In today's ever changing world security is one of the main issues that both organisations and authorities have to look at in a more effective manner. The new wave of crime does not come from people wielding guns and wearing masks, it comes from the attainment of valuable information and getting into areas which they are not permitted to enter. Only recently there have been two large robberies in Heathrow Airport where people appeared to be able to get to a restricted area and know exactly where to be to make an easy theft and getaway. In organisations there can be a high level of fraud and leaking of vital information, the fraud can be just something as simple as the amount of hours people say they have worked and the true amount. For example in a large organisation with many employees carrying on in this manner it could cost the organisation a large amount of money each year, when organisations are trying to reduce costs. The whole new idea of Biometrics can allow organisations to have a better control of what the employees are doing and how long they are actually working. It will also cut down on the accessibility to secure areas. Most people only associate Biometrics with what they have seen in films like Mission Impossible and do not consider it as readily available as it actually is and the functions that are available to an organisation. This dissertation will compare the most widely forms of security being used at present and details of the different options within Biometrics that can be used to improve security for today's world. This will include, fingerprint verification, facial scanning technology, speech verification, retinal and iris scanning. The aim is to show all the available features of a Biometric system, once all the information is sourced an organisation will have to decide on which option to implement. An investment in a security system is similar to any new project put before a decision making committee, this can be a hard sale to make to them but with the nature of today' s business it is an investment that should be made. Finally within the dissertation there will be the area of privacy and confidentiality. Due to the nature of Biometrics using personal attributes or characteristics there will be legal issues that will have to be overcome to allow Biometrics to become a part of the everyday life just as passwords and swipe cards are today.
