Myth of the Day

Digital enhancement of a fingerprint image can accidentally morph the fingerprint of one person into that of another.
Category: All DME Myths
When digital image enhancement is performed according to accepted guidelines and standards, it is not possible to change one person’s fingerprint into another’s. The end result of properly enhancing any image is an increase in the visibility of characteristics of interest within the image. Research completed at Indiana University Purdue University Indianapolis (IUPUI), Mathematical Sciences Department, found that the possibility of such an occurrence to be one in 10 to the 80th power (i.e., 1 followed by 80 zeroes). This number is approximately equal to the number of atoms in the universe.
