A growing concern of users about confidentiality and privacy in web related tasks presses companies to present more secure solutions that respect the right to individual privacy. However, as some sources show, the most common browsers on the market are not able to maintain adequate privacy, even with the adoption of private browsing mode. For law enforcement agents this vulnerability may give a chance to acquire evidence during an investigation. Information security or lack of it solidifies into issues that often are not technical. The first concept is the confidence. Conceptually, trust is the firm belief that one has in relation to another person or something. Certainly, several security incidents began in the confidence that software and hardware would not fail under certain conditions. This paper presents a data capture method of browsers related activities and argues that it is possible to recover text and graphics data related to pages visited during private browsing sessions. The observations, reported in this article, show a clear violation of the functional requirement to maintain user’s privacy. Overall, it is important to assess and validate private browsing techniques.
