Sinequa Assistant brings GenAI to the workplace Watch the video
A leading European bank and one of the world’s top 20 banks based on assets, working across retail banking, corporate and investment banking, wealth and asset management. This financial institution operates in 67 countries.
The bank wanted to identify confidential data to protect the privacy of its clients more consistently and efficiently. What makes this data difficult to find is that most of it is unstructured textual content from which the sensitive information must be mined. This content is spread across the bank systems, held in multiple formats, and constantly changes. Plus, much of this data is subject to regulations, especially, Non-Public Information (NPI) and Personally Identifiable Information (PII).
In order to mitigate the risks, the bank’s compliance team defined multiple confidentiality categories to apply to all content across the bank. Each employee creating or modifying a document was responsible for evaluating its confidentiality category and tagging it correctly. Only a small percentage of the staff knew and fully understood these classification guidelines.
The resultant cognitive burden imposed on employees came at a high price in terms of lost time, while also distracting private banking staff from building customer relationships. This might have been worthwhile, however, compliance with the process was unsystematic and inconsistent.
Critically, the bank also wanted to comply with regulatory mandates proactively while increasing security and reducing end user friction. This meant protecting both NPI (such as investment holdings) and PII (such as customer account numbers and Social Security numbers). The bank was keenly aware of breaching regulations, such as the General Data Protection Regulation (GDPR) that exposes companies to fines up to a maximum of 4 percent of the company’s global annual revenue. A recent infamous example was Equifax’s data breach, which cost the company $439 milion by the end of 2018, with total expected costs of over $600 million.
The initial project was in the bank’s Private Banking business.
As a first step, leveraging Sinequa’s AI-powered Search platform, the bank was able to analyze the full-text of documents, regardless of data source, format, or language. Content was ingested seamlessly from both structured sources (such as CRM, portfolio management, and performance measurement) and unstructured sources (such as email, Microsoft Office, scanned documents, and PDFs).
To understand the content of a document in multiple languages (English, French, German…), Sinequa leveraged its state-of-the-art Natural Language Processing capabilities (NLP) including:
Using NLP enabled the bank to tag documents and identify confidential information. Although additional context is required to understand the full meaning of a document. For example, an investment in a publicly listed equity would be tagged by NLP, irrespective of client objective or identity. However, a document’s confidential category will vary depending on whether it is held in a managed account of the portfolio of private wealth client. This is where AI and machine learning come into play. Sinequa’s machine learning capabilities can understand the difference.
To predict document confidentiality more precisely, Sinequa worked with the Risk & Compliance experts at the bank to build training sets and train machine learning models. These machine learning models, which continually learn and improve over time, were applied to millions of documents across multiple, global business units to predict confidentiality categories automatically and more accurately.
