Referring to fig. 2-3, the method for tracing a biotech product includes:
step S10: acquiring initial seed character information, and generating first coding information according to the character information according to a preset rule; transferring the initial seeds, acquiring character information of the transferred seeds, and generating second coding information for the transferred seeds according to the preset rule; and performing propagation on the transformed seeds, acquiring property information of the propagated seeds, and generating third coding information on the propagated seeds according to a preset rule.
The first coding information, the second coding information and the third coding information are necessary information from the research and development of the seeds to the production stage, and the accuracy and the safety of information recording at the stage have influence on the retroactive relevant keys of the whole seed product at the later stage.
Step S20: the first coding information, the second coding information and the third coding information sequentially form a character parent relation, and the first coding information, the second coding information and the third coding information form a chain type time stamp.
In the embodiment of the application, the first coding information, the second coding information and the third coding information form a chain timestamp, so that a tracing process of a product can be formed. Further, the specific process of forming the first coding information, the second coding information and the third coding information into the chained timestamp may refer to the following steps:
step S21, the distributed network includes at least one supervising node, through which the nodes are connected to the logging nodes and which performs the operations associated with the logging node query procedure.
In some embodiments, the entry node may transmit the data to be verified over the distributed network by issuing a publish-subscribe pattern, which may include any data or information to be verified that is transmitted from one entry node to another node on the network, and the verification information may be altered or otherwise changed. In addition, the information to be verified may also be self-executing at the respective node the corresponding network protocol in the form of computer programming code/instructions, which may be managed by the protocol stored on the distributed network. When a preset condition is reached, the corresponding network protocol may be automatically executed.
Wherein the supervising node performs final verification on the inquiry process, and the verification result is an entry node verification result subset. By the method, the accuracy and the anti-tampering characteristic of the recorded information of the seed product in the tracing process can be enhanced.
Step S22: and inquiring historical input information of the last time point according to the unique identifier, comparing the newly input information with the historical input information, storing the historical input information in a plurality of nodes of the distributed network, recording the information input information after the newly input information is successfully compared with the historical input information in each node, generating a chained timestamp, and sending the input information to a supervision node.
In some embodiments, the logging information may be information recorded in the above-mentioned encoded information. The entry information may include unique information, attributes or characteristics of its seed. The logging information may include attestation information or non-tamperable metadata describing or defining its authenticity and is transmitted between nodes of the distributed network. Further, the entry information is inseparable and not mutually interchangeable.
And when the newly input information is successfully compared with the historical input information in each node, recording the information input information, generating a chain type timestamp, and sending the input information to the supervision node.
In some embodiments, the logging information may be distributed via a distributed network protocol, the distributed network may be configured to allow the logging node to determine to send the security verification information, and the protocol used may be configured to provide options for use of distributed network security verification, and the distributed network security verification techniques may include encryption, scrambling, embedding tags, and the like.
Step S23: each piece of coded information contains seed character information, the seed character information generates a preset character identifier through a preset encryption rule, and the character identifier is associated with the unique identifier. The formed coding information can be subjected to reverse tracing according to the chain type timestamp, and a new coding information is formed in the reverse tracing process and a tracing process timestamp is generated.
In certain embodiments, seed trait information is also added to the seed coding information and a preset trait information identifier is generated, wherein the trait identifier is associated with the unique identifier. The logging node can generate a random label for the trait identifier and send the random label to the downstream node to associate the unique identifier so as to provide a proof of correctness of the logging information of the downstream node, and the distributed network further divides the encrypted information by a network protocol and associates the encrypted information with different associated nodes in a preset ratio. When the entry node is specific authentication data, the entry node may determine the preset partition ratio such that a given percentage is applied to the entry node during the session based on the password, and the remaining percentage is applied to the corresponding upstream relay node. In this way, the distributed network may be used to split the verification among the nodes of different functions on the distributed network.
Step S30: storing the uploaded seed coding information through a distributed network, and generating a unique identifier of the seed coding information according to a preset encryption rule; and when new information is recorded into the seed coding information, performing cross validation on the seed coding information stored last time, wherein the cross validation is realized through distributed network nodes.
In some embodiments, the entry node may query whether the entry node actually holds a key. The logging node may generate a random label and send the random label to the downstream node for signing in order to provide proof of the address of the downstream node. The random tag may comprise a random or pseudo-random number issued in an authentication protocol for the above mentioned verification purposes. The entry node may query the distributed network by an address obtained from a downstream node to determine the accuracy and tamper resistance of the entered information.
Further, the information node to be authenticated or the logging node may be configured to generate an encrypted data stream and a corresponding data encryption key. The logging node only shares the encrypted stream and the encryption key with the authorizing node. For the transmission of the verification information, the entry node may generate a data stream and generate a corresponding seed; furthermore, the network may derive a symmetric key from the seed, and the supervising point may send the symmetric key to the entry nodes when the entry nodes communicate with the decentralized entry nodes. When the entry node with the corresponding information to be verified meets the conditions, the entry node can receive encrypted data from the entry node through the encrypted channel. Asymmetric encryption keys may also be used, and the network may use two different types of keys for validating key pairs and for encrypting and decrypting data streams between nodes.
Step S40: the later formed coding information can be reversely traced according to the chained timestamp, the reverse tracing process forms new coding information and generates a tracing process timestamp
In some embodiments, the biotech product tracing method of the application may further set the coding information of the reverse tracing process in the tracing process, where the coding information may record query information in the tracing process, so as to further increase the integrity of information in the whole product tracing process, where the timestamp of the tracing process may be individual timestamp data.
