Description
Technical field
A kind of encrypting the present invention relates to Product quality and safety technical field more particularly to based on block chain anti-tamper product
Quality safety traceability system and method.
Background technique
The quality safety of product is always most to make us the problem of paying attention to, either food or other devices in people's life
Tool only meets country, the qualified products of professional standard can just bring consumer best experience.
During the production of product, transport and sale, some criminals make product to reap staggering profits
Vacation has upset normal economic order so that the quality problems of product are increasingly severe, is unfavorable for consumer to authenticity of products
Identification so that consumer as product quality problems and product required for the use that cannot trust, be unfavorable for consumer's
Equity is effectively guaranteed；
Instantly in society, with the continuous development of e-commerce platform, more and more transaction are transferred to gradually under line
On internet, so that consumer is originally just not counting simply right-safeguarding mode becomes more difficult: on from production firm to line
Any one of during which business platform is finally transported in client's hand to logistics again, and entire process of transporting is longer, and link is likely to out
Existing product quality problem, and be difficult to quickly determine responsible party and rectification point after going wrong, cause the equity of consumer that can not reach
To guarantee.
Summary of the invention
It goes wrong thing the purpose of the present invention is to solve product quality in the prior art, can not quickly determine responsible party
And the problem of rectification point, and a kind of of proposition encrypts anti-tamper Product quality and safety traceability system and method based on block chain.
To achieve the goals above, present invention employs following technical solutions: it is a kind of encrypted based on block chain it is anti-tamper
Product quality and safety traceability system, including protection system, product registered terminal are connected with product safety retrospect server, the production
Product registered terminal is connect with product safety retrospect server, for sending the various of product to product safety retrospect server
Data；
The product registered terminal includes communication module, and the production and processing acquisition mould being electrically connected with the communication module
Block, logistics distribution acquisition module and product sell acquisition module, and the communication module and product safety retrospect server connect
It connects；
The production and processing acquisition module, for acquiring the information for producing and processing different nodes, and by the information by leading to
Letter module is transmitted to product safety retrospect server；The logistics distribution acquisition module, for acquiring logistics distribution difference node
Information, and by the information by communication module be transmitted to product safety trace server；The product sells acquisition module, uses
The information of different nodes is sold in acquisition product, and the information is transmitted to product safety by communication module and traces server；
Detection terminal is configured to send detection terminal public key to verifying terminal and the identity for verifying the operator
Operator message；Inspection is sent by verifying terminal public key when verifying terminal is configured to the identity of the operator described in good authentication
Terminal is surveyed, and will test terminal public key and verify terminal secret key and be sent to reception terminal；Detection terminal is configured to that institute will be utilized
The storage information for stating verifying terminal public key, the detection terminal secret key and fixed storage private key encryption is sent to reception terminal,
The storage information includes the identity of the operator, timestamp and is felt by multiple sensors that the detection terminal is included
The product parameters of survey；
Reception terminal is configured with fixed storage public key, verifying terminal secret key and detection terminal public key and decrypts the storage
Information simultaneously sends the notice for saving and completing to verifying terminal saving the rear of the storage information；
Terminal is verified to be configured to after receiving the notice for saving and completing by believing current authentication terminal secret key with random
The combination of breath iteration in hash function is greater than primary mode to update verifying terminal secret key.
It is encrypted in anti-tamper Product quality and safety traceability system and method above-mentioned based on block chain, the sensing
Product quality parameters include time, humidity, performance and GPS location.
It is encrypted in anti-tamper Product quality and safety traceability system and method above-mentioned based on block chain, the operator
Information includes user name, password and biological information and the biological information includes in fingerprint, facial characteristics and sound characteristic
It is a kind of.
It is encrypted in anti-tamper Product quality and safety traceability system and method above-mentioned based on block chain, the product peace
Full retrospect server has been directly connected to consumer and has checked terminal, and it includes the shifting with built-in camera that the consumer, which checks terminal,
Dynamic terminal, computer or self-help inquiry apparatus configured with camera.
It is encrypted in anti-tamper Product quality and safety traceability system and method above-mentioned based on block chain, the consumer
Checking terminal includes examination module and alarm module, and the alarm module is electrically connected with the examination module, in the examination
Module checks in when the product is fake products and issues alarm signal.
