Today information is the most precious asset of an organization, since together with experience it represents the input necessary to make adequate decisions and consequently succeed in business. Almost all information and knowledge relating to business processes, goods and services offered by a company are processed, managed and stored through information technologies and systems, therefore information security has become increasingly important and plays a fundamental role in corporate governance. .“The term -information security- means protecting information and information systems from unauthorized access, use, disclosure, interruption, modification, or destruction” (United States Code, 2008). To ensure the identity of those attempting to access information, the concept of “Biometric Technology” has been developed in recent years. This essay will begin by explaining this concept and the characteristics of its development over time. Next, the essay will offer a brief explanation of how biometric systems work and a description of the different biometric systems developed so far. Finally, this research analyzes current and future applications and the issues surrounding it. The purpose of biometrics is to identify a person based on the measurement of their anatomical and physiological characteristics. This concept is not new, its history dates back to the 14th century, when the Chinese used footprints to identify newborns and divorce documents. In 1880, Henry Faulds, William Herschel and Francis Galton were the first to conceive the idea of ​​using biometric identification to ensure security in civilian areas, such as using fingerprints for criminal identification and fingerprinting at the core of the paper. .....M. These systems are simple and economical; however, the geometry of the hand can change and the devices for capturing images are not too small to fit on a laptop. Iris recognition is very accurate and distinctive because the iris has a complex texture capable of producing a significant amount of information to identify a person. Furthermore, the iris remains almost unchanged compared to childhood, only tiny variations are presented. Biometric data is acquired using a small high-definition camera capable of recognizing different characteristics of the iris. Furthermore, the system is able to detect the use of contact lenses with fake iris and to understand from the natural movement of the eye whether the sample object is a living being. Although iris recognition systems were initially expensive and complex to use, new technological developments have improved these weaknesses.
