# NFT Technology for Enhanced Global Digital Registers: A Novel Approach to Tokenization
## 2 Literature Review
### Existing Global Digital Registries and Their Limitations  
IBM's Asset Repository (AR) is a prominent industrial global registry system [16]. It aims to centralize asset management by integrating asset information from multiple sources, but its reliance on traditional database structures limits its scalability and flexibility. Moreover, it lacks a specific focus on intellectual property rights management and does not readily adapt to new asset types or changing business needs.  
Microsoft's Digital Asset Management (DAM) system [17], another notable industrial solution, provides a centralized platform for managing digital assets. However, it has similar limitations in scalability and flexibility due to its reliance on conventional database architectures. Furthermore, it does not offer a comprehensive solution for managing intellectual property rights, nor does it easily adapt to diverse systems and technologies.  
Several other leading IT companies, such as Oracle [18; 19], Alfresco [20; 21; 22], Adobe [23; 24], and SAP [25; 26; 27], have developed digital asset registries to address various challenges in managing digital assets. However, these systems exhibit shortcomings in scalability, flexibility, interoperability, and comprehensive intellectual property rights management.  
The patent by [PERSON] et al. [28] describes a central asset registry for media asset management, which integrates multiple repositories and tracks relationships between assets. While this solution offers improved speed, scalability, and flexibility in handling media assets, it does not specifically address the issues of intellectual property rights management or the verification of the authenticity of the assets.  
The patents by [PERSON] et al. [29; 30] present a central asset registry system for managing media assets and their intellectual property rights. While the solution helps address the challenges of asset navigation, storage, and retrieval, it may not be as comprehensive in handling intellectual property rights as our solution, which is specifically designed for IP rights management and protection.  
In addition to the previously discussed patents, several other patents have been reviewed to provide a comprehensive understanding of the current landscape in digital asset management. The patent by [PERSON] and [PERSON] [31] focuses on an e-commerce system that allows recipients to request the crowdfunding of items as gifts, with contributors purchasing parts of the item(s). While this concept addresses a specific niche in the retail industry, it does not explore the broader applications of NFTs and the tokenization of unique digital assets. The patent by [PERSON] [32] details an origin tag with a unique identifier for providing traceability of objects or animals throughout various handling steps, targeting specific needs in industries such as livestock and forestry. However, it does not encompass the wider scope of our NFT-based solution for global digital registers. The patent by [PERSON] [33] focuses on using artificial intelligence to identify and search for subjects or objects, particularly vehicles, while building provenance and preserving knowledge about their cultural history. However, this approach lacks the advantages of our blockchain-based solution, which ensures the highest level of transparency, security, and immutability for provenance tracking. Finally, the patents by [PERSON] [34; 35] discuss a framework for accelerating development on decentralized networks by reusing existing logic and focusing on creating new desired behaviors. While it aims to simplify the development process, it does not specifically address provenance tracking and data integrity, which are critical aspects of our solution.
