E – Commerce Models with Their Privacy & Security

Abstract

E-Commerce refers to the purchase and sale of goods and/or  services via electronic channels, such as the Internet. Online  retail is convenient due to its 24-hour availability, global reach  and ease of customer service. Though purchasing items online is  a major facet, e-commerce is more than that. This type of  commerce can be useful at the enterprise level as well. E commerce is not just on the Web — it was first introduced in the  1960s via electronic data interchange (EDI) through value-added  networks (VANs). In the mid-1990s, e-commerce was  transformed with the introduction of Amazon and eBay. There are  four main categories of E-Commerce: B2B, B2C, C2B, and C2C.
