Abstract: ABSTRACT: An overview of Benford's Law is provided and a methodology for its application in fraud detection is proposed. A case study is used to illustrate the application of digital analysis using Benford's Law via a financial review of a small chemical manufacturing plant: digital analysis facilitated fraud detection by enabling the speedy identification of suspicious purchasing transactions and resulted in the discovery and termination of fraudulent activities. Benford's Law is a theory of statistical probability that establishes the expected frequency of numbers that appear in a database. Where there are built-in biases, the data will not conform to Benford's Law. A general approach to utilizing digital analysis using Benford's Law for fraud detection is summarized in a flowchart. Digital analysis is best implemented as part of a more comprehensive approach to fraud detection involving inter alia training in ethics, the implementation of a hotline, a well-trained audit department, a profile of potential frauds to be tested, and the use of outside specialists to complement the internal resources
