Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention relates to an input processing system, an information storage device, an information processing device, and an input method. 
         [0003]    2. Description of the Related Art 
         [0004]    There has been software that is equipped with a function of storing information entered once and making the information be automatically entered at the subsequent entering in entering login information for logging into a service on a website or in entering input information into a form field (refer to Japanese Patent Application Laid-Open Publication No. 2004-015077). Such a type of software integrally manages and stores information to be input in association with information on input destinations. The software, however, is disadvantageous in that an access to the managed information can reveal the place where the information to be input will be used, since the information on input destinations and the information to be input in association with the information on input destinations are stored together in a device having the software installed. 
         [0005]    In order to address this problem, Japanese Patent Application Laid-Open Publication No. 2004-015077 describes a technique of storing input information such as a password into an external device that performs short-distance communications and acquiring the input information from the external device at each usage. 
         [0006]    This technique, however, is exposed to the risk of the information including a password being specified if one of a mobile communication terminal and a personal information transmitter is analyzed, since both the mobile communication terminal and the personal information transmitter store the password. 
       BRIEF SUMMARY OF THE INVENTION 
       [0007]    The present invention has been made in view of the above circumstances, and an object of the present invention is thus to provide an input processing system, an information storage device, an information processing device, and an input method which achieve higher levels of security by preventing a person from acquiring information necessary for input solely with a device associated with information input. 
         [0008]    According to an embodiment of the present invention, there is provided an input processing system including: an information storage device; and an information processing device, in which the information storage device includes: an input information storage unit configured to store information for performing input processing and identification information so that both of the information corresponds to each other; an identification information receiving unit configured to receive the identification information from the information processing device; and an information transmitting unit configured to transmit, to the information processing device, the information for performing input processing stored to correspond to the identification information received by the identification information receiving unit; the information processing device includes: an identification information storage unit configured to store the identification information; an identification information transmitting unit configured to transmit the identification information to the information storage device; and an information receiving unit configured to receive the information for performing input processing transmitted by the information transmitting unit. 
         [0009]    Further, according to an embodiment of the present invention, there is provided an information storage device including: an input information storage unit configured to store information for performing input processing and identification information so that both of the information corresponds to each other; an identification information receiving unit configured to receive the identification information from an external device; and an information transmitting unit configured to transmit, to the external device, the information for performing input processing stored to correspond to the identification information received by the identification information receiving unit. 
         [0010]    Furthermore, according to an embodiment of the present invention, there is provided an information processing device including: an identification information storage unit configured to store identification information used for identifying information for performing input processing stored in an external device, an identification information transmitting unit configured to transmit the identification information to the external unit; and an information receiving unit configured to receive the information for performing input processing transmitted from the external device. 
         [0011]    Moreover, according to an embodiment of the present invention, there is provided an input method that is executed by an information storage device having an input information storage unit and by an information processing device having an identification information storage unit, the input information storage unit being configured to store information for performing input processing and identification information so that both of the information corresponds to each other, and the identification information storage unit being configured to store the identification information, in which the input method includes the steps of: transmitting the identification information to the information storage device by the information processing device; receiving the identification information transmitted from the information processing device by the information storage device; and outputting the information for performing input processing corresponding to the received identification information to the information processing device.

     DETAILED DESCRIPTION OF THE INVENTION 
       [0018]    An embodiment of the present invention will be hereinafter described with reference to the drawings. 
         [0019]      FIG. 1  is a system configuration diagram illustrating a system configuration of an input system. 
         [0020]    An input system S includes an information processing device  1  and a wrist terminal  2  as shown in  FIG. 1 . 
         [0021]    The information processing device  1  is configured to enable viewing of a website or editing of a file, for example. The wrist terminal  2  is configured to pair with the information processing device  1  in a short-distance wireless communication standard such as NFC (Near Field Communication) or Bluetooth and be capable of data exchange with the information processing device  1 . 
         [0022]    The input system thus configured has a function of allowing registered information to be automatically input when viewing of a website or editing of a file, for example, is performed in the information processing device  1 . The automatically input information (hereinafter referred to as input information) is stored in an external device such as the body of the information processing device  1  or the wrist terminal  2 . If input information is stored in an external device such as the wrist terminal  2 , the information required for viewing a website or editing a file, for example, is not stored with the information on a target website or a target file but is stored in the form of actual raw data to be input. Hence, if the input information has been stolen from the wrist terminal  2 , the input information alone cannot determine the application of the information. Therefore, the security of the input system S can be increased when information including ID and a password necessary for logging into a specific website is stored. 
         [0023]      FIG. 2  is a block diagram illustrating a configuration of hardware of the information processing device  1  according to an embodiment of the present invention. The information processing device  1  is a mobile terminal such as a smartphone. 
         [0024]    The information processing device  1  includes a central processing unit (CPU)  11 , a read only memory (ROM)  12 , a random access memory (RAM)  13 , a bus  14 , an input/output interface  15 , an image taking unit  16 , an input unit  17 , an output unit  18 , a storage unit  19 , a communication unit  20 , and a drive  21 . 
         [0025]    The CPU  11  executes different types of processing in accordance with programs stored in the ROM  12  or programs loaded from the storage unit  19  into the RAM  13 . 
         [0026]    The RAM  13  adequately stores data, for example, that is necessary when the CPU  11  executes different types of processing. 
         [0027]    The CPU  11 , ROM  12 , and RAM  13  are connected to one another via the bus  14 . To the bus  14 , the input/output interface  15  is connected. To the input/output interface  15 , the image taking unit  16 , the input unit  17 , the output unit  18 , the storage unit  19 , the communication unit  20 , and the drive  21  are connected. 
         [0028]    The image taking unit  16  includes an optical lens unit and an image sensor not shown in the drawings. 
         [0029]    The optical lens unit is formed of a condenser lens collecting lights for taking an image of an object, such as a focus lens or a zoom lens. A focus lens is a lens that forms an image of an object on a light receiving surface of the image sensor, and a zoom lens is a lens that freely changes a focus distance within a limited range. The optical lens unit is additionally provided as needed with a peripheral circuit that adjusts setting parameters including a focus point, exposure, and white balance. 
         [0030]    The image sensor is formed of a photoelectric conversion element and an analog front end (AFE), for example. The photoelectric conversion element is, for example, a photoelectric conversion element of a complementary metal oxide semiconductor (CMOS) type. The photoelectric conversion element receives an image of an object emitted from the optical lens unit, and then photo-electrically converts (captures) the image and stores an image signal for a predetermined period of time. Further, the photoelectric conversion element sequentially supplies stored image signals to the AFE as analog signals. 
         [0031]    The AFE executes different types of signal processing including analog/digital (A/D) conversion processing, on the analog image signals. Through the signal processing, digital signals are generated and are output as output signals of the image taking unit  16 . The output signals of the image taking unit  16  will be hereinafter referred to as taken image data. The taken image data is adequately supplied to the CPU  11  and an image processing unit not shown in the drawings. 
         [0032]    The input unit  17  is formed of different types of buttons, and inputs various types of information in accordance with instruction operations of a user. The output unit  18  is formed of a display or a speaker, for example, and outputs images or sounds. The storage unit  19  is formed of a hard disk or a dynamic random access memory (DRAM), for example, and stores data of images. The communication unit  20  controls communications with other devices (not shown in the drawings) via a network including the Internet. 
         [0033]    The drive  21  is appropriately equipped with a removable media  31 , which may be any one of a magnetic disk, an optical disk, a magneto-optical disk and a semiconductor memory, and so forth. The drive  21  reads a program from the removable media  31  and the program is installed into the storage unit  19  if necessary. The removable media  31  can store various data including the data of images stored in the storage unit  19  as the storage unit  19  can. 
         [0034]    The wrist terminal  2  is formed as a watch device, for example. The wrist terminal  2  has the same configuration as the information processing device  1 , except that the wrist terminal  2  does not have the image taking unit  16  and the drive  21  including the removable media  31 , and the descriptions of the wrist terminal  2  will be thus omitted. It is to be noted that when the respective hardware configurations of the information processing device  1  and the wrist terminal  2  are to be separately mentioned, “−1” will be hereinafter attached to the reference numbers that denote the units of the information processing device  1  and “−2” will be hereinafter attached to the reference numbers that denote the units of the wrist terminal  2 . 
         [0035]      FIG. 3  is a functional block diagram illustrating a functional configuration for executing input processing of the functional configurations of the information processing device  1  and the wrist terminal  2  in  FIG. 1 . The input processing indicates processing of acquiring information necessary for viewing of a website, for example, from the wrist terminal  2  and making the information be automatically input when the information processing device  1  has accessed the website. In the meanwhile, exchange of information between the information processing device  1  and the wrist terminal  2  will be hereinafter conducted in a manner such that encoded information is output after device authentication and then the encoded information received is decoded. 
         [0036]    The input processing by the information processing device  1  is performed via an input detecting unit  51 , an information generation unit  52 , a memory control unit  53 , a communication control unit  54 , an output control unit  55 , an input object determination unit  56 , and an input processing unit  57  in a CPU  11 - 1 , as shown in  FIG. 3 . 
         [0037]    Moreover, in one region of a storage unit  19 - 1 , an input processing information storage unit  71  is set. In the input processing information storage unit  71  is stored information on an input destination, information necessary for input processing including the storage destination and the inquiry number of information to be input (hereinafter referred to as input object information), and information necessary for acquiring the input object information. 
         [0038]    The information used in the input system S will be described. In the input system S, information associated with input is managed by a management application.  FIGS. 4A and 4B  are drawings for describing information used in the input system S. 
         [0039]    The information used in the input system is separated into information stored in the information processing device  1  and information stored in the wrist terminal  2  described later. 
         [0040]    The information stored in the information processing device  1  indicates the “input destination numbers”, “input destinations”, “storage destinations”, and “inquiry numbers” as indicated in  FIG. 4A . The “input destination numbers” are numbers automatically allotted when information is stored. The “input destinations” are the information on input destinations, and is specifically a URL in the case of a website and is a place of use in the case of an application. The “storage destinations” are places where the input object information is stored. The place is the wrist terminal  2  (pairing  1 ) in the embodiment, although the input object information may be stored in other places such as the storage unit  19  (main body) of the information processing device  1  and the removable media  31  (memory card) equipped via the drive  21  of the information processing device  1 . The “inquiry numbers” are numbers serving as identification information when an inquiry is made about the acquisition of the input object information in the “storage destinations”. In the embodiment, there are different inquiry numbers stored for different storage destinations, respectively. In the input system S, the information processing device  1  manages the input object information according to the “inquiry numbers” and therefore the input object information cannot be made available by the information processing device  1  alone. 
         [0041]    On the other hand, the information stored in the wrist terminal  2  includes the “inquiry numbers” and “input object information  1  to n” as indicated in  FIG. 4B . The “inquiry numbers” are numbers used when an inquiry is made about input object information by an external device. The “inquiry numbers” are automatically created when input object information is registered from an external device. The “input object information” is secure information to be input when input is performed, and is managed by a set of input destinations such as a website and a file. In the embodiment, the input object information includes not only ID and a password but also a name, an address, etc. for inputting individual information. Storing the “inquiry numbers” and the “input object information” alone in the wrist terminal  2  can prevent a person from knowing what the “input object information” is directly used for with the wrist terminal  2  only. 
         [0042]    In  FIG. 3  again, the input detecting unit  51  detects input of information. Specifically, the input detecting unit  51  detects input of information such as ID and a password or detects information that determines whether or not input information is to be the input object information, in viewing of a website. 
         [0043]    The information generation unit  52  generates information related to input necessary for input (hereinafter referred to as input-related information). The information related to input necessary for input is the inquiry information and the input information including the input object information, for example. Specifically, the information generation unit  52  generates information with the items of “inquiry about input object information”, “input destinations”, and “storage destinations of input object information”, for storage in the information processing device  1 . Further, the information generation unit  52  generates, for each input set, input object information for an input destination for storage in the wrist terminal  2 . 
         [0044]    The memory control unit  53  controls the storage unit  19  so that the storage unit  19  stores information. More specifically, the memory control unit  53  controls the storage unit  19  so that the information with the items of “input destination of input object information” and “storage destination of input object information” can be stored in the input processing information storage unit  71  for storage in the information processing device  1 . Consequently, the memory control unit  53  allows the information indicated in  FIG. 4A  to be stored into an inquiry information storage unit  111 . 
         [0045]    The communication control unit  54  controls the communication unit  20  so that information is input/output to other devices. More specifically, the communication control unit  54  control the communication unit  20  so that data is output to the wrist terminal  2  for storage in the wrist terminal  2 , the data having information to be input separated in the items of “information  1 ” to “information n”. Further, the communication control unit  54  acquires an inquiry number from the wrist terminal  2 . The communication control unit  54  also sends an inquiry to the wrist terminal  2  about input information and acquires input information according to the inquiry. 
         [0046]    The output control unit  55  controls the output unit  18  so that a website or a file, for example, is output and displayed so as to be viewed. 
         [0047]    An input object determination unit  56  determines whether or not a website being viewed, for example is an input object. More specifically, the input object determination unit  56  makes a determination by checking against the input destinations stored in the input processing information storage unit  71 . 
         [0048]    The input processing unit  57  executes input processing. More specifically, the input processing unit  57  inputs input information acquired from the wrist terminal  2 , into an input object (a website or a file, for example) as input processing. 
         [0049]    The input processing in the wrist terminal  2  is performed via a communication control unit  91  and a memory control unit  92  in a CPU  11 - 2 , as shown in  FIG. 3 . 
         [0050]    Moreover, in one region of a storage unit  19 - 2 , an inquiry information storage unit  111  is set. In the inquiry information storage unit  111 , input object information is stored which corresponds to the inquiry number as shown in  FIG. 4B . 
         [0000]    The communication control unit  91  controls a communication unit  20 - 2  so that information is output from other devices. More specifically, the communication control unit  91  determines whether or not registration of input information has been requested. Further, the communication control unit  91  controls the communication unit  20  so that an inquiry number is output to the information processing device  1 . In addition, the communication control unit  91  determines whether there is an inquiry about input information. Moreover, the communication control unit  91  controls the communication unit  20  so that input information for an inquiry number is output to the information processing device  1 . 
         [0051]    The memory control unit  92  makes input object information stored. More specifically, the memory control unit  92  controls the inquiry information storage unit  111  so that input object information is stored. In the control, the memory control unit  92  issues an inquiry number according to an input destination. Consequently, the memory control unit  92  allows the information indicated in  FIG. 4B  to be stored in the inquiry information storage unit  111 . 
         [0052]      FIG. 5  is a flow chart for describing a flow of input processing executed by the information processing device  1  in  FIG. 2  having the functional configuration in  FIG. 3 . In the embodiment, an example will be described in which once ID and a password are input while a website is being viewed, the ID and the password will be used as input information. The input processing is started by the operation of input processing performed on the input unit  17  by a user. 
         [0053]    In Step S 11 , the input detecting unit  51  detects input of information such as ID and a password while a website is being viewed. 
         [0054]    In Step S 12 , the input detecting unit  51  determines whether or not the information having been input will be used as input object information. If the information having been input will be used as input object information, the input detecting unit  51  detects an operation for that determination. If the information having been input will not be used as input object information, Step S 12  makes a judgment of NO and the input processing ends. If the information having been input will be used as input object information, Step S 12  makes a judgment of YES and the procedure moves on to Step S 13 . 
         [0055]    In Step S 13 , the information generation unit  52  generates input-related information. Specifically, the information generation unit  52  generates information with the items of “inquiry of input object information”, “input destinations”, and “storage destinations of input object information”, for storage in the information processing device  1 . Further, the information generation unit  52  generates, for each input set, input object information for an input destination for storage in the wrist terminal  2 . 
         [0056]    In Step S 14 , the memory control unit  53  and the communication control unit  54  register input-related information. Specifically, the memory control unit  53  allows information with the items of “input destinations” and “storage destinations” as shown in  FIG. 4A  of information to be input, to be stored into the input processing information storage unit  71  for storage in the information processing device  1 . Further, the communication control unit  54  outputs, for each input set, input object information for an input destination for storage in the wrist terminal  2 . 
         [0057]    In Step S 15 , the communication control unit  54  acquires an inquiry number. In other words, the communication control unit  54  acquires from the wrist terminal  2  an inquiry number for the output input object information. 
         [0058]    In Step S 16 , the output control unit  55  controls an output unit  18 - 1  so that a website is output for viewing. 
         [0059]    In Step S 17 , the input object determination unit  56  determines whether or not a website being viewed is a website as an object of input. More specifically, the input object determination unit  56  makes a determination by checking against a list of input destinations stored in the input processing information storage unit  71 . If the website being viewed is not an object of input, Step S 17  makes a judgment of NO and the input processing ends. If the website being viewed is an object of input, Step S 17  makes a judgment of YES and the procedure moves on to Step S 18 . 
         [0060]    In Step S 18 , the communication control unit  54  makes an inquiry about the input object information. More specifically, the communication control unit  54  sends an inquiry to the wrist terminal  2  about the input object information by the inquiry number for the input destination stored in the input processing information storage unit  71 . As a result of the inquiry, the communication control unit  54  acquires the input object information from the wrist terminal  2 . It is to be noted that the input object information may be output only when the wrist terminal  2  has determined that the information processing device  1  is paired. 
         [0061]    In Step S 19 , the input processing unit  57  executes input processing. More specifically, the input processing unit  57  inputs the input object information acquired from the wrist terminal  2  into an input destination (website, for example) as input processing. A user can log-in with the input information (ID and a password). 
         [0062]      FIG. 6  is a flow chart for describing a flow of input processing executed by the wrist terminal  2  in  FIG. 2  having the functional configuration in  FIG. 3 . 
         [0063]    In Step S 41 , the communication control unit  91  determines whether or not registration of input object information has been requested. If there is no request for the registration, Step S 41  makes a judgment of NO and the input processing ends. If there is a request for the registration, Step S 41  makes a judgment of YES and the procedure moves on to Step S 42 . 
         [0064]    In Step S 42 , the memory control unit  92  makes the input information stored. More specifically, the memory control unit  92  controls the inquiry information storage unit  111  so that the input object information is stored. In the control, the memory control unit  92  issues an inquiry number according to an input destination. Consequently, the memory control unit  92  allows the information indicated in  FIG. 4B  to be stored in the inquiry information storage unit  111 . 
         [0065]    In Step S 43 , the communication control unit  91  outputs the inquiry numbers to the information processing device  1 . More specifically, the communication control unit  91  controls the communication unit  20  so that the inquiry numbers are output to the information processing device  1 . 
         [0066]    In Step S 44 , the communication control unit  91  determines whether or not there is an inquiry about the input object information. If there is no inquiry about the input object information, Step S 44  makes a judgment of NO and the input processing ends. If there is an inquiry about the input object information, Step S 44  makes a judgment of YES and the procedure moves on to Step S 45 . 
         [0067]    In Step S 45 , the communication control unit  91  outputs the input object information corresponding to the inquiry numbers. In other words, the communication control unit  91  controls the communication unit  20  so that the input object information corresponding to the inquiry numbers are output to the information processing device  1 . 
         [0068]    With the input system S thus configured, the security is not easily compromised even if the information processing device  1  or the wrist terminal  2  is accidentally left, unless the devices are hold. In this way, it becomes possible to prevent, without fail, highly confidential information such as a password and personal information from being automatically input into a form by an input information management application or the cloud service, for example. Further, since the wrist terminal  2  is worn on an arm of a user, the user can automatically input information including ID and a password only by operating the information processing device  1  without performing the input operation. Further, since the information processing device  1  and the wrist terminal  2  communicate with each other by short-distance communication, encryption and digital sign are enabled with hardware security codes including a device serial number and a media access control address (MAC) number. This achieves reduction in the risk of hacking, for example, more than when a device connected to the Internet or a mobile net, for example, is used. In addition, dealing with only information that relates to required input information can make the risk of hacking, etc. lower than when all the information is integrally managed. 
         [0069]    The information processing device  1  formed described above includes the communication control unit  54  and the input processing unit  57 . The communication control unit  54  controls the communication unit  20  so that input object information to be information for performing input is registered into the wrist terminal  2  as an external device. The communication control unit  54  further controls the communication unit  20  so that an inquiry number serving as management information for the registered input object information is acquired from the wrist terminal  2 . The communication control unit  54  further controls the communication unit  20  based on the acquired inquiry information so that input object information is acquired. The input processing unit  57  performs input into an input destination based on the input object information of which acquisition is controlled by the communication control unit  54 . In this way, the input object information is managed by an external device with no direct involvement of the information processing device  1 , so that the security is improved. 
         [0070]    The wrist terminal  2  is a paired device. Hence, the information processing device  1  performs communication with devices with security of higher levels. 
         [0071]    Further, the input system S employs the wrist terminal  2  performing short-distance communications. In the input system S, since the wrist terminal  2  is worn on an arm of a user, the user can automatically input information including ID and a password only by operating the information processing device  1  without performing the input operation. In addition, the wrist terminal  2  does not function when it gets stolen to a place far away from the information processing device  1   
         [0072]    The communication control unit  54  registers secure information including ID and a password necessary for logging into a website, for example, into the wrist terminal  2  as input object information. In this way, the input object information is managed by an external device with no direct involvement of the information processing device  1 , so that the security is improved. 
         [0073]    In the meanwhile, the present invention is not limited to the above embodiment and includes variations and modifications that occur within the range in which the objects of the present invention can be accomplished. 
         [0074]    While information having been input is set to be automatically input in the embodiment, the information having been input may be selectively input by a user in a manner such the user sees the displayed candidates of the information. 
         [0075]    Further, while as the information processing device  1  and the wrist terminal  2  in the input system S according to the present invention, a smartphone and a watch device are used, respectively, in the embodiment, they are not the only examples of the information processing device  1  and the wrist terminal  2 . For example, the present invention is applicable to general electronic devices with an input processing function. More specifically, the present invention is applicable to notebook-sized personal computers, printers, television receivers, video cameras, mobile navigation devices, mobile phones, smartphones, portable game machines, and so forth. 
         [0076]    The series of processing described above can be executed by either hardware or software. In other words, the functional configuration in  FIG. 3  is only exemplary. It is sufficient if the information processing device  1  is equipped with functions that can practically execute the series of processing and any other functional block than that in  FIG. 3  may be used for realizing the functions. Further, a single function block may be formed of hardware only, software only, or a combination of hardware and software. 
         [0077]    If the series of processing is to be executed by software, the programs of the software are installed from a network or a recording medium into a computer, for example. The computer may be a computer build in dedicated hardware, or be a computer such as a general personal computer that is capable of executing different functions with different programs installed therein. 
         [0078]    The recording medium having the programs includes not only the removable media  31  in  FIG. 2  distributed separately from the device body to a user for providing the user with programs but also a recording medium built in the device body in advance and provided to the user. The examples of the removable media  31  include a magnetic disk (floppy disk, for example), an optical disk, and a magneto-optical disk. The examples of the optical disk include a compact disk-read only memory (CD-ROM), a digital versatile disk (DVD), and a Blu-ray Disc (registered trademark). The magneto-optical disk is an MD (Mini-Disk), for example. Further, the recording medium built in the device body in advance and provided to the user is the ROM  12  in  FIG. 2  storing programs or hardware contained in the storage unit  19  in  FIG. 2 , for example. 
         [0079]    In the specification, the steps of describing the programs stored in the recording medium include not only processing performed in accordance with the order of the steps but also processing performed in parallel with one another or individually performed. Further, in the specification, the terms for the system denote an overall device including a plurality of devices or units. 
         [0080]    While several embodiments of the present invention have been described, the embodiments are only exemplary and do not limit the technical range of the present invention. It should be understood that the present invention may be implemented in other different embodiments and various kinds of alterations including omissions and replacements may occur as long as they are within the gist of the present invention. The embodiments and modified examples are within the scope and gist of the invention described in the specification, etc., and within the scope of the invention described in the appended claims or the equivalents thereof.
