Summary of the Invention

Problems to be Solved by the Invention

[0004] In the technique described in Patent Document 1, it is possible to prevent personal information of the user from flowing out to the outside from the country or region where the user resides when storing data. In the following description, "data flowing out to the outside from the country or region where the user resides" is referred to as "data cross-border". Here, when collecting data that does not directly correspond to personal information but can indirectly identify an individual, data that can only indirectly identify an individual can be effectively utilized by cross-bordering the data in a state where the individual cannot be identified. However, in the technique described in Patent Document 1, when the output data of the electronic device may contain personal information, the output data of the electronic device is stored in the country or region where the user resides all at once, so data cross-bordering cannot be performed.

Means for Solving the Problems

[0005] One aspect of the present disclosure is that a first application server device disposed in a first region causes a first file server device disposed in the first region to store in association the personal information of a first user residing in the first region and association data associated with a first electronic device owned by the first user; the first electronic device stores the association data; the first electronic device transmits, to a second file server device disposed in a second region different from the first region, first data that does not include the personal information of the first user among the information output by the first electronic device and that indicates the state of the first electronic device, and the association data; the second file server device stores the first data and the association data in association with each other; and the first application server device acquires the first data from the second file server device using the association data. This is a data management method.

[0006] Another aspect of the present disclosure is a data management system including: a first file server device that stores in association the personal information of a first user residing in a first region and association data associated with a first electronic device owned by the first user; a second file server device disposed in a second region different from the first region, that stores in association first data that does not include the personal information of the first user among the information output by the first electronic device and that indicates the state of the first electronic device, and the association data; and a first application server device that acquires the first data from the second file server device using the association data.

Mode for Carrying Out the Invention

[0008] Hereinafter, this embodiment will be described with reference to the drawings. FIG. 1 is a diagram showing an example of the configuration of a data management system 100 according to this embodiment. The data management system 100 includes a first application server device 1, a first database server device 2, a first projector 3, a personal computer 4, a second application server device 5, a second database server device 6, and a second projector 7.

[0009] The first application server device 1, the first database server device 2, the first projector 3, and the personal computer 4 are arranged in a first area AR1. The first application server device 1, the first database server device 2, the first projector 3, and the personal computer 4 are communicably connected via a first network NW1. The first area AR1 corresponds to an example of "the first area". In this embodiment, "the first area" means "the first country or the first region". In other words, in this embodiment, "area" means "country or region". The first network NW1 is, for example, a part of the Internet. In other words, it is a network arranged in the first area AR1 among the Internet.

[0010] In addition, the second application server device 5, the second database server device 6, and the second projector 7 are arranged in a second area AR2 different from the first area AR1. The second application server device 5, the second database server device 6, and the second projector 7 are communicably connected via the second network NW2. The second area AR2 corresponds to an example of the "second area". In the present embodiment, the "second area" means the "second country or second region". The second network NW2 is, for example, a part of the Internet. In other words, it is a network arranged in the second area AR2 among the Internet. The second network NW2 is communicably connected to the first network NW1.

[0011] Since the second network NW2 is communicably connected to the first network NW1, each of the first application server device 1, the first database server device 2, the first projector 3, and the personal computer 4 arranged in the first area AR1 and each of the second application server device 5, the second database server device 6, and the second projector 7 arranged in the second area AR2 are communicably connected to each other. In the present embodiment, the case where each of the first network NW1 and the second network NW2 is a part of the Internet will be described, but the embodiment is not limited thereto. Each of the first network NW1 and the second network NW2 may be, for example, a WAN (Wide Area Network).

[0012] The first database server device 2 corresponds to an example of the "first file server device". The second database server device 6 corresponds to an example of the "second file server device". The first projector 3 corresponds to an example of the "first electronic device". The second projector 7 corresponds to an example of the "second electronic device". The personal computer 4 corresponds to an example of the "terminal device".

[0013] In the following description, for convenience, the first application server device 1 may be described as the "first AP server device 1", and the second application server device 5 may be described as the "second AP server device 5". Also, the first database server device 2 may be described as the "first DB server device 2", and the second database server device 6 may be described as the "second DB server device 6". Also, the first projector 3 may be described as the "first PJ3", and the second projector 7 may be described as the "second PJ7". Also, the personal computer 4 may be described as the "PC4".

[0014] Next, with reference to FIG. 1, the configurations of the first AP server device 1, the first DB server device 2, the first PJ3, the PC4, the second AP server device 5, the second DB server device 6, and the second PJ7 will be described.

[0015] First, the configuration of the first AP server device 1 will be described. The first AP server device 1 is disposed in the first area AR1 and provides various services regarding the information output by the first PJ3 to the first user U1. The first user U1 is a user residing in the first area AR1 and owns the first PJ3 and the PC4. The first AP server device 1 includes a first control unit 11. The first control unit 11 controls each part of the first AP server device 1. The first control unit 11 includes a first processor 11A and a first memory 11B.

[0016] The first memory 11B is a storage device that non-volatilely stores programs and data executed by the first processor 11A. The first memory 11B is composed of a magnetic storage device, a semiconductor memory element such as a flash ROM (Read Only Memory), or other types of non-volatile storage devices. Further, the first memory 11B may include a RAM (Random Access Memory) that constitutes the work area of the first processor 11A. The first memory 11B stores data processed by the first control unit 11 and the first control program PG1 and the like executed by the first processor 11A.

[0017] The first processor 11A may be composed of a single processor or may be configured such that a plurality of processors function as the first processor 11A. The first processor 11A executes the first control program PG1 to control each part of the first AP server device 1.

[0018] The first processor 11A may be composed of a SoC (System on Chip) integrated with a part or all of the first memory 11B and other circuits. Further, the first processor 11A may be configured by a combination of a CPU (Central Processing Unit) that executes a program and a DSP (Digital Signal Processor) that executes predetermined arithmetic processing. All of the functions of the first processor 11A may be implemented in hardware or may be configured using a programmable device.

[0019] In the following description, a case will be described in which the first processor 11A reads and executes the first control program PG1 stored in the first memory 11B to control each part of the first AP server device 1. The first control unit 11 functions as a storage instruction unit 111, a first acquisition unit 112, a second acquisition unit 113, and a transmission execution unit 114. Specifically, the first processor 11A reads and executes the first control program PG1 stored in the first memory 11B, thereby functioning as the storage instruction unit 111, the first acquisition unit 112, the second acquisition unit 113, and the transmission execution unit 114.

[0020] The storage instruction unit 111 causes the first DB server device 2 to store the personal information of the first user U1 in association with the specific correspondence information DP. The first user U1 is a user who resides in the first area AR1. Also, the first user U1 is a user who holds and uses the first PJ3. Also, the first user U1 is a user who owns the PC4. The specific correspondence information DP is data associated with the first PJ3 and does not correspond to the personal information of users such as the first user U1. The specific correspondence information DP is information associated with, for example, a corporation such as a stock company that owns the first PJ3, or an individual. Also, as will be described with reference to FIG. 2, when the first user U1 performs user registration for the first PJ3, the first control unit 11 generates a random number and assigns the generated random number as the specific correspondence information DP. Thus, since the specific correspondence information DP is a random number generated by the first control unit 11, the specific correspondence information DP is not regarded as personal information by the law regarding the protection of personal information in the first area AR1. Therefore, by using the specific correspondence information DP, for example, the first acquisition unit 112 can acquire the first data D1 from the second DB server device 6 disposed in the second area AR2. The specific correspondence information DP corresponds to an example of "association data".

[0021] The first acquisition unit 112 acquires the first data D1 from the second DB server device 6 using the specific correspondence information DP. The first data D1 is data that does not include the personal information of the first user U1 among the information output by the first PJ3, and is data indicating the state of the first PJ3. The first data D1 includes, for example, data such as the usage time of the light source, the resolution of the input source, and the error history in the first PJ3. The processing by the first acquisition unit 112 will be further described with reference to FIG. 3. The first data D1 will be further described with reference to FIG. 5.

[0022] The second acquisition unit 113 acquires the second data D2 from the first PJ3. The second data D2 is data that includes the personal information of the first user U1 among the information output by the first PJ3, excluding the first data D1. The second data D2 includes at least a part of the setting information of the first PJ3. Also, the second data D2 includes at least a part of the image information of the first PJ3.

[0023] The second data D2 is set, for example, based on the law regarding the protection of personal information in the first area AR1. In other words, the second data D2 is information that is or may be the subject of protection by the law regarding the protection of personal information in the first area AR1. The second data D2 includes, for example, data such as the user ID used for the authentication of the first user U1 in the first AP server device 1, the password, the email address of the first PJ3, and the captured image of the camera equipped in the first PJ3. The reason why the captured image of the camera equipped in the first PJ3 is the subject of protection of personal information is that the captured image may include the image of a user such as the first user U1. The second data D2 will be further described with reference to FIG. 5.

[0024] In addition, the memory instruction unit 111 causes the first DB server device 2 to store first destination information indicating a first destination R1 that is a transmission destination to which the first PJ3 transmits the second data D2 and is included in the first area AR1. For example, in response to a request from the PC 4, the memory instruction unit 111 causes the first DB server device 2 to store first destination information indicating the first destination R1 that is a transmission destination to which the first PJ3 transmits the second data D2. In this case, the first destination R1 is the PC 4, and the first destination information is the email address information of the PC 4.

[0025] The transmission execution unit 114 transmits the second data D2 acquired by the second acquisition unit 113 to the first DB server device 2 in association with the specific correspondence information DP. The memory instruction unit 111 causes the first DB server device 2 to store the second data D2 in association with the specific correspondence information DP.

[0026] Next, the configuration of the first DB server device 2 will be described. The first DB server device 2 stores the second data D2 in association with the specific correspondence information DP according to the instruction of the first AP server device 1. The first DB server device 2 includes a second control unit 21. The second control unit 21 controls each unit of the first DB server device 2. The second control unit 21 includes a second processor 21A and a second memory 21B.

[0027] The second memory 21B is a storage device that non-volatilely stores programs and data executed by the second processor 21A. The second memory 21B is composed of a magnetic storage device, a semiconductor memory element such as a flash ROM, or other types of non-volatile storage devices. Further, the second memory 21B may include a RAM that constitutes a work area of the second processor 21A. The second memory 21B stores data processed by the second control unit 21 and a second control program PG2 executed by the second processor 21A, etc.

[0028] The second processor 21A may be composed of a single processor or may be configured such that a plurality of processors function as the second processor 21A. The second processor 21A executes the second control program PG2 to control each part of the first DB server device 2.

[0029] The second processor 21A may be composed of a SoC integrated with a part or all of the second memory 21B and other circuits. Also, the second processor 21A may be configured by a combination of a CPU that executes a program and a DSP that executes predetermined arithmetic processing. All functions of the second processor 21A may be implemented in hardware or may be configured using a programmable device.

[0030] In the following description, the case where the second processor 21A controls each part of the first DB server device 2 by reading and executing the second control program PG2 stored in the second memory 21B will be described.

[0031] The second control unit 21 stores the personal information of the first user U1 in association with the specific correspondence information DP according to the instruction of the storage instruction unit 111 of the first AP server device 1. Also, the second control unit 21 receives the second data D2 and the specific correspondence information DP transmitted by the transmission execution unit 114 of the first AP server device 1. Then, the second control unit 21 stores the second data D2 in association with the specific correspondence information DP according to the instruction of the storage instruction unit 111 of the first AP server device 1.

[0032] Also, the second control unit 21 receives the first destination information transmitted by the transmission execution unit 114 of the first AP server device 1. The first destination information indicates the first destination R1 which is the destination to which the first PJ3 transmits the second data D2. The first destination R1 is, for example, PC4, and the first destination information is the email address information of PC4. Also, the second control unit 21 transmits the first destination information to the first PJ3 in response to a request from the first PJ3.

[0033] Next, the configuration of the first PJ3 will be described. The first PJ3 acquires a projected image from a source device (not shown) and projects the projected image onto a projection surface such as a screen. The first PJ3 also includes a camera (not shown) and captures an image of the projection surface onto which the projected image is projected using the camera. The first PJ3 includes a third control unit 31. The third control unit 31 controls each part of the first PJ3. The third control unit 31 includes a third processor 31A and a third memory 31B.

[0034] The third memory 31B is a storage device that non-volatilely stores programs and data executed by the third processor 31A. The third memory 31B is constituted by a magnetic storage device, a semiconductor memory element such as a flash ROM, or other types of non-volatile storage devices. The third memory 31B may also include a RAM that constitutes a work area for the third processor 31A. The third memory 31B stores data processed by the third control unit 31 and a third control program PG3 executed by the third processor 31A.

[0035] The third processor 31A may be constituted by a single processor or may be configured such that a plurality of processors function as the third processor 31A. The third processor 31A executes the third control program PG3 to control each part of the first PJ3.

[0036] The third processor 31A may be constituted by a SoC integrated with a part or all of the third memory 31B and other circuits. The third processor 31A may also be configured by a combination of a CPU that executes a program and a DSP that executes predetermined arithmetic processing. All functions of the third processor 31A may be implemented in hardware or may be configured using a programmable device.

[0037] In the following description, a case where the third processor 31A controls each part of the first PJ3 by reading and executing a third control program PG3 stored in the third memory 31B will be described. The third control unit 31 functions as a first transmission unit 311, a second transmission unit 312, and a third transmission unit 313. Specifically, the third processor 31A functions as the first transmission unit 311, the second transmission unit 312, and the third transmission unit 313 by reading and executing a third control program PG3 stored in the third memory 31B.

[0038] The first transmission unit 311 transmits the first data D1 and the specific correspondence information DP to the second DB server device 6. The first data D1 is data that does not include the personal information of the first user U1 among the information output by the first PJ3 and that indicates the state of the first PJ3. The first transmission unit 311 transmits the first data D1 and the specific correspondence information DP to the second DB server device 6 via, for example, the second AP server device 5.

[0039] The second transmission unit 312 transmits the second data D2 to the first transmission destination R1 based on the first transmission destination information acquired from the first DB server device 2. The first transmission destination information indicates the first transmission destination R1. In other words, the second transmission unit 312 acquires, for example, from the first DB server device 2, the first transmission destination information indicating the first transmission destination R1 via the second AP server device 5. Then, the second transmission unit 312 transmits the second data D2 to the first transmission destination R1 based on the first transmission destination information. For example, when the first transmission destination R1 is PC4, the first transmission destination information is the email address of PC4. Then, the second transmission unit 312 transmits the second data D2 to PC4 as an attachment to an email, for example.

[0040] The third transmission unit 313 transmits the personal information of the first user U1 to the second transmission destination R2 included in the first area AR1 based on the second transmission destination information received from the second AP server device 5. The second transmission destination information indicates the second transmission destination R2. The second destination R2 is, for example, a schematic smartphone owned by the first user U1. In this case, the second destination information is, for example, the email address of the smartphone owned by the first user U1. Then, the third transmission unit 313 transmits, for example, the personal information of the first user U1 to the schematic smartphone owned by the first user U1 as an attachment file of an email.

[0041] Next, the configuration of the PC 4 will be described. The PC 4 is a personal computer owned by the first user U1. The PC 4 is communicably connected to a schematic keyboard, mouse, etc., and receives operations from the first user U1. Then, the PC 4 performs, for example, user registration request processing for the first AP server device 1 based on the received operations. The PC 4 includes a fourth control unit 41. The fourth control unit 41 controls each part of the PC 4. The fourth control unit 41 includes a fourth processor 41A and a fourth memory 41B.

[0042] The fourth memory 41B is a storage device that non-volatily stores programs and data executed by the fourth processor 41A. The fourth memory 41B is composed of a magnetic storage device, a semiconductor memory element such as a flash ROM, or other types of non-volatile storage devices. Also, the fourth memory 41B may include a RAM that constitutes the work area of the fourth processor 41A. The fourth memory 41B stores data processed by the fourth control unit 41 and the fourth control program PG4 executed by the fourth processor 41A, etc.

[0043] The fourth processor 41A may be composed of a single processor or may be configured such that a plurality of processors function as the fourth processor 41A. The fourth processor 41A executes the fourth control program PG4 to control each part of the PC 4.

[0044] The fourth processor 41A may be composed of a system-on-chip (SoC) integrated with part or all of the fourth memory 41B and other circuits. Alternatively, the fourth processor 41A may be composed of a combination of a CPU that executes programs and a DSP that executes predetermined arithmetic processing. All of the functions of the fourth processor 41A may be implemented in hardware, or may be configured using a programmable device.

[0045] In the following description, a case will be described in which the fourth processor 41A controls each part of the PC4 by reading and executing the fourth control program PG4 stored in the fourth memory 41B. The fourth control unit 41 requests user registration of the first user U1 from the first AP server device 1. The process of user registration will be further described with reference to FIG. 2.

[0046] Also, after the user registration to the first AP server device 1 is completed, when the personal authentication by the first AP server device 1 is successful, the fourth control unit 41 can receive various services from the first AP server device 1. The personal authentication by the first AP server device 1 will be further described with reference to FIG. 3.

[0047] Next, the configuration of the second AP server device 5 will be described. In the present embodiment, the second AP server device 5 functions as a window device for transmitting and receiving data to and from the second DB device 6. For example, when the first PJ3 stores the first data D1 in the second DB device 6 in association with the specific correspondence information DP, the first PJ3 and the second AP server device 5 execute the following process. First, the first PJ3 transmits to the second AP server device 5 the first data D1, the specific correspondence information DP, and information requesting that the first data D1 be stored in the second DB device 6 in association with the specific correspondence information DP. Then, when the second AP server device 5 receives this request, it stores the first data D1 in the second DB device 6 in association with the specific correspondence information DP. The second AP server device 5 includes a fifth control unit 51. The fifth control unit 51 controls each part of the second AP server device 5. The fifth control unit 51 includes a fifth processor 51A and a fifth memory 51B.

[0048] The fifth memory 51B is a storage device that stores programs and data executed by the fifth processor 51A in a non-volatile manner. The fifth memory 51B is composed of a magnetic storage device, a semiconductor memory element such as a flash ROM, or other types of non-volatile storage devices. Further, the fifth memory 51B may include a RAM that constitutes the work area of the fifth processor 51A.

[0049] The fifth processor 51A may be composed of a single processor, or may be configured such that a plurality of processors function as the fifth processor 51A. The fifth processor 51A executes the fifth control program PG5 to control each part of the second AP server device 5.

[0050] The fifth processor 51A may be composed of a SoC integrated with a part or all of the fifth memory 51B and other circuits. Further, the fifth processor 51A may be configured by a combination of a CPU that executes a program and a DSP that executes predetermined arithmetic processing. All of the functions of the fifth processor 51A may be implemented in hardware, or may be configured using a programmable device.

[0051] In the following description, a case will be described in which the fifth processor 51A reads and executes the fifth control program PG5 stored in the fifth memory 51B to control each part of the second AP server device 5. The fifth control unit 51 notifies, for example, in response to a request from the PC4, the first PJ3 of the second destination information indicating the second destination R2 included in the first area AR1. The processing of each device of the data management system 100 in this case will be described in detail with reference to FIG. 4.

[0052] Next, the configuration of the second DB server device 6 will be described. The second DB server device 6 stores the first data D1 in association with the specific correspondence information DP according to the instruction of the second AP server device 5. The second DB server device 6 includes a sixth control unit 61. The sixth control unit 61 controls each part of the second DB server device 6. The sixth control unit 61 includes a sixth processor 61A and a sixth memory 61B.

[0053] The sixth memory 61B is a storage device that stores programs and data executed by the sixth processor 61A in a non-volatile manner. The sixth memory 61B is composed of a magnetic storage device, a semiconductor memory element such as a flash ROM, or other types of non-volatile storage devices. Further, the sixth memory 61B may include a RAM that constitutes the work area of the sixth processor 61A. The sixth memory 61B stores data processed by the sixth control unit 61 and the sixth control program PG6 executed by the sixth processor 61A, etc.

[0054] The sixth processor 61A may be composed of a single processor, or a configuration in which a plurality of processors function as the sixth processor 61A. The sixth processor 61A executes the sixth control program PG6 to control each part of the second DB server device 6.

[0055] The sixth processor 61A may be composed of a SoC integrated with a part or all of the sixth memory 61B and other circuits. Further, the sixth processor 61A may be composed of a combination of a CPU that executes a program and a DSP that executes predetermined arithmetic processing. All the functions of the sixth processor 61A may be implemented in hardware, or may be configured using a programmable device.

[0056] In the following description, a case will be described where the sixth processor 61A controls each part of the second DB server device 6 by reading and executing the sixth control program PG6 stored in the sixth memory 61B. The sixth control unit 61 stores the first data D1 in the sixth memory 61B in association with the specific correspondence information DP according to an instruction from the second AP server device 5. The first data D1 is data that does not include the personal information of the first user U1 among the information output by the first PJ3 and that indicates the state of the first PJ3. The first data D1 includes, for example, data such as the usage time of the light source, the resolution of the input source, and the error history in the first PJ3.

[0057] Next, the configuration of the second PJ7 will be described. The second PJ7 acquires a projection image from a source device (not shown) and projects the projection image onto a projection surface such as a screen. The second PJ7 also includes a camera (not shown) and images the projection surface onto which the projection image is projected using the camera. The second PJ7 includes a seventh control unit 71. The seventh control unit 71 controls each part of the second PJ7. The seventh control unit 71 includes a seventh processor 71A and a seventh memory 71B.

[0058] The seventh memory 71B is a storage device that non-volatilely stores programs and data executed by the seventh processor 71A. The seventh memory 71B is composed of a magnetic storage device, a semiconductor memory element such as a flash ROM, or other types of non-volatile storage devices. The seventh memory 71B may also include a RAM that constitutes the work area of the seventh processor 71A. The seventh memory 71B stores data processed by the seventh control unit 71 and the seventh control program PG7 executed by the seventh processor 71A, etc.

[0059] The seventh processor 71A may be composed of a single processor, or may be configured such that a plurality of processors function as the seventh processor 71A. The seventh processor 71A executes the seventh control program PG7 to control each part of the second PJ7.

[0060] The seventh processor 71A may be composed of a SoC integrated with part or all of the seventh memory 71B and other circuits. Also, the seventh processor 71A may be composed of a combination of a CPU that executes a program and a DSP that executes predetermined arithmetic processing. All the functions of the seventh processor 71A may be implemented in hardware, or may be configured using a programmable device.

[0061] In the following description, the case where the seventh processor 71A controls each part of the second PJ7 by reading and executing the seventh control program PG7 stored in the seventh memory 71B will be described. The seventh control unit 71 stores the specific correspondence information DP in the seventh memory 71B. The specific correspondence information DP is, for example, identification information associated with both the first PJ3 and the second PJ7. Also, the specific correspondence information DP is identification information that identifies a corporation such as a stock company that owns the first PJ3, or an individual. Thus, for example, a corporation such as a stock company that owns the second PJ7, or an individual, is the same as a corporation such as a stock company that owns the first PJ3, or an individual. In other words, for example, one stock company, or one individual, owns the first PJ3 and the second PJ7.

[0062] Also, the seventh control unit 71 transmits the third data D3 and the specific correspondence information DP to the second DB server device 6. The third data D3 is data that does not include the personal information of the second user U2 among the information output by the second PJ7, and is data indicating the state of the second PJ7. The second user U2 is a user who holds or uses the second PJ7. The third data D3 includes, for example, data such as the usage time of the light source, the resolution of the input source, and the error history in the second PJ7.

[0063] The seventh control unit 71 causes the second DB server device 6 to store the third data D3 and the specific correspondence information DP in association with each other via, for example, the second AP server device 5. In this case, first, the seventh control unit 71 transmits to the second AP server device 5 information for requesting the second DB server device 6 to store the third data D3, the specific correspondence information DP, and the information for associating and storing the third data D3 and the specific correspondence information DP in association with each other. Then, in response to this request, the second AP server device 5 causes the second DB server device 6 to store the third data D3 received from the second PJ7 and the specific correspondence information DP received from the second PJ7 in association with each other. Further, the second DB server device 6 stores the third data D3 and the specific correspondence information DP in association with each other in accordance with an instruction from the second AP server device 5.

[0064] Next, with reference to FIG. 2, a sequence of user registration to the first AP server device 1 will be described. FIG. 2 is a diagram showing an example of a sequence of user registration by a first user U1 to the first AP server device 1. As shown in FIG. 2, first, in step S101, in response to an operation on the PC4 by the first user U1, the PC4 requests the first AP server device 1 to perform user registration of the first user U1 as the holder or user of the first PJ3. At this time, the PC4 transmits a user ID and a password to the first AP server device 1.

[0065] If the specific correspondence information DP corresponding to the owner of the first PJ3 held or used by the first user U1 has already been determined, the PC4 transmits the specific correspondence information DP to the first AP server device 1. The case where the specific correspondence information DP corresponding to the owner of the first PJ3 has already been determined is, for example, the following case. That is, the owner of the first PJ3, for example, a corporation such as a stock company, owns a plurality of projectors including the first PJ3. And among the plurality of projectors, when a user who holds or uses a projector other than the first PJ3 has already completed user registration to the first AP server device 1.

[0066] Next, in step S103, the storage instruction unit 111 of the first AP server device 1 causes the first DB server device 2 to store the user ID and password as personal information of the first user U1 in association with the specific correspondence information DP. When the specific correspondence information DP corresponding to the owner of the first PJ3 has not been determined, the first control unit 11 of the first AP server device 1 generates a random number and assigns the generated random number as the specific correspondence information DP corresponding to the owner of the first PJ3. Next, in step S105, the first AP server device 1 notifies the PC4 that the user registration has been completed. At this time, the first AP server device 1 notifies the PC4 of the specific correspondence information DP.

[0067] Next, in step S107, the PC4 stores the specific correspondence information DP in the first PJ3. Next, in step S109, the first transmission unit 311 of the first PJ3 transmits the specific correspondence information DP, the first data D1, and the serial number NS of the first PJ3 to the second DB server device 6 via the second AP server device 5. The serial number NS of the first PJ3 is a serial number that can identify the first PJ3, for example, a manufacturing number. Note that the process of step S109 is executed each time the first data D1 is generated or updated. The second DB server device 6 receives the specific correspondence information DP, the first data D1, and the serial number NS of the first PJ3, and stores the specific correspondence information DP, the first data D1, and the first PJ3 in the sixth memory 61B. Then, the process ends.

[0068] In this way, the first data D1 of the first PJ3 is stored in the second DB server device 6 in association with the specific correspondence information DP and the serial number NS of the first PJ3. In addition, when the serial number NS of the first PJ3 is defined as personal information by the law regarding the protection of personal information in the first area AR1, the first PJ3 encrypts the serial number NS of the first PJ3 and transmits it to the second DB server device 6. The encryption key used for encrypting the serial number NS of the first PJ3 is generated by the first AP server device 1 and stored in the first DB server device 2. Also, the encryption key used for encrypting the serial number NS of the first PJ3 is transmitted from the first AP server device 1 to the first PJ3 via the PC4.

[0069] Next, with reference to FIG. 3, a sequence in which the PC4 displays the first data D1 will be described. FIG. 3 is a diagram showing an example of a sequence in which the PC4 displays the first data D1. As shown in FIG. 3, first, in step S201, in response to an operation on the PC4 by the first user U1, the PC4 requests the first AP server device 1 for the login of the first user U1 and the transmission of the first data D1. At this time, the PC4 transmits a user ID and a password to the first AP server device 1.

[0070] Next, in step S203, the first AP server device 1 executes an authentication process for the first user U1. In the following description, the case where the authentication of the first user U1 by the first AP server device 1 is successful will be described. The first acquisition unit 112 of the first AP server device 1 executes the processes of the following steps S205, S209, S217, and S225 in order to transmit the first data D1 to the PC4 in response to a request from the PC4. Next, in step S205, the first acquisition unit 112 of the first AP server device 1 transmits the user ID of the first user U1 to the first DB server device 2 and requests specific correspondence information DP corresponding to the user ID. Next, in step S207, the first DB server device 2 transmits the specific correspondence information DP to the first AP server device 1.

[0071] Next, in step S209, the first acquisition unit 112 of the first AP server device 1 transmits the specific correspondence information DP to the second AP server device 5 and requests the serial number NS of the first PJ3. The serial number NS of the first PJ3 is stored in the projector list PL of the second DB server device 6. The projector list PL is stored in the second DB server device 6. The projector list PL is a list that associates the serial number NS of a projector owned by a corporation such as a stock company or an individual corresponding to the specific correspondence information DP with the specific correspondence information DP. In the following description, the projector list PL may be described as the "PJ list PL" for convenience.

[0072] Next, in step S211, in response to the request from the first AP server device 1, the second AP server device 5 transmits the specific correspondence information DP to the second DB server device 6 and requests the serial number NS of the first PJ3. Next, in step S213, in response to the request from the second AP server device 5, the second DB server device 6 transmits the serial number NS of the first PJ3 to the second AP server device 5. Next, in step S215, in response to the request from the first AP server device 1, the second AP server device 5 transmits the serial number NS of the first PJ3 to the first AP server device 1.

[0073] Next, in step S217, the first acquisition unit 112 of the first AP server device 1 transmits the serial number NS of the first PJ3 to the second AP server device 5 and requests the first data D1 of the first PJ3. Next, in step S219, in response to a request from the first AP server device 1, the second AP server device 5 transmits the serial number NS of the first PJ3 to the second DB server device 6 and requests the first data D1 of the first PJ3. Next, in step S221, in response to a request from the second AP server device 5, the second DB server device 6 transmits the first data D1 of the first PJ3 to the second AP server device 5.

[0074] Next, in step S223, in response to a request from the first AP server device 1, the second AP server device 5 transmits the first data D1 of the first PJ3 to the first AP server device 1. Next, in step S225, the first acquisition unit 112 of the first AP server device 1 transmits the first data D1 of the first PJ3 to the PC4 and causes the first data D1 to be displayed on the display of the PC4. Then, the process ends.

[0075] In this way, the first user U1 can obtain the first data D1 of the first PJ3 from the second DB server device 6 arranged in the second area AR2 by operating the PC4. Note that if the serial number NS of the first PJ3 is defined as personal information by the law regarding the protection of personal information in the first area AR1, the serial number NS of the first PJ3 in FIG. 3 may be replaced with an "encrypted serial number" as necessary as described with reference to FIG. 2.

[0076] Next, with reference to FIG. 4, a sequence in which the PC4 obtains the second data D2 will be described. FIG. 4 is a diagram showing an example of a sequence in which the PC4 obtains the second data D2. Note that in FIG. 4, a case where the PC4 has logged in to the first AP server device 1 in advance will be described. First, in step S301, the first PJ3 is communicably connected to the second AP server device 5, for example, in accordance with the WebSocket standard. Next, in step S303, the PC 4 transmits the serial number NS of the first PJ3 to the first AP server device 1, and requests the first AP server device 1 to transmit the second data D2 of the first PJ3 to the first transmission destination R1. The first transmission destination R1 is, for example, the PC 4.

[0077] Next, in step S305, the first AP server device 1 transmits the serial number NS of the first PJ3 to the second AP server device 5, and requests the second AP server device 5 to transmit the first transmission destination information indicating the first transmission destination R1 to the first PJ3. Next, in step S307, the second AP server device 5 transmits the first transmission destination information indicating the first transmission destination R1 to the first PJ3 in response to the request from the first AP server device 1. Next, in step S309, the second transmission unit 312 of the first PJ3 transmits the second data D2 of the first PJ3 to the first AP server device 1, and requests the first AP server device 1 to transmit the second data D2 of the first PJ3 to the first transmission destination R1.

[0078] Next, in step S311, the first AP server device 1 causes the first DB server device 2 to store the second data D2 of the first PJ3 in association with the specific correspondence information DP. Next, in step S313, the first AP server device 1 transmits the second data D2 of the first PJ3 to the PC 4 which is the first transmission destination R1, and causes the second data D2 of the first PJ3 to be displayed on the display possessed by the PC 4. Then, the process ends.

[0079] In this way, the first user U1 can acquire the second data D2 of the first PJ3 by operating the PC 4. Note that in FIG. 4, the case where the first AP server device 1 causes the first DB server device 2 to store the second data D2 of the first PJ3 in association with the specific correspondence information DP has been described, but the embodiment is not limited to this. The first AP server device 1 may acquire the second data D2 of the first PJ3 from the first DB server device 2.

[0080] Next, with reference to FIG. 5, the information output by the electronic device will be described. FIG. 5 is a chart showing an example of the information output by the electronic device. In the present embodiment, the case where the "electronic device" is a projector has been described, but the embodiment is not limited thereto. The "electronic device" may be, for example, a printer. Also, the "electronic device" may be, for example, a smartwatch. Note that the "electronic device" includes the "first electronic device" and the "second electronic device".

[0081] As shown in FIG. 5, the information output by the electronic device is composed of data DD that is not personal information, data DJ that is personal information, and data DM that may be personal information. Data DD is included in the first data D1. Data DJ is included in the second data D2. Data DM may be included in the first data D1 or may be included in the second data D2.

[0082] When the "electronic device" is a projector, data DD includes the usage time of the light source, the temperature of the intake air, the resolution of the input source, and the error history. Also, data DJ includes the email address of the projector. Also, data DM includes the projected video and the captured image of the camera. When the captured image of the camera includes, for example, an image of the first user U1, the captured image of the camera is included in the second data D2.

[0083] Also, when the "electronic device" is a printer, data DD includes the number of printed sheets, the remaining amount of ink, and the error history. Also, data DJ includes the email address of the printer. Also, data DM includes the print data. When the print data includes personal information such as the name of the first user U1, the print data is included in the second data D2.

[0084] Also, when the "electronic device" is a smartwatch, data DD includes communication volume, CPU load, and memory usage. Also, data DJ includes the position data of the smartwatch and the activity amount data of the user. Note that the activity amount data of the user includes the step count data of the user and the heart rate data of the user. Also, data DM includes photo data and audio data. When the photo data includes, for example, an image of the first user U1, the photo data is included in the second data D2.

[0085] [This Embodiment and Operational Effects] As described above with reference to FIGS. 1 to 5, the data management method according to this embodiment includes: the first application server device 1 arranged in the first area AR1 stores in the first database server device 2 arranged in the first area AR1 the personal information of the first user U1 living in the first area AR1 and the specific correspondence information DP associated with the first projector 3 owned by the first user U1 in an associated manner; the first projector 3 stores the specific correspondence information DP; the first projector 3 transmits to the second database server device 6 arranged in the second area AR2 different from the first area AR1 the first data D1 which is data that does not include the personal information of the first user U1 among the information output by the first projector 3 and that indicates the state of the first projector 3, and the specific correspondence information DP; the second database server device 6 stores the first data D1 and the specific correspondence information DP in an associated manner; and the first application server device 1 obtains the first data D1 from the second database server device 6 using the specific correspondence information DP.

[0086] That is, the second database server device 6 arranged in the second area AR2 stores the first data D1 and the specific correspondence information DP in association with each other, and the first application server device 1 arranged in the first area AR1 uses the specific correspondence information DP to obtain the first data D1 from the second database server device 6. Here, the first data D1 is data that does not include the personal information of the first user U1 among the information output by the first projector 3 and that indicates the state of the first projector 3. Therefore, among the information output by the first projector 3, the first application server device 1 arranged in the first area AR1 can obtain the first data D1 from the second database server device 6 arranged in the second area AR2. Therefore, among the information output by the first projector 3, the first data D1 can cross borders. In other words, when the first projector 3 transmits the first data D1 to the second database server device 6, the first data D1 can cross borders from the first area AR1 to the second area AR2. Also, when the first application server device 1 obtains the first data D1 from the second database server device 6, the first data D1 can cross borders from the second area AR2 to the first area AR1.

[0087] Also, in the above data management method, the first projector 3 is arranged in the first area AR1, and the first application server device 1 obtains, from the first projector 3, second data D2 that is data other than the first data D1 among the information output by the first projector 3 and that includes the personal information of the first user U1. Therefore, the first projector 3 is arranged in the first area AR1, and the first application server device 1 acquires the second data D2 from the first projector 3. Here, the second data D2 is data that includes personal information of the first user U1 excluding the first data D1 among the information output by the first projector 3. Therefore, since the first application server device 1 acquires the second data D2 from the first projector 3 arranged in the first area AR1, cross-border transfer of data including personal information can be suppressed. In other words, cross-border transfer of the second data D2 including personal information of the first user U1 residing in the first area AR1 can be suppressed.

[0088] Also, in the above data management method, the first application server device 1 transmits the second data D2 to the first database server device 2 in association with specific correspondence information DP, and the first application server device 1 causes the first database server device 2 to store the second data D2 in association with the specific correspondence information DP. Therefore, the first application server device 1 arranged in the first area AR1 causes the first database server device 2 arranged in the first area AR1 to store the second data D2 of the first projector 3 arranged in the area AR1 in association with the specific correspondence information DP. Therefore, since the second data D2 is stored in the first database server device 2 arranged in the first area AR1, cross-border transfer of data including personal information can be suppressed. In other words, cross-border transfer of the second data D2 including personal information of the first user U1 residing in the first area AR1 can be suppressed.

[0089] Also, in the above data management method, the first application server device 1 stores, in the first database server device 2, first destination information indicating a first destination R1 included in the first area AR1, which is the transmission destination to which the first projector 3 transmits the second data D2, and the first projector 3 transmits the second data D2 to the first destination R1 based on the first destination information acquired from the first database server device 2. Therefore, the first projector 3 transmits the second data D2 to the first destination R1 included in the first area AR1 based on the first destination information acquired from the first database server device 2. Therefore, within the first area AR1, the first projector 3 can easily transmit the second data D2 to the first destination R1.

[0090] In the data management method described above, the second application server device 5 disposed in the second area AR2 notifies the first projector 3 of second destination information indicating a second destination R2 included in the first area AR1, and the first projector 3 transmits the personal information of the first user U1 to the second destination R2 based on the second destination information. Therefore, the first projector 3 transmits the personal information of the first user U1 to the second destination R2 included in the first area AR1 based on the second destination information notified from the second application server device 5. Therefore, within the first area AR1, the first projector 3 can easily transmit the personal information of the first user U1 to the second destination R2.

[0091] In the data management method described above, the specific correspondence information DP is identification information associated with both the first projector 3 and at least a second projector 7 different from the first projector 3. A second user U2 different from the first user U1 holds the second projector 7. The second projector 7 stores the specific correspondence information DP. The second projector 7 transmits to the second database server device 6 data that does not include the personal information of the second user U2 among the information output by the second projector 7 and that indicates the state of the second projector 7, and the specific correspondence information DP. The second database server device 6 stores the third data D3 and the specific correspondence information DP in association with each other. That is, the second database server device 6 stores the third data D3 and the specific correspondence information DP in association with each other. Here, the third data D3 is data that does not include the personal information of the second user U2 among the information output by the second projector 7 and that indicates the state of the second projector 7. Also, the specific correspondence information DP is identification information associated with both the first projector 3 and at least a second projector 7 different from the first projector 3. Therefore, the second database server device 6 can store the first data D1 of the first projector 3 and the third data D3 of the second projector 7 in association with one specific correspondence information DP. Thus, when a corporation such as a stock company or an individual owns a plurality of projectors including the first projector 3 and the second projector 7, the owner information can be easily managed by using the specific correspondence information DP.

[0092] Also, in the above data management method, when the authentication of the first user U1 from the personal computer 4 owned by the first user U1 disposed in the first area AR1 is successful by the first application server device 1, the first application server device 1 transmits the first data D1 and the personal information of the first user U1 to the personal computer 4. Therefore, the first application server device 1 transmits the first data D1 and the personal information of the first user U1 to the personal computer 4 owned by the first user U1 disposed in the first area AR1. Thus, within the first area AR1, the personal computer 4 owned by the first user U1 can easily acquire the first data D1 and the personal information of the first user U1.

[0093] Also, in the above data management method, the second data D2 includes at least a part of the setting information of the first projector 3. Therefore, since the second data D2 includes at least a part of the setting information of the first projector 3, the second data D2 can be set in accordance with the law regarding the protection of personal information in the first area AR1. Therefore, the second data D2 can be set appropriately.

[0094] Also, in the above data management method, the second data D2 includes at least a part of the image information of the first projector 3. Therefore, since the second data D2 includes at least a part of the image information of the first projector 3, the second data D2 can be set in accordance with the law regarding the protection of personal information in the first area AR1. Therefore, the second data D2 can be set appropriately.

[0095] The data management system 100 according to the present embodiment includes a first database server device 2 that is arranged in the first area AR1 and stores personal information of a first user U1 living in the first area AR1 in association with specific correspondence information DP associated with the first projector 3 owned by the first user U1, a second database server device 6 that is arranged in a second area AR2 different from the first area AR1 and stores, in association with the specific correspondence information DP, first data D1 that is data output by the first projector 3 and does not include personal information of the first user U1 and indicates the state of the first projector 3, and a first application server device 1 that acquires the first data D1 from the second database server device 6 using the specific correspondence information DP. Therefore, the data management system 100 according to the present embodiment can achieve the same effects as the data management method according to the present embodiment.

Specifically, portable or fixed recording media such as flexible disks, HDDs, CD-ROMs (Compact Disk Read Only Memory), DVDs, Blu-ray (registered trademark) Discs, magneto-optical disks, flash memories, card-type recording media, etc. can be mentioned. Also, the recording medium may be a non-volatile memory device such as RAM, ROM, HDD, etc., which are internal storage devices provided in each of the first application server device 1, the first database server device 2, the first projector 3, the personal computer 4, the second application server device 5, the second database server device 6, and the second projector 7.

[0107] [Appendix] Hereinafter, a summary of the present disclosure is appended. (Appendix 1) A first application server device arranged in a first area causes a first file server device arranged in the first area to store in association the personal information of a first user residing in the first area, the association data associated with a first electronic device owned by the first user, and causes the first electronic device to store the association data. The first electronic device transmits to a second file server device arranged in a second area different from the first area, first data that does not include the personal information of the first user among the information output by the first electronic device and that indicates the state of the first electronic device, and the association data. The second file server device stores the first data and the association data in association with each other. The first application server device acquires the first data from the second file server device using the association data. A data management method including these steps.

[0108] As a result, the second file server device arranged in the second area stores the first data and the association data in association with each other, and the first application server device arranged in the first area acquires the first data from the second file server device using the association data. Here, the first data is data that does not include the personal information of the first user among the information output by the first electronic device and that indicates the state of the first electronic device. Therefore, among the information output by the first electronic device, the first application server device arranged in the first area can acquire the first data from the second file server device arranged in the second area. Therefore, among the information output by the first electronic device, the first data can cross borders. In other words, when the first electronic device transmits the first data to the second file server device, the first data can cross borders from the first area to the second area. Also, when the first application server device acquires the first data from the second file server device, the first data can cross borders from the second area to the first area.

[0109] (Appendix 2) The first electronic device is arranged in the first area, and the first application server device obtains, from the first electronic device, second data that is data other than the first data and includes personal information of the first user among the information output by the first electronic device. The data management method according to Appendix 1 includes this.

[0110] As a result, the first electronic device is arranged in the first area, and the first application server device obtains the second data from the first electronic device.
