Abstract
Method and apparatus for information transmission are provided. A method for information transmission uses a virtual input layout to encrypt security information. The method uses a server to receive an access request from a user client and to generate a virtual input layout based on information of an actual input layout of the user client. Each key in the virtual input layout has a corresponding relationship with a respective key in the actual input layout, and at least some of the keys in the virtual input layout represent symbols or functions that are different from their corresponding keys in the actual input layout. The server sends the virtual input layout to the user client to be displayed, and subsequently receives from the user client a virtual security information entered by the user according to the virtual input layout displayed. The server then converts the virtual security information to obtain true security information.
