scholarly journals Anti-Spoofing Authentication

Biometrics,One Among the existing security authentication schemes, involves parts of body for identification, hence used in various fields. Due to the level of its simplicity fingerprint recognition remains popular. But the introduction of many technologies has made to lose its uniqueness by just taking a finger print scan, print it on special paper and then swipe. This project is mainly designed to new optical method, which is based on liveness detection on fingers. Infrared pulse sensor which is a new method is employed to enhance image contrast of the finger vein and to know the pattern of blood flow for liveness detection.

The article presents the results of studies assessing the structure of cellular concrete using a photo-optical method based on the use of a modern approach from the standpoint of information technology. Based on the photo-optical method, a reverse formulation of the problem is also possible: on the basis of a given percentage of porosity of the material, obtain the most optimal pore arrangement (type of packaging) that meets the specified strength and thermal conductivity of aerated concrete. Having a specific type of image of aerated concrete obtained as a result of modeling, otherwise, a specific type of packing of pores of certain sizes that meets the required (specified) characteristics, then, we can set the technological task of obtaining it.

— The demand for simple, convenient and high security authentication systems protecting private information is rising with the development of improved consumer electronic devices. In existing systems cards, pin numbers and passwords are used for authentication. However theft of cards and guessing of pin numbers and passwords by exploiters is a serial threat. Hence the need to protect private information by means of biometric solutions is very essential. The proposed system finger vein recognition system is a biometric authentication system. The maximum curvature method of feature extraction used here extracts the centrelines without being affected by fluctuations in vein width and brightness. The results of processing are sent using GSM to owners or administrators. The system can be used for application such as bank ATM identification and verification, automatic door locking control systems and automated attendance register system.

Purpose Biometric systems are widely used for face recognition. They have rapidly developed in recent years. Compared with other approaches, such as fingerprint recognition, handwriting verification and retinal and iris scanning, face recognition is more straightforward, user friendly and extensively used. The aforementioned approaches, including face recognition, are vulnerable to malicious attacks by impostors; in such cases, face liveness detection comes in handy to ensure both accuracy and robustness. Liveness is an important feature that reflects physiological signs and differentiates artificial from real biometric traits. This paper aims to provide a simple path for the future development of more robust and accurate liveness detection approaches. Design/methodology/approach This paper discusses about introduction to the face biometric system, liveness detection in face recognition system and comparisons between the different discussed works of existing measures. Originality/value This paper presents an overview, comparison and discussion of proposed face liveness detection methods to provide a reference for the future development of more robust and accurate liveness detection approaches.
