In addition, the present application provides examples of various specific processes and materials, but one of ordinary skill in the art will recognize the application of other processes and/or the use of other materials.
Referring to fig. 1, a process of tracing a biotechnological product back across an industrial chain according to an embodiment of the application is shown. Although various tracing systems exist in the market at present, the existing tracing systems usually trace each link in a main body or trace production and sales links located downstream in an industrial chain. The industrial chain related to the industrialization of the biotechnology products is long, the related links are more, and the links on the upstream and downstream are not participated by the same main body under many conditions, so that the existing traceability system cannot be suitable for the traceability of the biotechnology products.
As a method provided by the embodiment of the application, seeds are used as the traceable objects, and the main body of each link is responsible for uploading the information of the seed batch to the system and associating the information of the link. When seeds are transferred between upstream and downstream main bodies, a unique code is required to be given to the batch of seeds, after seeds provided by the upstream main bodies are bred by the downstream main bodies, the obtained seeds are given a new code, the downstream main bodies can add information related to the link by themselves when associated with the information, but the information related to the upstream ring can only be obtained through the codes of the seeds provided by the upstream main bodies, and cannot be added to a system by the downstream main bodies by themselves. And the seed codes of all links are associated, so that the data and information of the whole flow are collected.
For a biotechnological trait developer, unique coding information (C1) of the seed A is generated by the seed of the transformant A, wherein the added information may include developer information, seed lot, transformant name, security certificate information, date of delivery, and the like. When seeds flow into a variety cultivating body, the cultivating body can backcross the transformant A to obtain seeds X (A) of an X strain, and when the X (A) is delivered to a downstream body, a unique code (C2) is generated, upstream information is obtained by correlating the code (C2) with the code (C1), and the information which can be added at this stage comprises variety cultivating person information, seed batch information, variety names, parent names, variety approval information, warehouse date information and the like. When the seeds further flow into a seed producer main body, the seed producer main body can conduct propagation cultivation aiming at the seeds, specifically, X (A) is used as a parent seed production to obtain XY (A), the XY (A) seeds are processed to obtain commercial seed products, further, the seeds X (A) are propagated to obtain seeds X (A) for seed production, the X (A) is hybridized to obtain XY (A), commercial seeds XY (A) are obtained through processing, unique codes (C3) are generated, and upstream information of the seeds is obtained through correlating the codes (C3) with the codes (C2). The stage adding information can comprise information such as propagation batch of X (A) seeds, XY (A) production and processing batch, minimum sales unit specification, minimum sales unit area, warehouse date and the like. Further, when the seeds sequentially flow into the distributor, the retailer and the farmer, the unique code information (C4) and the unique code information (C5) can be sequentially produced, wherein the code information (C4) mainly comprises distributor information, warehouse-in date information and warehouse-out date information, the code information (C5) can comprise retailer information, warehouse-in date information, sales date information and the like, and the upstream information can be obtained by associating the code information with the code information of the previous stage, which is not described herein again.
Referring to fig. 2-3, the method for tracing the biotechnological product includes:
step S10: acquiring initial seed property information, and generating first coding information according to a preset rule by the property information; transferring the initial seeds, acquiring character information of a transfer seed, and generating second coding information by the transfer seed according to the preset rule; and propagating the transgenic seed, acquiring the character information of the propagated seed, and generating third coding information by the propagated seed according to a preset rule.
The first coding information, the second coding information and the third coding information are necessary information of the seed research and development to the production stage, and the accuracy and the safety of information recording at the stage have key influence on the tracing of the whole seed product at the later stage.
Step S20: the first coding information, the second coding information and the third coding information form a character parent relation in sequence, and the first coding information, the second coding information and the third coding information form a chain type timestamp.
In the embodiment of the application, the first code information, the second code information and the third code information form a chain type timestamp, and a tracing process of product completion can be formed. Further, for a specific process of forming the chain timestamp from the first encoded information, the second encoded information and the third encoded information, reference may be made to the following steps:
step S21 the distributed network comprises at least one supervising node, connected to the logging node by the supervising node, and the supervising node performs operations associated with the logging node query procedure.
In some embodiments, the logging nodes may transmit data to be authenticated through the distributed network by issuing a publish-subscribe pattern, which may include any data or information to be authenticated transmitted from one logging node to another node on the network, and may alter or otherwise change the authentication information. The information to be verified can also self-execute the corresponding network protocol in the form of computer programming code/instructions at the respective nodes, which instructions can be managed by the protocol stored on the distributed network. When the preset condition is reached, the corresponding network protocol may be automatically executed.
The supervising node performs final verification on the query process, and the verification result is a subset of input node verification results. By the method, the accuracy and tamper-proof property of the seed product in the process of tracing the information can be enhanced.
Step S22: inquiring the history input information of the last time point according to the unique identifier, comparing the newly input information with the history input information, storing the history input information in a plurality of nodes of a distributed network, recording the information input information after the newly input information is completely compared with the history input information in each node successfully, generating a chain type time stamp, and sending the input information to a supervision node.
In some embodiments, the entered information may be information recorded in the encoded information described above. The entered information may include unique information, attributes or features of its seed. The entry information may include attestation information describing or defining its authenticity or non-tamperable metadata and is transmitted between nodes of the distributed network. Further, the entered information is not separable and not interchangeable.
And after the newly recorded recording information is successfully compared with the history recording information in each node, recording the information recording information, generating a chain type timestamp, and sending the recorded information to the supervision node.
In some embodiments, the entry information may be distributed through a distributed network protocol, which may be configured to allow the entry node to determine to send security verification information, and the protocol used may be configured to provide options for use in distributed network security verification, and distributed network security verification techniques may include encryption, scrambling, embedding tags, and the like.
Step S23: each piece of encoded information comprises seed property information, the seed property information generates a preset property identifier through a preset encryption rule, and the property identifier is associated with the unique identifier. The formed coded information can be traced reversely according to the chained time stamp, the tracing process forms new coded information and generates a tracing process time stamp.
In some embodiments, seed trait information is also added to the seed encoding information and a preset trait information identifier is generated, wherein the trait identifier is associated with the unique identifier. The entry node may generate a random tag for the trait identifier and send the random tag to the downstream node to associate the unique identifier so as to provide proof of correctness of the downstream node in correspondence of the entry information, and the distributed network may further segment the encrypted information by a network protocol and associate to associated nodes of a preset ratio and different. When the logging node is a particular authentication data, the logging node may determine a preset split ratio such that a given percentage is applied to the logging node during the session based on the password, while the remaining percentages are applied to the respective upstream relay nodes. In this way, the distributed network may be used to segment verification among 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; when new information is recorded into the seed coding information, the seed coding information stored last time is subjected to cross verification, and the cross verification is realized through distributed network nodes.
In some embodiments, the logging node may query whether the logging node actually holds a key. The logging node may generate a random tag and send the random tag to the downstream node for signing in order to provide proof of the address of the downstream node. The random tag may include a random or pseudo-random number issued in an authentication protocol for verification purposes as described above. The logging node may query the distributed network by means of an address obtained from a downstream node to determine the accuracy and tamper resistance of the logging 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 entry node shares the encrypted stream and encryption key only with the authorization node. For verification information transmission, the logging node may generate a data stream and generate a corresponding seed; furthermore, the network may derive the symmetric key from the seed, and the supervising point may send the symmetric key to the logging nodes when the logging nodes communicate with the decentralized logging nodes. When the input node with the corresponding information to be verified meets the condition, the input node can receive encrypted data from the input node through an encrypted channel. The application may also use asymmetric encryption keys 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 formed coded information can be reversely traced according to the chain type time stamp, the reverse tracing process forms new coded information, and a tracing process time stamp is generated
In some embodiments, the biotechnological product tracing method of the present application may further set the encoded information of the reverse tracing process in the tracing process itself, where the encoded information may record the query information in the tracing process, so as to further increase the integrity of the information in the whole product tracing process, where the timestamp of the tracing process may be separate timestamp data.
