Abstract: There is a direct relation between the resource of system and users authentication, but the authentication of the most systems is based on passwords . Because of the factors of human, the passwords are not secure. So the paper pu ts forward HVP(half visual passwords) based on traditional passwords and based o n humans limitless ability on recognition of image. This kind of password can fr ee the user from the trouble of remembering meaningless traditional passwords an d improve efficiency of remembering and security. The paper gives the definition and authentication process of HVP. It also examines the HVP and it is shown tha t the HVP is easier to recall and is security.
