Security Solutions--Integration of Privacy Computing and Blockchain

Despite the financial industry's rapid growth spurred by advancements in artificial intelligence (AI), which has introduced innovative services and improved efficiency, significant security challenges persist. As AI becomes more deeply integrated into financial systems, the risk of cyber threats also escalates. Complex algorithms can become targets for hackers, who may exploit them through algorithm manipulation, data tampering, and system vulnerabilities. Additionally, automated decision-making systems, which often lack transparency, can lead to unforeseen security risks and compliance issues. Furthermore, AI technology relies heavily on vast amounts of personal and financial data, and if this data is accessed by malicious actors, it could result in severe privacy breaches and financial losses. Therefore, while the financial industry benefits from the efficiency and innovation brought by technology, it must also place a high priority on enhancing security measures to address the evolving cyber threats and technical challenges.


At the same time, addressing the issue of data silos is crucial. Financial institutions have an increasing need for cross-domain modeling by integrating data from peers and other industries, such as telecom operators, internet platforms, and traditional enterprises. It is a significant challenge to use technological means to achieve data integration and value circulation while ensuring the security and privacy of data assets. Although financial institutions possess relatively rich financial data assets, they often lack other highly relevant multidimensional data, necessitating a heavy reliance on external industry data for cross-domain model construction and data mining. For instance, data from the telecommunications industry typically exhibits high quality and completeness, which can fully describe user profiles and potential groups. Combining these datasets can leverage the strengths and scenarios of both sectors, maximizing the value of the data.

Blockchain technology has become a crucial component of data security. With its features of data traceability, resistance to tampering, and automatic execution of smart contracts, blockchain enables closed-loop management of the entire data lifecycle. Its popularity has fluctuated over the past few years. Initially, blockchain was primarily associated with cryptocurrencies like Bitcoin, but its applications have now extended far beyond cryptocurrencies. Current hot areas include DeFi (Decentralized Finance) and NFTs (Non-Fungible Tokens).


Privacy computing refers to modern cryptographic and information security technologies, such as secure multi-party computation, homomorphic encryption, federated learning, and trusted execution environments.


The combination of blockchain technology and privacy computing has become an essential part of security solutions. Currently, the applications of blockchain and privacy computing are mainly in five directions: solving specific single-point problems, expanding the application scope of consortium blockchains, providing cybersecurity-related services, establishing blockchain + privacy computing infrastructure platforms for enterprises, and creating blockchain + privacy computing infrastructure platforms that serve both enterprises and individuals. The integration of blockchain and privacy computing is an effective technological means to solve data sharing challenges, build trusted operations, and achieve high-value data circulation.


Existing Challenges


1. Blockchain requires protection of on-chain data privacy.

  Blockchain faces significant challenges in protecting on-chain data privacy, including conflicts between data transparency and privacy needs, the risk of sensitive information being unable to be deleted due to the immutability of data, and the complexity and high cost of privacy protection technologies. Additionally, balancing privacy with transparency, complying with regulatory requirements in different regions, managing user privacy, lack of unified privacy protection technology standards, and the impact of privacy protection technologies on performance are all pressing issues that need to be addressed.


2. Security Needs Further Improvement

  Privacy computing usually assumes that participants in multi-party computation strictly adhere to protocol processes and that hardware providers are entirely trustworthy. However, these assumptions do not always hold true in practice. Additionally, during the commercialization of privacy computing technology, system security risks are inevitable. Given the high-security requirements of privacy computing products, any security vulnerabilities in the system become the most susceptible to attacks.


3. Privacy Computing Requires Greater Computational and Communication Load

  The large-scale application of privacy computing faces limitations in computational and network load, which can be tens to hundreds of times greater than traditional machine learning. Moreover, privacy computing involves multi-party synchronous computation, where any bottleneck in one party's computational or communication resources will directly limit the performance of the entire computing platform.


4. Difficulty in Achieving Security Consensus Among Parties

  Privacy computing requires multiple participants to reach a consensus on security. However, it is challenging for participants to intuitively verify each other's security, and currently, there is a lack of security grading standards for privacy computing.


5. Difficulty in Interconnecting Different Products

  Each privacy computing application faces the challenge of conducting multi-party computation with different institutions. However, since the privacy computing platforms deployed by each party may be based on specific algorithms and designs, it is difficult to achieve information interoperability between different platforms, leading to the need for repeated deployments.
