In addition to the neurological and behavioral consequences of methamphetamine abuse, long-term users also suffer physical effects, including weight loss, severe tooth decay and tooth loss (âmeth mouthâ), and skin sores.
(The term biometrics is derived from the Greek words bio meaning life and metric meaning to measure.) There are two main types of biometric identifiers: Physiological characteristics: The shape or composition of the body. Behavioral characteristics: The behavior of a person. Examples of physiological characteristics used for biometric authentication include fingerprints; DNA; face, hand, retina or ear features; and odor.
To fix that problem, biometrics security system can be applied. The most use of biometrics security system in network is the logical access control method. It will verify person's identification for secure workstation logon or network logon to get access control to the system [Reid, 2011] .or example, users can share their fingerprints, iris and so forth allowing other users access to secure information. Each trait used during identification is a single property of that user. In other words, it is extremely hard or impossible to make duplicate or share biometrics accessing data with other users.
