Electricity has become a vital asset in our lives. In our day to day life we depend on electricity for almost everything we do. The generation of electricity is carried out from non-renewable sources which may vanish one day or other in the coming future. Also, renewable installations like solar and wind power options have their own cons which impede their adoption in considerable numbers. With this growth in usage and ever hiking barrier between the supply and demand, the cost per unit of electricity is skyrocketing. This tremendous growth in the cost is shoving the lives of poor in to darkness. A lot of research is going on in the field of renewable energy utilization to make the electricity affordable to all but the efforts that they put in, failed to pull out satisfactory results.

In this internet regime, we depend greatly on internet based services to accomplish our tasks by expending little or no time and even with the least effort possible.

In order to protect the confidential and personal information every internet related service, let it be a banking website or a social networking site prompts you to create a membership and login with the registered username and password every time you visit their websites. This is the only procedure we are following to protect our online data for decades. Even though many complex encryption techniques were evolved in recent past, these techniques ultimately failed to restrict the hackers from intruding into the websites of some leading services with a massive user base. Usually we come across several incidents exposing the loopholes in the leading servers through which the black hat hackers grab the access of other's bank accounts and loot their money in a flash.
