Embodiment Construction

[0034] In order to describe the present invention more specifically, the technical solutions of the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0035] Such as figure 1 As shown, the blockchain digital education service platform calls the digital watermark service system to request watermark services for various resources in the digital resource library. After receiving digital resources, the watermarking system can automatically identify the type of the resource, call different watermarking algorithm libraries and add watermark information according to the type of resource, and then return the resource file with the digital watermark added to the caller (that is, blockchain digital education service platform).

[0036] The watermark system can automatically identify digital resource files and prevent malicious attacks at the same time. If file type checking is not performed, attackers are likel...

Abstract

The invention discloses an automatic watermark adding method for a block chain digital education platform, which comprises the following steps that: (1) the block chain digital education platform calls a digital watermark service system and requests a watermark service for any resource in a digital resource library; (2) the watermark system automatically identifies the type of the resource after receiving the digital resource; (3) different watermark algorithm libraries are called and watermark information is added according to the types of the digital resources; and (4) the resources added with the digital watermarks are added to the block chain digital education service platform. Based on this, for watermark interfaces of various carriers, a user only needs to adjust the service of the watermark system, and the watermark service system relies on the block chain platform to record relevant copyright information on the block chain, so that a guarantee is provided for the credibility of the digital watermark.

Description

technical field [0001] The invention relates to the field of copyright protection of digital resources in a blockchain digital education platform, in particular to an automatic watermarking method and system for a blockchain digital education platform. Background technique [0002] Today, with the increasing popularity of Internet technology, the creation and dissemination of digital resources in digital education is becoming more and more frequent. Due to the characteristics of strong dissemination and wide audience of digital resources, the issue of copyright disputes has gradually become the focus of public attention. The main reasons for the frequent occurrence of digital resource infringements are as follows: digital resources can be downloaded from many websites, which creates convenient conditions for piracy of digital resources; the cost of spreading pirated resources on the Internet is relatively low, which creates certain difficulties for copyright supervision . ...
