Perceived privacy is defined as consumers’ ability to control presence of other people in the environment during a market transaction or consumption behavior and the dissemination of information related to or provided during such transactions or behaviors to those who were not present [Goodwin 1991]. Flavia´n and Guinalý´u [2006] demonstrated that trust in the Internet is particularly influenced by the privacy perceived by consumers regarding the handling of their private data. Privacy is a critical factor in acquiring potential online customers and retaining existing customers [Park and Kim 2003]. Thus, privacy can also be a critical factor in customer satisfaction of e-commerce services.
