[0045] <Overview>

[0046] Figure 1 is a diagram showing an example of a wireless communication system according to the present technology.

[0047] like Figure 1 As shown, the wireless communication system 1 is used when a user brings a device 11 including an IC chip close to a reader / writer 12 installed in, for example, a ticket gate of a station and enters the ticket gate.

[0048] The device 11 is a mobile terminal that a user can carry, such as a smartphone or a mobile phone. The device 11 may be configured by a wearable terminal such as a head mounted display or a watch. The device 11 performs near field wireless communication with the reader / writer 12 in a contactless manner via electromagnetic waves.

[0049] When the IC chip included in the device 11 is brought close to the reader / writer 12, the IC chip executes a command that has been transmitted from the reader / writer 12, and performs predetermined processing such as reading / writing data stored in a memory included therein.

[0050] The reader / writer 12 performs near-field wireless communication with the IC chip of the device 11 via electromagnetic waves to send a predetermined command to the IC chip, and allows the IC chip to execute the command and receive the processing result of the command sent from the IC chip. Among the commands sent by the reader / writer 12, for example, there is a command for writing a numerical value indicating the state of the user inside the ticket gate.

[0051] In the memory inside the IC chip, there are set a specific area and a protection area. A numerical value indicating the user's state inside the ticket gate is written in the specific area, and the protection area serves as a storage area for, for example, the balance of electronic money to be protected.

[0052] In the case where a numerical value indicating that the user is in a state inside the ticket gate is written into a specific area of ​​the IC chip in response to the transmitted command, the device 11 determines that the user has no intention to use the protected area inside the IC chip, and controls to set the protected area to a use-prohibited state. In the device 11, information indicating which numerical value to be written into the specific area indicates that the user has an intention to use the protected area (an intention to use the information stored in the protected area) is managed.

[0053] The usability status of the protected area inside the IC chip is switched in response to a command sent from the reader / writer 12, so that the user can prevent skimming while riding in a vehicle and any other skimming behavior without the user's own settings to allow / prohibit the use of electronic money functions and any other protected objects in similar situations.

[0054] <Configuration Example of Wireless Communication System>

[0055] Figure 2 is a block diagram showing a configuration example of a device and a reader / writer.

[0056] The device 11 includes a wireless communication section 31 , an IC chip 32 , a device host 33 , and a storage section 34 .

[0057] The wireless communication section 31 receives a command transmitted from the reader / writer 12, and outputs the received command to the IC chip 32. The wireless communication section 31 transmits a processing result of the command to the reader / writer 12.

[0058] The IC chip 32 includes a memory 40 and an information update unit 43. The memory is formed with a specific area 41 and a protection area 42. The information update unit 43 is realized by causing a controller (not shown) inside the IC chip 32 to execute a predetermined program, for example.

[0059] The specific area 41 is a storage area for status information indicating a specific status of the user. The specific area 41 is formed of a plurality of specific areas storing status information for determining whether or not a plurality of protected areas can be used.

[0060] The protection area 42 is a storage area for predetermined information to be protected. The protection area 42 forms a plurality of protection areas for each type of predetermined information. The protection area 42 includes a protection area for storing an electronic money balance and a protection area for storing personal information such as a name.

[0061] The information update section 43 executes a command supplied from the wireless communication section 31 and performs predetermined processing such as reading / writing data stored in the specific area 41 and the protected area 42. The information update section 43 notifies the device host 33 of the processing result of the predetermined processing as an event.

[0062] According to the control performed by the device host 33 in response to the notification of the event, the information update section 43 changes the protection area formed in the protection area 42 to the use prohibited state or the use permitted state.

[0063] Upon receiving the event notification provided from the information update unit 43, the device host 33 determines whether the protected area can be used based on the definition information 51 stored in the storage unit 34. The definition information 51 is information that defines the state of the protected area formed in the protected area 42 to be in the use-permitted state or the use-prohibited state. The device host 33 sets the protected area formed in the protected area 42 of the IC chip 32 to the use-permitted state or the use-prohibited state based on the determination result of whether it can be used. The device host 33 is configured by, for example, a CPU.

[0064] The storage unit 34 includes a nonvolatile memory and stores definition information 51 .

[0065] The definition information 51 includes specific area information, protection area information, and protection means information.

[0066] The specific area information defines which value (state) to be written to the specific area indicates that the user has no intention to use and the protected area is to be set to a use-prohibited state. The specific area information can also define which of the values ​​to be written to the specific area indicates that the user has an intention to use and the protected area is to be set to a use-permitted state.

[0067] The protection area information defines which protection area is to be set to a use-prohibited state.

[0068] The protection means information defines which protection method is to be used to set the protection area to the use-prohibited state. As the protection method, there are a method of making the protection area invisible from the reader / writer 12, that is, a method of stopping receiving all commands from the wired link and the wireless link through the IC chip 32; a method of stopping receiving all commands from the wireless link through the IC chip 32; and a method of causing the IC chip 32 to execute a command to make the protection area invisible.

[0069] Note that the definition information 51 may be pre-defined by a manufacturer or may be pre-defined by a user before use.

[0070] The reader / writer 12 includes a wireless communication section 71, a controller 72, and a storage section 73. The storage section 73 is formed with a specific area 81 which is a storage area for status information indicating a specific status of a user.

[0071] The wireless communication section 71 transmits a command supplied from the controller 72 to the device 11 , and receives a processing result of the command transmitted from the device 11 .

[0072] The controller 72 controls the operations of the various parts of the reader / writer 12 .

[0073] The controller 72 acquires a numerical value as status information indicating a specific status of the user from the specific area 81 of the storage section 73. The controller 72 outputs a command for writing the acquired numerical value indicating the specific status of the user into a specific area formed in the specific area 41 of the IC chip 32 to the wireless communication section 71 to allow the wireless communication section 71 to transmit the command to the IC chip 32.

[0074] Specifically, in the case where the reader / writer 12 is installed in the ticket gate, when the user enters the ticket gate, the controller 72 obtains a numerical value indicating that the user is in a state inside the ticket gate from the specific area 81 of the storage section 73. The controller 72 outputs a command for writing the numerical value indicating that the user is in a state inside the ticket gate to a specific area in the specific area 41 formed in the IC chip 32 to the wireless communication section 71.

[0075] Furthermore, when the user exits the ticket gate, the controller 72 obtains a numerical value indicating that the user is outside the ticket gate from the specific area 81 of the storage unit 73. The controller 72 outputs a command for writing the numerical value indicating that the user is outside the ticket gate to the specific area formed in the specific area 41 of the IC chip 32 to the wireless communication unit 71.

[0076] The storage unit 73 includes, for example, a nonvolatile memory.

[0077] <Configuration example for a specific area>

[0078] Figure 3 is a diagram showing a configuration example of a specific area of ​​an IC chip.

[0079] For example, Figure 3 As shown, the specific area 41 is formed with a ticket gate inside / outside status area 91 and a concert venue inside / outside status area 92 .

[0080] The ticket gate internal / external state area 91 is a storage area for status information indicating the user's status inside / outside the ticket gate of the station. For example, the ticket gate internal / external state area 91 stores a numerical value indicating that the user is inside the ticket gate or a numerical value indicating that the user is outside the ticket gate.

[0081] The concert venue inside / outside status area 92 is a storage area for status information indicating the use / unused status of the user's concert ticket. For example, the concert venue inside / outside status area 92 stores a numerical value indicating the use status of the concert ticket or a numerical value indicating the unused status of the concert ticket.

[0082] Figure 4 5 is a diagram showing an example of the correspondence relationship between the numerical value of the specific area and the user's intention to use the protection area. Such a correspondence relationship is defined by the definition information 51.

[0083] like Figure 4As shown in the first row of , it is defined that, in the case where the numerical value of the specific area indicates the state inside the ticket gate, the user has no intention to use, and the protected area as the protection object will be set to the use prohibited state. In addition, as shown in the second row, it is defined that, in the case where the numerical value of the specific area indicates the state outside the ticket gate, the user has the intention to use, and the protected area as the protection object will be set to the use allowed state.

[0084] like Figure 4 As shown in the third row of the definition, it is defined that in the case where the value of the specific area indicates the state inside the concert venue, the user has no intention to use, and the protected area as the protection object will be set to the use-prohibited state. In addition, as shown in the fourth row, it is defined that in the case where the value of the specific area indicates the state outside the concert venue, the user has the intention to use, and the protected area as the protection object will be set to the use-permitted state

[0085] <Device Operation>

[0086] Here, we will refer to Figure 5 Flowchart description in Figure 2 The processing is performed by the device 11.

[0087] For example, in Figure 5 Before the process of starts, the wireless communication section 71 of the reader / writer 12 is in a state of performing polling. When the user brings the device 11 close to the reader / writer 12, a response to the reception of the polling is sent from the wireless communication section 31 of the device 11 to the reader / writer 12.

[0088] In the case where a response to the polling has been sent from the device 11, the controller 72 of the reader / writer 12 acquires a numerical value representing the specific status of the user from the specific area 81 and outputs the numerical value to the wireless communication section 71. The wireless communication section 71 sends a command for writing the numerical value representing the specific status of the user to the device 11.

[0089] The wireless communication section 31 of the device 11 receives the command that has been transmitted from the reader / writer 12, and outputs the command to the information updating section 43. In the device 11 and the reader / writer 12, such processing is performed as Figure 5 Preprocessing of the processing.

[0090] In step S31 , the information updating section 43 updates the numerical value of the specific area in the specific area 41 formed in the IC chip 32 by executing the command supplied from the wireless communication section 31 .

[0091] In step S32 , the information update section 43 notifies the device host 33 that the value of the specific area in the specific area 41 formed in the IC chip 32 has been updated.

[0092] In step S33 , the device host 33 determines whether the value of the specific area has become a value corresponding to the state of “no intention to use” based on the definition information 51 of the storage unit 34 .

[0093] In the event that it is determined in step S33 that the numerical value of the specific area has become a numerical value corresponding to the state of “no intention to use”, the process proceeds to step S34 .

[0094] In step S34, based on the definition information 51 of the storage unit 34, the device host 33 sets the protected area formed in the protected area 42 and specified by the "protected area information" to a use-prohibited state by using the method specified by the "protection means information". For example, the protected area formed in the protected area 42 of the IC chip 32 is set to a use-prohibited state based on a numerical value indicating the internal state of the ticket gate.

[0095] When it is determined in step S33 that the numerical value of the specific area has not changed to any numerical value that indicates a state of "no intention to use", the processing in step S34 is skipped, and the processing of the device 11 ends. For example, the protection area formed in the protection area 42 of the IC chip 32 is maintained in the use-permitted state according to the numerical value indicating the state outside the ticket gate.

[0096] As described above, the protected area can be brought into a use-prohibited state according to a specific state of the user.

[0097] This configuration allows the protected area to be set to a use-prohibited state while the user is inside the ticket gate, and thus can prevent skimming while the user is inside the ticket gate or riding a train.

[0098] <2. Second Embodiment (Example of Further Determining Usability Based on Time Period)>

[0099] <Configuration example of device>

[0100] Figure 6 is a block diagram showing a second configuration example of the device.

[0101] exist Figure 6 In the device 11, the protected area is set to the use prohibited state only during a specific period such as rush hour.

[0102] exist Figure 6 The components shown in the figure are the same as those already mentioned in the reference Figure 2 The same components as those described above are denoted by the same reference numerals, and their repeated description will be omitted as appropriate.

[0103] Figure 6 The configuration shown is similar to Figure 2The configuration of the device 11 is different in that a time information acquisition unit 101 is added. In addition, the time period information is added to the definition information 51 of the storage unit 34. Figure 6 In the example of , also considering the current time, it is determined whether the protected area is to be set to the use-permitted state or the use-prohibited state.

[0104] The time information acquisition unit 101 acquires the time information inside the device 11 , and outputs the acquired time information to the device host 33 .

[0105] In the definition information 51, time period information indicating a high time period such as peak time is defined in association with a specific area, during which time period the protected area is to be set to a use prohibited state.

[0106] When the time information in the device 11 and supplied from the time information acquisition unit 101 falls within the range specified by the defined time period information, the device host 33 sets the protected area to the use permitted state.

[0107] <Device Operation>

[0108] Figure 7 is described by Figure 6 Flowchart of the processing performed by the device.

[0109] Figure 7 The processing in steps S51 to S53 is the same as Figure 5 The processing in steps S31 to S33 is the same as that in FIG. 1 , and thus a description thereof will be omitted.

[0110] When it is determined in step S53 that the numerical value of the specific area has been changed to a numerical value corresponding to the state of “no intention to use”, in step S54, the time information acquisition unit 101 acquires the time information inside the device 11 and outputs the acquired time information to the device host 33.

[0111] In step S55 , the device host 33 determines whether the time information provided from the time information acquisition section 101 and inside the device 11 falls within the range specified by the defined “time period information”.

[0112] In the event that it is determined in step S55 that the time information inside the device 11 falls within the range specified by the "period information", the process proceeds to step S56.

[0113] In step S56 , the device host 33 sets the protected area formed in the protected area 42 and specified by the “protected area information” to a use-prohibited state by using the method specified by the “protection means” based on the definition information 51 of the storage unit 34 .

[0114] When it is determined in step S53 that the numerical value of the specific area has not changed to any numerical value corresponding to the state of "no intention to use", the processing in steps S54 to S56 is skipped, and the processing of the device 11 ends. In the case where it is determined in step S55 that the time information inside the device 11 does not fall within the range specified by the "time period information", similarly, the processing of the device 11 ends.

[0115] As described above, within the range specified by the "time period information" indicating the peak hours or the like, the protected area can be set to the use prohibited state according to the specific state of the user.

[0116] <3. Third Embodiment (Example of Determining Whether Usability Is Available Further Based on the User's Location)>

[0117] <Configuration example of device>

[0118] Figure 8 is a block diagram showing a third configuration example of the device.

[0119] exist Figure 8 In the device 11, the protection area is set to the use-prohibited state only in a specific area such as an urban area and a specific place.

[0120] exist Figure 8 The components shown in the figure are the same as those already mentioned in the reference Figure 2 The same constituent elements as those described are denoted by the same reference numerals, and their repeated description will be omitted as appropriate.

[0121] Figure 8 The configuration shown is similar to Figure 2 The configuration of the device 11 is different in that a position information acquisition unit 111 is added. In addition, specific position information is added to the definition information 51 of the storage unit 34. Figure 8 In the example of , the user's position is also taken into consideration to determine whether the protected area is to be set to the use-permitted state or the use-prohibited state.

[0122] The position information acquisition section 111 acquires position information about the device 11 by using, for example, GPS, etc. The position information acquisition section 111 acquires position information about the device 11 and outputs the acquired position information to the device host 33 .

[0123] In the definition information 51, specific location information indicating a specific area such as an urban area and a specific place in which the protection area is to be set to a use-prohibited state is defined.

[0124] When the position information about the device 11 supplied from the position information acquisition section 111 falls within the range specified by the defined specific position information, the device host 33 sets the protection area to the use prohibited state.

[0125] <Device Operation>

[0126] Fig. 9 is described by Figure 8 Flowchart of the processing performed by the device.

[0127] Fig. 9 The processing in steps S81 to S83 is the same as Figure 5 The processing in steps S31 to S33 is the same as that in FIG. 1 , and thus a description thereof will be omitted.

[0128] When it is determined in step S83 that the numerical value of the specific area has become a numerical value corresponding to the state of “no intention to use”, in step S84, the location information acquisition unit 111 acquires location information related to the device 11 and outputs the acquired location information to the device host 33.

[0129] In step S85 , the device host 33 determines whether the position information about the device 11 provided from the position information acquisition section 111 falls within the range specified by the defined “specific position information”.

[0130] In the event that it is determined in step S85 that the position information regarding the device 11 falls within the range specified by the "specific position information", the process proceeds to step S86.

[0131] In step S86, the device host 33 sets the protected area formed in the protected area 42 and specified by the "protected area information" to a use-prohibited state by using the method specified by the "protection means information" based on the definition information 51 of the storage unit 34.

[0132] When it is determined in step S83 that the numerical value of the specific area has not changed to any numerical value corresponding to the state of "no intention to use", the processing in steps S84 to S86 is skipped, and the processing of the device 11 ends. In the case where it is determined in step S85 that the position information related to the device 11 is not within the range specified by the "specific position information", similarly, the processing of the device 11 ends.

[0133] As described above, within the range specified by the "specific position information" indicating a specific place or the like, the protected area can be set to a use-prohibited state according to the specific state of the user.

[0134] <4. Fourth Embodiment (Example of Determining Whether Usability Is Available Further Based on the Numerical Value of Information Related to the Protection Area)>

[0135] <Configuration example of device>

[0136] Fig.10 is a block diagram showing a fourth configuration example of the device.

[0137] exist Fig.10 In the device 11, the protected area is set to a use-prohibited state according to the value of the information recorded in the protected area. Examples of the value of the information recorded in the protected area include an electronic money balance and the like.

[0138] exist Fig.10 The components shown in the figure are the same as those already mentioned in the reference Figure 2 The same constituent elements as those described are denoted by the same reference numerals, and their repeated description will be omitted as appropriate.

[0139] Fig.10 Configuration and Figure 2 The configuration of the device 11 is different in that a reference protection area execution unit 121 is added. In addition, a protection value threshold is added to the definition information 51 of the storage unit 34. Fig.10 In the example of , also in view of the size of the value stored in the protected area, it is determined whether the protected area is to be set to the use permitted state or the use prohibited state.

[0140] The reference protected area execution unit 121 refers to the protected area as the protection target, acquires the value of the information recorded in the protected area, and outputs the acquired value of the information to the device host 33 .

[0141] The definition information 51 defines a protection value threshold value which is a threshold value compared with the numerical value of information recorded in the protection area when determining whether the protection area is to be set to the use prohibited state.

[0142] When the numerical value of the information provided from the reference protection area execution unit 121 is larger than the defined protection value threshold, the device host 33 sets the protection area to enter the use prohibited state.

[0143] <Device Operation>

[0144] Fig.11 is described by Fig.10 Flowchart of the processing performed by the device.

[0145] Fig.11 The processing in steps S111 to S113 is the same as Figure 5 The processing in steps S31 to S33 is the same as that in FIG. 1 , and thus a description thereof will be omitted.

[0146] When it is determined in step S113 that the value of the specific area has become a value corresponding to the state of "no intention to use", in step S114, the reference protection area execution unit 121 obtains the value of the information recorded in the protection area and outputs the obtained value to the device host 33.

[0147] In step S115 , the device host 33 determines whether the numerical value provided from the position information acquisition unit 111 is greater than a defined “protection value threshold”.

[0148] When it is determined in step S115 that the numerical value is greater than the "protection value threshold", the process proceeds to step S116.

[0149] In step S116 , the device host 33 sets the protected area formed in the protected area 42 and specified by the “protected area information” to a use-prohibited state by using the method specified by the “protection means” based on the definition information 51 of the storage unit 34 .

[0150] When it is determined in step S113 that the numerical value of the specific area has not been changed to any numerical value corresponding to the state of "no intention to use", the processing in steps S114 to S116 is skipped, and the processing of the device 11 ends.

[0198] Fig.16 The configuration shown is similar to Figure 2 The configuration of the device 11. In addition, a counter and a threshold value are added to the definition information 51 of the storage unit 34. Fig.16 In the example of , the number of times a specific area is used is also taken into consideration, the number of times is counted by a counter, and it is determined whether the protected area is set to the use-permitted state or the use-prohibited state.

[0199] In the definition information 51 , a counter for counting the number of times of use of a specific area and a threshold value of the number of times of use for setting a protected area to a use-prohibited state are defined in association with the specific area.

[0200] When the value of the specific area has become a value corresponding to a state where the user has no intention of use, the device host 33 increments a counter included in the definition information 51 and associated with the specific area by 1. When the number of uses indicated by the counter is equal to or greater than a threshold value, the device host 33 sets the protected area to a use-prohibited state.
