Transposition Error Detection in Luhn's Algorithm
Wangeci Wachira, Waweru Kamaku, Lewis N. Nyaga · 2015
In 1950's Han's Peter Luhn formulated the Luhn form ula (algorithm) to solve information storage and retrie val problem. This formula has been given worldwide application such as in the credit card numbers where it uniquely identifies an account to its resp ective owner among other applications. Insecurity and fraud cases associated with the credit cards have necessitated the need to analyze the algorithm erro r detection and correction capabilities. It is known that the transposition of digits 09 for 90 cannot be detected. The paper analyzes the detection of this transposition error and discusses key considerations in algorithm developme nt to avoid such an error.
