A method and apparatus for populating a form with data is described. In one embodiment of the invention, a form is displayed to the user via the target application. Each form has one or more data receptacles. The data receptacles of a form are filled with data when the user executes a data population command. The form completion program executes the data population command when a graphical representation of a particular data set is placed over the form. Each data set is stored in an encrypted manner and is accessible to users who enter the appropriate information into an authentication mechanism. To populate a form with data the form completion program obtains an image of the form and then searches for a template file that resembles the form image to within a certain threshold. The template files are typically stored on the computer hosting the target application in a template directory that is arranged according to a predefined structure. The form completion program is configured to search for templates that resemble the form image in the template directory to within a certain threshold.
