[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0026] In the subsequent description, the suffixes such as "module", "component" or "unit" used to represent elements are only used to facilitate the description of the present application and have no specific meaning. Therefore, "module" and "component" can be used interchangeably.

[0027] With the rapid development of smart homes, people are becoming more and more dependent on them, and data security issues may also be involved in the use process, which makes people pay more attention to the safety factor in the use process. Usually, password unlocking or direct face recognition and other technologies are used to enhance the security of the device, but this alone is not enough. Password unlocking cannot verify the true identity of the unlocker, and because the human face will have some growth and changes, face recognition may bring the risk of misidentification, that is to say, the safety factor of the device is still low.

[0028] In order to solve the problems mentioned in the background technology, according to one aspect of the embodiment of the present application, a device control system is provided, such as Figure 1 As shown, including:

[0029] The device end 102 is used to collect target data of the target object according to the verification strategy corresponding to the target device when it is detected that the verification interface of the target device is triggered; send the target data to the blockchain to generate an object key in the blockchain; authenticate the object key, and when the identity authentication is passed, encrypt the device data and the target data of the target device through the blockchain to generate a first key; forward the first key and the received control instruction to the cloud platform, so that the cloud platform controls the target device to perform the operation corresponding to the control instruction when the first key and the second key are successfully verified, wherein the second key is generated by the historical usage data of the target device and the cloud platform data of the cloud platform through the blockchain;

[0030] The cloud platform 104, upon receiving the control instruction sent by the device, encrypts the cloud platform data and the historical usage data of the target device using the blockchain to generate a second key, wherein the historical usage data is generated by the historical usage record of the target device; pairs the second key with the first key, and, if the pairing is successful, controls the target device to perform an operation corresponding to the control instruction;

[0031] The blockchain network 106 is connected to the device side and the cloud platform respectively, and is used to encrypt the target data sent by the device side to generate an object key; encrypt the device data and target data of the target device to generate a first key; encrypt the historical usage data and the cloud platform data to generate a second key.

[0032] This application is applied to device control, and in particular to smart authentication in smart homes.

[0033] The target device and the cloud platform are connected to the blockchain, and the data is encrypted through the blockchain. The encrypted keys of the two ends are mutually authenticated to ensure the information security of the device. By using blockchain technology to encrypt the user's biometrics and generate corresponding keys, the security issues caused by misidentification of fingerprints or facial information are reduced; the identity information of the device and the cloud platform are established through the blockchain. When the device receives the control command, it will authenticate the object of the command based on the blockchain, and the cloud platform will also authenticate the identity information of the controlled device, thereby preventing the smart home device from being invaded.

[0034] The present application provides a system that uses blockchain technology to encrypt the user's identity information and generate corresponding keys. Smart home devices perform different identity information verifications based on their security levels. Smart devices generate device keys based on their own information and user information. The cloud platform that controls the device also generates blockchain keys based on its own information and user information. When the device communicates with the cloud platform, the two keys are verified to achieve secure communication between the device and the cloud platform.

[0035] Blockchain is a chain of blocks. Each block stores certain information. They are connected into a chain in the order of their generation. This chain is stored in all servers. As long as there is one server in the entire system that can work, the entire blockchain is safe. These servers are called nodes in the blockchain system. They provide storage space and computing power support for the entire blockchain system. If you want to modify the information in the blockchain, you must obtain the consent of more than half of the nodes and modify the information in all nodes. These nodes are usually in the hands of different entities. Therefore, it is extremely difficult to tamper with the information in the blockchain. Compared with traditional networks, blockchain has two core characteristics: one is that data is difficult to tamper with, and the other is decentralization. Based on these two characteristics, the information recorded in the blockchain is more authentic and reliable, which can help solve the problem of people's distrust.

[0036] With the rapid development of science and technology, blockchain technology has begun to be applied. The security, decentralization and independence of blockchain technology have been recognized by many people. Based on blockchain technology, a safer and more convenient smart home system can be realized.

[0037] According to one aspect of the embodiments of the present application, the present application provides a device control method, which is applied to a device end, such as Figure 2 As shown, including:

[0038] Step 201, when it is detected that the verification interface of the target device is triggered, target data of the target object is collected according to the verification policy corresponding to the target device;

[0039] Step 203, sending the target data to the blockchain to generate an object key in the blockchain;

[0040] Step 205, authenticate the object key, and if the authentication is passed, encrypt the device data and target data of the target device through the blockchain to generate a first key;

[0041] Step 207: forward the first key and the received control instruction to the cloud platform, so that the cloud platform controls the target device to perform the operation corresponding to the control instruction when the first key and the second key are successfully verified, wherein the second key is generated by the historical usage data of the target device and the cloud platform data of the cloud platform through the blockchain.

[0042] The target object needs to be authenticated before using the target device, so the target object needs to send a verification request to the target device first. The way to send the verification request is not limited.

[0043] When it is detected that the target object has triggered the verification interface, the target data of the target object is collected, and then the target data is encrypted using the blockchain to obtain the object key, which is also the first blockchain key in the device control process of this application. The first key and the second key mentioned below are all blockchain keys.

[0044] Verifying the object key is to match the current object key with the key in the previously stored database. A successful match means that the verification is successful. If a key matching the object key cannot be found in the database, it means that the target object does not have permission to use the target device.

[0045] As an optional embodiment, collecting target data of the target object according to the verification strategy corresponding to the target device includes: obtaining the security level of the target device; collecting biometric information matching the security level, and performing feature extraction on the biometric information to obtain biometric features; and determining the biometric features as target data.

[0046] Optionally, the security factor of the device is different, and the corresponding security level is also different. The device with a high security level requires a higher degree of verification, and the more information needs to be verified.

[0047] Since the biological characteristics of the human body are unique, this application uses the biological characteristics as the target data to be verified.

[0048] As an optional embodiment, the security level includes at least two levels, and collecting biometric information matching the security level includes: obtaining a preset number corresponding to the security level, wherein a higher security level corresponds to a greater number of corresponding preset numbers; and collecting a preset number of biometric information of a biological category.

[0049] The security level is at least two levels, and the optional embodiment provided by the present application includes three levels. Under different security levels, biological information of different preset numbers of biological categories is collected, wherein the security level corresponds to the preset number.

[0050] When the security level is the first level, the biological information of the first category in the preset biological category is collected, wherein each category in the preset biological category is a biological category pre-entered by the user using the target device; when the security level is the second level, the biological information of the second category in the preset biological category is collected, wherein the second level is lower than the first level, and the number of categories in the second category is less than the number of categories in the first category; when the security level is the third level, the biological information of the third category in the preset biological category is collected, wherein the third level is lower than the second level, and the number of categories in the third category is less than the number of categories in the second category. In the above example, the device corresponding to the first level has the highest safety factor, and the device corresponding to the third level has the lowest safety factor.

[0051] Optionally, the preset biometric categories include but are not limited to fingerprint, voiceprint, face and iris.

[0052] For example, the preset biometric categories are fingerprint, voiceprint and face. The smart device establishes a three-level security level based on the usage scenario of the target device. A device with a security level of one will verify the user's fingerprint, face and voiceprint when in use. A device with a security level of two will verify any two of the user's fingerprint, face and voiceprint when in use, and so on. The user verification system based on classification takes into account both security and convenience.

[0053] As an optional embodiment, after the identity authentication is passed, the method also includes: obtaining the historical verification record of the target object; extracting the historical biometric information of the latest preset number of verification times from the historical verification record; performing feature extraction on the historical biometric information to obtain the target feature; encrypting the target feature through the blockchain to obtain the target object key, and updating the target object key to the database of the blockchain, wherein the database is used to store multiple pre-generated object keys.

[0054] The historical verification record of the target object is the verification record of the target user when using the device (not limited to the target device) before. The historical verification record includes all the biometric information collected each time and the verification time of the target object.

[0055] The latest verification time is the most recent verification time at the current moment. The preset number of times can be set by yourself (for example, 10 times), and the setting standard can be based on age or gender. For example, for the authentication and recognition of smart door locks, for a 5-year-old child, growth changes will affect the face, so the preset number of times can be more, and for a 25-year-old adult, the corresponding preset number can be less; the corresponding preset number for women can be more, because women may wear makeup, which may slightly change the presented face.

[0056] For example, the blockchain-based identity authentication and identification system requires the user to enter his or her fingerprint information, facial information, and voiceprint information, extract features from the collected information, encrypt the extracted identity feature information with the blockchain, generate the user's identity key, and then store it in the database.

[0057] For example, feature extraction is performed again based on the user's biometric information collected ten times recently, and a new user identity key is generated in the blockchain to achieve real-time and stability of the key.

[0058] According to one aspect of the embodiments of the present application, the present application provides a device control method, which is applied to a cloud platform, such as Figure 3 As shown, including:

[0059] Step 301, upon receiving a control instruction sent by the device, encrypting the cloud platform data and the historical usage data of the target device using the blockchain to generate a second key, wherein the historical usage data is generated by the historical usage record of the target device;

[0060] Step 303: Pair the second key with the first key, and if the pairing is successful, control the target device to perform an operation corresponding to the control instruction, wherein the first key is obtained by encrypting the target data and the device data of the target device by the blockchain.

[0061] The cloud platform is connected to the device side to control the target device.

[0062] When receiving a control instruction sent by the device, the second key of the cloud platform is first generated using the blockchain, and then the second key is mutually verified with the first key of the device. After the verification is passed, the target device is controlled to perform the operation corresponding to the control instruction.

[0063] Blockchain is used to encrypt cloud platform data and historical usage data of target devices. The historical usage data of target devices is data pre-existing in the blockchain network, including usage records of target devices and user information.

[0064] In order to ensure that smart home devices are not hacked and to achieve secure communication with the cloud platform, the device side encrypts the device information and user identity information in the blockchain to generate the device side key. The cloud platform that controls the device will also generate the cloud platform side key in the blockchain based on its own information, the controlled device (target device) information, and the user information. Before the device side uploads the received instructions to the cloud platform, the two keys will also verify each other, and new keys will be regenerated on both ends based on the latest user keys. After verification, the cloud platform controls the target device according to the control instructions, thereby preventing the device from being hacked.

[0065] Based on blockchain technology, the smart home system can associate each use record of smart home devices with the cloud platform and smart devices respectively. Due to the security of blockchain, it is impossible to modify the data in the blockchain without controlling 51% of the data nodes. Therefore, the device usage history record is combined with the key of the device and the cloud platform as the basis for verifying the identity of the device and the cloud platform, so as to achieve more secure and reliable control of smart home devices.

[0066] The present application adopts a device control system, including: a device end, which is used to collect target data of a target object according to a verification strategy corresponding to the target device when detecting that a verification interface of a target device is triggered; send the target data to a blockchain to generate an object key in the blockchain; authenticate the object key, and when the identity authentication is passed, encrypt the device data and the target data of the target device through the blockchain to generate a first key; forward the first key and the received control instruction to a cloud platform, so that when the cloud platform successfully authenticates the first key and the second key, it controls the target device to perform an operation corresponding to the control instruction, wherein the second key is a historical key of the target device authenticated through the blockchain. The cloud platform, upon receiving the control instruction sent by the device, uses the blockchain to encrypt the cloud platform data and the historical usage data of the target device to generate a second key, wherein the historical usage data is generated by the historical usage record of the target device; the second key is paired with the first key, and when the pairing is successful, the target device is controlled to perform the operation corresponding to the control instruction; the blockchain network is connected to the device and the cloud platform respectively, and is used to encrypt the target data sent by the device to generate an object key; the device data and target data of the target device are encrypted to generate the first key; the historical usage data and the cloud platform data are encrypted to generate the second key. The device data and user data are encrypted through the blockchain network, and the historical usage data and the cloud platform data are encrypted, and the encrypted keys are mutually verified. According to the verification result, it is determined whether to control the device, which solves the problem of low safety factor of the device.
