  • From Mini House Game to Hobby-Driven Behavioral Biometrics-Based Password
    2013 12th IEEE International Conference on Trust Security and Privacy in Computing and Communications, 2013
    Co-Authors: Weiyu Jiang, Ji Xiang, Limin Liu, Daren Zha, Lei Wang
    Abstract:

    It is believed that one of the major problems botheringpeople is that the password is prone to be forgotten whensigning in services on the Internet. Although both recognitionbasedgraphical password schemes and behavioral biometricsbasedpassword schemes have been widely known in the field ofinformation Security because of their relatively High Security leveland being easy to memorize, the remaining Security problems ongraphical password schemes and accuracy issues upon behavioralbiometrics-based password schemes are still great bottlenecks, which prevents them from being populated. In this paper acomprehensive study on habitual behaviors driven by hobbies willbe presented firstly. Then a novel authentication system, whichreaches a reasonable High Security Standard and accuracy level bycombining the hobby-driven behavioral biometric technique andrecognition-based graphical password techniques, is introduced. The key characteristic of the system lies in behavioral featuresrelated to style, color, position and habitual operating order ofthe object images for authentication. These metrics are relativelyunique from person to person but steady because such a repeatedbehavior in daily life is a hobby-driven habitual behavior. Andfinally, the experiments' result analysis is available, which showsthat the novel authentication system can maintain robust whenfacing traditional attacks while stay easy to remember at thesame time.

  • Toward web-based information Security knowledge sharing
    Information Security Technical Report, 2013
    Co-Authors: Daniel Feledi, Stefan Fenz, Lukas Lechner
    Abstract:

    Abstract Today IT Security professionals are working hard to keep a High Security Standard for their information systems. In doing so, they often face similar problems, for which they have to create appropriate solutions. An exchange of knowledge between experts would be desirable in order to prevent developing always the same solutions by independent persons. Such an exchange could also lead to solutions of Higher quality, as existing approaches could be advanced, instead of always reinventing the Security wheel. This paper examines how information Security knowledge can be shared between different organizations on the basis of a web portal utilizing Web-Protege. It can be shown that through the use of ontologies the domain of information Security can be modeled and stored in a human- and a machine-readable format, enabling both human editing and automation (e.g. for risk calculations). The evaluation of the web portal has shown that the most important challenge a tool for knowledge sharing has to face is the aspect of motivating users to participate in a knowledge exchange. Results from the evaluation have been used to further develop and enhance the web portal by implementing additional facilitating features. These features include a credit system, which rewards users for contributions, as well as the ability to select multiple entities, improving the system's usability.

  • Trustcom/BigDataSE/ISPA - On Designing Leakage-Resilient Vibration Based Authentication Techniques
    2016 IEEE Trustcom BigDataSE ISPA, 2016
    Co-Authors: Nilesh Chakraborty, Gurpinder Singh Randhawa, S. Vijay Anand, Samrat Mondal
    Abstract:

    To prevent shoulder surfing attack, a secured channel between the device and user must be established so that it cannot be eavesdropped by an adversary. In this paper we have explored vibration signals to design authentication services namely - (a) VDLS and (b) M-VDLS to resist shoulder surfing attack. The use of vibration provides a key strength to bypass the threat of shoulder surfing without using any auxiliary device. Thus, proposed schemes in this paper avail aforementioned advantage to address the attack. While VDLS attains very High Security Standard compared to existing approaches, M-VDLS ensures High usability Standard to avoid the attack in mobile environment. Both these approaches are also capable of providing solution against classical shoulder surfing attack without any information leakage. Finally, we show that required overheads of proposed approaches are reasonable in practice and outperform the existing approaches in terms of Security and usability.
