Tightly-Held and Ephemeral Psychometrics: Password and Passphrase Authentication Utilizing User-Supplied Constructs of Self
نویسنده
چکیده
This research investigates the role of passwords and passphrases as valid authentication methodologies. Specifically, this research dispels earlier work that ignores information-theoretic lessons learned from cognitive and social psychology and psycholinguistics, and extends and enriches the current password security model.

Modeling Aggregate Security with User Agents that Employ Password Memorization Techniques
We discuss our ongoing work with an agent-based password simulation which models how site-enforced password requirements affect aggregate security when people interact with multiple authentication systems. We model two password memorization techniques: passphrase generation and spaced repetition. Our simulation suggests system-generated passphrases lead to lower aggregate security across servic...
متن کاملThe usability of passphrases for authentication: An empirical field study
In developing password policies, IT managers must strike a balance between security and memorability. Rules that improve structural integrity against attacks may also result in passwords that are difficult to remember. Recent technologies have relaxed the 8-character password constraint to permit the creation of longer pass-‘‘phrases’’ consisting of multiple words. Longer passphrases are attrac...
متن کاملA Preliminary Study of a New Soft Biometric: Finger Recognition for Keystroke Dynamics
Keystroke dynamics is an interesting biometric modality as a user can be authenticated while typing a passphrase or a password on a keyboard. In order to improve the accuracy of biometric systems, it is possible to exploit some prior information that can be known or extracted from the biometric raw data. This process is known as ”soft biometrics”. In this paper, we propose a new soft biometric ...
متن کاملBiometric Authentication of Fingerprint for Banking Users, Using Stream Cipher Algorithm
Providing banking services, especially online banking and electronic payment systems, has always been associated with high concerns about security risks. In this paper, customer authentication for their transactions in electronic banking has been discussed, and a more appropriate way of using biometric fingerprint data, as well as encrypting those data in a different way, has been suggest...
