Olfactory Biometric Technique: An Emerging Technology

Prathyusha Kanakam, K. C. B. Rao, S Mahaboob Hussain


Now-a-days authentication becomes a part of our daily life. Biometric authentication or, simply, biometrics refers to the method of using the physiological or behavioral characteristics to determine or verify one’s identity. Many of the systems require reliable personal recognition approaches to either identify or determine an individual by requesting their services. The purpose of such approaches is to ensure that whether the rendered services are accessed only by a legitimate user or anyone else. These methods applied for secure access of buildings, computer systems, laptops, cellular phones and ATMs. There are different types of biometric techniques exists in our literature based on the physical characteristics( such as eye’s features (Iris, retina), facial features, hand geometry, ear shape, finger prints, wrist/hand veins, DNA, chemical composition of body odor) and the personal characteristics (such as handwritten signature, keystrokes/typing patterns, voiceprint). In this paper, we presented a perspective scheme i.e., olfactory biometric technique (based on body odor) which is still under development. Odor, as a biometric technique, has some important characteristics, mainly, it is faster and easier since users will be not involved with unfamiliar interfaces such as typing password, signing or even deliberate exposing some part of the body.

Keywords: Authentication, biometrics, biometric technology, olfactory
