1. A method for registering a fingerprint of a user through an electronic device, comprising:
sensing a fingerprint input into a fingerprint recognition area formed on a display module of the electronic device to capture at least one image of the fingerprint input;
determining characteristics of the fingerprint input based on the at least one image of the fingerprint input when the fingerprint input is a rolled fingerprint; and
storing the at least one image of the fingerprint input and the characteristics of the fingerprint input as personalized information of the user,
wherein when the fingerprint recognition area is formed on a partial area of the display module,
the determining of the characteristics of the fingerprint input comprises:
determining an initial time for the fingerprint input in the partial area;
determining a direction of the rolled fingerprint based on the initial time for the fingerprint input;
determining a final time for the fingerprint input in the partial area after the direction in which the rolled fingerprint has been determined;
determining a total time required for the fingerprint input based on the initial time and the final time; and
setting the direction of the rolled fingerprint and the total time required for the fingerprint input as the characteristics of the fingerprint input.
