Personal Computer Security & Iris Technology
This is an excerpt from the paper...
Today, organizations around the world depend on computers and other electronic devices to keep their operations running 24 hours a day, seven days a week. Businesses provide employees with computers the size of notebooks that have more processing power than the room-sized computers that controlled the Apollo moon program, and cellular phones ensure that no one ever needs to be truly unreachable. Unfortunately, the same devices that enable this 24/7 world also make businesses, governments and other institutions more vulnerable to sabotage and outright theft than at any time in the past. Thieves no longer have to be physically located within a building to gain access to sensitive information. The loss of information from the theft of a notebook computer from an airport waiting lounge can prove devastating. Business, government, and other institutions have long recognized the need to secure electronic devices both to protect against external theft and sabotage, and to prevent internal breaches of security. But always security effectiveness must be measured against its cost, ease of use, and the likelihood that it will be used. This research examines the importance of security authorization for electronic devices, evaluates common ways in which security is provided, introduces biometric security authentication, and provides an in-depth examination of iris technology as used with personal computers.IMPORTANCE AND TYPES OF COMPUTER SECURITY

There are, however, drawbacks to fingerprint scans. To begin with, although fingerprint scans are highly accurate, the technology does not actually store the scan itself. Instead, it stores metadata about the enrollment scan and uses that to compare to the real-time authentication scan. This is in contrast to iris technology where the actual scan is stored in the database. Although the difference is slight, iris technology generally has a higher accuracy rate. In addition, iris technology has the significant advantage of being hands-free, making it ideal for business and institutional environments where users are likely to have difficulty in free their hands for a fingerprint scan (Fenner 56).
When iris scans are used to gain access to computers, the user looks into a camera from a distance of approximately 18 inches. This makes the technology ideal for office and technical environments where workers may be housed in cubicles or other relatively confined areas. Users can be wearing a mask or gloves·as is likely in medical environments·and still use the devices successfully. As with fingerprint scans, the information retrieved in real-time is compared to information stored in a database (Consta
