Abstract: A method and a device for preventing illegal access in an electronic device are provided to obtain an effect to prevent accessing of an illegal user except an authorized user by operating a system protection program for preventing the illegal access when a prohibited key set by the authorized user is inputted. A password checker(106) determines whether a preset prohibited key is found in a password inputted by a user when an event for system access is generated. A controller(100) prohibits the system access of the user and operates a system protection program when the password checker finds the prohibited key. The password checker determines whether the inputted password corresponds to the preset password and determines whether the prohibited key is found in the inputted password if the inputted password does not correspond to the preset password. The password checker generates the password dynamically changed according to time, performs an additional operation for removing the prohibited key when the prohibited key is found in the calculated password, and determines whether the prohibited key is found in the inputted password when the inputted password is different from the additionally operated password.

Abstract: An apparatus and a method for changing system information in a portable terminal are provided to check whether security information gains admission to entering a management mode for requesting a change of the system information to the operator of the portable terminal and change the system information when it is determined that the security information is admitted, thereby preventing an illegal change of the system information. A memory unit(204) stores security information including specific information for discriminating an operator and information for notifying the admission of system information change. A security management unit(202) determines whether the security information prestored under the control of a control unit(200) gains admission to entering a management mode for changing system information and determines whether the security information gains admission to the change of the system information. The control unit acquires the security information stored in the memory unit when a system information change request is detected, and controls the security management unit to determine whether the security information gains admission to the change of the system information.

Abstract: An apparatus and a method for setting up multiple codes are provided to segment system access rights by allocating multiple codes to one system ID according to lower level lists such that the system can be efficiently operated. A method for setting up multiple codes comprises the following several steps. A controller checks whether a system is in a user registration mode(201). If so, the controller checks whether an integrated code is registered(203). If so, the controller checks whether the system uses a multiple codification scheme(205). If not so in the step 205, the controller makes the system switched to a mode in which the system uses only the integrated codification scheme(207). If so in the step 205, the controller displays corresponding lower level lists, needed in dependent codes, on a display unit(209). The controller checks whether operators are set to the corresponding lower level lists(211).

Abstract: A device and a method for dynamically changing a password are provided to prevent exposure of the password and protect personal information/asset without any additional device by dynamically changing the password based on the random number and an operator, which are selected by user. A storing part(102) stores a preset original password and an arithmetic operator, and a random number generator(106) generates the random number. A dynamic password generator(110) changes the original password dynamically by operating the original password and the random number based on the arithmetic operator. A display part(108) displays the generated random number and an input part(104) receives the password from the user. A password authenticator(112) determines to authenticate the received password by comparing the received password with the password changed in the dynamic password generator.

Abstract: An apparatus and a method for dynamically changing a password are provided to register a final password by using the original password key, randomly selected personal registration information and a predetermined operator to reinforce security. An apparatus for dynamically changing a password includes an input unit(103), a memory(104), a password authentication unit(102), and a controller(100). The input unit registers the original password key with respect to a system, personal registration information, and a corresponding operator and receives a final password key. The memory stores the original password key, the personal registration information, and the corresponding operator inputted through the input unit. The password authentication unit compares the original password key, a second password key generated according to the personal registration information, and the final password key by using the operator and provides password authentication information to the controller according to the comparison result. The controller controls access to the system according to the password authentication information and provides a final password key input request to a user.
