LITERATURE REVIEW
Conceptual Framework
Concept of Artificial Intelligence (AI)
Artificial Intelligence (AI) is a branch of computer science focused on creating systems capable of performing tasks that typically require human intelligence, such as learning, reasoning, problem-solving, and understanding natural language. AI functions through algorithms and models that enable machines to mimic cognitive functions to automate and optimize tasks across various sectors, especially finance (Russell & Norvig, 2023). In essence, AI offers an avenue for revolutionizing how decisions are made in real-time, enhancing productivity and accuracy in data-driven environments.
The financial sector has been one of the early adopters of AI technologies, using them for applications such as fraud detection, customer service, and risk assessment. For instance, banks in Nigeria use AI algorithms to detect fraudulent transactions by identifying anomalies in transaction patterns (Eze & Chinedu, 2024). AI systems can process vast amounts of data at high speed, identifying complex patterns that would be difficult for humans to detect, thereby enhancing the security and integrity of financial systems.
A significant aspect of AI application in Nigerian banking is its contribution to improving financial inclusion. AI-driven digital banking platforms and automated credit-scoring tools enable banks and fintech firms to provide services to individuals who lack traditional financial history (Adebayo et al., 2023). This inclusion empowers underbanked populations by extending access to credit and savings products, ultimately reducing the financial divide in both rural and urban communities.
Customer service has also evolved significantly with the introduction of AI-powered chatbots, which are capable of handling thousands of inquiries simultaneously. These chatbots improve response time, reduce operational costs, and enhance customer satisfaction (Akinbami & Johnson, 2024). As the demand for personalized services increases, chatbots have become indispensable tools for banks aiming to maintain customer engagement around the clock.
Moreover, the integration of AI with other technologies such as blockchain has led to improvements in cybersecurity and transaction transparency. AI systems help monitor and identify security breaches, while blockchain ensures tamper-proof data management (Akinola & Ojo, 2023). This synergy enhances trust and reinforces IT security frameworks, especially in a financial ecosystem prone to cyber threats.

Research Design
Research design is a critical aspect of any study as it dictates the overall structure and strategy for data collection and analysis (Saunders, Lewis, & Thornhill, 2019). This study adopted a a cross-sectional and quantitative survey research design, which was deemed appropriate due to the objective of assessing the security impact of Artificial Intelligence (AI) in the financial sector. The survey design allows for the systematic collection of numerical data, which can be used to identify patterns, relationships, and correlations among the variables under investigation (Bell, Bryman, & Harley, 2019).
Quantitative research is effective when the study seeks to quantify variables, test hypotheses, and generalize findings to a larger population (Creswell & Creswell, 2018). In this case, the study aimed to evaluate the extent of AI deployment in the financial sector and its associated security risks, as well as the preparedness of financial institutions to address these challenges. A survey-based approach is ideal because it allows for the collection of data from a wide range of financial institutions, thereby providing a comprehensive understanding of the issue across different contexts and regions.
Population, Sample, and Sampling Techniques
The population for this study consisted of employees working in the IT and cybersecurity departments of various financial institutions, including commercial banks, insurance companies, and fintech firms, located in major cities such as Lagos, Abuja, Port Harcourt, and Kano. These individuals were selected because they are directly involved in the implementation and management of AI technologies and the cybersecurity measures in their respective organizations. According to the Central Bank of Nigeria (CBN) and the National Insurance Commission (NAICOM), these institutions represent the most technologically advanced financial organizations in Nigeria, thus providing the appropriate context for examining the integration of AI and its security implications.
To ensure the sample size was statistically significant, a simple random sampling technique was employed. This approach ensures that every member of the population has an equal chance of being selected, which minimizes bias and enhances the representativeness of the sample (Tavakol & Dennick, 2021). Given that the total number of employees in these departments is estimated to be around 2000 individuals across the selected regions, the sample size was determined using the Taro Yamane formula. This formula helps determine an optimal sample size based on the population size, margin of error, and confidence level (Charan & Biswas, 2019).
