Exam 6: Fingerprints

The number of deltas found in an arch pattern is ________ the number of deltas found in a loop pattern.

A plain arch is the simplest of all fingerprint patterns.

Four common chemical methods for visualizing latent prints are SuperGlue fuming, ninhydrin, physical developer, and ________ fuming.

After the latent print has been visualized, a photograph must be taken before any further attempts at preservation.

Prints impressed in a bar of soap are referred to as:

Match the word in Column 1 to its definition in Column 2. Each answer can only be used once. A)A class of fingerprints characterized by ridge lines that enter the print from one side and flow out the other side B)An inkless device that captures digital images of fingerprints and palm prints and electronically transmits them to an AFIS C)A square electronic dot that is used to compose a digital image D)A fingerprint impressed in a soft surface E)A class of fingerprints characterized by ridge lines that enter from one side of the pattern and curve around to exit from the same side of the pattern F)A system of identification of individuals by measurement of parts of the body, developed by Alphonse Bertillon G)A process through which a picture is converted into pixels H)A technique for visualizing latent fingerprints by exposing them to iodine vapors I)Ridge endings, bifurcations, enclosures, and other ridge details which must match in two fingerprints to establish their common origin J)A chemical reagent used to develop latent fingerprints on porous materials by reacting with amino acids in perspiration K)A class of fingerprints that includes ridge patterns that are generally rounded or circular and have two deltas L)A physical change from the solid directly into the gaseous state M)A fingerprint made by the deposit of oils and/or perspiration; it is invisible to the naked eye N)A silver nitrate-based reagent formulated to develop latent fingerprints on porous surfaces O)To emit visible light when exposed to light of a shorter wavelength P)A technique for visualizing latent fingerprints on nonporous surfaces by exposing them to cyanoacrylate vapors Q)A fingerprint made when the finger deposits a visible material such as ink, dirt, or blood onto a surface R)A verbal description of a perpetrator's physical characteristics and dress provided by an eyewitness -Digital imaging

The analysis, comparison, evaluation, and verification of a fingerprint is known as ________.

The presence or absence of the ________ pattern is the basis for determination of the primary classification.

What is the difference between a visible, plastic, and latent fingerprint? What are three techniques that could be used to develop latent fingerprints?

Which substance is a substitute for Ninhydrin?

In the Primary Classification scheme, the left index finger has a potential value of:

The comparison step of the ACE-V process requires the comparison of the known and unknown print at two different levels.

Compare and contrast anthropometry and fingerprinting as means of identification. Why do we use fingerprints today instead of anthropometry?

A latent fingerprint is a fingerprint made by the deposit of oils and/or perspiration that is visible to the naked eye.

The perspiration in fingerprints contains a variety of components that fluoresce when illuminated by laser light.

Dermal papillae are cells that form a ________ between the outer skin, or epidermis, and the inner skin, or the dermis.

It is possible to obscure one's fingerprints by scarring.

Loops include ridge patterns that are generally rounded or circular and have two deltas.

The FBI's IAFIS became fully operational in:
