# NFT Technology for Enhanced Global Digital Registers: A Novel Approach to Tokenization
## 2 Literature Review
### Gaps in Current Research and Our Proposed Approach  
Despite the growing interest in blockchain technology and NFTs for digital asset management, there remain significant gaps in the current research, particularly in terms of addressing the limitations of existing centralized and decentralized systems, such as scalability, interoperability, and customizability. Existing global identification systems, such as ISBN (International Standard Book Number), ISSN (International Standard Serial Number), DOI (Digital Object Identifier), ASIN (Amazon Standard Identification Number), BICI (Book Item and Component Identifier), ISAN (International Standard Audiovisual Number), ISMN (International Standard Music Number), ISRC (International Standard Recording Code), ISTC (International Standard Text Code), ISWC (International Standard Musical Work Code), ISWN (International Standard Wine Number), and LCCN (Library of Congress Control Number), each serve specific industries and purposes. However, these systems face the following common challenges:  
1. Centralization: Most of these systems rely on centralized authorities, making them vulnerable to single points of failure and censorship;
2. Limited interoperability: Each system operates independently, with minimal cross-system integration capabilities;
3. Lack of real-time verification: Many of these systems do not offer instant, global verification of identifiers;
4. Inefficient rights management: Tracking and managing rights across different systems and jurisdictions is often complex and time-consuming;
5. Scalability issues: As the volume of digital content grows exponentially, traditional systems struggle to keep pace. The idea of using NFTs to tokenize these pre-existing global digital registries has not been explored in the reviewed literature, representing a significant gap in current research. Our proposed decentralized global registry system aims to fill these gaps by providing a secure, transparent, and efficient solution for tokenizing global digital registers and facilitating the creation of new registries for unique objects and content. By leveraging the potential of NFTs to represent unique identifiers for digital resources within a secure and transparent blockchain network, our approach offers a novel contribution to the field of digital asset management. Specifically, our research aims to address the following gaps:  
1. Unified tokenization framework: We propose a standardized approach to tokenize diverse types of identifiers (e.g., ISBN, ISRC, DOI) using NFTs, enabling cross-system interoperability;
2. Decentralized verification: Our system allows for real-time, global verification of identifiers without relying on centralized authorities;
3. Enhanced rights management: By leveraging smart contracts, we enable automated, transparent, and efficient management of rights across different types of content;Scalability solutions: We explore layer-2 scaling solutions and cross-chain interoperability to address the scalability challenges faced by both traditional systems and existing blockchain networks;
* Privacy-preserving transparency: Our research investigates the use of zero-knowledge proofs to balance the need for transparency with privacy requirements, a crucial aspect not addressed in current identification systems. The proposed system focuses on enhancing the security, authenticity, and traceability of these global digital registers, significantly mitigating the limitations of current systems and paving the way for the preservation and wider accessibility of unique, valuable digital resources. By applying our system to existing registries such as ISBN, ISSN, DOI, and others, we can provide enhanced security, censorship resistance, and decentralization, enabling seamless and transparent management of unique identifiers for books, periodicals, digital objects, and other content.
