Abstract
An electronic apparatus includes a secure unit to store public key information, an input unit to receive user authentication information and a data searching word, a user authenticating unit to perform user authentication with the inputted user authentication information, an encryption generating unit to generate a searching word encryption to use in data search, and a control unit to control generating the searching word encryption using the previously-stored public key information, the inputted user authentication information, and the data searching word.
Claims23
An electronic apparatus, comprising:
- a secure unit to store public key information;
- an input unit to receive user authentication information and a data searching word;
- a user authenticating unit to perform user authentication with the inputted user authentication information;
- an encryption generating unit to generate a searching word encryption for use in data search;
- and
- a control unit to control generating the searching word using the previously-stored public key information, the inputted user authentication information, and the data searching word.
An encryption method of an electronic apparatus, the method comprising:
- inputting user authentication information and a data searching word;
- performing user authentication with the inputted user authentication information;
- and
- generating a searching word encryption using the inputted user authentication information, the data searching word, and previously-stored public key information.
A non-transitory computer readable medium storing therein a program to implement an encryption method of an electronic apparatus, wherein the encryption method comprises:
- inputting user authentication information and a data searching word;
- performing user authentication with the inputted user authentication information;
- and
- generating a searching word encryption using the inputted user authentication information, the data searching word, and previously-stored public key information.
An encryption method of an electronic apparatus, the method comprising:
- encrypting and storing user information in an encrypted medium;
- authenticating a user, and generating a user password;
- generating, using a searching word provided by the authenticated user and the user password, a searching word encryption of a message together with a storage position of data encryption corresponding to the searching word encryption.
- generating, in response to user input of the searching word after user authentication, a searching query with respect to the password and the searching word;
- performing a test function utilizing a searching query result and the searching word encryption to obtain storage position information of the encrypted message;
- and
- decrypting the encrypted message.
An encryption method of an electronic apparatus, the method comprising:
- encrypting and storing user information in an encrypted medium;
- authenticating a user, and generating a user password;
- and
- generating, using a searching word provided by the authenticated user and the user password, a searching word encryption of a message together with a storage position of data encryption corresponding to the searching word encryption.
A decryption method of an electronic apparatus, the method comprising:
- authenticating a user, and generating a user password;
- generating, in response to user input of a searching word, a searching query with respect to the password and the searching word;
- performing a test function utilizing a searching query result and the searching word encryption to obtain storage position information of the encrypted message;
- and
- decrypting the encrypted message.
