ABSTRACT
Fraudulent practices in Nigerian Deposit Money Banks (DMBS) have led to increased losses and collapse of deposit banks, hence the need to use digital forensics services to detect and prevent such fraudulent activities. The banking industry is a very important institution with many internal controls in order to overcome the fraudulent practices. The objective of this study was to examine the impact of digital forensics services on fraud detection and prevention among deposit money banks in Nigeria, the most prevalent type of fraud and to establish the major areas of application of digital forensics services. The data collection instrument preferred for the study was a questionnaire. Findings from the study saw that fraud detection and prevention increased when digital forensics services was employed. The study used descriptive research survey design and uses a sample of 47 respondents in United Bank for Africa (UBA), Ilaro branch. The data was analyzed using Statistical package for social sciences (SPSS). The study findings indicated that the application of digital forensics services by banks led to increased fraud prevention in the commercial banks and the highest application was on enhancing quality of financial reporting.
