Abstract

A method of verifying a carved seal includes detecting a pressure on a carved seal stamp is detected through pins extending from a face of the carved stamp steal. It is determined if the pressure indicates that the seal is being pressed. A fingerprint of a user of the seal is read when it is determined that the seal is being pressed. An image of an object being stamped by the seal is photographed if the pressure indicates that the seal is being pressed. A time that the seal is being pressed is determined if the pressure indicates that the seal is being pressed. A location of the seal is determined if the pressure indicates that the seal is being pressed. An audio note is recorded if the pressure indicates that the seal is being pressed. The fingerprint, time, and location is associated with the photograph of the image of the object being stamped by the seal. The information is encoded into a face of the seal to indicate that the fingerprint was determined to belong to an authorized user.
