[0102] Embodiment 1

[0103] Fig. 1 is a flowchart illustrating a method of realizing an intelligent device system provided by the present invention, as shown in Fig. 1, the method can comprise the following steps.

[0104] 101 - constituting a private blockchain network out of a plurality of intelligent devices accessed to a local area network.

[0105] The plural intelligent devices include, but are not limited to, smart locks, smart speakers, intelligent air-conditioners, intelligent television sets, and intelligent routers, etc. The intelligent device can utilize a sensor to collect such information as user fingerprint data and environmental data, etc., and the sensor can be either integrated on the intelligent device or connected with the intelligent device via a wired mode or a wireless mode.

[0106] 102 - obtaining, by each of the intelligent devices, a smart contract having a plurality of functions released by a user, and deploying the smart contract onto the private blockchain network after confirmation by the user.

[0107] The smart contract possesses plural functions, including addition function, deletion function, query function, modification function, and verification function.

[0108] Specifically, the process can include the following:

[0109] The various intelligent devices respectively obtain the smart contract released by the user through one of the following modes:

[0110] a client end having a contract releasing function;

[0111] an intelligent device from the plural intelligent devices having a contract releasing function;

[0112] the client end can specifically be such a terminal device as a mobile terminal, a personal PC, etc.

[0113] After confirmation of the user by pressing a button, the various intelligent devices deploy the smart contract onto the private blockchain network.

[0114] 103 - obtaining, by the intelligent device, user sensitive data in a device initialization request, when the intelligent device receives the device initialization request from the user.

[0115] The user sensitive data can be such user characteristic information as fingerprint data and iris data of the user, and other sensitive data can be further included.

[0116] In this embodiment, after the user has deployed the plural intelligent devices to constitute the private blockchain network, it is required to initialize the intelligent devices to facilitate subsequent use of the intelligent devices. When it is required for the user to initialize an intelligent device, initialization can be performed by fingerprint input, taking a smart lock for example, the user can input his fingerprint data via a sensor in the smart lock, so as to initialize the smart lock.

[0117] 104 - generating corresponding first initial information for the user sensitive data, and invoking an addition function of the smart contract to write the first initial information in a private blockchain.

[0118] Specifically, the intelligent device converts the initial fingerprint data to an initial hash value, and generates an initial composite key according to the initial hash value and a device ID of the intelligent device; a value is generated according to a start mode of the intelligent device and an entry time of the initial fingerprint data; the initial composite key and the value are correspondingly written in a private blockchain through the addition function of the smart contract.

[0119] During the process of specific implementation, the intelligent device can employ a hash algorithm to perform hash computation on the initial fingerprint data, and to generate the initial hash value, and the hash algorithm can be any safe and reliable hash algorithm, such as SHA256, SM3 according to State Cryptography Administration or SM4 according to State Cryptography Administration, etc.

[0120] In this embodiment of the present invention, since the initial information generated by the user sensitive data is written in the private blockchain through the smart contract, and the content of the smart contract cannot be modified when a single intelligent device is broken through, the originally deployed smart contract can be evaded only by breaking through the entire intelligent devices in the private blockchain network to deploy a new smart contract, so it is difficult for illegal individuals to obtain the user sensitive data; moreover, the user sensitive data can only be operated and read by the user, so the user sensitive data is rendered more secure; at the same time, since the plural intelligent devices constituting the private blockchain network are accessed to the local area network, malicious attack by illegal individuals through the public network is made impossible; in addition, compared with prior-art technology in which the user must pass through the public network to access to the server for identification verification when the user sensitive data is stored in a cloud server, since the user sensitive data is stored in an LAN private blockchain according to the embodiments of the present invention, the user can directly access to the LAN for identification verification, so the ID verification is made more highly effective.

[0121] Moreover, the method provided by this embodiment of the present invention can further comprise:

[0122] invoking, when the intelligent device receives a modification request of the user sensitive data from the user, a modification function of the smart contract to modify the user sensitive data; and invoking, when the intelligent device receives a deletion request of the user sensitive data from the user, a deletion function of the smart contract to delete the user sensitive data.

[0124] Moreover, the method provided by this embodiment of the present invention can further comprise:

[0125] recording, by the intelligent device, operations on the user sensitive data in the private blockchain for the user's review and check.

[0126] In this embodiment of the present invention, by recording operations on the user sensitive data in the private blockchain, it is made possible to prevent the user sensitive data from being illegally enquired and tampered with, and hence to fully guarantee the privacy and safety of the user sensitive data.

[0129] 201 - obtaining, by the intelligent device, user input data in a device use request, when the intelligent device receives the device use request from the user.

[0130] In this embodiment, after the user has completed initialization of the intelligent device, the intelligent device can be correspondingly operated. Taking a smart lock for example, when it is required for the user to open the smart lock, the smart lock can be opened through fingerprint input, i.e., fingerprint data is input via a sensor in the smart lock.

[0131] 202 - generating corresponding information to be enquired for the user input data.

[0132] The user input data is fingerprint data of the user.

[0133] Specifically, the intelligent device converts the fingerprint data to a hash value, and generates a composite key according to the hash value and the device ID of the intelligent device to serve as the information to be enquired.

[0134] During the process of specific implementation, the intelligent device can employ a hash algorithm to perform hash computation on the user input data, and to generate the hash value, and the hash algorithm can be any safe and reliable hash algorithm, such as SHA256, SM3 according to State Cryptography Administration or SM4 according to State Cryptography Administration, etc.

[0135] 203 - invoking a query function of the smart contract to enquire the information to be enquired in the private blockchain.

[0136] Specifically, the query function of the smart contract is invoked to enquire whether there is a value that corresponds to the composite key in the private blockchain, and a query result returned by the smart contract is received. The query result is employed to indicate whether the intelligent device can be used and operated.

[0137] 204 - determining, by the intelligent device, whether a use operation is allowed according to a query result of the smart contract.

[0138] When the query result expresses successful query, the intelligent device is allowed to be used and operated, when the query result expresses failed query, the intelligent device is not allowed to be used and operated.

[0139] In this embodiment of the present invention, when the user is using the intelligent device, input data of the user is obtained and corresponding information to be enquired is generated, and corresponding query is performed by invoking the query function of the smart contract, so as to determine whether the intelligent device is allowed to be used and operated according to the query result returned by the smart contract, whereby it is made possible to prevent the intelligent device from being controlled by illegal individuals.

[0142] 301 - obtaining, when a client end of the user receives a device initialization request of the intelligent device of the user, by the client end, an initial password set by the user.

[0143] In this embodiment, after the user has deployed the plural intelligent devices to constitute the private blockchain network, it is required to initialize the intelligent devices to facilitate subsequent use of the intelligent devices. When it is required for the user to initialize an intelligent device, initialization of the intelligent device can be further performed by password input in addition to fingerprint input. Taking a smart lock for example, the user can employ a handset client end to set the door-opening password of the smart lock, so as to initialize the smart lock.

[0144] 302 - employing a preset algorithm to generate corresponding second initial information for the initial password.

[0145] The preset algorithm is a hash algorithm.

[0149] Specifically, after confirmation of the user by pressing a button, each intelligent device upgrades the smart contract.

[0150] In this embodiment of the present invention, since the second initial information generated by the initial password set by the user is written in the private blockchain through the smart contract, when it is required for the user to change the initial password, this can be achieved by upgrading the contract.
