Preserving Privacy and Fairness for an Innovative E-Commerce Model: Penny M-lottery

Abstract

Lottery games are prevalent worldwide because they provide participants with the opportunity to win a big fortune. With the development of the Internet, the practicability of online lotteries has advanced, because players can purchase lottery tickets online rather than at physical stores. However, the price of participating in traditional e-lottery is high so that not most players can join the game. Therefore, a novel type of lottery called penny lottery has been introduced. The price of penny lottery participation is lower than that of a traditional lottery, but it still offers people the opportunity to be a millionaire; thus, leading to fascination for participants with budget deficits. In recent years, the technology of mobile devices has developed rapidly. Applications are increasingly available in mobile environments. Consequently, we aim to develop an efficient mobile penny lottery mechanism called penny M-lottery. This mechanism could realize the fairness and offer privacy to participants. In addition, the process accuracy is verified through BAN logic and the security is confirmed by AVISPA. Experimental results revealed that the mechanism can be implemented in mobile environments because of the low computational costs and communication overheads.
