Save the general method for anti-counterfeit of tracing to the source of agricultural product of technology based on electronic data from damage, comprising:
One, make and upload agricultural product and trace to the source information to agricultural product traceability anti-fake system platform;
(1) making of agricultural product production information.Before plantation, system sets up production base numbering, and system produces different RFID according to the numbering of different production base.Electronic tag after typing manufacturer information, production base information, fertilising dispenser information and information of gathering, is fixed in Turnover Box by the producer in rfid card; Finally product is loaded Turnover Box.
(2) making of Agricultural product ID information.Agricultural product to be certified are delivered Quality certification of agricultural products supervisory organ and are carried out detection certification by the producer, according to detection authentication result, the certification such as typing Pesticides Testing information, Organic certification information, international export qualification information in rfid card, and by during network implementation, related data is passed in system platform.
(3) making of processing of farm products information.Accept Turnover Box from production run after, process unit is sampling Detection product first, if Product checking is defective, then refusal accepts agricultural product.If it is qualified to detect, can processing link be entered, then read the RFID label tag of Turnover Box, by tag number stored in system, for the Turnover Box conversion of processing the later stage is prepared.Generate processing archives, processor's information of record current production, work flow information, and add cleaning in man-hour, the information such as chemical substance title, concentration, brand, supplier and packaging that waxing process uses.Then the product that dispatches from the factory is detected after machining, if it is qualified to detect, then by machining information and Detection Information stored in processing base database, and by during network implementation, related data is passed in system platform, the RFID label tag number of Turnover Box and the packing of product is bound simultaneously, enter storage and Logistics Process.
(4) making of agricultural products storage information.Similar with processing link, after entering storage link, via testing staff detect qualified after, read the RFID numbering in the packing of product, generate storage archives, record corresponding storage warehouse title, temperature, address and deposit warehouse compartment, when receiving order outbound, by the Shipping Information on issue voucher, prepare goods, when goods transports doorway, warehouse, directly read merchandise news and the quantity of transport outbound by electronic label read-write antenna, confirm consistent with issue voucher after, direct entrucking enters logistics link.The information such as the delivery of RFID record odd numbers, place of delivery etc. that issue voucher configures.Related data passes in system platform by during network implementation after making by storage information.
(5) making of agricultural product logistics information.In logistics link, first read issue voucher numbering, information such as record logistics start time and logistics vehicles etc.Logistics vehicles GP configuring S/GPRS realizes the real-time follow-up to logistics progress, and the routing information of registration of vehicle transport, configures temperature variations in temperature sensor record logistics progress, upload in system platform server in real time in vehicle-mounted freezer; After arriving dispensing destination, read issue voucher electronic labeling information by read write line, obtain invoice information content, read the goods of respective numbers and kind on car again, through freight detection, by network input issue voucher electronic tag coding after qualified, beam back system server, confirm that goods receives.
(6) in sales section, supermarket or retail point retail clerk pass through the merchant information of handheld device or computing machine typing oneself in rfid card, such as place, point of sale, trade company everyone, business licence plate are encoded, are sold mouth phase and source of goods channel information etc., and be uploaded to traceability anti-fake system platform in real time.
Two, agricultural product traceability anti-fake system platform receives agricultural product and to trace to the source information, calculates the cryptographic hash of information of tracing to the source and this cryptographic hash is pushed to time-stamping service center, completing the information of tracing to the source and save from damage;
After electronic labeling information chain generates, form the information of tracing to the source that agricultural product are complete.Electronic labeling information chain information is sent to two-dimension code generator by system automatically in the lump, and businessman connects Quick Response Code printing device and printable two-dimension code label.In order to ensure the authenticity of the information of tracing to the source, while information traced to the source by the complete agricultural product of final formation, agricultural product quality and safety traceability system data center server carries out Hash operation to the agricultural product information of tracing to the source and generates corresponding cryptographic hash uplink time stamp service centre, obtain the timestamp certificate of the information of tracing to the source corresponding to electronic labeling information chain, complete saving from damage of the information of tracing to the source.
Three, agricultural product are traced to the source false proof inquiry: consumer is by using inquiring client terminal, the information of tracing to the source of agricultural product can be inquired by mobile network after barcode scanning Quick Response Code, and the details of links, consumer can also be complained to supervision department by the information feed back menu of client simultaneously, and result can be fed back to consumer by supervision department after treatment timely
Four, to trace to the source information truth integrity verification.When there is agricultural product quality liability accident, after finding out culprit, need the legal liabilities investigating corresponding responsibility main body.Therefore need proof information of tracing to the source to arrive afterwards when agricultural product quality liability accident occurs in generation not distort, with clearly defining responsibilities people.At this moment inquire about these agricultural product by problem agricultural product electronic tag number to trace to the source information, then calculate these agricultural product and to trace to the source the cryptographic hash of information, and the cryptographic hash recorded in the timestamp certificate obtained when saving from damage with the information of tracing to the source is compared; If cryptographic hash is consistent, then prove that information of tracing to the source arrives when agricultural product quality liability accident occurs afterwards in generation not distort, person liable can be determined, if inconsistent, then prove that information of tracing to the source arrives when agricultural product quality liability accident occurs afterwards in generation to distort, person liable can not be determined according to the information of tracing to the source, need to determine person liable by other means.
The present invention's precision of tracing to the source is high, and the agricultural product produced using the different croplands of same production base are as object of tracing to the source; Scope of tracing to the source is wide, contain the links of agricultural product from field to the tip of the tongue, the agricultural product that consumer can record in inquiry system platform, from producing, detecting, process, store in a warehouse to the information of all links such as logistics, also can find out defective product scope and responsible party rapidly and accurately when agricultural product go wrong; The advantage of Appropriate application RFID and bar codes technique, saves great amount of cost; In links, utilize RFID simultaneously, reduce manually-operated error, improve work efficiency; Utilize electronic data to save technology from damage, verifying of information truth integrality of guaranteeing to trace to the source, be convenient to confirm agricultural product quality liability accident main body.
