“…There is an upper lip (from under the nose and extending laterally toward the cheek from the nasolabial sulcus) and a lower lip (bound inferiorly by a prominent groove, the labiomental sulcus); the two lips are joined at the corners of the mouth -the comissures -and separated by the buccal fend.

Cheiloscopy is a forensic investigation technique that deals with identification of humans based on lips traces. This is unique for individuals like the finger prints. Lip prints are hereditary yet considered to be individualistic, each possessing their own unique characteristics. For this reason it is safe to suggest that lip prints can be included in the forensic sciences arena as a legitimate means of identifying persons of interest connected with criminal activity. Lip prints thus hold potential promise as an instrumental tool in forensic odontology. The purpose of this article is to give an insight into this branch of forensic odontology with an emphasis on its historical background, techniques of recording it and its future perspectives.

“…For this reason, the lip print image, I, should be enhanced and all of its artefacts removed. Many lip print feature extraction algorithms have been reported in the literature [1,[6][7][8][9][10][11][12][13]. In this paper, a new approach to lip print extraction and analysis is presented.…”

“…Some of identifiers mentioned above are captured by police technicians directly from crime scenes. Latent lip prints can be also successfully collected [9,10,11,13]. If properly captured and examined, the material left at a crime scene can contain useful data leading to personal identification.…”

“…Even though lip print analysis is not substantially developed, this new form of identification is slowly becoming accepted and being introduced into practice all over the world. Nowadays, technique of lip print image analysis can be used for human identification, for example when a post mortem identification is needed [10]. It should be emphasized that cheiloscopy has already been successfully used as an evidence in lawsuits [12,13].…”

“…This is the method of capture that we utilized during our investigations, as it allows for the lip images to capture more precise textures. These techniques have been described in a number of papers [2,[6][7][8][9][10][11][12][13]. The recognition results reported in the aforementioned papers have now been significantly improved.…”

Abstract. This paper presents a method of lip print comparison and recognition. In the first stage the appropriate lip print features are extracted. Lip prints can be captured by police departments. Traces from lips may also found at a crime scene. The approach uses the well known DTW algorithm and Copeland vote counting method. Tests were conducted on 120 lip print images. The results obtained are very promising and suggest that the proposed recognition method can be introduced into professional forensic identification systems.

Lip Prints: Admissibility of Comparison Results

Comparing the image of a human lip impressed on an object associated with a crime scene, such as a glass, paper cup, or other surface, with that of the lips of a suspect, has been asserted by crime scene investigators to offer potentially useful evidence in identifying defendants in criminal cases. Often, it has been suggested that such traces have individualization value, though little scientific research has been published on the topic. No books or scientific literature exists examining the persistence of lip creases; and there is little information to be found on how similar or different such crease markings may be among people. Nor have generally accepted examination methodologies been described and tested. Although frequently mentioned in criminal investigation books as providing valid evidence of identity, lip impressions have rarely featured in actual casework, because the technique is not one of the recognized forensic disciplines. This article discusses the only appellate court decision in a criminal case involving the admissibility of evidence of a lip print comparison; it also considers the evidentiary standard by which admissibility has been judged.
