The present invention relates to an image reading system, an image reading apparatus, an information processing apparatus, a method for controlling them, and a storage medium.
Image reading systems are known that transmit an image read by an image reading apparatus, such as a multi-function printer, to an information processing apparatus, such as a PC or a mobile terminal, which can communicate with the image reading apparatus. In particular, a method in which, in the image reading system, a user performs operations related to image reading and transmission on the image reading apparatus side is called PushScan. Methods for designating a transmission destination of an image in the image reading system includes a method in which the user inputs an IP address of a transmission destination. However, with this method, the IP address of a transmission destination changes in an environment using DHCP, and accordingly the user needs to recheck the IP address of the transmission destination at the time of each transmission. Furthermore, there is also a possibility that the user fails to input the IP address due to a typing error or the like and transmits an image to an incorrect transmission destination.
In order to solve the aforementioned problem, Japanese Patent Laid-Open No. 2013-070311 proposes a technique for having a user select an information processing apparatus and setting the IP address of this information processing apparatus as a transmission destination, thereby setting the transmission destination without making the user aware of the IP address. Meanwhile, a technique called IP filtering for rejecting access from an IP address other than a specific IP address is known as a technique for preventing unauthorized access via a network.
However, the above conventional technique has the following problem. For example, in the image reading system in the above conventional technique, the information processing apparatus receives an image, and is therefore in a state of being able to be accessed from an external apparatus. Accordingly, the information processing apparatus may possibly be subjected to unauthorized access that is made intentionally or due to mistyping of the transmission destination, from an image reading apparatus other than the image reading apparatus that the user operates. Furthermore, in a case of using IP filtering in order to prevent unauthorized access, an operation of setting IP filtering needs to be additionally performed in a series of user operations for performing image reading.
The present invention enables realization of a mechanism that prevents unauthorized access to an information processing apparatus while suppressing a workload on a user in a series of image reading operations.

The components can mutually exchange data via the system bus 310.
Software Configuration of Image Reading System
Next, an exemplary software configuration of the image reading system 100 will be described with reference to
The reading apparatus selection unit 401 searches for image reading apparatuses on the network, displays them on the touch screen display 208, and determines that an image reading apparatus selected from among them by the user is a “reading target” apparatus. The search method may be automatic search using a unique protocol or a general protocol such as SNTP, or may be search conducted by manually inputting an IP address. The reading apparatus selection unit 401 then stores, in the storage 207, information related to the reading target apparatus. In the present embodiment, for example, a name, an IP address, and a Mac address of the apparatus are stored as the information (network information) related to the reading target apparatus.
The reception-waiting processing unit 402 permits access to the information processing apparatus 110 from an external apparatus, in accordance with a user instruction, and causes the application to transition to an image reception-waiting state. In the present embodiment, the reception-waiting processing unit 402 uses WebDAV as a protocol for receiving an image. WebDAV is a server/client communication protocol aimed for file management on a Web server. A transition to the image reception-waiting state in the present embodiment means that the reception-waiting processing unit 402 operates as a WebDAV server, and indicates reception of transmission from a WebDAV client.
The reception-waiting processing unit 402 also has an IP address filtering function, and can reject access from any IP address. Furthermore, after receiving a user instruction and before transitioning to the image reception-waiting state, the reception-waiting processing unit 402 checks whether the IP address has changed, based on the Mac address of the reading target, and if changed, the reception-waiting processing unit 402 updates the stored information using the changed IP address. Note that the method for checking an IP address using a Mac address may be a general means such as RARP, or may be a unique protocol. Furthermore, after receiving a user instruction and before transitioning to the image reception-waiting state, the reception-waiting processing unit 402 gives the information notification unit 403 an instruction to notify the image reading apparatus 130 of information (hereinafter referred to as notification information (connection information)) related to image reading and transmission.
The information notification unit 403 transmits, using the communication unit 202, the notification information to the reading target image reading apparatus 130, via the network 150. In the present embodiment, the information notification unit 403 transmits, as the notification information, the IP address of the information processing apparatus 110.
The image reading apparatus 130 has a reading processing unit 411 and a reading setting unit 412. The reading processing unit 411 reads an image using the scanner 304 in accordance with set content of the reading setting unit 412, and transmits the read image to a transmission destination, using the communication control unit 307. In the present embodiment, the reading processing unit 411 uses WebDAV as a communication protocol. The reading processing unit 411, which serves as a WebDAV client, transmits an image to the information processing apparatus 110, which serves as a WebDAV server.
The reading setting unit 412 displays, on the display unit 306, a setting screen related to various settings (image file format etc.) necessary for image reading and transmission destination settings. The user can give an instruction to execute image reading, after inputting setting items through the operation unit 305. The reading setting unit 412 stores, in the RAM 303 or the external storage device 309, the notification information transmitted from the information notification unit 403, and automatically inputs the information of which the reading setting unit 412 is notified to the setting items and displays the information, when displaying a setting UI on the display unit 306. In the present embodiment, since the information notification unit 403 transmits the IP address of the information processing apparatus 110 as the notification information, the reading setting unit 412 automatically inputs the IP address of the information processing apparatus 110 to a transmission destination setting item of the read image.
Selection Processing
Next, a procedure of processing performed when the information processing apparatus 110 selects an image reading apparatus in the present embodiment will be described with reference to
In step S501, the reading apparatus selection unit 401 searches for image reading apparatuses existing on the network. The search method may be automatic search or manual search, as mentioned in the description of the reading apparatus selection unit 401 in
In step S502, the reading apparatus selection unit 401 displays a search result screen 800 shown in
Upon the user (operator) tapping an icon of any of the found image reading apparatuses, in step S503, the reading apparatus selection unit 401 determines that the image reading apparatus indicated by the icon tapped by the user is selected as the reading target apparatus, and stores information related to the reading target in the storage 207. Then, the processing ends.
Note that
Reception Processing
Next, processing by which the information processing apparatus 110 receives an image in the present embodiment will be described with reference to
In step S601, the reception-waiting processing unit 402 determines whether or not selection of the reading target apparatus in step S503 has finished. If finished, the processing proceeds to step S603, and if not, the processing proceeds to step S602. In step S602, the reception-waiting processing unit 402 executes the flowchart in
In step S603, the reception-waiting processing unit 402 obtains the current IP address (latest network information) from the Mac address of the reading target apparatus. The method for obtaining an IP address from a Mac address may be a unique protocol or a general means such as RARP, as mentioned in the description of the reception-waiting processing unit 402 in
In step S604, the reception-waiting processing unit 402 gives an instruction to transmit the notification information to the information notification unit 403. The information notification unit 403 notifies the reading target apparatus of the information, and the processing proceeds to step S605. In the present embodiment, the reading target apparatus is notified of “transmission destination” information as the notification information. The “transmission destination” information is the IP address, e.g., “111.222.333.444”, of the information processing apparatus 110 serving as an address to which the image data of the original read by the image reading apparatus is transmitted.
In step S605, the reception-waiting processing unit 402 transitions to the image reception-waiting state, and the processing proceeds to step S606. In the present embodiment, the reception-waiting processing unit 402 displays an image transmission destination notification screen shown in
In step S607, the reception-waiting processing unit 402 compares the IP address of the reading target apparatus in
In step S608, the reception-waiting processing unit 402 permits the access from the external apparatus and accepts image reception. Then, the processing proceeds to step S609. In step S609, the reception-waiting processing unit 402 waits until image reception ends, and upon the reception ending, the reception-waiting processing unit 402 cancels the image reception-waiting state. Then, the processing proceeds to step S610. In the present embodiment, the reception-waiting processing unit 402 stops the operation for serving as a WebDAV server. In step S610, the reception-waiting processing unit 402 displays the received image on the touch screen display 208 as shown in
On the other hand, in step S611, the reception-waiting processing unit 402 rejects the access from the external apparatus, and the processing proceeds to step S612. In step S612, the reception-waiting processing unit 402 cancels the image reception-waiting state, and the processing proceeds to step S613. In step S613, the reception-waiting processing unit 402 displays, on the touch screen display 208, an unauthorized access occurrence notification screen for notifying the user that unauthorized access has occurred, as shown in
Storing Processing
Next, processing of the image reading apparatus 130 for storing the notification information in the present embodiment will be described with reference to
In step S1301, the reading setting unit 412 determines whether or not the notification information is already stored in the RAM 303 or the external storage device 309. If already stored, the processing proceeds to step S1302, and if not, the processing proceeds to step S1303. That is to say, here, old information is deleted, and new information of which the image reading apparatus 130 is notified is stored as the transmission destination of read image data. In step S1302, the reading setting unit 412 deletes the stored information, and the processing proceeds to step S1303. In step S1303, the reading setting unit 412 stores, as a setting item related to image reading, the information of which the image reading apparatus 130 is notified, and the processing ends. Note that, in the present embodiment, the information of which the image reading apparatus 130 is notified is “transmission destination” information, which is the IP address, e.g., “111.222.333.444”, of the information processing apparatus 110. Accordingly, the reading setting unit 412 stores the “transmission destination” information of which the image reading apparatus 130 is notified, as the transmission destination to which the read image data is to be transmitted after image reading is carried out.
Input Processing
Next, processing for inputting the notification information as the setting item related to image reading by the image reading apparatus 130 in the present embodiment will be described with reference to
In step S1401, the reading processing unit 411 determines whether or not the notification information is stored in the RAM 303 or the external storage device 309. If stored, the processing proceeds to step S1402, and if not, the processing ends. In step S1402, the reading processing unit 411 reads out the stored notification information, and determines whether or not the stored notification information includes an item corresponding to the setting item related to image reading. If a corresponding item is included, the processing proceeds to step S1403, and if not, the processing ends. For example, in the present embodiment, a “transmission destination” item in the image transmission destination setting screen shown in
In step S1403, the reading processing unit 411 causes the stored corresponding item to be reflected, as a value of the setting item including the corresponding information, in the setting screen, and displays it. Then, the processing ends. For example, if it is determined in step S1402 that an item corresponding to the “transmission destination” is included, the stored IP address such as “111.222.333.444” is used as the “transmission destination” item. For this reason, if the user causes the setting screen in
Image Reading Processing
Next, image reading processing of the image reading apparatus 130 in the present embodiment will be described with reference to
In step S1601, the reading processing unit 411 reads an image using the scanner 304, in accordance with image reading settings. The reading processing will not be described since it is similar to general reading processing for PushScan and is irrelevant to the essence of the present invention. After finishing the image reading, the processing proceeds to step S1602.
In step S1602, the reading processing unit 411 determines whether or not image reading has normally finished. If normally finished, the processing proceeds to step S1603, and if image reading ends due to an error, this processing ends. In step S1603, the reading processing unit 411 transmits the normally read image in accordance with the transmission settings. The details of the transmission processing will not be described since it is similar to general transmission processing for PushScan and is irrelevant to the essence of the present invention. After finishing transmission, the processing proceeds to step S1604.
In step S1604, the reading processing unit 411 determines whether or not image transmission has normally finished. If normally finished, the processing proceeds to step S1605, and if image transmission ends due to an error, this processing ends. In step S1605, if the notification information such as information of the “transmission destination” is stored, the reading processing unit 411 deletes this information, and this processing ends.
As described above, in the present image reading system, the information processing apparatus notifies any of the image reading apparatuses on the network of the connection information, and permits transmission of image data only in a case where the image reading apparatus notified of the connection information accesses the information processing apparatus. The image reading apparatus transmits image data that is read from an original, to the transmission destination conforming to the connection information of which the image reading apparatus is notified by the information processing apparatus. In this manner, the information processing apparatus according to the present embodiment selects an image reading apparatus from which the information processing apparatus receives image data, notifies the selected image reading apparatus of the information of the information processing apparatus, receives image data only from the image reading apparatus notified of the information, and rejects access from other apparatuses. Note that the image reading apparatus stores the information of which the image reading apparatus is notified by the information processing apparatus, and when configuring image reading settings, the image reading apparatus causes the content of the stored information to be reflected in the setting screen and displays it, and it is thereby possible to suppress a workload on the user. Accordingly, according to the present embodiment, it is possible to prevent unauthorized access to the information processing apparatus, while suppressing a workload on the user during a series of image reading operations.
Note that the present invention is not limited to the above embodiment, and may be modified in various manners. For example, a plurality of items, such as “IP address, protocol, and image file format”, may be transmitted, in place of the notification information, as the connection information. In this case, all items that are the corresponding items according to the determination in step S1402 are used as the items corresponding to the setting items in step S1403.
Embodiment(s) of the present invention can also be realized by a computer of a system or apparatus that reads out and executes computer executable instructions (e.g., one or more programs) recorded on a storage medium (which may also be referred to more fully as a ‘non-transitory computer-readable storage medium’) to perform the functions of one or more of the above-described embodiment(s) and/or that includes one or more circuits (e.g., application specific integrated circuit (ASIC)) for performing the functions of one or more of the above-described embodiment(s), and by a method performed by the computer of the system or apparatus by, for example, reading out and executing the computer executable instructions from the storage medium to perform the functions of one or more of the above-described embodiment(s) and/or controlling the one or more circuits to perform the functions of one or more of the above-described embodiment(s). The computer may comprise one or more processors (e.g., central processing unit (CPU), micro processing unit (MPU)) and may include a network of separate computers or separate processors to read out and execute the computer executable instructions. The computer executable instructions may be provided to the computer, for example, from a network or the storage medium. The storage medium may include, for example, one or more of a hard disk, a random-access memory (RAM), a read only memory (ROM), a storage of distributed computing systems, an optical disk (such as a compact disc (CD), digital versatile disc (DVD), or Blu-ray Disc (BD)™), a flash memory device, a memory card, and the like.
