Abstract
A client unit 1 which a user uses to request for data, an agent unit 2 which keeps encrypted document data and attributes information, a document managing unit 3 which executes user authentication, access control and document image edition by means of decrypting of encrypted document data each have a processing function and an interface function which are independent of each other, and are connected via a communication network. This realizes a new data managing method which makes it easy to retrieve document data from a database through an on-line use or to search, output and otherwise document data in a single computer system, and therefore, a high level of security is achieved.
Claims17
A data managing method for management of data, including extraction of recorded data, in accordance with a request from a user, wherein
- said method uses data handling means which handles said recorded data and data managing means which is connected with said data handling means and manages the recording states of said recorded data,
- said data handling means passes said data managing means with recording location information which is indicative of the recording locations of said recorded data, and
- said data managing means saves the passed recording location information, retrieves the recording location of requested data from the saved recording location information in response to a request from a user, and extracts data through said data handling means based on the retrieved recording location.
A data managing system, comprising:
- a client unit which a user uses to request for data;
- an agent unit which saves encrypted document data and attributes information;
- a document managing unit which executes user authentication, access control and document image edition by means of decrypting of encrypted document data;
- wherein
- each said unit has a processing function and an interface function which are independent of each other, and are connected via a communication network.
A data managing system which comprises a data handling mechanism for handling recorded data, a terminal mechanism for requesting for outputting of data recorded in said data handling mechanism, a data managing mechanism being connected with said data handling mechanism and for managing the recording states of said recorded data, and manages said data recorded in said data handling mechanism, wherein
- said data handling mechanism comprises means for transmitting to said data managing mechanism recording location information indicative of the recording locations of said recorded data, and
- said data managing mechanism comprises:
- means for saving the received recording location information;
- means for retrieving the recording location of requested data from the saved recording location information in response to a request from said terminal mechanism;
- means for extracting data through said data handling mechanism based on the retrieved recording location;
- means for converting the extracted data into a predetermined format set in advance;
- and
- means for transmitting to said terminal mechanism said data converted into said predetermined format.
A data managing system which comprises a terminal mechanism for outputting data of an image format and a data managing mechanism for supporting management of data by said terminal mechanism, and manages data recorded in said terminal mechanism, wherein
- said terminal mechanism comprises means for transmitting to said data managing mechanism recorded data and format information indicative of an image format at outputting of said data;
- and
- said data managing mechanism comprises:
- means for converting received data into an image format expressed by the received format information;
- and
- means for transmitting said data converted into the image format to said terminal mechanism.
A data managing apparatus which manages the recording states of recorded data, comprising:
- means for receiving recording location information indicative of the recording locations of said recorded data;
- means for saving the received recording location information;
- means for retrieving the recording location of requested data from the saved recording location information when data output is requested;
- means for extracting data based on the searched recording location;
- and
- means for converting extracted data into a predetermined format set in advance.
A data handling apparatus which handles recorded data, comprising:
- means for transmitting recording location information indicative of the recording locations of said recorded data to a data managing apparatus which manages the recording states of said recorded data;
- and
- means for transmitting requested data when receiving from said data managing apparatus a data send request based on a recording location.
A computer program which causes a computer to manage the recording states of recorded data, comprising following procedures of:
- when receiving recording location information indicative of the recording locations of said recorded data, causing a computer to save the received recording location information;
- when being requested outputting of data, causing a computer to retrieve the recording location of requested data from the saved recording location information;
- causing a computer to extract data based on the retrieved recording location;
- and
- causing a computer to convert extracted data into a predetermined format set in advance.
A computer program which causes a computer to handle recorded data, comprising following procedures of:
- causing a computer to transmit recording location information indicative of the recording locations of said recorded data to a data managing apparatus which manages the recording states of said recorded data;
- and
- when receiving a data send request based on a recording location, causing a computer to transmit requested data from a data apparatus.
A computer readable recording medium which records a computer program for causing a computer to manage the recording states of:
- recorded data, comprising following procedures of
- when receiving recording location information indicative of the recording locations of said recorded data, causing a computer to save the received recording location information;
- when being requested outputting of data, causing a computer to retrieve the recording location of requested data from the saved recording location information;
- causing a computer to extract data based on the retrieved recording location;
- and
- causing a computer to convert extracted data into a predetermined format set in advance.
A computer readable recording medium which records a computer program for causing a computer to handle recorded data, comprising:
- program code means for causing a computer to transmit recording location information indicative of the recording locations of said recorded data to a data managing apparatus which manages the recording states of said recorded data;
- and
- program code means for, when a data send request based on a recording location is received, causing a computer to transmit requested data.
