Contratos Inteligentes para a Gestão Automatizada de Direitos Musicais

Abstract

A presente dissertação propõe o desenvolvimento de uma plataforma designada SoundSlice, que visa automatizar a gestão de direitos de autor em conteúdos musicais reutilizados e na criação de mixes, através da integração de tecnologias blockchain e contratos inteligentes. O sistema permite o registo de obras originais, reutilizações parciais, a combinação de múltiplas faixas em novas composições (mixes) e a atribuição automática de compensações aos titulares de direitos, assegurando transparência e rastreabilidade em todo o processo. A solução combina uma infraestrutura centralizada, suportada por uma base de dados MongoDB e armazenamento de ficheiros GridFS, com uma camada descentralizada baseada em Ethereum, responsável pela execução dos contratos inteligentes que formalizam a partilha de royalties. A nível prático, foi implementado um frontend web que permite o upload, análise, reutilização e criação de mixes musicais, bem como um backend Node.js que gere a lógica de negócio e a comunicação com a blockchain. O desenvolvimento da plataforma baseou-se nos conceitos teóricos e modelos de integração propostos pelos padrões Smart Contracts for Media (SC4M) e Interactive Music Application Format (IMAF), os quais orientaram a estruturação de metadados, a modelação de contratos e o desenho da arquitetura da plataforma. Por fim, foram conduzidos testes funcionais, de desempenho e de usabilidade que demonstraram o correto funcionamento da plataforma, a eficiência na execução de transações e a aceitação positiva por parte dos utilizadores, validando a viabilidade e o contributo da abordagem proposta.

This dissertation presents the design and development of the SoundSlice platform. It aims to automate copyright management of reused musical contents and mix creation through the integration of blockchain technology and smart contracts. The system enables the registration of original works, the partial reuse, the combination of multiple tracks into new compositions (mixes), and the automatic distribution of royalties to rights holders, ensuring transparency and traceability throughout the process. The solution combines a centralized infrastructure, supported by a MongoDB database and GridFS file storage, with a decentralized layer based on Ethereum, responsible for executing smart contracts that formalize royalty sharing. A web frontend was developed to support the upload, analysis, reuse, and creation of musical mixes, while a Node.js backend handles the business logic and communication with the blockchain. The platform’s design was guided by the theoretical foundations and integration principles of Smart Contracts for Media (SC4M) and Interactive Music Application Format (IMAF) frameworks, which informed the metadata structure, contract modeling, and overall system architecture. Finally, functional, performance, and usability tests were conducted, confirming the platform’s correct operation, transaction efficiency, and positive user perception, validating the feasibility and relevance of the proposed approach.
