Grain information management method and system

Abstract

The invention relates to a grain information management method, and the method comprises the steps that a mobile terminal builds safe cup-joint layer safety connection with a credible time stamp through a user digital certificate when a grain information submitting request is received; the mobile terminal carries out the call of the credible time stamp through the safe cup-joint layer safety connection, so as to generate credible time stamp information for the grain information; the mobile terminal builds safe cup-joint layer safety connection with a grain background server through the user digital certificate; and the mobile terminal enables the credible time stamp information and the grain information to be transmitted and stored in the grain background server through the safe cup-joint layer safety connection. The invention also provides a grain information management system. The method and system can provide reliable basis for the tracking of the quality safety of grains.

Description

technical field [0001] The invention relates to an information management method and system, in particular to a grain information management method and system. Background technique [0002] With the improvement of people's living standards, the requirements for food quality and safety are also increasing. In order to ensure the quality and safety of food, a quality and safety traceability system is usually established for food. The quality and safety traceability system refers to the standardized collection and storage of grain information that may affect grain quality and safety in various links such as grain purchase, storage, processing, and circulation, such as humidity, temperature, processing technology, and operators. , a quality and safety information management and traceability system released in various ways. Through the food quality and safety traceability system, the information reflecting the food quality and safety in the whole food supply chain can be effect...

Problems solved by technology

However, there are some data security issues in the wireless data communication between the mobile terminal and the grain background server at present, and it is impossible to guarantee that the uploaded data will not be tampered with

First of all, the external interface of the grain back-end server is basically based on HTTP (HyperTextTransferProtocol, hypertext transfer protocol) and seldom uses encryption and signature algorithms, which makes the security of the entire communication link in the process of grain information transmission low, so it cannot be guaranteed Food information is not intercepted or stolen

Secondly, the identity verification of the operator who inputs the grain information is neglected, which may easily cause illegal personnel to pretend to be the operator to operate or modify the source grain information

[0004] In addition, when the mobile terminal uploads grain information to the grain background server, it needs to record the upload time, but currently the current system time of the mobile terminal is usually used as the upload time, which may have a large time error and cannot be used as credible electronic evidence. Provide basis for information audit, security inspection and information traceability
