Abstract
In a security card check type computer security method, it is determined whether a predetermined check condition for checking a right of a security card to use a computer, which stores at least security information enabling the identification of the right of use of computer, is satisfied and a combination key requiring checking is generated. When the combination key is received, check result data with respect to the security card is waited for. The security information of the security card is checked to obtain the check result data. The right of use of computer is controlled depending on the check result data.
Claims23
A security card check type computer security method comprising the steps of:
- determining whenever a special key or a combination key is generated;
- waiting for IC card check whenever said special key or said combination key is generated;
- checking IC card and returning the checked result data;
- determining whenever said check result data is proper;
- and
- permitting use of the computer whenever said check result is proper.
A security card check type computer security method comprising the steps of:
- (a) determining whether a predetermined check condition for checking a right of a security card to use a computer, which stores at least security information enabling the identification of the right of use of computer, is satisfied and a combination key requiring checking is generated;
- (b) waiting for check result data with respect to said security card when said combination key is received;
- (c) checking the security information of said security card and obtaining the check result data;
- and
- (d) controlling the right of use of computer depending on the check result data.
A security card check type computer security method comprising the steps of:
- (a) determining whether a predetermined check condition for checking a right of a security card, which stores at least security information enabling the identification of the right of use of computer, to use a computer is satisfied;
- (b) generating a check command to check said security card when the predetermined check condition is satisfied;
- (c) checking the security information of said security card according to the check command and obtaining check result data;
- and
- (d) controlling the right of use of computer depending on the check result data.
A method for providing security to a computer to only authorized users, comprising the steps of:
- reading a password from an IC security card attached to said computer upon encountering certain conditions;
- determining if a password read from said security card matches an approved password stored within said computer;
- permitting use of said computer if said read password is authorized;
- and
- locking said computer if said password is not authorized or when no security IC card is attached to said computer, said certain conditions being receipt of a hot key keystroke by said computer irrespective of whether said computer is locked or not.
A method for providing security to a computer to only authorized users, comprising the steps of:
- reading a password from an IC security card attached to said computer upon encountering certain conditions;
- determining if a password read from said security card matches an approved password stored within said computer;
- permitting use of said computer if said read password is authorized;
- and
- locking said computer if said password is not authorized or when no security IC card is attached to said computer, said certain conditions being booting up of said computer, having a first predetermined period of time pass without a user actuating an input device on said computer and detaching said IC card from said computer.
A method for providing limited security access to a computer already booted up, said method comprising the steps of:
- generating a hot key stroke;
- transmitting said hot key stroke to a computer;
- consulting a security IC card attached to said computer to determine whether a password stored on said IC card is approved by said computer;
- and
- permitting use of said computer or locking said computer based on whether a password read from said IC card is approved or not by said computer, said generating step can be accomplished automatically in response to certain computer condition or manually by a user.
