“…It can be configured to retrieve information from memory using recognition, free-recall or cued-recall. Assal et al [3] conducted a study to understand differences between children and adults authenticating using three PassTiles schemes. The three main variations of PassTiles used in the study are: Objects [34], Image [34], and Words [38] schemes.…”

“…[25] findings; they found that young children do not have good mental models privacy. Assal et al [3] recommend that when designing authentication systems for children, we need to take into consideration their cognitive abilities and skills. They propose three design recommendations for authentication system designed for children: facilitate memorization through learning and training features; adapt the interface to be age-appropriate for children; combine schemes to improve memorability (Objects and Images).…”

With increasing use of technology and the Internet among children, it is imperative to understand how they create passwords to protect their personal information, and also the parental advice they get to create these passwords. To understand this, we conducted two studies. The first study was conducted with children ages 11 to 13 to understand their password practices. The second study was conducted with parents to understand their own password behaviors and the strategies they teach their children to create secure passwords. The results of the studies indicated that children between ages 11 to 13 create simple passwords but believe that these passwords are hard for a stranger to guess. We also found that parents are concerned about their child's safety, but parents who are more aware of security-related cues are more likely to create secure passwords and teach their children to do the same. I would also like to thank my thesis committee members for reading my thesis

“…This method is vulnerable because attackers can capture the characters key in by the user and subsequently use it to login legitimately. Assal et al proposed an authentication method in 2016 [10]. During the registration procedure, a user is required to register five images from the images shown in the 8 x 6 grid cell.…”

The emotional stress and uncertainties associated with foreign exchange (forex) trading due to the high risk of losing the investment capital has left most forex traders in a state of indecision on the best methodology to apply for achieving long term profit. The provision of lot sizes, leverages, take profits and stop losses in forex trading implies that very high profit can be made within a very short time with the same capital, but at the same time, very high losses can be incurred. On one hand, this provision often prompts a set of traders to become greedy by increasing their take profit levels, lot sizes and leverages, which in turn increases their probability of losing out. On the other hand, the provision creates doubts and induces the fear of losses in some other set of traders. Consequently, these set of conservative traders employ the use of relatively small lot sizes, low leverages and low values of take profit and high stop loss levels. This in turn often results in a devastating effect on the investment capital due to lost opportunities and resulting losses. The problem of losses in forex trading effort is compounded by the fact that many programmers and developers of forex expert advisors do not adopt a software life cycle, having learned only how to write codes to program the trading platform. Furthermore, software engineering professionals who understand the import of software development life cycles soon discover that conventional software life cycles are not capable of effectively handling the complexity of the forex market. This paper models the human characteristics of greed, fear and doubt as manifested by traders in forex trading using selected expert advisors’ properties. It proposes Facts, Analysis, Implementation, Testing and Hope (FAITH) software life cycle model for Forex trading profitability to tackle the problem of indecision in the development of forex expert advisors. The proposed model was implemented on a live trading platform for a period of three months and compared with doubt, fear and greed approach to trading. The results showed that while a level of greed can be profitable, FAITH software life cycle produced more profitable results and can be adopted for forex trading.

“…Authentication can be categorised into three categories: token-based, biometric-based and knowledge-based [1]. Token-based authentication relies on what the users possess (e.g., ID card) to perform authentication, biometric-based authentication relies on users' attributes (e.g., thumbprint) to perform authentication, while knowledge-based authentication relies on what the users know (e.g., alphanumeric password) to perform authentication [1][2][3][4][5][6][7][8][9][10][11][12].…”

LocPass: A Graphical Password Method to Prevent Shoulder-Surfing

et al. 2019

Graphical passwords are a method of authentication in computer security. Computer security is one of the disciplines of computer science. Shoulder-surfing attacks are a well-known threat to graphical passwords, although is getting commonly used especially in granting access for a secure system. Shoulder-surfing occurs when attackers skillfully capture important data/activities, such as login passwords, via direct observation or video recording methods. Many methods have been proposed to overcome the problem of shoulder-surfing attacks. After we reviewed some related works, we found out that most of the existing methods are still vulnerable to multiple observations and video-recorded shoulder-surfing attacks. Thus, we propose a new method to combat this problem. In our proposed method, we make used of two concepts to combat shoulder-surfing attacks. In the first concept, we used registered locations (something that only the users know) and 5 image directions (something that the users can see) to determine a pass-location (new knowledge). Secondly, the images used in our proposed method have higher chances to offset each other. The idea of offset could increase the password spaces of our proposed method if an attacker intended to guess the registered location used. By combining these two concepts, the pass-location produced by our proposed method in each challenge set could be varied. Therefore, it is impossible for the attackers to shoulder-surf any useful information such as the images/locations clicked by the user in each challenge set. A user study was conducted to evaluate the capabilities of the proposed method to prevent shoulder-surfing attacks. The shoulder-surfing testing results indicated that none of the participants were able to login, although they knew the underlying algorithm and they have been given sufficient time to perform a shoulder-surfing attack. Therefore, the proposed method has proven it can prevent shoulder-surfing attacks, provided the enrolment procedure is carried out in a secure manner.
