placed into the inmate's personal property in secure storage. The scanned mail may then be made available to the intended inmate through the inmate-accessible devices or printed at the scanning station to ensure the elimination of contraband.

A method and system for maintaining privacy in private postal mail, such as privileged or other legal postal mail or medical mail, at a correctional facility comprising a privacy verification system to verify a privacy status of a sender and generate privacy status identifiers to be used on the legal postal mail. The privacy status identifiers when scanned or observed at a mail processing facility that processes incoming mail sent to inmates who are incarcerated in a correctional facility provides an indication to the mail processing facility that the mail is private so that appropriate measures can be taken to maintain privacy status.

A post-processing apparatus includes an acquisition section configured to acquire position information of a storage section arranged in a sheet; a destruction section configured to destroy the storage section; and a controller configured to operate the destruction section based on the position information of the storage section acquired by the acquisition section if a predetermined condition is met. The destruction section includes a standby section where the sheet stands by, a folding section configured to destroy the storage section by saddle-folding the sheet, and a sheet position adjustment mechanism configured to move the sheet placed in the standby section so that a position of the storage section becomes a position of the folding section.

An image forming apparatus has a scanning apparatus. The scanning apparatus has a control panel to enter operating instructions to the image forming apparatus to scan and store a document or scan, store and shred the document. The scanning apparatus has a feeding mechanism. A scanning mechanism is coupled to the feeding mechanism scanning and storing the document placed within the feeding mechanism. A shredding apparatus is coupled to the scanning apparatus. The shredding apparatus has a housing. A shredding feed mechanism is coupled to the scanning apparatus feeding the document from the scanning apparatus into the shredding apparatus when scan, store and shred is selected on the control panel. A cutting mechanism is in communication with the shredding feed mechanism shredding the document when scan, store and shred is selected on the control panel.

An image processing apparatus includes an image reading section for reading an image of a document to generate image data including image abnormality, and a hardware processor. The hardware processor performs the following processing: Transmitting the image data to an external apparatus; determining whether or not the image data includes confidential information; when it is determined that the image data includes confidential information, saving the image data in a predetermined storage section without transmitting the image data to the external apparatus; and when the image data is saved in the storage section, transmitting access information for accessing the image data saved in the storage section to the external apparatus.

An image capturing apparatus receives a request for image capturing commission from an information processing apparatus, saves a captured image file obtained by image capturing, transmits the captured image file, to the information processing apparatus and disable access to the saved captured image file.
