Event audio and video trusted storage and sharing method and system based on block chain

Abstract

The invention belongs to the technical field of block chains, and particularly relates to a block chain-based event audio and video trusted storage and sharing system and method, the system comprises a hardware layer and a software layer, and the hardware layer is a block chain software and hardware all-in-one machine with a built-in block chain security chip; the software layer comprises a block chain network, a trusted object storage service and an audio and video trusted sharing network. By using a trusted object storage service, the storage security and high availability of an event audio and video original file are protected, a node service network based on a block chain is used, the hash of the event audio and video file is protected from being tampered, and the security and reliability of sharing of the event audio and video among multiple departments and multiple levels are protected by using the tampering-free characteristic of the block chain. The collaboration efficiency is enhanced, and the audio and video data credibility is enhanced by using the public, transparent and traceable characteristics of the block chain.

Description

technical field [0001] The invention belongs to the technical field of block chains, and in particular relates to a method and system for trusted storage and sharing of event audio and video based on block chains. Background technique [0002] A large amount of audio and video data will be generated in the event processing process, including the audio and video data collected by the staff of various departments during the event processing process and the audio and video data provided by the parties involved in the event as evidence. Event audio and video data, as important auxiliary data of event files, plays an irreplaceable role in event processing. Event audio and video sharing is a process in which each department records and archives the entire process of processing work through audio and video equipment during event processing, and transfers and shares the generated event audio and video data among other departments. At present, in terms of event audio and video stora...

AI Technical Summary

Problems solved by technology

[0004] The existing event audio and video storage method lacks sufficient technical guarantee in terms of reliability, security, and tamper-proof; in terms of sharing, the existing method cannot establish a normalized mechanism for event audio and video sharing among multiple departments, and the sharing efficiency is low , information asymmetry, business opacity, and difficulty in real-time verification, resulting in repeated confirmation and back-and-forth business communication between multiple departments, making collaboration difficult

The inventor of the present application found through actual research that there are still the following problems in the process of event audio and video storage and sharing in the prior art: the event audio and video are destroyed due to malicious attacks or malicious operations by insiders during the event audio and video storage process , tampering issues; inconvenient transmission of physical media in the event audio and video sharing process; information asymmetry and business opacity caused by system isolation in the event audio and video sharing process; malicious attacks or malicious insiders in the event audio and video sharing process The audio and video of the event caused by the operation is destroyed and tampered with
