[0050] It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0051] The present application provides a data processing method, which is applied to a data processing device. Figure 1 A flow chart of a data processing method provided in an embodiment of the present application is as follows: Figure 1 As shown, the data processing method may include:

[0052] S101. Upon receiving the successful binding information of the first identity information to the first house information, the residential smart contract corresponding to the first house information in the control blockchain system is made effective.

[0053] In an embodiment of the present application, upon receiving information on successful binding of the first identity information to the first house information, the data processing device controls the residential smart contract corresponding to the first house information in the blockchain system to take effect.

[0054] A data processing method provided in the present application can be applied in a scenario where access to home appliances in first house information is controlled using first identity information.

[0055] It should be noted that the data processing device can be a house rental platform. In this case, the first identity information can be the lessor, and the first house information can be the lessee; the specific data processing device can be determined according to actual conditions, and the embodiments of the present application are not limited here.

[0056] In the embodiment of the present application, the data processing device and the blockchain system are independent of each other, and the data processing device stores all data that need to be guaranteed to be secure in the blockchain system.

[0057] It should be noted that the residence smart contract is published in the blockchain system. The residence smart contract can be understood as the first identity information paying a certain room fee in exchange for the right to reside in the first house information for a period of time. After the first identity information pays successfully, it indicates that the first identity information is successfully bound to the first house information. At this time, the residence smart contract takes effect, and the first identity information has the right to reside in the first house information for a period of time; the residence smart contract can also be that the owner of the first house information directly transfers the right to reside in the first house information to the first identity information, and there is no need to pay the room fee, and the first identity information and the first house information are directly bound; the specific binding conditions can be determined according to actual conditions, and the embodiments of the present application are not limited here.

[0058] In the embodiment of the present application, before the first identity information is bound to the first house information, the first identity information needs to be registered on the data processing device.

[0059] Specifically, when the data processing device receives an identity registration request for the first identity information, it parses the identity registration request to obtain the first identity information, and generates a first identity public key, a first identity private key and a first identity fingerprint identifier corresponding to the first identity information; stores the first identity public key and the first identity fingerprint identifier in the blockchain system, and returns the first identity private key and the first identity fingerprint identifier to the first identity information.

[0060] It can be understood that by storing the first identity public key and the first identity fingerprint identifier in the blockchain system, the information is not easily tampered with, and the security of the identity information can be guaranteed.

[0061] It should be noted that when storing the first identity public key and the first identity fingerprint identifier in the blockchain system, consensus is required before they can be added to the blockchain system.

[0062] It should be noted that, when the first identity information receives the first identity private key and the first identity fingerprint identifier sent by the data processing device, it indicates that the first identity information is successfully registered on the data processing device.

[0063] In an embodiment of the present application, the first house information includes at least one household appliance. When a new household appliance is added to the first house information, the new household appliance needs to be added to the data processing device.

[0064] Specifically, when receiving a device adding request from a first home appliance, the data processing device parses the device adding request to obtain the first home appliance and the first house information corresponding to the first home appliance; generates a first device public key, a first device private key and a first device fingerprint identifier according to the first home appliance; stores the first device public key, the first device fingerprint identifier, the first home appliance and the first house information correspondingly in the blockchain system, and returns the first device private key and the first device fingerprint identifier to the first home appliance.

[0065] For example, assuming that a smart air conditioner (first home appliance) is added to Room A (first house information), it is necessary to add the smart air conditioner to the data processing device. At this time, a device addition request to add the smart air conditioner to Room A is sent to the data processing device. After the data processing device parses the device addition request, it obtains the smart air conditioner and Room A to which the smart air conditioner is added, and then generates the device public and private keys and device fingerprint identifier corresponding to the smart air conditioner, and then returns the device private key and device fingerprint identifier to the smart air conditioner. At this time, when the smart air conditioner receives the device private key and device fingerprint identifier, it stores the device private key and device fingerprint identifier in its own trusted platform module. Since the trusted platform module is an encryption module, it can prevent the device's own information from being tampered with.

[0066] It can be understood that by storing the first device public key and the first device fingerprint identifier in the blockchain system, the information is not easily tampered with, and the security of the device information can be guaranteed.

[0067] It should be noted that when the first device public key and the first device fingerprint identifier are stored in the blockchain system, they need to be added to the blockchain system after consensus.

[0068] It should be noted that, when the first home device receives the first device private key and the first device fingerprint identifier sent by the data processing device, it indicates that the first home device is successfully added to the data processing device.

[0069] S102. After the residence smart contract takes effect, the access control authority of the first identity information to the first house information is determined according to the binding success information.

[0070] In an embodiment of the present application, after the residence smart contract takes effect, the data processing device determines the access control authority of the first identity information to the first house information based on the binding success information.

[0071] It should be noted that the effectiveness of the residence smart contract indicates that the first identity information already has the residence right corresponding to the first house information. At this time, the access control authority of the first house information needs to be opened to the first identity information so that the first identity information can access and control the home appliances in the first house information.

[0072] It should be noted that different first identity information corresponds to different access control permissions, so the corresponding access control permissions can be determined through different binding success information; for example, assuming that user A is successfully bound to room B at this time, if user A is only bound to room B for one day, it means that user A only has the right to reside in room B for one day. At this time, user A may obtain access control permissions to a small number of home appliances in room B, for example, access control to the air conditioner, curtains and lights, but if he only lives there for one day, he cannot obtain access control to the password lock of room B; if user A is bound to room B for one year, it means that user A has the right to reside in room B for one year. At this time, user A may obtain access control permissions to most of the home appliances in room B, that is, he has access control to the password lock of room B and can change the password of room B; if user A is the owner of room B, it means that user A has the long-term right to reside in room B, that is, he obtains access control permissions to all home appliances in room B; the specific access control permissions are determined according to the actual situation, and the embodiments of the present application are not limited here.

[0073] It should be noted that access control permissions include viewing device information, access control operations on devices, etc. Specific access control permissions are formulated based on actual conditions and are not limited in this embodiment of the present application.

[0074] S103, activating the access control smart contract of the first house information in the blockchain system according to the access control authority; the access control smart contract is the home appliances in the first house information that are accessed by the access control authority.

[0075] In an embodiment of the present application, after the data processing device determines the access control authority of the first identity information to the first house information, it activates the access control smart contract of the first house information in the blockchain system according to the access control authority; the access control smart contract is the home equipment in the first house information that is accessed corresponding to the access control authority.

[0076] It should be noted that the access control smart contract is a contract corresponding to the first house information pre-stored in the blockchain system. The access control smart contract configures different access control permissions for home appliances in the first house information for different identity information. The first identity information needs to implement access control operations on home appliances based on this access control smart contract.

[0077] S104: upon receiving an access control request for a target home device using the first identity information, implement an access control operation for the target home device using the first identity information according to an access control smart contract.

[0078] In an embodiment of the present application, after activating the access control smart contract of the first house information, the data processing device, upon receiving an access control request for the target home device of the first identity information, implements the access control operation of the first identity information on the target home device according to the access control smart contract.

[0079] It should be noted that, since different identity information has different access control permissions for home appliances in the first house information, it is necessary to use an access control smart contract to determine whether the first identity information has the permission corresponding to this access control operation.

[0080] It should be noted that the access control request can be an access control operation of the first identity information directly on the home device, or it can be an access control operation of the first identity information on one home device to another home device; the specific access control request is determined based on the actual situation, and the embodiment of the present application is not limited here.

[0081] In an optional embodiment of the present application, a method for directly controlling access to a home device using first identity information is provided. Figure 2 An exemplary access control operation method process provided in the embodiment of the present application Figure 1 ,like Figure 2 As shown, the method is as follows:

[0082] S201. Parse the access control request to obtain first signature information of the first identity information and a first access control operation corresponding to the target home device.

[0083] In an embodiment of the present application, when a data processing device receives an access control request for a target home device from first identity information, it parses the access control request to obtain first signature information of the first identity information and a first access control operation corresponding to the target home device.

[0084] It should be noted that, in this embodiment, the request type of the access control request is access to the target home device.

[0085] In the embodiment of the present application, the first signature information is information generated after the first identity information uses the first identity private key to sign the first access control operation and the first identity fingerprint identifier stored in the first identity information.

[0086] It should be noted that when the first identity information requests a first access control operation on the target home device, it is necessary to use the first identity private key to sign the first access control operation and the first identity fingerprint identifier stored in the first identity information. After obtaining the first signature information, the first signature information and the first access control operation are sent together to the data processing device.

[0087] It should be noted that since the data processing device is not sure about the security of the access control request when it receives it, the first identity information is required to use the first identity private key to sign the first access control operation and the first identity fingerprint identifier stored in the first identity information, and then use the first identity public key stored in the blockchain system to verify the first signature information to further ensure security.

[0088] S202. Searching for a first identity public key corresponding to the first identity information in the blockchain system; and verifying the first signature information using the first identity public key and the first identity fingerprint identifier stored in the blockchain system.

[0089] In an embodiment of the present application, after obtaining the first signature information and the first access control operation, the data processing device searches for the first identity public key corresponding to the first identity information from the blockchain system; and uses the first identity public key and the first identity fingerprint identifier stored in the blockchain system to verify the first signature information.

[0090] It should be noted that since the first identity fingerprint identifier corresponding to the first identity information is also stored in the first identity information, the first identity fingerprint identifier in the first identity information may be modified and the security cannot be guaranteed to the maximum extent. Therefore, after receiving the first signature information, the data processing device not only needs to use the first identity public key stored in the blockchain system to verify the first identity private key corresponding to the first signature information, but also needs to use the first identity fingerprint identifier stored in the blockchain system to verify the first identity fingerprint identifier in the first signature information, which can further ensure security.

[0091] S203. When the signature verification is successful, obtain the access control smart contract corresponding to the first identity information from the blockchain system.

[0092] In an embodiment of the present application, when the signature verification is successful, the data processing device obtains the access control smart contract corresponding to the first identity information from the blockchain system.

[0093] It should be noted that, if the signature verification fails, the access control request is discarded and the next access control request is processed.

[0094] S204: Implement a first access control operation on the target home device using the first identity information according to the access control smart contract.

[0095] In an embodiment of the present application, after acquiring the access control smart contract, the data processing device implements a first access control operation on the target home device based on the first identity information according to the access control smart contract.

[0096] Specifically, the target home device and the target access control authority corresponding to the target home device are searched from the access control smart contract; if the target access control authority includes the first access control operation, the target home device is controlled to complete the first access control operation; if the target access control authority does not include the first access control operation, the target home device is controlled not to respond to the first access control operation.

[0097] For example, assuming that the first access control operation is to open the curtains, if in the access control smart contract, the target access control permission of the first identity information for the curtains is to allow the curtains to be opened or closed, and the target access control permission includes the first access control operation, the curtains are controlled to be opened; the specific access control permissions and access control requests are determined based on actual conditions, and the embodiments of the present application are not limited here.

[0098] In another optional embodiment of the present application, a method for controlling access of a home device to another home device using the first identity information is provided. Figure 3 An exemplary access control operation method process provided in the embodiment of the present application Figure 2 ,like Figure 3 As shown, the method is as follows:

[0099] S301, parsing the access control request to obtain the second signature information of the first identity information, the third signature information of the first home device, and the second access control operation corresponding to the target home device.

[0100] In an embodiment of the present application, when the data processing device receives an access control request for a target home device from the first identity information, it parses the access control request to obtain the second signature information of the first identity information, the third signature information of the first home device, and the second access control operation corresponding to the target home device.

[0101] It should be noted that, in this embodiment, the request type of the access control request is to control the first home device to access the target home device.

[0102] In an embodiment of the present application, the second signature information is information generated after the first identity information uses the first identity private key to sign the second access control operation and the first identity fingerprint identifier stored in the first identity information; the third signature information is information generated after the first home device uses the first device private key to sign the second access control operation and the first device fingerprint identifier stored in the first home device.

[0103] It should be noted that when the first identity information requests the use of the first home device to perform a second access control operation on the target home device, the first identity private key is required to sign the second access control operation and the first identity fingerprint identifier stored in the first identity information, and the first device private key is used to sign the second access control operation and the first device fingerprint identifier stored in the first home device. After obtaining the second signature information and the third signature information, the second signature information, the third signature information and the second access control operation are sent together to the data processing device.

[0104] It should be noted that, since the data processing device is not sure about the security of the access control request when it receives it, the first identity information is required to use the first identity private key to sign the second access control operation and the first identity fingerprint identifier stored in the first identity information, and the first home device is required to use the first device private key to sign the second access control operation and the first device fingerprint identifier stored in the first home device, and then use the first identity public key and the first device public key stored in the blockchain system to verify the second signature information and the third signature information twice to further ensure security.

[0105] S302. Search the blockchain system for the first identity public key corresponding to the first identity information; and use the first identity public key and the first identity fingerprint identifier stored in the blockchain system to verify the second signature information.

[0106] In an embodiment of the present application, after obtaining the second signature information, the third signature information and the second access control operation, the data processing device searches the blockchain system for the first identity public key corresponding to the first identity information; and uses the first identity public key and the first identity fingerprint identifier stored in the blockchain system to verify the second signature information.

[0107] It should be noted that since the first identity information and the first home device also store the first identity fingerprint identifier corresponding to the first identity information and the first device fingerprint identifier corresponding to the first home device, the first identity fingerprint identifier in the first identity information and the first device fingerprint identifier in the first home device may be modified, and the security cannot be guaranteed to the maximum extent. Therefore, after receiving the second signature information and the third signature information, the data processing device not only needs to use the first identity public key and the first device private key stored in the blockchain system to verify the first identity private key corresponding to the second signature information and the first device private key corresponding to the third signature information, but also needs to use the first identity fingerprint identifier and the first device fingerprint identifier stored in the blockchain system to verify the first identity fingerprint identifier in the second signature information and the first device fingerprint identifier in the third signature information, which can further ensure security.

[0108] S303: When the signature verification succeeds once, the first device public key corresponding to the first household device is searched in the blockchain system; and the third signature information is verified twice using the first device public key and the first device fingerprint identifier stored in the blockchain system.

[0109] In an embodiment of the present application, when the signature verification is successful once, the data processing device searches the blockchain system for the first device public key corresponding to the first home device; and uses the first device public key and the first device fingerprint identifier stored in the blockchain system to perform a second verification on the third signature information.

[0110] It should be noted that, if a signature verification fails, the access control request is discarded and the next access control request is processed.

[0111] S304: When the second signature verification is successful, obtain the access control smart contract corresponding to the first identity information from the blockchain system.

[0112] In an embodiment of the present application, when the secondary signature verification is successful, the data processing device obtains the access control smart contract corresponding to the first identity information from the blockchain system.

[0113] It should be noted that if the second signature verification fails, the access control request is discarded and the next access control request is processed.

[0114] S305: Implement a second access control operation on the target home device using the first home device using the first identity information according to the access control smart contract.

[0115] In an embodiment of the present application, after acquiring the access control smart contract, the data processing device implements a second access control operation on the target home device using the first home device using the first identity information according to the access control smart contract.

[0116] Specifically, the first home device and the first access control authority corresponding to the first home device are searched from the access control smart contract; if the first access control authority includes the authority for the first home device to control the target home device, the target home device and the target access control authority corresponding to the target home device are searched; if the first access control authority does not include the authority for the first home device to control the target home device, the first home device is controlled not to respond to the second access control operation; if the target access control authority includes the second access control operation, the first home device is used to control the target home device to complete the second access control operation; if the target access control authority does not include the second access control operation, the target home device is controlled not to respond to the second access control operation.

[0117] In the embodiment of the present application, after the first household appliance is found to be lost, the loss information of the first household appliance is sent to the data processing device so that the data processing device can locate the current position of the first household appliance.
