Challenges of Using Data Science in Finance

Despite obvious advantages, data science, unfortunately, might bring you some hard times. The truth is that operating vast volumes of data rarely means an effortless task. Yet, what are the main problems you should keep in mind when thinking about the flawlessness of financial data science? Let’s review a brief rundown of the biggest challenges you might face!

Fraud risks

As previously mentioned, fraud issues are one of the most significant concerns of the financial industry. Even though we’ve talked about it several times, there’s no need to underestimate the malignancy of results the fraudulent activities might cause. The possibility of detractors hacking your finance system is higher than you think. The frauds will constantly try to create a fake account with a stolen identity to apply for a loan. With automatic management, you might relax a little bit too much and accidentally make it slip!

Data security

Certainly, there are plenty of ways of collecting financial data. However, what is the indicator of their safety? Another vital concern for financial data science is accessing the data sets appropriately according to compliance requirements. With the integration of third parties, in our case — data scientists, it’s crucial to ensure permanent security and compliance with data protection regulations, for instance, a GDPR. In other cases, the situation might lead to financial penalties and audits by regulatory bodies, which will cost a fortune.

Data Security Visualization

Heavy regulations

As much as being an advantage, the heavy regulations of the financial industry might bring minor (or not) inconveniences. Absolutely, such measures are meant to prevent illegal activities and protect the privacy of sensitive data. Still, data science in this environment requires precise explainability for such fairness-focused regulations. A possible inaccuracy of the most explainable models, aka white box models, is the main reason for the data scientists’ frustration.
