Biometric Authentication and Identification Using Keystroke Dynamics: A Survey 116-139
Dependence on computers to store and process sensitive information has made it necessary to secure them from intruders. A behavioral biometric such as keystroke dynamics which makes use of the typing cadence of an individual can be used to strengthen existing security techniques effectively and cheaply.

Image Registration Using Log Polar Transform and Phase Correlation to Recover Higher Scale 90-105
Image registration is an important and fundamental task in image processing used to match two different images. Given two or more different images to be registered, image registration estimates the parameters of the geometrical transformation model that maps the sensed images back to its reference image.
