User authentication through keystroke biometrics
Increased use of automated information systems together with our dominant use of computers has made our lives, making us totally dependent on computers and digital networks. Technological advances over the past decade have resulted in improved network services, in particular in the areas of performance, reliability, and availability, and substantially lower operating costs due to more efficient use of these achievements.
Some recently developed authentication Mechanisms require users to a specific enforcement action, then some of the behaviors of those activities is considered. The traditional method of signature verification falls into this category. Handwritten signatures extremely hard to fake to do without the help of some of the Copier.
A number of identification solutions based on some physiological aspect known as biometrics-appeared. Biometrics, physical traits and behavioral characteristics that make each of us unique, is the natural choice for identification. Biometrics is a great year to verify identity because the candidate keys or passwords, biometrics cannot be lost, stolen or overheard, and in the absence of physical damage Potential they offer ošibkoustojčivoe way to determine someone's identity. Physiological (i.e., static) characteristics, such as fingerprints, has good candidates for testing, because they are unique to a large segment of the population. Indispensable for all biometric systems to recognize that person, and they are both physiological and behavioral characteristics Encompass.
There are two kinds of biometrics. One has to deal with the physical characteristics of the user and the other deals with behavioral characteristics of the user. Retinal scan, fingerprint, which makes recognition, voice recognition and DNA testing under the first category comes while typing rhythm comes later into the category.
Physiological characteristics, such as fingerprints on a stable physical characteristics that is unchanged without causing injury to the person. Behavioral traits, on the other hand, there are some physiological basis, but also to respond to the psychological portrait of the man.
Most systems use a personal identification code to authenticate the user. In these systems the possibility an attacker gets access to the code can not be ruled out. However, combing the personal code from biometric data provides strong user authentication system.
Authentication using the rhythm of the user typing on the keyboard or the keyboard will take advantage of the fact that each user has a unique way of entering keys. It makes use of the interdependence of stroke is the gap between successive characters of the code identify the user.
When considering any authentication system, you must consider the false acceptance and false rejection.
False Acceptance Rate (FAR) is percentage-user requirements adopted in the system and drop the false Rate (FRR) is the percentage of users authorized not accepted by the system. increase in one of these targets reduces the other and vice versa. Accuracy level should be monitored in the system authentication using threshold Is only relevant users is the Policy chosen and the rest who do not authorisedfield rejected by the system.
