Detailed Description
The operation control method of the intelligent household equipment realizes log storage and related operation control of the intelligent household equipment by combining the block chain.
The blockchain is a novel application mode of computer technologies such as distributed data storage, point-to-point transmission, a consensus mechanism and an encryption algorithm. The Blockchain (Blockchain) is essentially a decentralized database, which is a series of data blocks associated by using a cryptographic method, and each data block contains information of a batch of network transactions, so as to verify the validity (anti-counterfeiting) of the information and generate the next block. The blockchain may include a blockchain underlying platform, a platform product services layer, and an application services layer.
The block chain underlying platform can comprise processing modules such as user management, basic service, intelligent contract and operation monitoring. The user management module is responsible for identity information management of all blockchain participants, and comprises public and private key generation maintenance (account management), key management, user real identity and blockchain address corresponding relation maintenance (authority management) and the like, and under the authorization condition, the user management module supervises and audits the transaction condition of certain real identities and provides rule configuration (wind control audit) of risk control; the basic service module is deployed on all block chain node equipment and used for verifying the validity of the service request, recording the service request to storage after consensus on the valid request is completed, for a new service request, the basic service firstly performs interface adaptation analysis and authentication processing (interface adaptation), then encrypts service information (consensus management) through a consensus algorithm, transmits the service information to a shared account (network communication) completely and consistently after encryption, and performs recording and storage; the intelligent contract module is responsible for registering and issuing contracts, triggering the contracts and executing the contracts, developers can define contract logics through a certain programming language, issue the contract logics to a block chain (contract registration), call keys or other event triggering and executing according to the logics of contract clauses, complete the contract logics and simultaneously provide the function of upgrading and canceling the contracts; the operation monitoring module is mainly responsible for deployment, configuration modification, contract setting, cloud adaptation in the product release process and visual output of real-time states in product operation, such as: alarm, monitoring network conditions, monitoring node equipment health status, and the like.
The platform product service layer provides basic capability and an implementation framework of typical application, and developers can complete block chain implementation of business logic based on the basic capability and the characteristics of the superposed business. The application service layer provides the application service based on the block chain scheme for the business participants to use.
In the embodiment of the application, the smart home devices are added to the block chain network, and each smart home device is used as a node in the block chain.
For convenience of understanding, the structure of the blockchain network where the smart home devices are located in the present application is described first.
Fig. 1 is a block chain network structure diagram for the present application.
As shown in fig. 1, the blockchain network (also referred to as a blockchain for short) includes a plurality of smart home devices 101, which are connected to each other through a network.
Each smart home device 101 is a node in the block chain network, and therefore each smart home device has a part of storage space as a storage area of a storage block in the block chain.
Correspondingly, each intelligent home device can store data such as logs and the like stored in the blockchain network by other intelligent devices in the blockchain network; each smart home device can also broadcast data such as logs generated by the smart home device to each node of the blockchain network, so that the data such as the logs can be stored in the blockchain network.
In the embodiment of the application, each smart home device applies for joining in a block chain network composed of a plurality of smart home devices in an initialization process, so that the smart home device becomes a node of the block chain network.
Optionally, in order to reduce network pressure, after the multiple smart home devices of the same user join the blockchain network, the multiple smart home devices of the same user may be used as a set having an association, so that the blockchain network only stores one piece of data related to the user, and does not need to store the user-related data repeatedly.
The process of adding the intelligent household equipment into the block chain network can be realized in various ways, and the method is not limited by the application.
For example, in one possible scenario, the blockchain network may include at least one server maintained by a vendor of smart home devices, e.g., a smart home server. In this case, the at least one server all belong to a node of the blockchain network, and therefore, the smart home device may apply for joining the blockchain network to the server already joined to the blockchain network and nodes such as other smart home devices.
Of course, in practical application, it is only necessary to ensure that each smart home device joins the blockchain network. The nodes of the block chain network may all be smart home devices, or may include servers of the smart home devices, and may be specifically set as needed.
It can be understood that the types of the smart home devices in the blockchain network may be different, for example, the smart home devices in the blockchain network may include a smart television, a smart speaker, a smart air conditioner, or the like.
As shown in fig. 2, which shows a schematic structural diagram of an intelligent home device according to the present application, the intelligent home device of this embodiment at least includes: a processor 201, a memory 202, and a communication interface 203.
The processor 201 may be a Central Processing Unit (CPU), an application specific integrated circuit, a Digital Signal Processor (DSP), a Field Programmable Gate Array (FPGA), or other programmable logic devices.
The processor may call a program stored in the memory 202, and in particular, the processor may perform related operations on the smart home device side in the following embodiments of fig. 3 to fig. 6.
The memory 202 is used for storing one or more programs, which may include program codes including computer operation instructions, and in the embodiment of the present application, the memory stores at least the programs for implementing the following functions:
receiving an operation control instruction for controlling the intelligent household equipment;
generating a log related to the operation control instruction;
storing the log to the blockchain;
after confirming that the log is successfully stored in the blockchain, executing the operation task indicated by the operation control instruction.
The communication interface 203 may be an interface of a communication module that may enable storing the log into a blockchain.
Optionally, the smart home device may further include an input unit 204, such as a voice input interface or a touch screen.
The smart home device may also include a display screen 205 or the like.
The processor 201, the memory 202, the communication interface 203, the input unit 204, and the display 205 all communicate with each other through the communication bus 206.
Of course, the structure of the smart home device shown in fig. 2 does not constitute a limitation on the smart home device in the embodiment of the present application, and in practical applications, the smart home device may include more or less components than those shown in fig. 2, or some components in combination.
The operation control method of the smart home device according to the present application is described below with reference to a flowchart.
As shown in fig. 3, which shows another flowchart of the operation control method for smart home devices according to the present application, the method of the present embodiment may be applied to the smart home devices in the aforementioned block chain. The method of the embodiment may include:
and S301, receiving an operation control instruction for controlling the intelligent household equipment.
The operation control instruction indicates an operation task to be executed by the intelligent household equipment. For example, the operation control instruction may be an instruction to start up, shut down, start up which function, or switch a certain mode, enter data, or the like.
It can be understood that there are many possible ways in which the smart home device receives the operation control instruction, for example, the smart home device may receive the operation control instruction input by the user through an input interface (such as a touch screen or a voice input interface) of the smart home device. For another example, the smart home device may receive an operation control instruction transmitted by a controller of the smart home device, where the controller of the smart home device may be a remote controller matched with the smart home device, or a mobile terminal such as a mobile phone for controlling the smart home device.
Accordingly, the operation control command may be in various forms according to the receiving form of the operation control command, for example, the operation control command may be a voice control command or an input control signal.
S302, a log related to the operation control command is generated.
It can be understood that the operation control instruction is used to instruct the smart home device to point to an operation task, and the operation control instruction can determine the operation task that the smart home device needs to execute, so that the log associated with the operation control instruction can record at least information associated with the operation task indicated by the operation control instruction.
Optionally, before generating the log, the smart home device may further determine an operation task indicated by the operation control instruction. And then, generating a log containing the relevant information of the operation task according to the operation task indicated by the operation control instruction.
The smart home device can analyze the operation control instruction to obtain an operation task indicated by the operation control instruction. For example, the smart home device may analyze an operation control instruction input by a user, and determine information of an operation task included in specific content of the operation control instruction.
In a possible situation, considering that under the condition that the user controls the smart home devices through the network, the operation control instructions of most of the smart home devices need to be analyzed through the smart home server, the operation control instructions received by the smart home devices may also be forwarded to the smart home control devices through the smart home server. Under the condition, the operation task indicated by the operation control instruction is analyzed by the intelligent home equipment and fed back to the intelligent home equipment, so that the intelligent home equipment can directly obtain the operation task indicated by the operation control instruction.
Of course, after the smart home device receives the operation control instruction directly input by the user or input by another controller, the smart home device may also transmit the operation control instruction to the smart home server, so as to determine the operation task indicated by the operation control instruction by the smart home server. In practical applications, the above methods for determining the operation task indicated by the operation control command and the other methods for determining the operation task indicated by the operation control command are all applicable to the present application.
It can be understood that the log recorded by the smart home device is to facilitate checking a fault existing in the smart home device, optimizing a service of the smart home device, or checking whether an illegal intrusion exists, and the like, and therefore, the log recorded by the smart home device and related to the operation control instruction may include information of multiple dimensions related to the operation task indicated by the operation control instruction.
For example, the log related to the operation control instruction may record, in addition to the operation task indicated by the operation control instruction, the operation type to which the operation task belongs, the reception time of the operation control instruction (or a time stamp including the generation time of the log), and the like.
In addition, since the log generated by the smart home device is stored in the blockchain, in order to distinguish which smart home device the log originates from in the blockchain, the log may further record a device identifier of the smart home device. Correspondingly, the log may also record a user identifier corresponding to the user to which the smart home device belongs, such as identification information of a user name, an account number, and the like.
S303, store the log to the block chain.
For example, the smart home device broadcasts the log to each node in the block chain, so that the log is saved in a block maintained by each node in the block chain.
According to different types of the block chain, the specific way in which the intelligent home device serving as the node in the block chain stores the log into the block chain may also be different.
Accordingly, the form in which the log is stored in the blockchain may be various. For example, in one possible case, the log may be stored in the form of a key-value pair. Specifically, a key for identifying the log is generated for the log, then the log is used as a value in a key value pair, and a key value pair association formed by the key and the value is stored in the block chain.
It can be understood that, after the logs are stored in the plurality of nodes of the block chain, even if data of the node, which is the smart home device, is damaged by malicious intrusion and deleted, the logs are still stored in other nodes of the block chain, so that the log can be prevented from being lost due to deletion.
Moreover, the blockchain has the characteristic of data tamper resistance, and the stored logs of the blockchain cannot be tampered, so that the authenticity and the reliability of the logs in the blockchain are guaranteed, and a reliable basis is provided for subsequent log-based correlation analysis.
S304, after confirming that the log is successfully stored in the block chain, executing the operation task indicated by the operation control instruction.
In order to ensure that the logs corresponding to the operation tasks executed by the intelligent home equipment are reliably stored in the block chain, the operation tasks indicated by the operation control instructions are executed after the intelligent home equipment confirms that the logs are successfully stored in the block chain, so that the reliable storage of the logs is ensured, and the condition that log information corresponding to the operation tasks executed by the intelligent home equipment is omitted is reduced.
After the intelligent home device sends the log to each node in the block chain, each node in the block chain notifies the intelligent home device after the log is successfully stored, so that the intelligent home device can obtain whether the log is successfully stored in the block chain according to a storage result of the log fed back by each node in the block chain.
It can be understood that, during the process of executing the operation task by the smart home device, the smart home device may still generate some logs related to the execution state of the operation task, and for convenience of distinction, the logs related to the execution state and generated during the process of executing the operation task are referred to as state logs. In order to ensure the safety of the state log, the state log may be stored in the block chain after the smart home device generates the state log related to the execution state of the operation task.
According to the method, the intelligent home devices are added into the block chain as the nodes, meanwhile, logs which are generated by the intelligent home devices and related to the operation control instructions can be stored in the block chain, and the block chain has the data tamper-proof characteristic, so that the logs of the intelligent home devices stored in the block chain can be prevented from being tampered. Moreover, even if the smart home device is invaded and the log stored in the smart home device is deleted, the smart home device can still obtain the log of the smart home device from the block chain, so that the risk that the log of the smart home device is tampered or lost is reduced, and the safety of the log of the smart home device is improved.
It is understood that some logs generated by the smart home device may belong to sensitive logs, where the sensitive logs refer to data related to user privacy, or data that the user does not want to be seen by other users besides the user, and the like. If the sensitive log relates to private data, once the sensitive log is spread maliciously, the sensitive log will have a bad influence. Therefore, in order to avoid the sensitive log being seen by users of other smart home devices in the block chain, the sensitive log can be encrypted before being stored.
As shown in fig. 4, which shows a flowchart of another embodiment of the operation control method for smart home devices according to the present application, the present embodiment is still applied to the smart home devices in the aforementioned block chain. The embodiment may include:
s401, receiving an operation control instruction for controlling the intelligent household equipment.
S402, a log related to the operation control instruction is generated.
The above steps S401 and S402 can refer to the description of the relevant steps in the previous embodiment.
And S403, determining the operation type to which the operation task indicated by the operation control instruction belongs.
The manner of determining the operation task indicated by the operation control instruction may refer to the related description above.
The operation type represents the category to which the specific content executed by the operation task belongs. For example, the operation types may include some or all of the following:
system configuration of the smart home devices, for example, setting and controlling related parameters related to a device connection mode, a message display mode, a working state and the like of the smart home devices;
user personal information configuration, for example, a task of configuring information such as names, contact addresses or fingerprints representing personal information;
private information input, such as storage of voice input by a user or personal images, etc.;
user personality settings, such as working hours, lighting modes, etc., of the smart home device;
and the intelligent household equipment normally works, such as starting up, shutting down, mode switching, working mode setting and the like.
Of course, the above is only described by taking the case of several operation types as an example, and in practical application, the operation types may be divided as needed.
Wherein, the operation type of the operation task can be determined according to the specific content of the operation task. For example, the correspondence between different operation tasks and operation types may be preset, and the operation type corresponding to the operation task may be determined.
S404, when the operation type of the operation task belongs to the set sensitive operation type, the log is encrypted by the set public key to obtain an encrypted log.
The sensitive operation type refers to an operation type to which an operation task which can relate to user private data belongs, or an operation type to which an operation task which can generate some critical data belongs. In particular, if the data involved in performing the operation task of the operation type or the data generated relates to sensitive data, the operation type may be set to the sensitive operation type. For example, the operation task related to the configuration of the user personal information may relate to the user personal information, and the operation type to which the operation task related to the configuration of the user personal information belongs may belong to the sensitive operation type.
Of course, in practical application, the sensitive operation type can be set according to the requirement.
It can be understood that, since the operation task corresponding to the execution of the sensitive operation type may involve some sensitive data such as user private data, if the operation task indicated by the operation control instruction belongs to the sensitive operation type, the generated log related to the operation control instruction or the operation task may also involve the sensitive data. In this case, the generated log related to the operation control instruction may be regarded as a sensitive log, and therefore, the log needs to be encrypted. Specifically, the log may be encrypted by using a set public key.
The set public key is an encryption key set by a user of the intelligent household equipment. Correspondingly, the encrypted log can be decrypted only by using a decryption key of the user of the intelligent household equipment.
S405 stores the encrypted log in the blockchain, and S407 is performed.
The way of storing the encrypted log is similar to the process of directly storing the log in the process, for example, a key value pair form may be adopted, a key is generated for the encrypted log, the encrypted log is used as a value, and the encrypted log and the corresponding key are stored into the block chain as a key value pair.
It can be understood that, since the logs generated in the smart home device include the normal logs and the sensitive logs related to the sensitive data, in order to facilitate distinguishing the sensitive logs in the blockchain, after obtaining the encrypted logs, an identifier including a sensitive distinguishing mark may be generated for the encrypted logs. This identifier is then stored in association with the encrypted log to the blockchain.
The specific form of the identifier containing the sensitive distinguishing mark may be various, for example, the identifier may be a special character added to the serial number of the log. Alternatively, where the log is stored in the form of key-value pairs, keys containing sensitive distinguishing characters may be generated for the encrypted log. For example, a special character string is added to the key. Accordingly, the encrypted log can be used as a value corresponding to the key, and a key-value pair formed by the encrypted log and the key containing the sensitive distinguishing character can be stored in the block chain.
S406, if the operation type does not belong to the set sensitive operation type, directly storing the generated log to the block chain, and performing S407.
If the log does not belong to sensitive data, then the log does not belong to a sensitive log, in which case the log may be stored directly into the blockchain.
S407, after confirming that the log is successfully stored in the blockchain, executing the operation task indicated by the operation control command.
This step S407 can refer to the related description of the previous embodiment, and is not described herein again.
Therefore, in the embodiment of the application, after the smart home device generates the log of the operation control instruction, if the operation type indicated by the operation control instruction belongs to the sensitive operation type, the smart home device may confirm that the log is the sensitive log, encrypt the log by using the set public key, and store the encrypted log into the block chain, so that the sensitive log related to the sensitive data such as user privacy and the like can be prevented from being exposed, and on the premise of ensuring that the sensitive log is not lost and tampered, the risk of the sensitive log being leaked is reduced.
It can be understood that, on the basis of the embodiment of fig. 4, if a user needs to read a sensitive log stored in a block chain, that is, an encrypted log, the smart home device may decrypt the log only after acquiring a private key of the user, so that even if another person acquires the encrypted log, the specific content of the log cannot be decrypted.
Further, in order to improve the security of the encrypted log, the smart home device of the present application needs to decrypt the encrypted log by using the private key provided by the user after obtaining the authorization of the user to encrypt the sensitive log. As shown in fig. 5, which shows a schematic flow chart of reading a sensitive log in an operation control method of an intelligent home device in the embodiment of the present application, the embodiment may be applied to an intelligent home device, and the flow chart includes:
s501, responding to a log reading instruction, reading a target log indicated by the log reading instruction from the block chain.
For the sake of convenience of distinction, the log read by the log read instruction is referred to as a target log. Of course, the target log requested to be read by the log reading instruction may be one or more logs.
For example, the log reading instruction may be an instruction to read a log stored in the block chain by the smart home device within a specified time period.
S502, if the encrypted log is included in the target log, an authorization prompt is output.
The smart home device determines that the target log contains an encrypted log, and may detect that the encrypted log exists in the target log after the target log is read.
Optionally, when the encrypted log is stored in the block chain and the identifier corresponding to the encrypted log and including the sensitive distinguishing mark is stored, if the smart home device detects that the read target log includes the identifier log corresponding to the identifier log, it is determined that the target log includes the encrypted log.
It can be understood that, if the read target log is an encrypted log or contains an encrypted log, it indicates that the read target log contains a sensitive log, and in this case, the smart home device may output an authorization prompt prompting the user to input authorization information.
The authorization prompt is used for prompting a user of the intelligent household equipment to input authorization information.
It can be understood that, according to different control modes of the smart home device for controlling the smart home device by the user of the smart home device, the specific form of the authorization prompt output by the smart home device may also be different. For example, if a user of the smart home device sends a log reading instruction to the smart home device through a mobile terminal such as a mobile phone, the smart home device may send an authorization prompt to the mobile terminal of the user. For another example, if the user of the smart home device inputs the log reading instruction to the smart home device through the remote controller or directly, and the smart home device may output the authorization prompt through the display screen or the voice output unit.
The authorization prompt informs the user of inputting authorization information, and meanwhile, an operation of reading the sensitive log exists, so that if the user really reads the sensitive log, the user can input information representing the identity of the user to finish authorization; if the log reading instruction for reading the sensitive log is not the instruction sent by the user, the user can not input the identity information, so that authorization is refused, and other people are prevented from illegally obtaining the sensitive log.
S503, under the condition that the authorization information input by the user of the intelligent household equipment is obtained and carries the private key of the user, the private key is used for decrypting the encrypted log to obtain the decrypted log.
Similar to the foregoing authorization prompt output by the smart home device, the smart home device may obtain authorization information that is directly input to the smart home device by the user or is sent to the smart home device by a control device such as a mobile terminal.
In one possible case, the authorization information may be an indication that the user agrees to read the encrypted log. Optionally, to avoid others disguising the user, the authorization information may include authentication information of the user, such as a voiceprint, a fingerprint, or a face image of the user.
Correspondingly, after the received authorization information is verified to be the authorization information of the user, the smart home device can confirm that the user of the smart home device is authorized to read the encrypted log.
It can be understood that, in order to ensure the security of the encrypted sensitive log, the private key needs to be provided by the user of the smart home device, but cannot be preset in the smart home device, so that the private key for decrypting the sensitive log can be provided while the user provides the authorization information
The private key and the set public key are a pair of key pairs. That is to say, the private key is a decryption key corresponding to the public key used by the encryption log.
Therefore, after the encrypted log is read from the block chain, the intelligent home device can decrypt the encrypted log according to the private key provided by the user only after the authorization of the user is obtained, so that the security of sensitive data in the encrypted log is ensured, and the risk of leakage of the sensitive data is reduced.
For convenience of understanding the solution of the present application, the following introduces the solution of the present application in combination with an application scenario, so as to store a log in a block chain in a key-value pair manner, and take an example that a user of an intelligent home device utilizes a mobile phone and controls the intelligent home device through a network as an illustration, for example, referring to fig. 6, which shows a flowchart of another embodiment of an operation control method of an intelligent home device according to the present application, where the method of the embodiment includes:

And S602, the intelligent home control device determines the operation task indicated by the operation control instruction, the operation type of the operation task and the user identifier corresponding to the user sending the operation control instruction.
For specific implementation manners of determining the operation task and the operation type of the operation task, reference may be made to related descriptions in the foregoing embodiments, and details are not described herein again.
And S603, the intelligent household control equipment generates a log containing the operation task, the operation type, the user identifier and the equipment identifier of the intelligent household control equipment.
Of course, the log may also include a time stamp of the time at which the log was generated, or information of the time at which the operation control instruction was received.
And S604, encrypting the log by using the set public key to obtain the encrypted sensitive log under the condition that the intelligent household equipment confirms that the operation type of the operation task belongs to the set sensitive operation type.
And S605, the intelligent household equipment generates a key containing the sensitive distinguishing mark for the encrypted sensitive log, forms a key value pair with the encrypted sensitive log and stores the key value pair into a block chain, and executes S607.
And S606, under the condition that the operation type does not belong to the set sensitive operation type, the intelligent home equipment generates a key for the generated log, stores the key and the log to a block chain in a key value pair mode, and executes S607.
If the log does not belong to sensitive data, then the log does not belong to a sensitive log, in which case the log may be stored directly into the blockchain.
S607, after the smart home device confirms that the log is successfully stored in the blockchain, the operation task indicated by the operation control instruction is executed.
S608, the user sends a log reading instruction to the intelligent household equipment through the mobile terminal.
And S609, the intelligent household equipment responds to the log reading instruction and reads the target log from the block chain.
And S610, sending an authorization prompt to a mobile terminal of a user under the condition that the intelligent household equipment confirms that the read target log contains the encrypted sensitive log.
S611, the mobile terminal feeds back the authorization information carrying the private key of the user to the intelligent household equipment.
And S612, if the smart home device confirms that the authorization information is the authorization information of the user with the authority, the encrypted sensitive log is decrypted by using the private key to obtain the encrypted sensitive log.
Of course, the smart home device may also feed back a target log including the decrypted sensitive log to the mobile terminal of the user, so that the user can view the target log conveniently.
