How to Attack Biometric Systems in Your Spare Time
نویسنده
چکیده
Biometric systems were proposed and developed to provide a better and stronger factor of authentication. Such systems authenticate individuals based on physical and behavioral traits such as fingerprints, iris, face, palm print, hand geometry, voice, etc. The use of biometric traits to replace existing passwords or as access keys has proven to be highly secure against physical attacks. It is a fact that malicious attacks are getting smarter, more widespread and increasingly difficult to detect, and dozens more are added to the menagerie each day. Attacking biometric systems physically is quite difficult indeed. However, by mounting digital attacks one can see how biometric systems are vulnerable. We discuss the different types of software and hardware vulnerabilities that exist in biometric systems, and show how biometric template security can be compromised. We present a new attack point at the application level that has not been addressed and discussed in previous work. We also describe how biometric cryptosystems can overcome some of the disadvantages in traditional biometric recognition systems, and show how such systems can be used effectively in Digital Rights Management (DRM) systems.

A new model for Assessment and Optimization of Number of Spare Transformers and their Locations in Distribution Systems
In this paper, a new model has been presented to determine the number of spare transformers and their locations for distribution stations. The number of spare transformers must be so that they need minimum investment. Furthermore, they must be sufficient for replacing with transformers that have been damaged. For this reason, in this paper a new purpose function has been presented to maximize p...
متن کاملThe Biometric Values of Affected and Fellow Eyes in Patients with Acute Attack of Primary Angle Closure
Background: It has been estimated that 67 million people worldwide are affected with a primary glaucoma and that one-third have primary angle closure glaucoma. We aimed to determine the biometric differences between the eyes of patients with acute attack of primary angle closure and their non-involved fellow eyes. Methods: Twenty eight patients with acute attack of primary angle closure were re...
متن کاملA collusion attack on the fuzzy vault scheme
The Fuzzy Vault scheme is an encryption scheme, which can tolerate errors in the keys. This leads to the possibility of enhancing the security in environments where these errors can be common, such as biometrics storage systems. Although several researchers have provided implementations, we find that the scheme is vulnerable to attacks when not properly used. This paper describes an attack on t...

Anxiety is a mental state that is elicited in anticipation of threat or potential threat. Sensations of anxiety are a normal part of human experience, but excessive or inappropriate anxiety can become an illness. Anxiety is part of the normal human experience. We may speculate that it served human survival during evolution by enhancing preparedness and alertness. However, anxious manifestations...
متن کاملUsing A Central Data Repository For Biometric Authentication In Passport Systems
Passports and visas are currently undergoing a rapid change due to legislation being passed by authorities such as the US requirement that they should have machine readable biometrics embedded within them. What the governments are trying to accomplish is to positively link individuals to these identity documents. But if an impostor is capable of forging a passport, complete with embedded biomet...
