Description

TECHNICAL FIELD

[0001] The present application relates to a method for calling up hygiene device data by a terminal device, wherein the hygiene device data are stored in an anonymized manner on a network device, wherein the hygiene device data comprise information about a hygiene device.

[0002] The present application also relates to a terminal device comprising communication means for communicating with a network device and / or a hygiene device and a processor and a memory with computer-readable instructions.

[0003] The present application also relates to a hygiene device comprising communication means for communicating with a network device and / or a terminal device and a processor and a memory with computer-readable instructions.

[0004] The present application also relates to a network device comprising communication means for communicating with a hygiene device and / or a terminal device and a processor and a memory with computer-readable instructions.

[0005] The present application also relates to a system consisting of a terminal device, a hygiene device and a network device. BACKGROUND

[0006] Although the present application can be applied universally to any hygiene device, terminal device and network device, the present application will be explained with regard to a kitchen sink, a mobile terminal device and a cloud.

[0007] Modern hygiene devices, such as kitchen sinks or similar devices, can generate hygiene device data, which can provide information about the use of the hygiene device. For example, the hygiene device data can reflect the amount of hot water used, the amount of cold water used or the energy consumption. Here, for simple calling up, the hygiene device data can be stored in the cloud and, if necessary, also used for anonymous evaluation by the manufacturer.

[0008] It is known for this to establish a user account for a user and to access the hygiene device data in the cloud using the user account. However, this method has the disadvantage that the hygiene device data cannot be stored in the cloud in an anonymized manner, since the hygiene device data must always be associated with an account. As a result, in the event of unauthorized access to the cloud, sensitive hygiene device data can reach third parties.

[0009] It is also known to store the hygiene device data in the cloud in an anonymized manner. It proves to be disadvantageous here that it cannot be seen who has access to the hygiene device data, since the owner of the hygiene device is unknown. As a result, an unauthorized third party can be output as the owner of the hygiene device in order to obtain access to the hygiene device data. SUMMARY

[0010] It is therefore an object of the present application to give a method for calling hygiene device data by a terminal device, wherein hygiene device data are stored in an anonymous manner on a network device, wherein the hygiene device data comprise information about a hygiene device.

[0011] It is a further object of the present application to give a corresponding terminal device, a hygiene device, a network device and a system consisting of a terminal device, a hygiene device and a network device.

[0012] It is a further object of the present application to give an alternative method for calling hygiene device data, an alternative terminal device, an alternative hygiene device, an alternative network device and an alternative system, the alternative system comprising a terminal device, a hygiene device and a network device.

[0013] In one embodiment, the present application achieves the aforementioned objects by means of a method for calling hygiene device data by a terminal device, in particular a mobile terminal device, wherein hygiene device data are stored in an anonymous manner on a network device, in particular in a cloud, wherein the hygiene device data comprise information about a hygiene device, the method comprising the following steps:

[0014] submitting a first data request by the terminal device;

[0015] submitting a second data request by the hygiene device after receiving a notification about the first data request which was intentionally submitted at least once by the terminal device;

[0016] comparing the first and second data requests by the network device;

[0017] providing hygiene device data by the network device to the terminal device based on the comparison of the first and second data requests;

[0018] calling hygiene device data by the terminal device.

[0019] In one embodiment, the present application achieves the aforementioned objects by means of a terminal device, in particular a mobile terminal device, the terminal device comprising communication means for communicating with a network device, in particular a cloud, and / or a hygiene device, and a processor and a memory having computer-readable instructions which, when executed by the processor, cause the terminal device to:

[0020] sending a command to the hygiene device, the command comprising terminal device identification information,

[0021] submitting a first data request to the network device, wherein the first data request is based on the terminal device identification information, and

[0022] receiving hygiene device data from the network device.

[0023] In one embodiment, the application achieves the above-mentioned object by means of a hygiene device comprising communication means for communicating with a network device, in particular a cloud, and / or with a terminal device, in particular a mobile terminal device, and a processor and a memory having computer-readable instructions which, when executed by the processor, cause the hygiene device to:

[0024] receive a command from the terminal device, the command comprising terminal device identification information, and

[0025] make a second data request to the network device, wherein the data request is based on the terminal device identification information and the hygiene device identification information.

[0026] In one embodiment, the application achieves the above-mentioned object by means of a network device, in particular a cloud, comprising communication means for communicating with a hygiene device and / or with a terminal device, in particular a mobile terminal device, and a processor and a memory having computer-readable instructions which, when executed by the processor, cause the network device to:

[0027] receive a first data request from the terminal device, wherein the first data request is based on terminal device identification information,

[0028] receive a second data request from the hygiene device, wherein the second data request is based on the terminal device identification information and the hygiene device identification information,

[0029] compare the first and second data requests, and

[0030] based on the comparison of the first and second data requests, send hygiene device data to the terminal device.

[0031] In one embodiment, the application achieves the above-mentioned object by means of a system consisting of a terminal device according to claim 14, a hygiene device according to claim 15 and a network device according to claim 16.

[0032] One of the advantages achieved thereby is that third parties can be prevented from unauthorized access to hygiene device data in a reliable and simple manner. Another advantage is that the calling of hygiene device data is prevented without being in direct proximity to the hygiene device, thus preventing the calling of hygiene device data by external users.

[0033] In one embodiment of the method, the data call can be initiated by the terminal device. To this end, the terminal device can send a data request to the network device. The hygiene device can receive a notification that the terminal device has or will send a data request and the hygiene device itself sends a second data request. The notification can in particular be sent by the terminal device. The network device can receive both data requests and can determine from a comparison of the two data requests that the terminal device can receive hygiene device data. Subsequently, the hygiene device can provide the hygiene device data to the terminal device so that the terminal device can call the hygiene device data.

[0034] Further features, advantages and other embodiments of the present application will be described or will become apparent in the course of the following description.

[0035] According to an advantageous refinement of the present application, the first data request comprises terminal device identification information. The terminal device identification information can for example be an ID of the terminal device. By means of the terminal device identification information the terminal device can be uniquely identified. The advantage is that a terminal device which has been authenticated for obtaining hygiene device data can be identified in a simple manner. Thereby, the hygiene device data can be provided directly to the terminal device without the need to re-authenticate the terminal device.

[0036] According to another advantageous refinement of the present application, the terminal device identification information is generated based on a hash value, a system time and a first random value. For example, the terminal device identification information can be a hash value of the system time and the random value. The advantage is that it is prevented that multiple terminal devices obtain the same terminal device identification information. Another advantage is that it is made difficult for an unauthorized third party to randomly determine the terminal device identification information.

[0037] According to another advantageous refinement of the present application, the second data request comprises hygiene device identification information. One of the advantages is that the hygiene device can be uniquely identified based on the hygiene device identification information.

[0038] According to another advantageous refinement of the present application, the hygiene device identification information is generated based on a hash value, a serial number of the hygiene device and a second random value. One of the advantages is that it is prevented that multiple hygiene devices obtain the same hygiene device identification information because the serial number is unique. Another advantage is that it is made difficult for an unauthorized third party to randomly determine the terminal device identification information.

[0039] According to another advantageous refinement of the present application, the second data request is generated based on the terminal device identification information. If the hygiene device knows the terminal device identification information, the second data request can be generated based on the terminal device identification information. Thus, the hygiene device is already able to connect with the desired terminal device. The advantage is that it is prevented that hygiene device data is provided to an undesired user because the second data request does not refer to a terminal device of the undesired user.

[0040] According to a further advantageous development of the application, the comparison of the first and second data request comprises a check whether the terminal device identification information corresponds to the hygiene device identification information. The hygiene device identification information can for example comprise the terminal device identification information. Thus, the network device can check whether the terminal device identification information comprised in the hygiene device identification information actually corresponds to the terminal device identification information from the first data request. Only when the terminal device identification information and the hygiene device identification information correspond to each other, the hygiene device data is provided to the terminal device. In this way it can be ensured that only the terminal device of the intended user obtains the hygiene device data and not the terminal device of an unauthorized user.

[0041] According to a further advantageous development of the application, the comparison of the first and second data request comprises a comparison of the time points at which the first and second data request were made and whether the difference between the two time points is smaller than a threshold value. In particular, it can be checked whether the two data requests were made within a defined time interval. For example, it can be checked whether the data requests occurred within a time period of less than 5 minutes, less than 3 minutes, less than 1 minute or less than 10 seconds. The advantage is that the likelihood of an unauthorized user obtaining access to the hygiene device data is reduced.

[0042] According to a further advantageous development of the application, the second data request is made only when the user operates an operating element on the hygiene device. For example, the user can send the first data request by means of the terminal device and subsequently operate an operating element on the hygiene device so that the hygiene device sends the second data request. The advantage is that it can be ensured that the data call is made by an authorized user.

[0043] According to a further advantageous development of the application, the second data request is made only when the terminal device sends a command to the hygiene device by means of a wireless communication means, in particular by means of Bluetooth. For example, the terminal device can connect with the hygiene device by means of Bluetooth and send a notification to the hygiene device by means of the Bluetooth connection. The notification can comprise a command for making the second data request and / or the terminal device identification information. Thus, the terminal device has to be physically located in the vicinity of the hygiene device in order to trigger the data request. The advantage is that it can be prevented that an unauthorized user obtains access to the hygiene device data without being physically close to the hygiene device.

[0044] According to a further advantageous development of the application, the wireless communication device requires connection information for communicating with the hygiene device, wherein the connection information is physically provided on the hygiene device. For example, the connection information can be a password printed on the hygiene device. The terminal device can only communicate with the hygiene device if the user provides the connection information to the terminal device. Thus, the user has to be physically located in the vicinity of the hygiene device in order to obtain the connection information. The advantage is that an unauthorized user can be prevented from obtaining access to the hygiene device data without being physically close to the hygiene device.

[0045] According to a further advantageous development of the application, the second data request is only made by the hygiene device upon receipt of the command if the signal strength of the command of the wireless communication device is greater than a threshold value. In other words, the second data request is only made by the hygiene device if the signal strength of the communication between the hygiene device and the terminal device is sufficiently high. In this way, the second data request can only be made if the terminal device is physically close to the hygiene device. The advantage is that an unauthorized user can be prevented from obtaining access to the hygiene device data in a larger surrounding of the hygiene device.

[0046] According to a further advantageous development of the application, the network device stores hygiene device identification information and / or terminal device identification information. Once the hygiene device data is provided to the terminal device, the terminal device can be classified as an authorized terminal device. Thus, the hygiene device data can be directly provided to the terminal device in the case of a later data request. To this end, the hygiene device identification information and / or the terminal device identification information can be stored on the network device so that the terminal device can be identified. The advantage is that the subsequent data request is simplified by the terminal device.

[0047] Further important features and advantages of the present application result from the dependent claims, the drawings and the description of the drawings by means of the drawings.

[0048] Of course, the features described above and explained below can be used not only in the indicated combinations, but also in other combinations or alone, without leaving the scope of the present application. BRIEF DESCRIPTION OF DRAWINGS

[0049] Preferred designs and embodiments of the application are shown in the drawings and explained in more detail in the following description, in which the same reference signs denote identical or similar or functionally identical components or elements.

[0052] Figure 2A terminal device according to an embodiment of the application is shown;

[0053] Figure 3 A hygiene device according to an embodiment of the application is shown;

[0054] Figure 4 A network device according to an embodiment of the application is shown; and

[0055] Figure 5 A system according to an embodiment of the application is shown. DETAILED DESCRIPTION

[0056] Figure 1 Steps of a method according to an embodiment of the application are shown in schematic form.

[0057] Figure 1 Steps of a method for calling hygiene device data by a terminal device are shown. The terminal device can in particular be a mobile terminal device, such as a smartphone, a tablet or a laptop. The hygiene device data comprises information about the hygiene device, such as the amount of water used, the average temperature of the water, the energy consumption, the maintenance period and / or the filling amount of a CO2 cartridge. The hygiene device data is stored on a network device, wherein the network device can for example be a local server or a cloud. In particular, the hygiene device data is stored on the network device in an anonymous manner, so that unauthorized third parties cannot associate the hygiene device data with a specific hygiene device.

[0058] In step S1, a first data request is made by the terminal device. The data request can for example comprise terminal device identification information, in particular an ID of the terminal device. The ID is formed from a hash value of a random number and a system time, in order to generate a unique, but not randomly determinable by unauthorized users, ID. The first data request is sent to the cloud. At this point, however, the cloud will not provide the hygiene device data, since the terminal device has not yet been authenticated.

[0059] In a second step S2, the second data request is made by the hygiene device after receiving a notification from the terminal device that the first data request has been made at least intentionally. The notification comprises the intention of the terminal device to make or to have made a data request. After the terminal device has made the first data request, the terminal device transmits its own ID to the hygiene device. After the notification, the hygiene device makes the second data request to the cloud. It is also conceivable that the terminal device first transmits its ID to the hygiene device together with the notification, the hygiene device makes the second data request and subsequently the terminal device makes the first data request. It is furthermore conceivable that the terminal device transmits its ID to the hygiene device together with the notification and subsequently the hygiene device and the terminal device make the data requests simultaneously. The second data request can for example comprise hygiene device identification information, which can comprise a hash value composed of a serial number of the hygiene device and a random number. The second data request can in particular comprise the ID of the terminal device.

[0060] It is conceivable that the hygiene device sends an acknowledgement to the terminal device when it obtains the notification of the intention to make the first data request. In particular, in this way the two devices can define the point in time at which they make the data requests.

[0061] The possibility that an unauthorized user can randomly guess the ID of the terminal device or the hygiene device identification information is reduced by the random number.

[0062] The notification to the hygiene device can for example be sent by the terminal device via Bluetooth. Thereby it is ensured that the terminal device has connected to the hygiene device before the data call and that the terminal device is physically located in the vicinity of the hygiene device.

[0063] In a third step S3, the first and second data requests are compared by the network device. For example, it is checked whether the second data request comprises the ID of the terminal device and whether the same ID of the terminal device is contained in the first data request. In particular, it is checked whether both the first and the second data request have been made within a certain time period. When the second data request corresponds to the first data request and both data requests have been made substantially simultaneously, the terminal device is authorized to receive the hygiene device data. It is conceivable that steps S1, S2 and S3 are repeated at least twice or at least three times in order to exclude with a higher probability that an unauthorized user obtains access to the hygiene device data.

[0064] In a fourth step S4, based on the comparison of the first data request with the second data request, the hygiene device data is provided to the terminal device by the cloud. When the terminal device is authorized by the comparison of the data requests receiving the hygiene device data, the hygiene device data is provided to the terminal device. The hygiene device data can be stored in the cloud in an anonymous manner and referenced only by the serial number of the hygiene device or the hygiene device identification information. Because the transmission in the case of the second data call can include the hygiene device identification information of the serial number, the corresponding hygiene device data can be provided.

[0065] In a fifth step S5, the hygiene device data is received from the terminal device. It can be considered that the ID of the terminal device and the hygiene device identification information are stored in the cloud. When the terminal device makes another data request, the ID of the terminal device can be compared with the stored ID of the terminal device. If the two IDs coincide, further hygiene device data can be provided directly to the terminal device.

[0066] Figure 2 A terminal device according to an embodiment of the application is shown in schematic form.

[0067] Here, the terminal device 1 in the form of a mobile terminal device 1 comprises communication means 2a for communicating with a network device (not shown), in particular a cloud and / or a hygiene device (not shown), and a processor 3a and a memory 4a with computer-readable instructions which, when executed by the processor 3a, cause the terminal device 1 to:

[0068] send a command to the hygiene device, wherein the command comprises terminal device identification information,

[0069] issue a first data request to the network device, wherein the first data request is based on the terminal device identification information and a random value, and

[0070] receive hygiene device data from the network device.

[0071] The terminal device 1 is in particular designed to carry out the steps S1 and S5 of Figure 1 It can be considered that the terminal device 1 sends a command to the network device for deleting the terminal device identification information and / or the hygiene device identification information.

[0072] In the memory 4a a program, in particular an App, can be stored which enables a graphical display of the hygiene device data and which enables the initiation of the data call.

[0073] Figure 3 A hygiene device according to an embodiment of the application is shown in schematic form.

[0074] Figure 3A hygiene device 5 is shown, which comprises communication means 2b for communicating with a network device (not shown), in particular a cloud, and / or with a terminal device (not shown), in particular a mobile terminal device, and a processor 3b and a memory 4b with computer readable instructions which, when executed by the processor 3b, cause the hygiene device 5 to:

[0075] receive a command from the terminal device, wherein the command comprises terminal device identification information; and

[0076] make a second data request to the network device, wherein the data request is based on the terminal device identification information and the hygiene device identification information.

[0077] The hygiene device 5 can in particular perform the step S2 according to Figure 1 The hygiene device 5 can make the second data request to the network device only if the command from the terminal device 1 specifies that the hygiene device 5 shall make the data request.

[0078] Connection information 8 is provided on the hygiene device 5, here in the form of a printed password. By means of the password 8, the user can connect the terminal device 1 with the hygiene device 5, so that the hygiene device 5 and the terminal device 1 can communicate with each other. In particular, it can be a Bluetooth connection. It can be considered that the command for sending the second data request can only be sent by means of this connection, in particular the Bluetooth connection. Thus, the possibility that an unauthorized user can issue the command for making the second data request is reduced, because the connection information 8 is only visible when the user is located in front of the hygiene device 5. Even if the connection information 8 is accessible to an unauthorized user, the unauthorized user cannot make the command for the second data request from a location remote from the hygiene device, because a connection by Bluetooth can only be made over a short distance.

[0079] The hygiene device 5 can be configured to issue the command for making the second data request only if the signal strength of the Bluetooth connection is greater than a limit value. Thus, only a user who is in close proximity to the hygiene device 5 can issue the command for making the second data request.

[0080] Figure 4 A network device according to one embodiment of the application is shown in schematic form.

[0081] Figure 4 A network device 6 is shown, here in the form of a cloud, comprising communication means 2c for communicating with a hygiene device (not shown) and / or with a terminal device (not shown), in particular a mobile terminal device, and a processor 3c and a memory 4c with computer readable instructions which, when executed by the processor, cause the network device 6 to:

[0082] receiving a first data request from the terminal device 1, wherein the first data request is based on the terminal device identification information,

[0083] receiving a second data request from the hygiene device 5, wherein the second data request is based on the terminal device identification information and the hygiene device identification information,

[0084] comparing the first and the second data request, and

[0085] sending hygiene device data to the terminal device 1 based on the comparison of the first and the second data request.

[0086] The network device 6 is in particular designed for carrying out steps S3 and S4 according to Figure 1 .

[0087] The network device 6 is capable of storing the hygiene device data in an anonymous manner and using only the serial number and / or the hygiene device identification information as a reference. Thus, the hygiene device data cannot be associated with a specific user. It is possible that the current hygiene device data of the hygiene device 5 are regularly queried by the network device 6 and / or provided by the hygiene device 5 and stored.

[0088] Figure 5 A system according to one embodiment of the application is shown in schematic form.

[0089] In Figure 5 , a system 7 is shown, comprising a terminal device 2, a hygiene device 5 and a network device 6. The terminal device 2 is in particular configured according to Figure 2 , the hygiene device 5 is in particular configured according to Figure 3 , and the network device 6 is in particular configured according to Figure 4 .

[0090] The system 7 is in particular designed for carrying out steps S1 to S5 according to Figure 1 .

[0091] The terminal device 1 can send a first data request 10 comprising the terminal device identification information to the network device 6. Furthermore, the terminal device 1 can send a notification 11, here in the form of a command 11, to the hygiene device 5, so that the hygiene device should send a second data request 12 to the network device 6. The command 11 can comprise the terminal device identification information. The hygiene device 5 can send the second data request 12 to the network device 6, wherein the second data request can comprise the terminal device identification information and the hygiene device identification information. Next, the network device 6 can compare the first data request 10 and the second data request 12 and, depending on the comparison, send hygiene device data 13 to the terminal device 1.

[0092] In summary, at least one embodiment of the present application can have at least one of the following features and / or provide at least one of the following advantages:

[0093] Providing hygiene equipment data only to authorized users.

[0094] Preventing access to hygiene equipment data by external users.
