India. Assistant professor, Amity Institute of Forensic Science, Amity University, Noida, U.P. India Abstract:-Personal authentication is the key of security and reliability in society. The reliability of personal identification using palm print is an equal and valuable evidence as the fingerprints which is commonly used modalities. The latent prints which are encountered at scene of crime (suicide notes) or in form of the questioned documents such as wills, property documents, official papers etc. The development of these latent palm prints not only gives the conclusive identification of the individual, but also provides the unique minutiae details for authentication. In this study, 40 samples (both male and female) from North part of India were taken to establish the identification of an individual through the development of latent palm prints present on documents. The obtained 12 parameters from this study not only increase the evidential value of such lateral palm prints, it can also be placed at par with the fingerprints in court of law on the top of all other scientific evidences. Key Words: Personal Identification, Questioned documents, evidential value, lateral palm prints. I. INTRODUCTION t has been noted that Palm prints (Wen Xin Li & et al. 2002) and fingerprints are equally valuable evidence. In forensic application the evidential value of palm print (You Jane & et al. 2002) is clear as about 30 percent of the latent recovered from crime scenes ( Anil K. Jain & et al. 2009) are from palms, and play an important role in the identification (Naidu Swati & et al. 2011) of an individual. The ridges are studded with sweat pores which secrete sweat. However, it must be remembered that while writing or preparing the works of art, etc. one cannot help touching or holding the surface or part of the hand (Palm and Finger) resting on the writing surface to give support and facilitating the movement of the hand. Since the finger/Palm has raised lines and furrows having sweat pores which keeps the ridges moist, and hence as it touches the writing surface, it is expected to leave their impression (prints) on the writing surface or papers. Especially when we signed, the lower part of the palm (Hypothenar area) comes in the contact of the surface. Since sweat is apparently a colorless fluid, the prints so left behind are not visible to the naked eye; the visibility of the prints (Kumar Shen & et al. 2002) are enhanced by various methods which then can be compared with the specimen obtained from the suspects to fix identity. In this study, the inherent relation of the signatures with the lateral palm prints leading the identification of individual, and also increasing the reliability of questioned documents examination. The fresh and old samples were taken to see the occurrence of latent palm prints, and are they identifiable or not? By studying the developed palm prints and obtained 12 parameters from the fresh and old samples of minutiae details, it was noticed that the identification of subject is possible. Although the natural variation occurs because, (a human is not a machine who can work similar) but gives the authenticity of an individual. II. MATERIAL AND METHODS Samples Total number of subjects (40), including 20 male and 20 female (age group 15- 50 yrs.) from the villages of Uttar pradesh such as; Ramala, Budhpur, Kishanpur Baral, Baoli, Bijwara, Barout, and Sarurpur from Districts Baghpat and Meerut (North part of India) were randomly selected for this study, The old print was taken in October 2012 while the fresh samples were taken in March 2013 (Chaudhary R.& et al.2004). All the samples were taken on the white paper sheet written by blue ball pen. For the development of latent palm prints, the Black powder was used for fresh samples, while for the development of old prints Ninhydrin was used (easily available, and Frequently used for development of old latent prints). Methods The selection criteria of all individuals were random, and the consent was taken. The details about the individual such as Age, sex, Address, occupation and their educational qualification were noticed. The subjects were asked to sit on the chair at ease. After giving a blank white paper sheet and blue ball pen to the individuals were asked to sit on a chair and to put the paper on a table which was up to the height of elbow. Then the individuals were spoke to put their I
