Clearly defining your workflow and specifying your system requirements will ensure you get the Automated Fingerprint Identification System your agency needs.
Police departments in seven Indian states have solved more than 500 crimes with a biometric system that links fingerprint and palmprint collection at crime scenes with district databases in real-time, providing almost instantaneous biometric matching and identification results.
A study on the effects of time and temperature on the recovery of latent prints from computer paper and plastic bottles.
This article will discuss how equipment can influence the design and infrastructural needs of two laboratory space types where the identification of evidence takes place.
Biometrics technology has matured, offering some exciting new forensic products—and promising revolutionary innovations in the near future.
Although the process is time consuming, using Physical Developer when other methods have failed could be the factor that helps solve a case.
Enhancing Latent Prints

Old technique (iodine fuming) plus new technology (digital subtraction) equals more options for the development and enhancement of latent fingerprints. The use of iodine fumes to locate latent fingerprints has been available to criminalists for years. Iodine fumes react with sebaceous materials in a fingerprint in a reversible physical process that does not alter or interfere with the subsequent application of other development techniques such as 1,2 Indanedione, Ninhy-drin, DFO, etc.

Friction ridge skin – raised layers of skin with openings for sweat glands – covers the palms of the hands and soles of the feet. The stable and complex characteristics of friction ridges enable a form of identification that law enforcement has used for over a century.
The enhancement of latent fingerprints from human skin continues to be a problem for forensic laboratories. Pig skin is closely related to human skin in thickness, basal cell density, collagen fibers, vascular supply, subcutaneous fat, sweat glands, color, and hair follicles.
