“…While graphical passwords are unlikely to fully replace text passwords on smartphones in the near future [6], promising applications are convenient and secure device access, as well as protection of password managers for text passwords, which has also been suggested in the browser context [3]. Thus, in practical use, graphical passwords may obviate the need to type text passwords on smartphones even without fully replacing them.…”

Smartphones have emerged as a likely application area for graphical passwords, because they are easier to input on touchscreens than text passwords. Extensive research on graphical passwords and the capabilities of modern smartphones result in a complex design space for graphical password schemes on smartphones. We analyze and describe this design space in detail. In the process, we identify and highlight interrelations between usability and security characteristics, available design features, and smartphone capabilities. We further show the expressiveness and utility of the design space in the development of graphical passwords schemes by implementing five different existing graphical password schemes on one smartphone platform. We performed usability and shoulder surfing experiments with the implemented schemes to validate identified relations in the design space. From our results, we derive a number of helpful insights and guidelines for the design of graphical passwords.

“…Example of CAPTCHA based on puzzle is shown in II. CLICK-BASED GRAPHICAL CAPTCHA Present technologies can easily break the text-based CAPTCHA's with minimum effort and within less time, to overcome this, a new graphical based CAPTCHA's are used where user uses an image as CAPTCHA [8,11]. In case of Text-Based CAPTCHAs user normally enters disorder strings as a CAPTCHA, the same is stored in the key loggers which is easy for spyware to decode it.…”

Software that gathers information regarding the computer's use secretly and conveys that information to a third party is Spyware. This paper proposes a click based Graphical CAPTCHA to overcome the spyware attacks. In case of traditional Text-Based CAPTCHA's user normally enters disorder strings to form a CAPTCHA, the same is stored in the key loggers where spywares can decode it easily. To overcome this, Click-Based Graphical CAPTCHA uses a unique way of verification where user clicks on a sequence of images to form a CAPTCHA, and that sequence is stored in pixels with a random predefined order. This paper also analyzes the proposed scheme in terms of usability, security and performance.

“…Bicakci et al [19] explored the use of using graphical passwords built into a browser extension, based on the notion that humans are better at memorising images than text. The aim of the software developed was to make passwords more usable, decreasing the likelihood of users engaging in risky security behaviour.…”

Reducing Risky Security Behaviours: Utilising Affective Feedback to Educate Users

2014

Despite the number of tools created to help end-users reduce risky security behaviours, users are still falling victim to online attacks. This paper proposes a browser extension utilising affective feedback to provide warnings on detection of risky behaviour. The paper provides an overview of behaviour considered to be risky, explaining potential threats users may face online. Existing tools developed to reduce risky security behaviours in end-users have been compared, discussing the success rates of various methodologies. Ongoing research is described which attempts to educate users regarding the risks and consequences of poor security behaviour by providing the appropriate feedback on the automatic recognition of risky behaviour. The paper concludes that a solution utilising a browser extension is a suitable method of monitoring potentially risky security behaviour. Ultimately, future work seeks to implement an affective feedback mechanism within the browser extension with the aim of improving security awareness. OPEN ACCESSFuture Internet 2014, 6 761
