An Intellectual Property Protection Platform Based on Blockchain Technology

In order to solve the problems in the traditional field of intellectual property protection, such as difficulty in property rights confirmation, infringement monitoring, and evidence collection, The paper proposes an intellectual property protection platform based on blockchain technology, mainly introducing the overall architecture design, implementation goals, and the main characteristics of the proposed framework; According to practical application requirements, the framework modules are divided into three main modules: user digital content upload, secure distributed storage, and digital content infringement detection. The content involved in each module is explained; Introduced the copyright infringement detection process for digital content and provided a specific description of the steps involved. By building relevant experimental environments and deploying blockchain and IPFS platforms, a prototype system for digital copyright certification and access control was developed. The experimental results indicate that semantic factors were considered and incorporated into the text, with TF-IDF weights adjusted based on multiple features of words (word length, part of speech, occurrence position, and topic relevance), resulting in a 0.145 increase in F1 mean and an overall 0.425 improvement compared to the original SimHash algorithm. This paper improves the traditional SimHash algorithm by only considering the single feature of words in word weight calculation, selecting keywords with the top 50% weight values to generate text fingerprints, and then comparing the similarity between texts through Hamming distance. Additionally, the final experimental results also prove the effectiveness of this method.
