Mobile terminal position track monitoring system and method based on block chain

Abstract

The invention particularly relates to a mobile terminal position track monitoring system and method based on a block chain. The mobile terminal position track monitoring system based on a block chaincomprises a write-in/query operation judgment module, an MD5 encryption module, a MongoDB index recording module, a block chain storage module, an intelligent contract module, a position track drawingmodule and a position track prediction module, wherein the write-in/query operation judgment module is connected to the block chain storage module through the MD5 encryption module and the MongoDB index recording module in sequence, and the block chain storage module is connected to the position track drawing module and the position track prediction module through the intelligent contract module.The method has the advantages that the LAC/CI data generated when the user uses the communication service is accessed based on the block chain technology, the key information such as the number of the mobile terminal of the user is encrypted by combining the MD5 message digest algorithm, and the user position track monitoring efficiency is improved on the premise that the privacy of the user datais effectively guaranteed.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain-based mobile terminal position track monitoring system and method. Background technique [0002] Blockchain technology uses block chain data structure to verify and store data, uses distributed node consensus algorithm to generate and update data, uses cryptography to ensure the security of data transmission and access, and uses intelligent A new distributed infrastructure and computing method that uses contracts to program and manipulate data. At present, blockchain has been widely used in the financial industry, and various virtual currencies are especially represented by Bitcoin; in addition to being used in the financial industry, other industries such as logistics and real estate also have good applications prospect. [0003] At present, when a user uses an operator's communication service, the LAC (Location Area Code) and CI data (Cell Identification) i...

Problems solved by technology

However, in the existing technology, it is difficult to guarantee the information security of location information. If the historical location data leaks, it will pose a great threat to user security.

Moreover, when historical location information is lost or leaked, it will be impossible to predict the user's location trajectory based on historical data and simple algorithms
