In today's world the life is very fast we want to do everything so quickly and easily without putting much physical and mental effort. With the advancement of technology, we are provided with higher level of knowledge through the invention of different devices. However, each technological innovation has its pros and cons. One of the emerging usages for biometric security system is in smartphones and computers that we are using today. Also, today we cannot think of living without smart phones and devices as they have become a vital part of our life. We depend on our phone and laptops for so many things during our daily activities like paying bills, connecting with friends, office work and making money transactions. But using the traditional security features we cannot get appropriate security as anyone who knows the password to unlock someone else’s phone can get access to the phone. Using biometrics traits like fingerprint, voice, face, and iris makes it more difficult to get access to the device. In this paper, I will focus on how biometrics help …show more content…
To use one, you simply place your hand on a flat surface, aligning your fingers against several pegs to ensure an accurate reading. Then, a camera takes one or more pictures of your hand and the shadow it casts. It uses this information to determine the length, width, thickness and curvature of your hand or fingers. It translates that information into a numerical template. Hand and finger geometry systems have a few strengths and weaknesses. Since hands and fingers are less distinctive than fingerprints or irises, some people are less likely to feel that the system invades their privacy. However, many people's hands change over time due to injury, changes in weight or arthritis. Some systems update the data to reflect minor changes from day to day. For higher-security applications, biometric systems use more unique characteristics, like
