  • Patent number: 9152631
    Abstract: A document management system determines that a plurality of versions to be managed is a version to be stored in a file server or in a document management apparatus, the version that is determined to be stored in the file server apparatus and the property information are registered in the file server apparatus, and the version that is determined to be stored in the document management server apparatus and the property information are registered in the document management server apparatus. Information about registration destination in the version registered in the file server is stored in the document management server apparatus. Such a configuration reduces the amount of use of a storage disk in the document management server apparatus to suppress the operation cost. Even if a management system is different, a document management system capable of managing data is provided.

  • Patent number: 8531694
    Abstract: The image forming apparatus holds related restriction information associated with function restriction information for restricting the use of a function provided within the network. With the related restriction information, when the image forming apparatus receives a job that executes a reading function and a transmission function, it displays, for a transmission source user, a settings screen for setting job operation settings in which restrictions held in the function restriction information and the related restriction information have been reflected. Furthermore, the image forming apparatus generates and transmits a send file in which the restrictions imposed on the transmission destination user have been reflected by using the job operation settings set via the settings screen, the function restriction information and the related restriction information.

  • Patent number: 8503004
    Abstract: A system accurately performs function restriction on a user-by-user basis, even in the case of an image processing function that is realizable with use of a plurality of apparatuses. To accomplish this, the image processing system includes a user restriction information management apparatus that has function restriction information and an image processing apparatus that has related restriction information. The image processing apparatus performs a user-designated function based on restriction content of the function restriction information and the related restriction information. There are cases where a restriction function, which is a function that is restricted by the function restriction information, can be realized by combining a plurality of other functions that are different from the restriction function, and related restriction information refers to information for restricting the usage of such other functions.

  • Patent number: 7912857
    Abstract: A start date of check-out processing of setting a shared document accessible by a plurality of users via a network into an exclusive state is reserved as a check-out start date based on an instruction of a user. In the exclusive state, the shared document can be updated by the user but cannot be updated by other users. When current date has reached the check-out start date, the shared document is set into the exclusive state for the user. The shared document can be released from the exclusive state in response to an instruction of the user checking-out the shared document. An expected check-in date to release the shared document from the exclusive state after the check-out start date can be reserved. This invention enables reservation for a document operation and prevents any decrease in the operation efficiency of users.

  • Patent number: 7849099
    Abstract: A check-out document cannot be updated by another operator unless an operator who checked out that document cancels the check-out status or checks in the document. To remove this inconvenience, document data is set in an exclusive state with respect to another user, and a password required to cancel the exclusive state is generated. The exclusive state of the document data is canceled based on an instruction of a user who instructed the exclusive state or an instruction of the other user with the password, thus updating the document data.
