    Advantages and Disadvantages of Java Ring

    What is Java Ring?

    A finger ring containing a small microprocessor is called a Java Ring. It is wearable on a finger and a type of personal computer ring. To authenticate you in every situation the user can carry it anytime and anywhere. It is an opening as it is not very popular. A real-time clock, java virtual machine(JVM), RAM(32 KB) and ROM(134 KB) are the main components of it.

    Java Ring

    Java bytecode is executed on the JVM which is the “processor architecture”. It is available for a large variety of hardware platforms and mostly implemented in software. It has a diameter of 16 millimetres and is a stainless-steel ring. An iButton of 1-million-transistor processor is also there.

    Advantages

    • A simple, secure way is provided by it to identify a person or asset. An electronic serial number that is never duplicated is also served by it.
    • Authentication to users is provided by Java Ring. For the administrator it is easy to maintain the security infrastructure.
    • For one or more applications, it can act like a small change purse and can be a personalized token.
    • For protected assets and information it is a personalized key. Opening a lock is enabled by touching the correct key to an iButton reader.

    Disadvantages

    • An individual might need to carry more than one Java Ring as the limited amount of information can be stored.
    • ibutton can be purchased for the cheaper price but a receiver is needed for its function such as blue dot receptor which is very expensive.
    • Limited processor power and memory is there in iButton. It is imperative to move the processing load to the application server for performance and scalability.
    • User mobility is not automatically allowed by a Java Ring-based system.
