FIG. 4 is a diagram illustrating an exemplary authentication card 100 serving as an exemplary medium for identification. In this example, an employee ID card on which a photograph of a user's face is printed is illustrated as the authentication card 100. On the authentication card 100, the company name (XX Inc.) and the user name (Taro YY) are described on the left side of the figure, and a photograph of the user's face is printed on the right side of the figure. When an employee ID card or the like is used as the authentication card 100, electronic information may be added to the authentication card 100 by using an integrated circuit (IC) chip embedded in the authentication card 100, or magnetic information may be added by using a magnetic tape provided for the authentication card 100.
FIG. 4 illustrates an entire area 100a including the entire surface of the authentication card 100 and a specified area 100b including a part of the area (a central portion in this example) of the authentication card 100. In the description below, a feature value extracted from data which is read from the entire area 100a of the authentication card 100 is called an entire feature value. A feature value extracted from data which is read from the specified area 100b of the authentication card 100 is called a partial feature value. The user feature value described above includes an entire feature value (hereinafter referred to as an entire user feature value A) and a partial feature value (hereinafter referred to as a partial user feature value B). The read feature value described above also includes an entire feature value (hereinafter referred to as an entire read feature value a) and a partial feature value (hereinafter referred to as a partial read feature value b).
FIG. 5 is a diagram for describing an exemplary configuration of the user data stored in the user-data storage unit 23 (See FIG. 2).
In the first exemplary embodiment, the user data is data in which a user identification (ID) as exemplary user identification information which is given to each of the users, the user feature value (the entire user feature value A and the partial user feature value B) as exemplary user feature value information which is obtained by reading the authentication card 100 carried by the user in advance, and the user image data C including the document image data which is obtained in such a manner that the user uses the scanner 30 to read the document 200 are associated with each other.
In the example illustrated in FIG. 5, the user ID “000001” is assigned to the owner (Taro YY in XX Inc.) of the authentication card 100 illustrated in FIG. 4. Thus, the entire user feature value A1 corresponding to the user ID “000001” is based on the reading result of the entire area 100a of the authentication card 100 illustrated in FIG. 4. The partial user feature value B1 corresponding to the user ID “000001” is based on the reading result of the specified area 100b of the authentication card 100 illustrated in FIG. 4. FIG. 5 illustrates user data for three users (user IDs “000001” to “000003”). Actually, the number of pieces of user data matches the number of users who use the service.
FIG. 6 is a diagram for describing an exemplary configuration of reservation data stored in the reservation storage unit 252 (see FIG. 2).
In the first exemplary embodiment, the reservation data is data in which a reservation number, an exclusive-use instruction, and a remaining time are associated with each other. The exclusive-use instruction has a data configuration in which the user ID of a user who has transmitted a request for exclusive use is associated with the user feature value (the entire user feature value A and the partial user feature value B) corresponding to the user ID. The remaining time is a time with which countdown is started at the time when the reservation is registered in the reservation storage unit 252. When the remaining time reaches 0:00, the reservation of the corresponding reservation number is deleted.
In the example illustrated in FIG. 6, two reservations for the user IDs “000001” and “000003” are set. The number of reservations which may be received is not limited to two, and may be one or more than two.
FIG. 7 is a sequence chart for describing an exemplary first operation in the scan service system 1 according to the first exemplary embodiment. FIG. 7 illustrates a case in which a user who has made a reservation by transmitting a request for exclusive use uses the scanner 30 before a timeout occurs in a timer using the remaining time.
In one of the clients constituting the client group 10, a user opens a web browser corresponding to the scan service, thereby starting use of the scan service. Then, the user transmits a request for exclusive use of the scanner 30 on the web browser, whereby the request for exclusive use is output from the client to the server 20. The request for exclusive use includes the user ID of the user who has transmitted the request.
In the server 20, the exclusive-use instruction generating unit 24 receives the request for exclusive use via the input/output unit 21. Then, the exclusive-use instruction generating unit 24 obtains the user ID included in the received request for exclusive use, and transmits the obtained user ID to the user-data management unit 22. The user-data management unit 22 refers to the user data stored in the user-data storage unit 23, and reads out the user feature value (the entire user feature value A and the partial user feature value B) corresponding to the user ID. The user-data management unit 22 transmits the user feature value corresponding to the user ID, back to the exclusive-use instruction generating unit 24. The exclusive-use instruction generating unit 24 generates an exclusive-use instruction in which the user ID included in the request for exclusive use is associated with the user feature value received from the user-data management unit 22, and outputs it to the exclusive-use setting unit 25.
In the exclusive-use setting unit 25, the exclusive-use state management unit 251 which receives the exclusive-use instruction registers the exclusive-use instruction as reservation data in the reservation storage unit 252, and starts countdown of the remaining time by using a timer.
The user who has transmitted the exclusive-use instruction via the client goes to the scanner 30, sets the authentication card 100 carried by the user himself/herself, on the image reading unit 33, and makes the image reading unit 33 read an image. The authentication image data obtained by reading the authentication card 100 is output via the reading controller 32 and the input/output unit 31 from the scanner 30 to the server 20.
In the server 20, the feature-value extracting unit 253 included in the exclusive-use setting unit 25 receives the authentication image data via the input/output unit 21. The feature-value extracting unit 253 extracts a feature value from the received authentication image data, and obtains a read feature value including an entire read feature value a based on the entire area 100a and a partial read feature value b based on the specified area 100b. The feature-value extracting unit 253 transmits the obtained read feature value to the checking unit 254.
The checking unit 254 transmits an inquiry to the exclusive-use state management unit 251. The exclusive-use state management unit 251 transmits reservation data stored in the reservation storage unit 252 back to the checking unit 254. The checking unit 254 checks the read feature value received from the feature-value extracting unit 253 against the reservation data (user feature values) received from the exclusive-use state management unit 251, and determines whether or not a user feature value matches the read feature value.
If a user feature value in the reservation data matches the read feature value, the checking unit 254 outputs a request to read a document which is exemplary instruction information, via the input/output unit 21 from the server 20 to the scanner 30.
In the scanner 30, the reading controller 32 receives the request to read a document through the input/output unit 31. The reading controller 32 which receives the request to read a document permits the user reading of the document 200. The user sets the document 200 on the image reading unit 33, and makes the image reading unit 33 read an image. The document image data thus obtained by reading the document 200 is output via the reading controller 32 and the input/output unit 31 from the scanner 30 to the server 20.
In the server 20, the user-data management unit 22 receives the document image data via the input/output unit 21. The user-data management unit 22 registers (stores) the received document image data as the user image data C in the user-data storage unit 23 in such a manner that the document image data is associated with the corresponding user ID, and the series of processes end.
In this example, the user-data storage unit 23 stores the user image data C, as it is, in such a manner that the user image data is associated with a user ID. This exemplary embodiment is not seen to be limiting. For example, in the case where a configuration is employed in which the user image data C is stored in a data server (not illustrated) provided outside the server 20, the user-data storage unit 23 may register the uniform resource locator (URL) of the data server in which the user image data C is stored in such a manner as to be associated with a user ID.
FIG. 8 is a sequence chart for describing an exemplary second operation in the scan service system 1 according to the first exemplary embodiment. FIG. 8 illustrates a case in which a user who has not made a reservation by transmitting a request for exclusive use, or whose reservation made by transmitting a request for exclusive use has been released due to a timeout uses the scanner 30. In the example illustrated in FIG. 8, the procedure until the server 20 performs checking is the same as that in the example illustrated in FIG. 7. Therefore, the detail of the procedure will not be described.
If no user feature values in the reservation data match the read feature value, the checking unit 254 outputs an error notification via the input/output unit 21 from the server 20 to the scanner 30.
In the scanner 30, the reading controller 32 receives the error notification via the input/output unit 31. The reading controller 32 which receives the error notification prohibits the user from using the image reading unit 33 to read the document 200, and the series of processes end.

FIG. 11 is a sequence chart for describing an exemplary first operation in the scan service system 1 according to the second exemplary embodiment. FIG. 11 illustrates a case in which a user who has made a reservation by transmitting a request for exclusive use uses the scanner 30 before a timeout occurs in a timer using the remaining time.
In one of the clients constituting the client group 10, a user opens a web browser corresponding to the scan service, thereby starting use of the scan service. Then, the user transmits a request for exclusive use of the scanner 30 on the web browser, whereby the request for exclusive use is output from the client to the server 20. The request for exclusive use includes the user ID of the user who has transmitted the request.
In the server 20, the exclusive-use instruction generating unit 24 receives the request for exclusive use via the input/output unit 21. Then, the exclusive-use instruction generating unit 24 obtains the user ID included in the received request for exclusive use, and transmits the obtained user ID to the user-data management unit 22. The user-data management unit 22 refers to the user data stored in the user-data storage unit 23, and reads out the user feature value (the entire user feature value A and the partial user feature value B) corresponding to the user ID. The user-data management unit 22 transmits the user feature value corresponding to the user ID, back to the exclusive-use instruction generating unit 24. The exclusive-use instruction generating unit 24 generates an exclusive-use instruction in which the user ID included in the request for exclusive use is associated with the user feature value received from the user-data management unit 22, and outputs it via the input/output unit 21 from the server 20 to the scanner 30.
In the scanner 30, the exclusive-use state management unit 341 included in the exclusive-use setting unit 34 receives the exclusive-use instruction via the input/output unit 31. The exclusive-use state management unit 341 registers the exclusive-use instruction as reservation data in the reservation storage unit 342, and starts countdown of the remaining time by using a timer.
The user who has transmitted the exclusive-use instruction via the client goes to the scanner 30, sets the authentication card 100 carried by the user himself/herself, on the image reading unit 33, and makes the image reading unit 33 read an image. The authentication image data obtained by reading the authentication card 100 is transmitted through the reading controller 32 and the input/output unit 31 to the exclusive-use setting unit 34. In the scanner 30, the feature-value extracting unit 343 included in the exclusive-use setting unit 34 receives the authentication image data. The feature-value extracting unit 343 extracts a feature value from the received authentication image data, and obtains a read feature value including an entire read feature value a based on the entire area 100a and a partial read feature value b based on the specified area 100b. The feature-value extracting unit 343 transmits the obtained read feature value to the checking unit 344.
The checking unit 344 transmits an inquiry to the exclusive-use state management unit 341. The exclusive-use state management unit 341 transmits reservation data stored in the reservation storage unit 342 back to the checking unit 344. The checking unit 344 checks the read feature value received from the feature-value extracting unit 343 against the reservation data (user feature values) received from the exclusive-use state management unit 341, and determines whether or not a user feature value matches the read feature value.
If a user feature value in the reservation data matches the read feature value, the checking unit 344 outputs a request to read a document, to the reading controller 32. The reading controller 32 which receives the request to read a document permits the user reading of the document 200. The user sets the document 200 on the image reading unit 33, and makes the image reading unit 33 read an image. The document image data thus obtained by reading the document 200 is output via the reading controller 32 and the input/output unit 31 from the scanner 30 to the server 20.
In the server 20, the user-data management unit 22 receives the document image data via the input/output unit 21. The user-data management unit 22 registers (stores) the received document image data as the user image data C in the user-data storage unit 23 in such a manner that the document image data is associated with the corresponding user ID, and the series of processes end.

In the exclusive-use setting apparatus 50, the feature-value extracting unit 503 receives the authentication image data via the input/output unit 500. The feature-value extracting unit 503 extracts a feature value from the received authentication image data, and obtains a read feature value including an entire read feature value a based on the entire area 100a and a partial read feature value b based on the specified area 100b. The feature-value extracting unit 503 transmits the obtained read feature value to the checking unit 504.
The checking unit 504 transmits an inquiry to the exclusive-use state management unit 501. The exclusive-use state management unit 501 transmits reservation data stored in the reservation storage unit 502 back to the checking unit 504. The checking unit 504 checks the read feature value received from the feature-value extracting unit 503 against the reservation data (user feature values) received from the exclusive-use state management unit 501, and determines whether or not a user feature value matches the read feature value.
If a user feature value in the reservation data matches the read feature value, the checking unit 504 outputs a request to read a document, via the input/output unit 500 from the exclusive-use setting apparatus 50 to the scanner 30.
In the scanner 30, the reading controller 32 receives the request to read a document via the input/output unit 31. The reading controller 32 which receives the request to read a document permits the user reading of the document 200. The user sets the document 200 on the image reading unit 33, and makes the image reading unit 33 read an image. The document image data thus obtained by reading the document 200 is output via the reading controller 32 and the input/output unit 31 from the scanner 30 to the server 20.
In the server 20, the user-data management unit 22 receives the document image data via the input/output unit 21. The user-data management unit 22 registers (stores) the received document image data as the user image data C in the user-data storage unit 23 in such a manner that the document image data is associated with the corresponding user ID, and the series of processes end.
FIG. 16 is a sequence chart for describing an exemplary second operation in the scan service system 1 according to the third exemplary embodiment. FIG. 16 illustrates a case in which a user who has not made a reservation by transmitting a request for exclusive use, or whose reservation made by transmitting a request for exclusive use has been released due to a timeout uses the scanner 30. In the example illustrated in FIG. 16, the procedure until the exclusive-use setting apparatus 50 performs checking is the same as that in the example illustrated in FIG. 15. Therefore, the detail of the procedure will not be described.
If no user feature values in the reservation data match the read feature value, the checking unit 504 outputs an error notification via the input/output unit 500 from the exclusive-use setting apparatus 50 to the scanner 30.
In the scanner 30, the reading controller 32 receives the error notification via the input/output unit 31. The reading controller 32 which receives the error notification prohibits the user from using the image reading unit 33 to read the document 200, and the series of processes end.
According to the first to third exemplary embodiments, the description is made by taking the case in which the scan service system 1 is implemented as a so-called server-client system, as an example. However, the scan service system 1 is not limited to this. The scan service system 1 may be implemented as a so-called cloud computing system.
The foregoing description of the exemplary embodiments of the present invention has been provided for the purposes of illustration and description. It is not intended to be exhaustive or to limit the invention to the precise forms disclosed. Obviously, many modifications and variations will be apparent to practitioners skilled in the art. The embodiments were chosen and described in order to best explain the principles of the invention and its practical applications, thereby enabling others skilled in the art to understand the invention for various embodiments and with the various modifications as are suited to the particular use contemplated. It is intended that the scope of the invention be defined by the following claims and their equivalents.
