analyzing and interpreting data. My lesson was structured to help students engage in these practices because I had discussion questions written in advance‚ the students created their own individual fingerprinting model‚ the students analyzed their fingerprints‚ and interpreted the information they learned further with more activities. I wrote several discussion questions to ask the students for every section of the lesson and made sure to have the lesson with me while I taught so I was able to refer

police official was the first person to keep fingerprint files. He classified fingerprints according to a system established by Sir Francis Galton‚ an anthropologist related to Charles Darwin. Galton later published a book‚ Fingerprints‚ that contained a classification system. His discovery that no two individuals share the same fingerprint‚ and his classification of the details of an individual’s fingerprint are largely used today. By the 1920s‚ fingerprint identification was used by law enforcement

University of Phoenix Abstract Technologies have developed specifically for law enforcement. In the late 1800’s the first case was solved with fingerprint recognition. This happened slowly‚ following ridge lines in a single print‚ identifying it to one suspect. Today officers can search millions of fingerprints in seconds with the Automated Fingerprint Identification System (AFIS). Technologies have also went portable with the installation of Mobile Data Terminals (MDT) in many police vehicles

Fingerprinting What is it? A fingerprint is an impression of the ridges on a person’s finger. By inking a person’s finger‚ these can be recorded on paper and compared with fingerprints left at the crime scene. Since no two fingerprints are the same‚ this is a valuable way of identifying a person. Fingerprints are formed in full detail before birth and remain unchanged throughout life unless they are affected by a deep seated injury. It was in 1860 that the use of fingerprints as a reliable means of individual

These databases do things that humans wouldn’t be able to do or wouldn’t have the time to do. Two specific types of databases are AFIS and Iris scan. AFIS (also known as IAFIS) stands for Automated Fingerprint Identification System. AFIS is just that‚ a database created to keep track of fingerprints. Iris scan is the scanning of the iris as a method to identify people based on unique patterns within the ring-shaped region surrounding the pupil of the eye. Even though we use technology every day
