Now a day's Signature verification is one of the most important features for checking the authenticity of a person. There are many security checking parameters like pin code, password, finger print checking but signature recognition is the most popular because it is quite accurate and cost efficient too. On the other hand one doesn't have to remember the authentication key like pin code or password. The signature of a genuine signer stays almost constant. But there may be little difference between well practiced forgeries and the genuine signer. It is required to distinguish these differences. This paper presents grid based, contour based and area based approach for signature verification. Intersecting points and centroids of two equal half of the signature is being calculated and then those centroids are connected with a straight line and the angles of these intersecting points with respect to the centroids connecting lines are calculated.
