They also found that there has been no adequate study on the effects of ageing and facial recognition. Despite these concerns, the report did acknowledge that biometric facial scanning was suitable for use when verifying photo documents, given that the preconditions, such as controlled ambient lighting, are met (cf. An investigation into the performance of facial recognition systems relative to their planned use in photo identification documents - BioP I, 2004).
III. Viability for Use in Large-Scale Venues
The success of facial recognition technology for wide-scale security augmentation is hindered by the inherent limitations of current technology, as well as environmental and physiological factors. Given that venues for major sporting events traditionally have security measures already in place, such as video surveillance and gated access, facial recognition technology might be useful in augmenting other, more traditional forms of security. For facial recognition to be successfully implemented, it is necessary to capture facial images when visitors go through gated areas, and then compare that image against government databases. There are, however, severe limitations with this type of electronic surveillance, since for accurate scanning, visitors must look directly into a camera, not be wearing any articles of clothing that might obstruct facial features (such as hats or glasses), and ambient lighting must be controlled. Additionally, facial recognition technology can only provide warning for people who have photographic records in government databases; as...
Furthermore, in order to increase the accuracy of the technology, security personnel must be able to maximize control of the environment, as well as the subject. Lastly, it should be noted that, due to technological limitations, "performing facial recognition processes with relatively high fidelity and at long distances remains technically challenging for automated systems" (John D. Woodward et al., 2003, p. 12); therefore, facial recognition must be implemented at points of entry into the stadium, and even then will only have limited success, due to the myriad constraints on the technology, as well as the environmental preconditions that must be met to ensure accuracy.

As a result, it can be said that the workplace of the modern world has changed beyond recognition with the revolution brought by the technological advancements. The technological transformation in the last two decades has been drastic and this trend will continue for the next many decades as robots are increasing replacing jobs that require the engagement of repetitive, customized actions. There are a number of jobs that are at
127, 2005). An Eigenface representation (Carts-Power, pg. 127, 2005) created using primary "components" (Carts-Power, pg. 127, 2005) of the covariance matrix of a training set of facial images (Carts-Power, pg. 127, 2005). This method converts the facial data into eigenvectors projected into Eigenspace (a subspace), (Carts-Power, pg. 127, 2005) allowing copious "data compression because surprisingly few Eigenvector terms are needed to give a fair likeness of most faces. The method
Technology: The Silent Killer Introduction In the relentless march of technological advancement, we have become engrossed in a world where devices and digital screens dominate our daily lives. While technology has undeniably enriched our lives in many ways, it is equally important to acknowledge its pernicious impact on our physical and mental well-being. From the sedentary lifestyles it promotes to the constant bombardment of information it provides, technology is taking a toll on
Evidence-Based Project Proposal Graduate Project in Nursing The incidence of sexually transmitted diseases has been increasing among adolescents in countries around the world, but there remains a dearth of timely and relevant studies concerning salient differences in knowledge level and attitudes between different cultures and ethnic populations. One common factor that has been consistently demonstrated in improving the effectiveness of treatments for sexually transmitted diseases is promoting adherence to treatment regimens, most
Biometric Technology Biometrics are those easily measurable physiological, behavioral or anatomical characteristics, which can be used in identifying an individual. A common biometric modality is fingerprints, but there are others like DNA, voice patterns, irises, facial patterns, and palm prints. Biometrics have been quite beneficial in the last couple of years for law enforcement and intelligence (investigative) purposes, mostly to the FBI and its associates. in the intelligence and law enforcement
Fingerprints Improving the Science of Fingerprinting: A Literature Review Fingerprints are one of the most commonly employed tools that we have in investigating crime. This powerful forensics methodology has contributed to the solving of countless criminal cases and has been used as convicting evidence in courts of law. However, as this literature review shows, even the use of fingerprints is in a state of evolution as we gain ever greater and more
