Secure ATM By Image Processing

This paper encloses the information regarding the ‘IMAGE PROCESSING’. And discussed one of the major application of image processing ‘BIOMETRICS’. Biometrics technology allows determination and verification of ones identity through physical characteristics. To put it simply, it turns your body in to your password. We discussed various biometric techniques like finger scan, retina scan, facial scan, hand scan etc. Two algorithms have been proposed by taking biometric techniques to authenticate an ATM account holder , enabling a secure ATM by  image processing. Biometrics is now applied in various public and private sectors. No doubt, biometrics is going to be next generation’s powerful security tool…!

What is Digital Image Processing?

                An Image may be defined as a two dimensional function f (x,y) where x and y are spatial(plane) coordinates x, y is called intensity or gray level of the image at that point. When x, y and the amplitude values of f are all finite, discrete quantities, we call the image a digital image.

                Interest in digital image areas: improvement of pictorial information for human interpretation: and representation for autonomous machine perception.

                The entire process of Image Processing and starting from the receiving of visual information to the giving out of description of the scene, may be divided into three major stages which are also considered as major sub areas, and are given below

(i) Discretization and representation: Converting visual information into a discrete form: suitable for computer processing: approximating visual information to save storage space as well as time requirement in subsequent processing.

         (ii) Processing :Improving image quality by filtering etc ; compressing data to save storage and channel capacity during transmission.

        (iii) Analysis: Extracting image features; qualifying shapes, registration and recognition.

                We concentrated on human interpretation application and developed two algorithms which can make the ATM secure by image processing.
