Abstract: An information processing apparatus includes a memory that stores document data; a creating unit that creates access control information for controlling an access to the document data; a processor that applies an electronic signature to the document data, but does not apply the electronic signature to the access control information; and a controller that controls the access to the document data by using the access control information.

Abstract: An information processing apparatus includes a memory, a registration-interval extracting unit, and a determining unit. The memory stores multiple documents having a predetermined relationship. Each of the documents is stored in association with a registration date. The registration-interval extracting unit extracts the interval between the registration dates of the documents. The determining unit determines that the documents are to be published if a predetermined day count and the interval between the registration dates of the documents satisfy a predetermined condition.

Abstract: An information processing apparatus includes a receiving unit, an acquiring unit, an extracting unit, and a presenting unit. The receiving unit receives at least one document related to a treatment administered to a patient. The acquiring unit acquires a type of the document received by the receiving unit. The extracting unit extracts, from an association memory that stores a type of a first document and a type of a second document in association with each other, a type of a second document associated with the type of the document acquired by the acquiring unit, the second document being to be registered in a case where the first document is registered. The presenting unit presents the type of the second document extracted by the extracting unit for a document to be registered in conjunction with the document of the type acquired by the acquiring unit.

Abstract: A document processing apparatus includes a document acquiring unit that acquires image information representing an electronic document, a unit that determines whether the electronic document represented by the image information is an electronic document scanned from a document created by a specific hospital, and a storing unit that stores the image information in a memory if the electronic document represented by the image information is not an electronic document that is scanned from a document created by the specific hospital, and stores compressed image information, which is obtained by compressing the image information, in the memory in place of the image information if the electronic document represented by the image information is an electronic document scanned from a document created by the specific hospital.
