JAVA RING

Computer Engineering electronics Engineering Civil Engineering

Password is a common mean of implementing security. Dallas Semiconductor has developed a new Java-based, computerized ring that will automatically unlock doors and log on to computers. This java based technique overcomes the deficiencies of the secret password. A Java Ring is a finger ring that contains a small microprocessor which runs JVM and is preloaded with applets. The jewel of Java Ring is Java iButton, which is a microchip enclosed in a secure package. There are many technologies similar to iButton. But there is no match for this technology. A Java Ring goes beyond a traditional smart card by providing real memory, more power, and a capacity for dynamic programming. iButtons have an advantage over smart cards in term of durability and longevity. There are different kinds of iButtons of which cryptographic iButtons require a special mention. Information is transferred between iButton and PC by means of blue dot receptor. A layer of software called TMEX is needed to interface iButtons to PCs and produce the desired information in the desired format. They find much applications in authentication and auditing trails. With a significant market penetration of 20 billion iButtons, we can expect an exponential growth in this technology. These devices will surely revolutionize the way we look at future. It seems that everything we access today is under lock and key. Even the devices we use are protected by passwords. It can be frustrating trying to keep with all of the passwords and keys needed to access any door or computer program. Dallas Semiconductor is developing a new Java-based, computerized ring that will automatically unlock doors and log on to computers. This mobile computer can become even more secure. You can keep the iButton with you wherever you go by wearing it as a closely guarded accessory - a watch, a key chain, a wallet, a ring - something you have spend your entire life practising how not to lose. Here are a few reasons why you might want to wear the iButton in the accessory that best fits your life style : w It is a safe place to keep the private keys to conduct transactions. w It overcomes the deficiencies of the secret password. w You eliminate keystroke with a quick, intentional press of the Blue Dot. w You keep your computer at hand versus lugging your everywhere you roam w You become part of the network economy w This steel-bound credential stands up to the hard knocks of everyday wear, including sessions in the swimming pool or clothes washer loading..
