# Cancellable-Template Understanding and Implementing Cancellable Templates in Biometrics for privacy protection <b>Implemented minutiae extraction from the finger print image. </b> Steps involved 1. Image thinning. 2. Detection of the ridges and bifurcations. 3. Plotting the (x,y) coordinates which contains the minutiae points. <b> Transform input image to black and white image. </b>  <b> Image thinning - Convert input image to thin image. </b>  <b> Detecting the bifurcations and ridges. </b> <b> Bifurcation Points </b>  <b> Minutiae Points </b>  <b> Converting coordinates to csv for processing </b> Get the respective (x,y) coordinates for the corresponding ridges and bifurcation points (minutiae) and store it in a csv / array. Coordinates of minutiae points are stored in an 1-D array and the corresponding line graph is plotted to visualize the points.  <b> Cancellable Template implementation (POC) : Method 1 </b> Proposed Method : 1 1. Distance calculation between the minutiae coordinates using neo4j graph database. 2. Implementing reverse tranformation logic. Implemented: 1. Choose a reference point in the list of minutiae. 2. Find the distance from the reference minutiae to all other minutiae points.
