Enhancing graphical password authentication on smartphones

Recently, smartphones have emerged into a widely used as an input device for Graphical Password Technique due to the supporting of a touchscreen. Most of the smartphones used for managing a business especially in online trading or storing such an important or sensitive data. However, most of the existing methods of Graphical Password Authentication are suffering from a variety of usability and security issues such as they are more vulnerable to shoulder surfing attack due to the visual interface, difficult to use, and difficult to remember. In this research, a comprehensive study was conducted to determine the issues of usability and security on the existing schemes. A new recognition base graphical password method has been proposed to improve the issues of usability and security by asking the user selecting his/her pictures from the mobile’s gallery or via camera. The evaluation process was conducted by questionnaire survey and the help of 35 participants from UTM, UM, UPM, and LIMKOWKING university. The finding shows that the participants were completely satisfied with the usability and security which means that the proposed scheme of Graphical Password is acceptable from usability and security points

Building and evaluating an inconspicuous smartphone authentication method

Tese de mestrado em Engenharia Informática, apresentada à Universidade de Lisboa, através da Faculdade de Ciências, 2013Os smartphones que trazemos connosco estão cada vez mais entranhados nas nossas vidas intimas. Estes dispositivos possibilitam novas formas de trabalhar, de socializar, e ate de nos divertirmos. No entanto, também criaram novos riscos a nossa privacidade. Uma forma comum de mitigar estes riscos e configurar o dispositivo para bloquear apos um período de inatividade. Para voltar a utiliza-lo, e então necessário superar uma barreira de autenticação. Desta forma, se o aparelho cair das mãos de outra pessoa, esta não poderá utiliza-lo de forma a que tal constitua uma ameaça. O desbloqueio com autenticação e, assim, o mecanismo que comummente guarda a privacidade dos utilizadores de smartphones. Porem, os métodos de autenticação atualmente utilizados são maioritariamente um legado dos computadores de mesa. As palavras-passe e códigos de identificação pessoal são tornados menos seguros pelo facto de as pessoas criarem mecanismos para os memorizarem mais facilmente. Alem disso, introduzir estes códigos e inconveniente, especialmente no contexto móvel, em que as interações tendem a ser curtas e a necessidade de autenticação atrapalha a prossecução de outras tarefas. Recentemente, os smartphones Android passaram a oferecer outro método de autenticação, que ganhou um grau de adoção assinalável. Neste método, o código secreto do utilizador e uma sucessão de traços desenhados sobre uma grelha de 3 por 3 pontos apresentada no ecrã táctil. Contudo, quer os códigos textuais/numéricos, quer os padrões Android, são suscetíveis a ataques rudimentares. Em ambos os casos, o canal de entrada e o toque no ecrã táctil; e o canal de saída e o visual. Tal permite que outras pessoas possam observar diretamente a introdução da chave; ou que mais tarde consigam distinguir as marcas deixadas pelos dedos na superfície de toque. Alem disso, estes métodos não são acessíveis a algumas classes de utilizadores, nomeadamente os cegos. Nesta dissertação propõe-se que os métodos de autenticação em smartphones podem ser melhor adaptados ao contexto móvel. Nomeadamente, que a possibilidade de interagir com o dispositivo de forma inconspícua poderá oferecer aos utilizadores um maior grau de controlo e a capacidade de se auto-protegerem contra a observação do seu código secreto. Nesse sentido, foi identificada uma modalidade de entrada que não requer o canal visual: sucessões de toques independentes de localização no ecrã táctil. Estes padrões podem assemelhar-se (mas não estão limitados) a ritmos ou código Morse. A primeira contribuição deste trabalho e uma técnica algorítmica para a deteção destas sucessões de toques, ou frases de toque, como chaves de autenticação. Este reconhecedor requer apenas uma demonstração para configuração, o que o distingue de outras abordagens que necessitam de vários exemplos para treinar o algoritmo. O reconhecedor foi avaliado e demonstrou ser preciso e computacionalmente eficiente. Esta contribuição foi enriquecida com o desenvolvimento de uma aplicação Android que demonstra o conceito. A segunda contribuição e uma exploração de fatores humanos envolvidos no uso de frases de toque para autenticação. E consubstanciada em três estudos com utilizadores, em que o método de autenticação proposto e comparado com as alternativas mais comuns: PIN e o padrão Android. O primeiro estudo (N=30) compara os três métodos no que que diz respeito a resistência a observação e à usabilidade, entendida num sentido lato, que inclui a experiencia de utilização (UX). Os resultados sugerem que a usabilidade das três abordagens e comparável, e que em condições de observação perfeitas, nos três casos existe grande viabilidade de sucesso para um atacante. O segundo estudo (N=19) compara novamente os três métodos mas, desta feita, num cenário de autenticação inconspícua. Com efeito, os participantes tentaram introduzir os códigos com o dispositivo situado por baixo de uma mesa, fora do alcance visual. Neste caso, demonstra-se que a autenticação com frases de toque continua a ser usável. Já com as restantes alternativas existe uma diminuição substancial das medidas de usabilidade. Tal sugere que a autenticação por frases de toque suporta a capacidade de interação inconspícua, criando assim a possibilidade de os utilizadores se protegerem contra possíveis atacantes. O terceiro estudo (N=16) e uma avaliação de usabilidade e aceitação do método de autenticação com utilizadores cegos. Neste estudo, são também elicitadas estratégias de ocultação suportadas pela autenticação por frases de toque. Os resultados sugerem que a técnica e também adequada a estes utilizadores.As our intimate lives become more tangled with the smartphones we carry, privacy has become an increasing concern. A widely available option to mitigate security risks is to set a device so that it locks after a period of inactivity, requiring users to authenticate for subsequent use. Current methods for establishing one's identity are known to be susceptible to even rudimentary observation attacks. The mobile context in which interactions with smartphones are prone to occur further facilitates shoulder-surfing. We submit that smartphone authentication methods can be better adapted to the mobile context. Namely, the ability to interact with the device in an inconspicuous manner could offer users more control and the ability to self-protect against observation. Tapping is a communication modality between a user and a device that can be appropriated for that purpose. This work presents a technique for employing sequences of taps, or tap phrases, as authentication codes. An efficient and accurate tap phrase recognizer, that does not require training, is presented. Three user studies were conducted to compare this approach to the current leading methods. Results indicate that the tapping method remains usable even under inconspicuous authentications scenarios. Furthermore, we found that it is appropriate for blind users, to whom usability barriers and security risks are of special concern

Implementation of Captcha as Graphical Passwords For Multi Security

To validate human users, passwords play a vital role in computer security. Graphical passwords offer more security than text-based passwords, this is due to the reason that the user replies on graphical passwords. Normal users choose regular or unforgettable passwords which can be easy to guess and are prone to Artificial Intelligence problems. Many harder to guess passwords involve more mathematical or computational complications. To counter these hard AI problems a new Captcha technology known as, Captcha as Graphical Password (CaRP), from a novel family of graphical password systems has been developed. CaRP is both a Captcha and graphical password scheme in one. CaRP mainly helps in hard AI problems and security issues like online guess attacks, relay attacks, and shoulder-surfing attacks if combined with dual view technologies. Pass-points, a new methodology from CaRP, addresses the image hotspot problem in graphical password systems which lead to weak passwords. CaRP also implements a combination of images or colors with text which generates session passwords, that helps in authentication because with session passwords every time a new password is generated and is used only once. To counter shoulder surfing, CaRP provides cheap security and usability and thus improves online security. CaRP is not a panacea; however, it gives protection and usability to some online applications for improving online security

Exploring human factors issues & possible countermeasures in password authentication

PhD ThesisThis thesis is concerned with usable security. It describes a series of experiments to understand users’ behaviour in the domain of password authentication. The thesis is comprised of two parts. Part 1 reports on experiments into how different persuasion strategies can be used to increase the strength of users’ password. Existing research indicates that the lack of persuasive elements in password guidelines may lead to a lack of motivation to produce strong passwords. Thus, an experimental study involving seventy-five participants was conducted to evaluate the effectiveness of a range of persuasion strategies on password strength. In addition this experiment explores how personality variables affect the susceptibility of users to persuasion. The results showed that passwords created by users who received password guidelines that include a persuasion strategy produce stronger passwords than a control group. In terms of the personality variables, the result shows that there are certain personality types that tend to produce slightly better passwords than others; but it is difficult to draw a firm conclusion about how personality affects susceptibility to persuasion. The second part of this thesis presents an innovative alternative to text-based passwords, namely, graphical password schemes. Graphical passwords take advantage of the superior ability of humans to remember graphics and pictures over text and numbers. Research shows that graphical password schemes are a promising alternative, but that they are susceptible to shoulder surfing attacks, resulting in scepticism about adoption. Thus in part 2 of the thesis, three innovative shoulder surfing defence techniques are proposed and implemented in a small-scale prototype with a specific focus given to one type of graphical password; The Draw-A-Secret (DAS) scheme. The results of two separate experimental studies involving sixty-five and thirty participants respectively to evaluate the proposed defence techniques from the perspectives of security and usability are presented. The results show that the technique which, on theoretical grounds, was expected to be quite effective, provides little protection. A second technique which did provide the best overall shoulder surfing defence; created usability problems. But a third technique provided a reasonable shoulder surfing defence and good usability simultaneously; a good balance which the other two techniques did not achieve. The proposed defence techniques and experimental results are directly relevant to other graphical password schemes of the same category with slight modification to suit the requirements of the scheme intended. In summary, the thesis contributes to the discussion of some key usability problems which exist around password authentication domains. All the proposed countermeasures are evaluated through a series of experimental studies which present several intriguing discussions and promising findings

Carp A Novel Approach To Address The Well-Known Image Hotspot Problem In Popular Graphical Password Systems

In a novel safety pre-historic based on hard AI problems, that is, a new relations of graphical password systems put together Captcha knowledge, which we call CaRP (Captcha as gRaphical Passwords). CaRP is click-based graphical passwords, where a series of clicks on a picture is used to gain a password. Different other click-based graphicalpasswords, images used in CaRP are Captcha confront, and a new CaRP image is make for every login effort. Captcha is now a criterion Internet security method to defend onlineemail and other services from creaturebattered by bots. This new concept has get just anincompleteachievement as evaluate with the cryptographic primitives basedon solid math problems and their extensive applications. This is a demanding and motivating open trouble

Risks and potentials of graphical and gesture-based authentication for touchscreen mobile devices

While a few years ago, mobile phones were mainly used for making phone calls and texting short messages, the functionality of mobile devices has massively grown. We are surfing the web, sending emails and we are checking our bank accounts on the go. As a consequence, these internet-enabled devices store a lot of potentially sensitive data and require enhanced protection. We argue that authentication often represents the only countermeasure to protect mobile devices from unwanted access. Knowledge-based concepts (e.g., PIN) are the most used authentication schemes on mobile devices. They serve as the main protection barrier for many users and represent the fallback solution whenever alternative mechanisms fail (e.g., fingerprint recognition). This thesis focuses on the risks and potentials of gesture-based authentication concepts that particularly exploit the touch feature of mobile devices. The contribution of our work is threefold. Firstly, the problem space of mobile authentication is explored. Secondly, the design space is systematically evaluated utilizing interactive prototypes. Finally, we provide generalized insights into the impact of specific design factors and present recommendations for the design and the evaluation of graphical gesture-based authentication mechanisms. The problem space exploration is based on four research projects that reveal important real-world issues of gesture-based authentication on mobile devices. The first part focuses on authentication behavior in the wild and shows that the mobile context makes great demands on the usability of authentication concepts. The second part explores usability features of established concepts and indicates that gesture-based approaches have several benefits in the mobile context. The third part focuses on observability and presents a prediction model for the vulnerability of a given grid-based gesture. Finally, the fourth part investigates the predictability of user-selected gesture-based secrets. The design space exploration is based on a design-oriented research approach and presents several practical solutions to existing real-world problems. The novel authentication mechanisms are implemented into working prototypes and evaluated in the lab and the field. In the first part, we discuss smudge attacks and present alternative authentication concepts that are significantly more secure against such attacks. The second part focuses on observation attacks. We illustrate how relative touch gestures can support eyes-free authentication and how they can be utilized to make traditional PIN-entry secure against observation attacks. The third part addresses the problem of predictable gesture choice and presents two concepts which nudge users to select a more diverse set of gestures. Finally, the results of the basic research and the design-oriented applied research are combined to discuss the interconnection of design space and problem space. We contribute by outlining crucial requirements for mobile authentication mechanisms and present empirically proven objectives for future designs. In addition, we illustrate a systematic goal-oriented development process and provide recommendations for the evaluation of authentication on mobile devices.Während Mobiltelefone vor einigen Jahren noch fast ausschließlich zum Telefonieren und zum SMS schreiben genutzt wurden, sind die Anwendungsmöglichkeiten von Mobilgeräten in den letzten Jahren erheblich gewachsen.

Der dritte Teil beschäftigt sich mit dem Problem der vorhersehbaren Gestenwahl und präsentiert zwei Konzepte, welche Nutzer dazu bringen verschiedenartige Gesten zu wählen. Die Ergebnisse der Grundlagenforschung und der gestaltungsorientierten angewandten Forschung werden schließlich verknüpft, um die Verzahnung von Gestaltungsraum und Problemraum zu diskutieren. Wir präsentieren wichtige Anforderungen für mobile Authentifizierungsmechanismen und erläutern empirisch nachgewiesene Zielvorgaben für zukünftige Konzepte. Zusätzlich zeigen wir einen zielgerichteten Entwicklungsprozess auf, welcher bei der Entwicklung neuartiger Konzepte helfen wird und geben Empfehlungen für die Evaluation mobiler Authentifizierungsmethoden

Image-based Authentication

Mobile and wearable devices are popular platforms for accessing online services. However, the small form factor of such devices, makes a secure and practical experience for user authentication, challenging. Further, online fraud that includes phishing attacks, has revealed the importance of conversely providing solutions for usable authentication of remote services to online users. In this thesis, we introduce image-based solutions for mutual authentication between a user and a remote service provider. First, we propose and develop Pixie, a two-factor, object-based authentication solution for camera-equipped mobile and wearable devices. We further design ai.lock, a system that reliably extracts from images, authentication credentials similar to biometrics. Second, we introduce CEAL, a system to generate visual key fingerprint representations of arbitrary binary strings, to be used to visually authenticate online entities and their cryptographic keys. CEAL leverages deep learning to capture the target style and domain of training images, into a generator model from a large collection of sample images rather than hand curated as a collection of rules, hence provides a unique capacity for easy customizability. CEAL integrates a model of the visual discriminative ability of human perception, hence the resulting fingerprint image generator avoids mapping distinct keys to images which are not distinguishable by humans. Further, CEAL deterministically generates visually pleasing fingerprint images from an input vector where the vector components are designated to represent visual properties which are either readily perceptible to human eye, or imperceptible yet are necessary for accurately modeling the target image domain. We show that image-based authentication using Pixie is usable and fast, while ai.lock extracts authentication credentials that exceed the entropy of biometrics. Further, we show that CEAL outperforms state-of-the-art solution in terms of efficiency, usability, and resilience to powerful adversarial attacks

Gamification of Cyber Security Awareness : A Systematic Review of Games

The frequency and severity of cyber-attacks have increased over the years with damaging consequences such as financial loss, reputational damage, and loss of sensitive data. Most of these attacks can be attributed to user error. To minimize these errors, cyber security awareness training is conducted to improve user awareness. Cyber security awareness training that is engaging, fun, and motivating is required to ensure that the awareness message gets through to users. Gamification is one such method by which cyber security awareness training can be made fun, engaging, and motivating. This thesis presents the state of the art of games used in cyber security awareness. In this regard, a systematic review of games following PRISMA guidelines was conducted on the relevant papers published between 2010 to 2021. The games were analyzed based on their purpose, cyber security topics taught, target audience, deployment methods, game genres implemented and learning mechanics applied. Analysis of these games revealed that cyber security awareness games are mostly deployed as computer games, targeted at the general public to create awareness in a wide range of cyber security topics. Most of the games implement the role-playing genre and apply demonstration learning mechanics to deliver their cyber security awareness message effectively
