Authentication: This involves the prevention of unauthorized access to computer systems. Authentication takes a variety of forms, ranging from verifying account credentials to physical identity .verification to identify that the client system from which a user is attempting to connect to a server is really the authorized client system.

Encryption: This is defined as the transformation of plaintext (readable data) into ciphertext (unreadable data) by cryptographic techniques. Encryption is currently considered to be the only sure way of protecting data from disclosure during network transmissions. Encryption can be implemented with either hardware or software. Software-based encryption is the least expensive method and is suitable for applications involving low-volume transmissions; the use of software for large volumes of data results in an unacceptable increase in processing costs. Because there is no overhead associated with hardware encryption, this method is preferred when large volumes of data are involved.

BIOMETRIC IMPLEMENTATION

A biometric is an automated method of recognizing an individual based on measurable biological (anatomical and physiological) and behavioral characteristics. Biometrics is typically collected using a device called a sensor. These sensors are used to acquire the data needed for recognition and to convert the data to a digital form.

Why Biometric?

Biometric Access Control is becoming a more popular method of site security. Using fingerprints and other biometrics such as iris and voice recognition can make monitoring who is and isn't on site, where they are and what they are trying to do much easier. Because of the constant improvements in the technology, biometric access control systems are getting better and better, and are now more appropriate for a wider range of environments.

Biometric Access Control:

• Can prevent unauthorized access and exit from a building or part of a building. This can be useful in offices, factories schools, hospitals and other places where only authorized people should have access to certain areas.
• Is cost effective as it is extremely accurate and reliable, and can free up other resources such as security guards, and other staff. This means that each member of staff can get on with their own duties.
• Systems can prevent theft as only authorized people will be allowed access to restricted areas such as stock rooms, production lines, and warehouses. If there is suspicious activity, it will be much easier to investigate.
• Can prevent time and attendance fraud, as there is no chance of colleagues signing in, or swiping in for each other.
• Can make extremely busy areas such as construction sites where there are lots of different people on site much easier to manage, as only authorized people can gain access. This can help to prevent both organized and opportunistic theft and other criminal activity.
• Can help to reassure staff and visitors, that the company takes security seriously. For example, many nurseries are using Biometrics so that unauthorized people are not able to access the premises.
• It is highly beneficial as part of airport security. Restricting access to parts of the airport can help to ensure that there are no security breaches from staff, or contract workers, and that passengers can't gain access to areas where they are not allowed to be.
• It is suitable addition to the security for companies or people working with sensitive data or products. Those who handle medical records, government data, or customer data as well as other information, will need to ensure the safety of the data. By using a Biometric Access Control the data cannot be accessed by those who are not authorized to view it.
• Can be used to protect data on the move too. Mobile computing and working remotely have revolutionized the modern work environment. As more people are working on the move, or from home, the same stringent security and safety measures for data protection and site access need to be adhered to.
• Is extremely effective and can't be "beaten". Colleagues can't use the same swipe card or share pin numbers, either to gain access to the building, or to fraudulently claim they are working when they aren't even on site. It's now possible to know exactly who is in the restricted area, and who isn't. It's also less disruptive than having to sign in, or remember a pin number, or wearing an ID card.
