Fingerprint
* Most fingerprints have patterns of ridges separated by valleys.
* Some fingerprints have loops, others whorls, and some arches.
  * are used for the first time to prove identity. William Herschel, Indian Civil service, used Rajyadhar Konai's print on the back of an envelope.
* are a classic biometric
  - part of the pre-employment process
  - an ideal adhesive for foreign matter
  - biometric identification
  - excellent for trace evidence and determining identity
  - hazardous to old pewter pieces if touched before completely dry
  - impressions created by ridges on the skin
* are located in fingers
  - fridges
  - marking
* are one of the characteristics that vary from person to person
  - many by-products of the human evolutionary cycle
  - most effective tools for locating a missing person
  - part of fingers
  - specific external features
  - the basis for criminal history foundation at every police agency on earth
* are the most reliable method of identification because each person's prints are unique
  - useful and quickest way to identify bodies
  - only positive means of identification
  - two-dimensional representations of the physical attributes of our fingertips
* can cause data loss
  - read errors
  - distort the laser beam and adversely affect performance
  - encode protein folds and functionalities more effectively than single motifs
* carry a limited amount of data that do little more than help to identify individuals
  - stigma because of their longtime association with cops booking suspects
* come into the hands of law enforcement agencies from many legitimate sources.
* contain acids
  - patterns that can help detectives narrow a list of suspects
* demonstrate both the uniqueness and commonalities found in humans.
* have applications in security as well as filesystem replication
  - various means of comparison
* is identity verification
  - one of the earliest forms of scientific evidence to be recognized by courts of law
  - the oldest of the biometric technologies in use
* make it possible for investigators to solve crimes.
* occur because glands in our hands and feet secret liquids, mainly sweat and oils.
* offer a reliable means of personal identification
  - an infallible means of personal identification
* provide an additional source of identification of a located child.
* remain permanent as an infant grows into an adult.
* serve a function - they provide traction for the fingers to grasp things.
* typically consist of hundreds or even thousands of bits.
* uses conserved motifs to characterise particular folds and functionalities.
* vary on many different dimensions, one of which is called ridgecount.
+ Fingerprint scanner: Computer hardware :: Data input :: Machines :: Authentication methods
  * Every person has marks on his or hers fingers. They can not be removed or changed. These marks have a pattern and this pattern is called the fingerprint. Every fingerprint is special, and different from any other in the world. Because there are countless combinations, fingerprints have become an ideal means of identification.

### fingerprint:

Fingerprint authentication
* is still the most popular form of biometrics.
* reduces password administration while enhancing security.

### fire conditions:

Drought condition
* are fire conditions
  - hard on banana plants
* can also impact adult pecan weevil emergence
  - have impact
* cause the ponds in which the ferns live to dry up much earlier than usual.
* do influence the occurrence of forest fire events in the southwest.
* have differing impacts on the community during different times of the year.
* result in less water in the soil.
* retard the winter breeding season and almost eliminate late spring breeding.
* stress the oat plants and it becomes much more toxic.
* tend to decrease the percent of adult females that breed in a given year.
