ABSTRACT

The review article "Persistence of fingerprint in adverse environmental conditions like temperature, humidity, change of surface" presents different types of fingerprints and its persistence under different environmental conditions. Fingerprint is an individual characteristic and are among the earliest and most common forensic evidence to be employed for individual identification. According to the report of the Central Bureau of Investigation, 'fingerprint identification is the most promising method of identification on an individual basis which is founded on the exclusive and repetitive pattern of the ridge details found on the fingertip the most common prints found at the crime scene are the latent prints.". They are not visible prints retained on a substrate due to various bodily secretions."

Fingerprints can be deposited on a variety of substrates, which are typically categorized as porous, non-porous, and semi-porous surfaces. Non-porous surfaces typically are non-absorbent, and therefore the quickly deposited fingerprint residue would be more likely to be eliminated. Prints were deposited on the surfaces as mentioned. Natural prints were impressed on the substrates without pre-hand-washing or post eccrine (wearing gloves) or sebaceous (rubbing fingers on the nose) print grooming. Normal fingerprint is a distinct pattern unlike any other. Fingerprints are the oldest biometric identification method for human beings and have been utilized in China to verify legal documents for three thousand years. Non-porous smooth surfaces consist of glass, metal, and plastic.
