What is automated minutiae mapping?

Back

Automated minutiae mapping is a technology used in fingerprint analysis that identifies and maps the unique features (minutiae) of fingerprints, allowing for faster and more objective comparisons.

What is iodine fuming in fingerprint development?

Back

Iodine fuming is a fingerprint development method that produces temporary brown prints on surfaces, which must be photographed quickly before they fade.

What is the purpose of ninhydrin in fingerprint development?

Back

Ninhydrin is a chemical used to develop fingerprints on porous surfaces by reacting with amino acids in sweat to produce a colored compound.

Front

What is cyanoacrylate fuming?

Back

Cyanoacrylate fuming, also known as superglue fuming, is a fingerprint development technique that uses cyanoacrylate vapor to visualize fingerprints on non-porous surfaces.

Front

What is the significance of minutiae in fingerprint analysis?

Back

Minutiae are the unique features of fingerprints, such as ridge endings and bifurcations, that are used to compare and identify fingerprints.
