A comparison of password techniques
A widely used access control mechanism is the password. Passwords are normally composed of a meaningful detail, such as a name of a person or a sequence of numbers such as birthdate. Any person attempting to gain unauthorized access to a system might need only to look at a personnel record or …

PassDB : parser for password dump database
… of building a system that can be used to parse passwords and emails from most data dumps given (i.e., data leakage after security breach) and store them in some standard form within a database. The project had a special emphasis on automating the parsing of data dumps as much as possible. An …

Password secured systems and negative authentication
… concern. In the majority of our systems, passwords are the keys to the system. Unfortunately, there has been little innovation and vulnerabilities keep mounting. Even with established and well known defenses, no authority has emerged to establish policies or laws that guarantee their …

Username and password verification through keystroke dynamics
Most computer systems rely on usernames and passwords as a mechanism for access control and authentication of authorized users. These credential sets offer marginal protection to a broad scope of applications with differing levels of sensitivity. Traditional physiological biometric systems such as …

Pass-Go, a new graphical password scheme
… game, Go, we have designed a new graphical password scheme, Pass-Go, in which a user selects intersections on a grid as a way to input a password. While offering an extremely large password space (256 bits for the most basic scheme), our scheme provides acceptable usability, as empirically …

THE CLASSROOM PASSWORD GROUP CONTINGENCY WITH RANDOMIZED REINFORCERS
… as a classroom intervention is The Classroom Password. Following the implementation of The Classroom Password intervention with randomization components, student behavior on a class-wide and individual target student level demonstrated an increase in academically engaged behavior (AEB) and a …

PiXi: an approach to nudge secure password creation
Passwords, a first line of defense against unauthorized access, must be secure and memorable. However, people often struggle to create secure passwords they can recall. To address this problem, we design Password inspiration by eXploring information (PiXi), a novel approach to nudge users towards …

One Time Password Scheme Via Secret Sharing Techniques
… mechanism to prove one's identity. One-time passwords in the form of hardware tokens in combination with conventional passwords have emerged as the predominant means in high security environments to satisfy the independent identification criteria for strong authentication. However, current …

CredProxy: A Password Manager for Online Authentication Environments
… the one hand, generation of strong usernames and passwords is a difficult task for the user. On the other hand, memorization of strong passwords is by far more problematic for the average user. Thus, the average user has a tendency to use weak passwords, and also reuse his passwords for more than …

Usability and security of recognition-based textual password
Knowledge-based passwords are still the most dominant authentication technique for authentications purposes, in spite of the emergence of alternative systems such as token-based and biometric systems. This approach has remained the most popular one mostly because of its user familiarity, …

Children's Text Password Behaviors and Parental Advice
… 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 …

A study of password recall, perceived memorability, and strength using BCIs
Passwords are considered the most common method of authentication and studies are frequently conducted to understand users' password habits. In this thesis, we run two empirical studies that provide information to further our understanding of the trade-o_ between security and usability in …

Improving Authentication for Users via Better Understanding Password Use and Abuse
Passwords are our primary form of authentication. Yet passwords are a major vulnerability for computer systems due to their predictable nature, in fact Florêncio et al., conclude that human limitations makes what is often considered to be “proper password use” impossible [52]. It is vital we …

Password-less two-factor authentication using scannable barcodes on a mobile device
<p>Currently, passwords are the default method used to authenticate users. As hardware continues to advance in speed, breaking these passwords becomes easier. The traditional solution to this problem is ever increasing password complexity and two-factor authentication. However, users become …

Raising the bar for password crackers: improving the quality of honeywords with deep neural networks
Honeywords are fictitious passwords inserted into databases in order to identify password breaches. Producing honeywords that are difficult to distinguish from actual passwords automatically is a time-consuming and sophisticated task, and the majority of existing research assumes that attackers …

The Classroom Password: An Independent Group Contingency Targeting Academic Engagement and Disruptive Behaviors In High School Classrooms
<p>The classroom password, an independent class-wide group contingency, was implemented in a high school setting in effort to determine its effects on academically engaged behaviors, disruptive behaviors and passively off-task behaviors. This was done using a reversal design across three classes. …

Improving the Eco-system of Passwords
<p>Password-based authentication is perhaps the most widely used method for user authentication. Passwords are both easy to understand and use, and easy to implement. With these advantages, password-based authentication is likely to stay as an important part of security in the foreseeable future. …
