Privacy and security concerns for online share trading

Abstract

Online share trading has made investing in share markets more accessible to novice traders. Investors can trade from the comfort and privacy of their own homes. However, there are many inherent risks in online share trading. Share markets are becoming the target of new elaborate scams, terrorist attacks and corporate crimes. This paper provides an overview of privacy and security for online share trading in the context of auctions. We discuss the additional parties involved, and how their individual requirements affect auction security and privacy. We give a description of share market related crimes and their implications for online trading. We investigate existing security mechanisms and cryptographic solutions to these problems. This paper presents an auction scheme for anonymous and secure share transactions.
