The FBI’s BCOE – located in Clarksburg, West Virginia – is the FBI’s program for exploring and advancing the use of new and enhanced biometric technologies and capabilities for integration into operations. Every day, the BCOE strives to deliver state-of-the-art biometric tools and technologies to law enforcement and intelligence personnel working in communities around the world.
Modalities (particular methods or procedures):
facial recognition 
voice recognition
palm print 
fingerprint
Iris scan 
DNA
Commonly implemented or studied biometric modalities include fingerprint, face, iris, voice, hand writer recognition, and hand geometry. There is not one biometric modality that is best for all implementations, and many factors must be taken into account when implementing a biometric device, including location, security risks, task (identification or verification), expected number of users, user circumstances, existing data, etc.
A facial recognition is an image of a suspect’s face, as described by an eye-witness of a crime. In the past, law enforces had to use artists to draw or paint the witness’s description of a suspect. Nowadays, the job can be done by computer. Many English-speaking countries use a softwa.re package called EFIT (Electronic Facial Identification Technique). It has a large database of different facial types from different races and ethnicities. A trained operator can use the system to produce an accurate facial composite based on a witness description. EFIT is unique because it also recognizes and includes the psychological factors that affect our ability to recognize and remember faces.
DNA standsfor deoxyribonucleic acid. DNA is genetic material in human cells – and the cells of all living organisms. It is present in every cell in the human body, and a person’s DNA is the same in every cell: the DNA in a person’s blood is the same as the DNA in his skin cells, saliva, and other biological material.
PROJECT WORK
Ø Read the text and learn the forensic terms by heart.
Ø Search the Internet and find out the images of described pieces of forensic equipment. Present them in class.
Ø What do you know about the following founding scientists? Match the scientists and their discoveries. Make a presentation about one of them.
| 1. Mathieu Orfila (1787-1853) | A. First to look into fingerprinting |
| 2. Alphonse Bertillon (1853-1914) | B. First to refine the science of bullet comparison |
| 3. Francis Galton (1822-1911) | C. Father of toxicology |
| 4. Calvin Goddard (1891-1955) | D. Authority on authenticating documents |
| 5. Albert Osborn (1858-1946) | E. Developed the science of anthropometry |
