In addition to using the dustpan pattern and bucket pattern to classify fingerprints, they also use the sparseness and density of the patterns to determine the age of the fingerprint owner - the fingerprints of adults are denser than those of teenagers. Therefore, fingerprints became an important form of identity proof for the ancients. To identify the owner of a fingerprint, one only needed to ask the "owner" to press the fingerprint again and then compare it with the existing fingerprint under the sun.
