Embodiment Construction

[0039] The present invention will be specifically introduced below in conjunction with the accompanying drawings and specific embodiments.

[0040] The present application is based on the system framework described below to facilitate secure distributed sharing and storage to detect copyright infringement of multimedia objects. It consists of the following three distinct modules:

[0041] Image and video upload layer: This module is responsible for uploading various images and videos and their details of photographers, video providers and graphic designers. By sharing these images and videos, you can get due credits for their work.

[0042] Secure Distributed Storage Layer: This module is responsible for secure storage of multimedia objects and creating addressable hashes of uploaded objects. IPFS provides the facility to synchronize these videos and images to the corresponding peers. The underlying method uses distributed hash table-based address storage and version control...

Abstract

The invention discloses an image file sharing platform infringement protection method based on a block chain and an IPFS. The method comprises the following steps: receiving an uploaded new image file; calculating the pH (Potential of Hydrogen) ash of the new image file; judging whether the uploaded new image file meets the standard or not according to the calculated pH ash; adding the new image file meeting the standard to an IPFS network; and updating the block chain network, and adding the pHash of the new image file into the block chain network. According to the image file sharing platform infringement protection method based on the block chain and the IPFS, a perceptual hash algorithm is adopted, the perceptual hash algorithm is different from password hash such as MD5, and the perceptual hash algorithm has similar output for input with similar characteristics. Therefore, the user can be effectively prevented from infringing the copyright by simply modifying the video, and the intellectual property of the creator can be well protected without manual auditing.

Description

technical field [0001] The present invention relates to a copyright protection method of an image file sharing platform, in particular to a copyright protection method of an image file sharing platform based on blockchain and IPFS. Background technique [0002] The InterPlanetary File System (IPFS) is a network transmission protocol for storing and sharing data through a peer-to-peer network in a distributed file system. IPFS can use a distributed web gateway to access the file system simply, quickly and securely without a local node. From the beginning of its design, IPFS can avoid large-scale downtime and data loss of centralized servers, and is especially suitable for the transmission of high concurrency, large files, and real-time media streams in the era of big data. When the nodes joining IPFS reach a certain scale, the distributed Web will become the fastest, most reliable, and largest data warehouse in the world. [0003] Blockchain has shown broad application pros...
