Java Ring Technology

1.0INTRODUCTION

1.1       A Portable Wearable Computer

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. In the domain of identification traditional technologies are used, such as the bar codes applied on surfaces, the magnetic stripes, the chip cards, and the RFID labels. To these technologies can be added another successful one, which is based on the 1-wire communication network.

The 1-wire technology has emerged from the evolution of the semiconductor technology. It was designated to some specific applications to substitute the identification by paper label based on bar codes for the electronic circuits. Dallas

Semiconductor was the first producer which developed a large used automated identification through attached chips to objects or persons.

The iButton technology belongs to the category of the technologies of identification by touching. The simplest identification method can be realized by using a

Microsystem with two external electrical wire connexions: signal and ground.

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 spent your entire life practicing 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:

·           It is a safe place to keep the private keys to conduct transactions.

·           It overcomes the deficiencies of the secret password.

·           You eliminate keystroke with a quick, intentional press of the Blue Dot.

·           You keep your computer at hand versus lugging your everywhere you roam.

·           You become part of the network economy.

·           The reading without expensive optical devices.

·           Reading and Writing are done by means of small-sized portable having reduced energy consumption.
