Design and Implementation of a Secure Online Lottery System

Government has the authority to operate lottery schemes. Since the operation of the lottery system is controlled by the government, there are issues with public trust. The people may speculate that the lottery is rigged. This issue becomes critical with an online lottery system since the unprotected data can be easy manipulated. If all combinations which have been sold are known before the drawing, the government may draw winning numbers which pay the least. Moreover, winning tickets may be added after the drawing. As a result, corruption may be inevitable. The government should operate lottery schemes with integrity which include transparency and accountability. This paper presents the design and the implementation of a secure online lottery system. The proposed system can provide accuracy, privacy, transparency, and verifiability. Using the proposed system, the government can operate lottery schemes with integrity.
