چکیده
|
From covid-19 mortality rate to image tampering, benford's law is used to detect fraudulent activities. the underlying assumption for using the law is that a ``regular dataset follows the significant digit phenomenon. in this paper, we address the scenario where a shrewd fraudster manipulates a list of numbers in such a way that while providing the desired statistics, it still complies with benford's law. we develop a framework that offers several degrees of freedom to such a fraudster, such as the minimum, maximum, mean, and size of the manipulated dataset. the conclusion further corroborates the idea that benford's law -if at all- should be used with utmost discretion as a means for fraud detection.
