I'm a newbie as far user web authentication and web/internet security areas but my question could either easy or difficult.
So here is it..
I'm developing a registration formthat I'm planning to put on the web . My question is..
How would I be sure that who is login to the site is the right person who claim he is. What authentication structure need to place. In short,for example, if you are login in to your bank under the name 'John Doe',how does the bank know you are John Doe for sure and the name you claim you are.What methods are use to achieve this.
