Multimedia data access method based on multi-protocol convergence network

Abstract

The invention discloses a multimedia data access method based on a multi-protocol fusion network, aims at multimedia data such as videos, voices, files and pictures, combines the technical advantagesof a wireless broadband ad hoc network, a block chain and an IPFS network to realize safe access of the multimedia data, and belongs to the technical field of combination of wireless communication andthe block chain. According to the method, on the basis of a communication protocol of the wireless broadband ad hoc network, decentralization and data security characteristics of a blockchain and anIPFS protocol are fused, and a brand-new multi-protocol fusion network architecture is constructed, so that secure storage and reading of multimedia data in the wireless broadband ad hoc network are realized. A multi-protocol convergence network is created, the network is composed of a plurality of nodes, and each node comprises a wireless broadband ad hoc network layer, an IPFS network layer, a block chain network layer and a multi-network convergence gateway layer. The method is wide in application range, can be used in some places with extremely high safety requirements, and can effectivelyreduce the storage cost of multimedia data.

Description

technical field [0001] The invention relates to a multimedia data access method based on a multi-protocol fusion network, in particular to multimedia data such as video, voice, files and pictures, and belongs to the technical field of combining wireless communication and block chain. Background technique [0002] Wireless broadband ad hoc network is a wireless private network communication system currently used in public security, emergency and other industries. It can realize multi-hop, dynamically scalable wireless ad hoc network communication, and can form a star or mesh network structure arbitrarily. The transparent transmission of data between multi-point devices in the network has the characteristics of long communication distance, strong anti-interference ability, flexible networking, fast and convenient deployment, etc., and currently plays an important role in handling emergencies and security. However, in current industrial applications, the multimedia data collect...

Problems solved by technology

However, in current industrial applications, the multimedia data collected by the terminal equipment is sent back to the back-end storage server through the wireless self-organizing network for storage. This single-point storage mode will cause the loss or tampering of the stored data, especially for The storage of sensitive data lacks security, and the authenticity of sensitive data itself cannot be ensured

Even if multiple backup storage methods are used, the authenticity of backup data cannot be guaranteed, and multiple backup storage methods require a large amount of storage costs
