Two Level Security System Using Matlab
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2015, Vol 3, Issue 12
Abstract
Two levels security system include Face Recognition and Password based entry control. Two level security(Face recognition and PIN) can provide hi-tech security at public place including International Airport, Metro-Station, Shopping Mall, banking ATM control and home etc. It increase human computer interaction which is fast and secure. This paper addresses first level i.e. the building of face recognition system by using Principal Component Analysis (PCA) method and second level Edsim51Di simulator for keypad entry and finally controlling the motor. A PCA algorithm is written on MATLAB. PCA [31], [33], [37] is a statistical approach used for reducing the number of variables in face recognition. As extracting the most information (feature) contained in the images (face). In PCA, every image in the training set can be represented as a linear combination of weighted eigenvectors called as “Eigen faces”. These eigenvectors are obtained from covariance matrix of a training image set called as basis function. Recognition is performed by projecting a new image (test image) onto the subspace spanned by the Eigen faces and then classification is done by distance measure methods such as Euclidean distance. Finally, when the face is matched, MATLAB program generate the 8bit hex code which is received at the port of 8051, further this project is simulated with the help of Edsim51di, first matches face code from database and secondly password entered by keypad which is interface with 8051 to match with the stored database and motor is rotated to allow the entry. If any one condition not satisfies it display “No Entry” at LCD
