Routing position data secrecy storing and sharing method based on block chain

Abstract

Provided is a routing position data secrecy storing and sharing method based on block chains. The routing position data secrecy storing and sharing method includes a data storing method and a data sharing method. The data storing method includes the steps of node configuration, data encryption sending, storage subnetwork verification storing, etc. The data sharing method includes the steps of demand generation, demand response, sharing achievement and the like. The effects of the invention are as follows: through a block chain technology, data sharing is realized through data encryption storage and a decentralized network to solve the problems that data storage parties have no right to use data and users do not have channels to selectively enable personal data to be accessed; local encryption sending is adopted during data storage, service parties store encrypted data, the users themselves save decryption secret keys, and the service parties have no access to original data, so a better data protection effect is achieved; and the block chain technology is adopted during storage, commonly recognized storage is realized through a practical Byzantine fault-tolerant algorithm, workload bottleneck problems of centralized storage are solved, and data is prevented from being tampered.

Description

technical field [0001] The invention relates to a method for securely storing and sharing routing location data based on a block chain, and belongs to the technical field of data Internet. Background technique [0002] Blockchain is a distributed data storage solution that provides a decentralized collective maintenance strategy through a peer-to-peer model. This technology summarizes system exchange data over a period of time, generates data blocks through modern cryptography, and uses timestamps to generate data fingerprints, connects data blocks into chains, and provides validity verification and auditing. [0003] There are two main methods of traditional routing location data storage and sharing: centralized storage and centralized sharing and distributed storage and centralized sharing. The working process of centralized storage and centralized sharing is: the server collects all user data and stores them centrally, and each sharing request must be sent to the server ...

AI Technical Summary

Problems solved by technology

The first method uses centralized storage, which is easy to maintain and has high security, but service bottlenecks are likely to occur due to the large workload; the second method uses distributed storage technology, but the sharing requirements are still processed by the central server. To find the required data through distributed storage increases the complexity of the system

In addition, although the data stored in the two methods have been encrypted, they can still be used freely as a service provider, and user privacy cannot be effectively guaranteed; the user's sharing needs are passed through the shared processing center. If you can't work, you can't share data
