The methods to prevent leakage of personal information

     Nowadays, Nate and Nonghyup , famous sites for bank and community, were seriously damaged by hackers ,and most personal information was leaked. However, there is few solutions for Korea to deal with these damages, victims is getting increased. I'd like to write down my own methods to prevent leakage of personal information

     First of all, we need to change password as frequently as possible. I was also hacked ,and the hacker asked my relativeto send money to his account. Since i didn't change my password so long, I think this may happen. Even though site is hacked, if we change our password frequently, we can keep our contents and information in our sites. I think it's the easiest way to prevent our information from hackers and hacking.

     In the second place, usually Korean sites ask us to write our ID number for sign. I think this system cause leakage of our information. Google and other foreign sites don't request people to put id number ,and I know that the reason Korean sites request us to put id number is to prevent overload. However, though many people in the world use google, the site hardly make troubles about overload. Therefore, I think Korean sites also change the system not to put Id number for sign like google.

     The third method is that each site try to make strong system to protect from hacker's attack. Hackers are so talented and trained well. As no.1 nation of internet and IT, we must come up with compete systems to prevent hacking.

     Changing password, altering whole system for sigh and making more strong security system are all not easy.

However, our personal information is so important and valuable. I hope we can come up with complete systems and methods as soon as possible so make people all over the world can use internet freely.
