As banks scramble to keep pace with the latest advancements in artificial intelligence, an emerging tool known as DeepSeek is making waves in the industryThis sophisticated model, renowned for its prowess in data processing, natural language understanding, and logical reasoning, is gradually embedding itself into various core operational scenarios such as credit assessments, contract management, and customer serviceHowever, the increasing incorporation of such technologies is accompanied by heightened concerns regarding data security, model risks, and regulatory compliance, which have become focal points for financial institutions.

In a recent interview with China Business Journal, Liu Tong, Deputy General Manager of the Product Center at the China Financial Certification Authority (CFCA), highlighted that while DeepSeek offers banks a path towards intelligent solutions with manageable risks, its implementation necessitates a careful balance between technological innovation and security complianceBanks need to leverage the advantage of AI while simultaneously reinforcing the financial security framework.

The journey for banks is shifting from solely enhancing efficiency to reconstructing their operational ecosystemNumerous banks have recently deployed DeepSeek models locally, utilizing them across a variety of applications including intelligent contract management, risk control, asset custody, valuation reconciliation, customer service assistants, and advisory roles.

However, there are significant pain points hindering banks' AI applicationsThese include imbalances in training costs versus energy efficiency, a deficiency in the ability to generalize across long-tail situations, and engineering challenges associated with edge-side deploymentLiu Tong contends that DeepSeek is breaking through these barriers by optimizing cost structures and integrating domestic technology stacks.

He provided various examples of how DeepSeek enhances efficiency, accuracy, and risk control capabilities in the banking sector, driving upgrades to smart financial infrastructure

In credit evaluations, the traditional processes that depend heavily on human handling of unstructured data are time-consuming and prone to errorsIn contrast, DeepSeek's exceptional capabilities in understanding Chinese language nuances and logical reasoning significantly streamline the automated parsing of loan materials, thereby enhancing the efficiency of credit reviewsWhen it comes to contract management, DeepSeek employs natural language processing to accurately identify contract terms while leveraging legal knowledge bases for compliance checksIn customer service scenarios, the model can tailor personalized assistance based on clients’ transaction histories and preferencesFor asset custody and valuation, DeepSeek's powerful data processing abilities facilitate the automated parsing and comparative analysis of transaction and valuation data.

According to Liu Tong, the implementation of DeepSeek is contributing to diminished 'Matthew effect' in the banking technology ecosystemWith the adoption of DeepSeek, banks can achieve intelligent applications across multiple scenarios while keeping risks under checkThis enables smaller banks to bridge the technological gap with larger institutions, which, in turn, can cultivate a more robust fintech ecosystem.

Nevertheless, questions arise regarding the accuracy of DeepSeek as an AI decision-making system in the context of risk assessmentLiu suggests that banks can ensure DeepSeek’s accuracy through rigorous measures at the data, model, and technological layersWhen asked about the necessity of establishing a third-party audit mechanism to prevent model biases or black-box decision-making risks, he pointed out that DeepSeek's open-source model offers public transparency through shared model code and training methodologiesThis transparency allows banks and related entities to scrutinize and validate the model, thereby potentially mitigating some of the risks associated with third-party audits and enhancing the integrity of the decision-making process.

Despite the promising applications of DeepSeek, the risks it introduces cannot be taken lightly

Liu emphasizes that banks must prioritize three major areas of risk: model attacks, algorithmic biases, and sensitive data breaches.

To counteract risks from model attacks, banks may enhance model robustness utilizing methods such as adversarial training and data augmentationLiu elucidates that while attackers might forge loan documents to deceive the system, fusion of results from multiple models can significantly reduce the rate of misjudgment.

Algorithmic bias poses additional concerns, with potential repercussions for compliance and reputationLiu insists that banks should proactively address this through diverse data collection, fairness constraints on algorithms, and dynamic feedback mechanisms to initiate corrections.

In tackling the threat of sensitive data breaches, Liu acknowledges that localized deployment of DeepSeek can minimize the risk of data outflowHowever, the model's operation still necessitates interaction with vast amounts of user data during training and inference, which, if mishandled, could infringe on user privacy, eroding trust and possibly leading to compliance issues.

In recent years, there’s been a push towards providing explanations regarding how data influences decision-making outcomes and ensuring information disclosure, alongside real-time monitoring of automated processes and resulting system behaviorsBanks are also advised to develop risk mitigation measures for AI applications, including crafting alternative exit strategies and emergency protocols for security threats with ongoing drills for preparedness.

When dealing with the risks associated with data, Liu advocates for employing desensitization techniques, access control measures, and monitoring/auditing technologies to safeguard customer sensitive financial information while leveraging DeepSeek.

For data desensitization, he outlines two core strategies: first, implementing specific encoding rules that render sensitive data unrecognizable without specialized algorithms; and second, encrypting financial data such as transaction passwords and national ID numbers, granting decrypt access solely to authorized users through secure key mechanisms.

Regarding access control measures, Liu explains that banks should utilize multifactor authentication methods—like usernames and passwords, digital certificates, rotating tokens, and biometric verification—to secure access to sensitive financial data
