Privacy concerns are impediments to broad-scale adoption of the Internet for purchasing decisions. Computer self-efficacy has been shown to be an effective predictor of behavioral intention and a critical determinant of intention to use Information Technology. This book is based on my PhD dissertation. The results from the empirical study showed that the correlation between computer self-efficacy and information privacy concerns was significant and positive; and there were differences between genders and among age groups regarding privacy concerns and their relationships with computer self-efficacy. This book is a guide for research communities and graduate students on understanding the relationships among antecedents and consequences of information privacy concerns and computer self-efficacy. It also provides guide for corporations to improve e-commerce by targeting privacy policy-making efforts to address the explicit areas of consumer privacy concerns; and for Information Technology practitioners to develop privacy protection tools and processes to address specific consumer privacy concerns.
