There is a need of strong biometric system that resolve the issues related to those who use illegal way to break the system, those with change in psychological and behavioural characteristics and specially to those disable people (people with no limbs, bad retina, facial changes, etc.). The Cephalometric analysis is a strong tool based on image processing of human skull that can be used mathema...

2 Abstract Role-based access control (RBAC) is a promising alternative to traditional discretionary and mandatory access controls. In RBAC permissions are associated with roles, and users are made members of appropriate roles thereby acquiring the roles' permissions. In this paper we formally show that lattice-based mandatory access controls can be enforced by appropriate connguration of RBAC c...

Access Control is the process or mechanism for giving the authority to access the specific resources, applications and system. Access control defines a set of conditions or criteria to access the system and its resources. There are three main accesses Control model first is Mandatory access control model, second is Discretionary access control model and third is Role based access control models...

Nowadays, Iris recognition is a method of biometric verification of the person authentication process based on the human iris unique pattern, which is applied to control system for high level security. It is a popular system for recognizing humans and essential to understand it. The objective of this method is to assign a unique subject for each iris image for authentication of the person and p...

Biometric system has been actively emerging in various industries and continuing to roll to provide higher security features for access control system. The proposed system simultaneously acquires the finger surface and subsurface features from finger-vein and finger print images. This paper reviews the acquired finger vein and finger texture images are first subjected to pre-processing steps, w...

Inhabitants in smart environments are often authenticated when they enter the smart environment, e.g., through biometrics or smart-/swipe-card systems. It may sometimes be necessary to re-authenticate when an inhabitant wishes to enter a restricted area or access ambient services or location based information, e.g., it is common to have swipe card terminals placed next to doors to restricted ar...

The biometric person authentication technique based on the pattern of the human iris is well suited to be applied to any access control system requiring a high level of security. Commercial iris recognition systems are currently employed to allow passengers in some airports to be rapidly processed thru security, to allow access to secure areas, and for secure access to computer networks. With i...

While Mandatory Access Controls (MAC) are appropriate for multilevel secure military applications, Discretionary Access Controls (DAC) are often perceived as meeting the security processing needs of industry and civilian government. This paper argues that reliance on DAC as the principal method of access control is unfounded and inappropriate for many commercial and civilian government organiza...

In this paper, we propose a new security enforcement mechanism and demonstrate how this mechanism can enforce policies for both mandatory access control (MAC) and discretionary access control (DAC) in an object database system. Each class may have a security method that can block messages that leave instances of the class, and can block messages directed to instances of the class. Each supercla...
