The Trilogy of Dactylography, Cheiloscopy and Bloodgroups- A Futuristic AID in Forensic Investigations
Personal Identification is of paramount importance not only in legal medicine but also in medico-legal investigation and genetic research. Identification means the determination of the individuality of a person. The use of prints as a mean of personal identification is one of the common methods in forensic anthropology and the most popular prints are fingerprints and lip prints, which are normal lines and fissures in the form of wrinkles and grooves present in the zone of transition of human lip.

Several studies have been carried out in these regard with most of the studies showing a significant co relationship between the fingerprints and the blood group with only handful of studies showing co relationship among fingerprints, lip prints and blood group. The pattern of fingerprints and lip prints were shown to be stable relative to surrounding anatomy and with passage of time and also in its easiest way of recording and documentation.1
Lip prints and fingerprints are frequently encountered in medico legal investigations and in Forensic science laboratories as important form of transfer evidences. Blood itself is an extremely important entity in the medico legal practice, which alone or along with other the prints can play a clinching role to unfold different criminal problems.2
