摘要
企业大数据的管理与应用是数据驱动企业转型升级的先决条件。基于区块链的企业数字资产管理(Digital Asset Management)系统可以解决传统企业数字资产管理系统的诸多弊端,如版权纠纷、隐私泄露、数据丢失、恶意篡改、单点故障等。区块链技术作为一种分布式账本技术,通过加密算法、共识机制、多点维护等技术手段能够保证链上数据的可信赖性和可验证性,降低中心化管理模式带来的风险。本文充分利用区块链去中心化、免信任、防篡改以及可回溯性等特点,结合数据指纹、安全认证机制、Token激励机制以及星际文件系统(InterPlanetary File System),设计了一种基于区块链的数字资产管理系统框架,并从数据存储、访问控制、效绩认证等多个角度出发对系统功能进行解析。该框架在区块链环境下能够有效保证企业数字资产的安全性、完整性、可操作性和一致性,为传统企业数字资产管理提供了一种新的策略。
The management and application of enterprise big data are a prerequisite for data-driven enterprise transformation and upgrading. The Digital Asset Management system based on blockchain of an enterprise can solve many drawbacks of the traditional enterprise digital asset management system, such as copyright disputes, privacy disclosure, data loss, malicious tampering, single point of failure, etc. As a distributed ledger technology, blockchain technology can ensure the trustworthiness and verifiability of data on the chain by encryption algorithm, consensus mechanism, multi-point maintenance and other technical means, and reduce the risk brought by centralized management mode. In this paper, a digital asset management system framework based on blockchain is designed by making full use of the characteristics of blockchain such as decentralization, nontrust, anti-tampering and traceability, combining data fingerprint, security authentication mechanism, Token incentive mechanism and InterPlanetary File System. The system functions are analyzed from the perspectives of data storage, access control, performance certification and so on. The framework can effectively guarantee the security, integrity, operability and consistency of enterprise digital assets under the blockchain environment, and provide a new strategy for traditional enterprise digital asset management.
