Computer accessories are used in biometrics systems to interpret the physical characteristics of people. Something inherent in each individual and not transferable to access systems or locations without the person having to remember passwords or carry cards embedded chips that can be stolen, copied or lost. These systems are composed of a biometric device that captures the physical features of the person and a biometric software that analyzes and processes to verify that the individual is who he claims to be. safety, convenience and speed are three characteristic features of biometric security are accelerating the adoption of these systems in pursuit of total security. Typically, these biometrics are based on the characteristics of the iris, face, voice, hand or fingerprints. a The most common biometric device is currently the fingerprint reader (fingerprint reader) because these can be also as an accessory will manage PC, which when connected to USB port of the computer and then install the software that usually comes with the reader, allows for example, replacing the Windows password for the user’s fingerprint or encrypt files using the fingerprint as the key. Several devices are fingerprint readers, when I recommend choosing one and endless Software included with the reader, which with its characteristics of strength, durability, small size, false finger sensor detector and efficiency with all type of tracks, make it a good choice for any office environment both in and outdoors.
a The main use of biometric systems is the control of persons, whether in income, the shift within the company through checkpoints or in the output. There are a variety of biometric solutions: control assistance (replacing clocks), intermediate checkpoints in sensitive areas of an organization, identification (for clubs and libraries), personal identification to prove his identity as a means for authorizing procedures and formalities. An example of a biometric system is the software functional i-Footprints for access control and personal assistance, which is based on a reading fingerprints. There is a new trend towards devices that do not involve contact with the biometric device by the user, to prevent failures due to wear or dirt and make the process more friendly. In this sense facial recognition technology is gaining ground, and that using a web camera and biometric capture device and software capable of detecting the features of the face, it becomes a great alternative to conventional systems, due to low cost of implementation and maintenance, as well as its greater acceptance among users because they are already familiar with web cameras through chat programs and social networks. He uses this system of recognition and identification of face to perform access control and personal assistance. Biometric Another use of facial recognition system is to detect user moods and according to it, perform some action, such as the new patent from Sony, you choose a song within a play-list line the detected mood.
We can communicate through codes as do the young people in the chat, stay anonymous behind a computer screen and under a pseudo name, but not forever. Sooner or later, we must rid ourselves of the masks and host of neighbor in our hearts, not our meeting rooms. Today, the youth does not need lengthy letters, placed in envelopes with stamps. a stas have been replaced by the screen and keyboard, or cell phone. From an early age, children learn to use instant messaging software like Yahoo, MSN, ICQ or Skype. Existing applications are freely available, easy and fast.
The Internet enables them to cross the barriers of time and space, allowing access to any part of the planet, though confined to their personal computers or mobile phones. This makes them de facto pragmatic people, but distant, as the technology they use. But Are online communications that alienate us, or is our alienation what motivates us to develop this type of communication? What happens to a generation that knows no other way to connect than through cable or wireless? Everything is connected to a child, I never dreamed that we saw device in science fiction were to become everyday tools at an early age. Small, if we wanted to play with friends, we used an old tool called "feet." We walked to their houses to talk. For formalism, usually were the mothers of my friends with whom I should talk first. Today, we can send messages to our friends instantly using mobile phones.
