Before The Model Goes Live: A Privacy Risk and Data Ethics Checkpoint Framework for Deploying Machine Learning in Nigerian and UK Financial Institutions
Subject area: Science,Engineering and Technology · Area of research: Machine Learning
Abstract
In Nigerian financial institutions, and across the UK, machine learning (ML) is already part of the fabric of credit applications, fraud detection and customer onboarding processes, but privacy and ethical concerns are only tackled at the back-end, inconsistently or once the machine learning solution is deployed. There is no existing guidance that is consistent or organized around a single decision point that a model should pass before it is allowed to go live. This conceptual review attempts to fill that gap by bringing together literature and regulatory sources in both jurisdictions. It establishes the concept of privacy risk, data ethics, model deployment governance and model risk management, puts the analysis in the context of privacy by design, contextual integrity, accountability and fairness and compares the Nigerian and UK regulatory frameworks. Then it highlights the key privacy and ethical issues that occur during deployment. Based on this, the paper suggests the Pre-Deployment Privacy and Ethics Checkpoint Framework, a gated framework of six stages: data and purpose validation; privacy impact and lawful basis check; fairness and bias testing; explainability and human oversight; security and third-party review; and go-live approval with monitoring hand-off. There is an evidence requirement and a pass/fail gate for each stage, with a named owner for each stage. The paper provides a practical, jurisdictionally flexible structure which turns dispersed obligations into a deployable and auditable trail, and it sets out limitations and testing requirements to move to the point where the framework could be considered valid.
