Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the present disclosure. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
In the related art, an industrial cooking project usually includes a plurality of cooking devices, and each cooking device needs to manage the cooking device parameters of each cooking device when operating, and data security of the cooking device parameters acquired by each cooking device cannot be guaranteed and may be tampered.
The invention provides a cooking equipment data management method based on a block chain, which is applied to a block chain network formed by a plurality of cooking equipment nodes. A block chain network is formed by a plurality of cooking equipment nodes, and each cooking equipment node stores a complete block chain. The block chain can be provided with two types of blocks, namely an authentication type block and a verification type block, wherein the authentication type block records registration information of the cooking equipment corresponding to each cooking equipment node, and legality of the cooking equipment is guaranteed. In some examples, the authentication type block further records related information of the cooking appliance node, such as a physical address, a network access time, and the like. The check type block records the records of the cooking equipment parameters collected by each online cooking equipment node so as to ensure that the cooking equipment parameters collected by the cooking equipment nodes are legal. In some examples, each check type block further records a public key of a cooking device node and a first identifier generated according to the collected cooking device parameters. Taking the above application scenario as an example, specific steps of the cooking device data management method based on the block chain provided by the present invention are described below.
Referring to fig. 1, a first aspect of the present invention provides a cooking apparatus data management method based on a block chain, the method including:
and S1, the current cooking equipment node generates signature identification information according to the collected cooking equipment parameters.
The signature identification information may include the signature information and the first identifier, and of course, in some examples, the signature identification information may also include other information, which is not limited herein.
Specifically, referring to fig. 2, S1 may include:
and S11, signing the cooking equipment parameters by using the prestored private key to generate signature information.
When a cooking equipment node is accessed to a block chain network for the first time, an asymmetric encryption algorithm can be adopted to generate a matched private key and a matched public key, the private key is stored in a local storage of the cooking equipment corresponding to the cooking equipment node, then the public key and relevant information of the cooking equipment node are generated into registration information, and an authentication type block is generated and stored in a block chain to serve as a basis for authenticating the legality of the cooking equipment node. And then after the current cooking equipment node collects the cooking equipment parameters, the locally stored private key address can be adopted to digitally sign the cooking equipment parameters to generate signature information.
It should be noted that the cooking device parameters may include various types of data, such as temperature, operation time, operation mode, pressure inside the oven, and the like of the cooking device, and are not limited herein.
And S12, generating a first identifier according to the preset algorithm and the parameters of the cooking equipment.
Specifically, the preset algorithm may be a hash algorithm, such as the SHA-256 algorithm, but may also be other hash algorithms, which is not limited herein. And hashing the collected cooking equipment parameters according to a hashing algorithm to generate a first identifier, namely generating short characteristic character strings with fixed byte length for the cooking equipment parameters collected by the cooking equipment nodes in a specific time, wherein the characteristic character strings are the first identifier and are also called the hashing identifier. And generating a first broadcast message by using the signature identification information containing the signature information and the first identification, and broadcasting the first broadcast message to other cooking equipment nodes in the block chain network. After receiving the first broadcast message written to the signature identification information, the other cooking equipment nodes can match and check the private key carried in the signature information in the signature identification information with respect to the public key of the current cooking node prestored in the block chain, and if the private key passes the check, the signature identification information is determined to be collected by a legal cooking equipment node, so that the first identification in the signature identification information and the public key of the current cooking equipment node can be generated into a check type block, and the collection is recorded in the block chain.
Referring to fig. 2, in some examples, before the S1 generating signature identification information by the current cooking device node according to the collected cooking device parameters, the method further includes:
and S02, broadcasting a second broadcast message carrying the registration information corresponding to the currently accessed cooking equipment node, enabling other cooking equipment nodes to receive the second broadcast message, judging whether the currently accessed cooking equipment node is allowed to access the block chain network according to the registration information corresponding to the currently accessed cooking equipment node, and if so, generating an authentication type block in the block chain to record the registration information corresponding to the currently accessed cooking equipment node.
Specifically, before S1, each cooking appliance node first accesses the blockchain network, and registration authentication is performed. Specifically, prior to S02, the method further comprises:
and S01, generating registration information corresponding to the cooking equipment node currently accessed to the block chain network.
Wherein S01 includes:
and S011, generating a public key and a private key which are matched according to a preset asymmetric encryption algorithm.
Specifically, before each cooking equipment node is firstly accessed to the block chain network, the cooking equipment node firstly generates a public key and a private key which are matched according to a preset asymmetric encryption algorithm.
In some examples, the asymmetric encryption algorithm may include an RSA algorithm or an elliptic curve algorithm, but of course, other methods may be used to generate the private key and the public key, which are not limited herein.
And S012, storing the private key, and generating registration information corresponding to the cooking equipment node of the current access block chain network according to the public key and the cooking equipment related information.
Specifically, after the cooking device node that is accessed for the first time generates the public key and the private key, the private key is stored in the local storage of the node, and the public key corresponding to the private key and the relevant information of the cooking device are generated into registration information.
When a cooking equipment node is accessed to the block chain network for the first time, the cooking equipment node accessed to the block chain network broadcasts a second broadcast message carrying the registration information of the cooking equipment node to other cooking equipment nodes in the block chain network, the other cooking equipment nodes check the registration information according to a preset rule and determine whether the cooking equipment node currently accessed to the block chain network agrees to access to the block chain network, and only if more than 51% of the cooking equipment nodes on the network agree to access to the cooking equipment node currently accessed to the block chain network, the cooking equipment node currently accessed to the block chain network is formally accessed to the network, so that false or malicious equipment can be prevented from accessing to the block chain network. After the cooking equipment node of the current access block chain network is allowed to access the network, generating an authentication type block from the registration information of the current access block chain network and storing the authentication type block into the block chain so as to confirm the legality of the cooking equipment of the current access block chain network. The preset rule may be, for example, that the cooking device node is pre-stored with a list of legal generators and physical addresses, and after receiving the second broadcast message, whether the cooking device corresponding to the current cooking device node is a legal cooking device is determined according to the physical address, the generator, and the like in the cooking device related information of the registration information in the second broadcast message. Of course, other preset rules may be set, and are not limited herein.
The information related to the cooking device node includes, for example, a physical address, a network access time, a manufacturer of the cooking device node, and the like.
In some examples, when any cooking device node in the blockchain network exits the blockchain network, the method further comprises:
and broadcasting a third broadcast message carrying the network quitting notification, so that other cooking equipment nodes receive the third broadcast message, and deleting the registration information of the corresponding cooking equipment nodes of the network quitting notification in the block chain.
Specifically, when a cooking equipment node exits the network, the cooking equipment node to exit needs to broadcast a third broadcast message carrying a network exit notification to other cooking equipment nodes in the block chain network to inform the other cooking equipment nodes of the operation of exiting the network, generating a new authentication type block in the block chain after the third broadcast message received by the other cooking appliance nodes, the authentication type block deletes the registration information of the cooking appliance node to be exited and stores all other registration information at the network node, therefore, each time whether the cooking device node is legal or not is checked, only the newly generated authentication type block (namely, the authentication type block located at the tail part of the data structure of the block chain) is called, and whether the corresponding registration information exists or not is searched from the latest authentication type block without backtracking to the previous authentication type block.
And S2, broadcasting a first broadcast message carrying signature identification information in the block chain network by the current cooking equipment node, so that other cooking equipment nodes in the block chain network verify the signature identification information by using pre-stored registration information corresponding to the current cooking equipment node, and if the signature identification information passes the verification, generating a verification type block in the block chain to record the cooking equipment parameter verification information of the current cooking equipment node.
Specifically, after receiving a first broadcast message broadcast by a current device node, other cooking device nodes in the block chain network verify signature information in the signature identification information by using a public key in registration information corresponding to the current device node prestored in an authentication type block of the block chain, where the signature information is signature information generated by the current cooking device node by using its own private key, and therefore only the corresponding public key passes verification. If the verification is passed, the current cooking equipment node can be confirmed to be legal, and the collected cooking equipment parameters are also legal, so that the first identifier in the signature identifier information and the public key corresponding to the current cooking equipment parameters are used for generating cooking equipment parameter verification information, a verification type block is generated in a block chain so as to record the cooking equipment parameter verification information of the current cooking equipment node, and subsequently, when the collected cooking equipment parameters are used, the cooking equipment parameters can be verified according to the cooking equipment parameter verification information to determine that the cooking equipment parameters are collected legally and are not tampered.
Referring to fig. 2, in some examples, after the S2 current cooking device node broadcasts the first broadcast message carrying the signature identification information in the blockchain network, further comprising:
and S3, storing the cooking equipment parameters into the database by the current cooking equipment node.
Specifically, the blockchain network is further connected to a database, and the database may be stored in the same server as the blockchain network or in a different server, which is not limited herein. The database is used for storing the cooking data parameters legally acquired by each cooking equipment node in the block chain network, and when the acquired cooking equipment parameters are checked or called, the cooking equipment parameters can be directly searched from the database index without being searched from the chain structure of the block chain, so that the calculation amount can be reduced. After the cooking equipment data is collected by the cooking equipment node every time, the cooking equipment data is verified in S1-S2, and if the verification is passed, the current cooking equipment node stores the cooking equipment parameters, the first identification corresponding to the cooking equipment parameters and the block height (namely the block number) of the verification type block generated by the record in the database.
In some examples, when the cooking appliance node uses the cooking appliance parameters in the database, the method further comprises:
and S4, verifying the cooking equipment parameters in the database by using the cooking equipment parameter verification information corresponding to the cooking equipment parameters in the block chain.
When the cooking equipment node needs to check or call a certain cooking equipment parameter stored in the database, the corresponding cooking equipment parameter in the block chain can be found out, and the cooking equipment parameter and the corresponding cooking equipment parameter are compared and checked to ensure that the data are collected by the legal cooking equipment node and are not tampered.
Specifically, with reference to fig. 2, in some examples, the S4, verifying the cooking device parameter by using the cooking device parameter verification information corresponding to the cooking device parameter in the block chain specifically includes:
and S41, generating a second identifier according to the preset algorithm according to the cooking equipment parameters in the database.
The cooking device node calls out the cooking device parameters in the database, and generates the second identifier according to a preset algorithm, where the preset algorithm may be a hash algorithm, such as the SHA-256 algorithm, or may be other hash algorithms, which is not limited herein. And hashing the cooking equipment parameters in the database according to a hashing algorithm to generate a second identifier, namely generating short characteristic character strings with fixed byte length for the cooking equipment parameters called at this time in the database, wherein the characteristic character strings are the second identifier and are also called the hashing identifier.
And S42, searching whether the first identifier identical to the second identifier exists in the block chain. If so, the check passes.
Specifically, the algorithms for forming the first identifier and the second identifier are the same, so that the check type block corresponding to the block height in the block chain can be searched according to the block height corresponding to the cooking equipment parameter corresponding to the second identifier, and then whether the first identifier with the same hash value of the second identifier exists in the check type block is searched, if so, the cooking equipment parameter corresponding to the second identifier is proved to be collected by a legal cooking equipment node, and the cooking equipment parameter is not modified because the first identifier is the same as the second identifier, so that the safety of the cooking equipment parameter can be ensured.

The sending device 012 is configured to broadcast a first broadcast message carrying signature identification information in the blockchain network, so that other cooking equipment nodes in the blockchain network verify the signature identification information by using pre-stored registration information corresponding to the current cooking equipment node, and if the verification passes, a verification type block is generated in the blockchain to record cooking equipment parameter verification information of the current cooking equipment node.
