Many people put their personal information online (address, telephone number, and so on) for purpose

I don\'t understand why most websites want users to put their personal information regardless of the type of business. I can provide it to a bank because it deals with money for customers so they need to identify customer\'s information every step. However, I don\'t think portal sites have to confirm user\'s ID when they want to join it because it\'s just search engine, there aren\'t potential harm to users and providers too. The government have implemented the different type of identification system due to the complexity of joining websites and inconvenience of installing various firewall programs. People have experienced to install those programs. Most of them spent a lot of time to install it and have been encountered difficulties because of many reasons like program problem itself, hardware and users\' skills. I know that privacy have to be first things whose company consider but they also are needed to care the user\'s convenience too. I think that it would be good to use smart phone.
