Abstract: PURPOSE: A method and a system for protecting the privacy of contact information are provided to prevent contact information from being exposed to the outside by restricting access rights for the contact information. CONSTITUTION: An acquisition attempt sensing unit(110) senses an external communication terminal which attempts to acquire contact information included in a profile. An access control unit(120) determines the provision of the contact address by authenticating permission for the external communication terminal according to an acquisition attempt. When the external communication terminal is sensed, the access control unit displays CAPTCHA(Completely Automated Public Turing test to tell Computers and Humans Apart) and receives a return message for the displayed CAPTCHA. When the CAPTCHA is matched with the return message, the access control unit allows a user to access the contact address by authenticating the permission for the external communication terminal. [Reference numerals] (100) Access control unit; (110) Acquisition attempt sensing unit; (120) Access control unit; (130) Relay processing unit; (140) DataBase

Abstract: PURPOSE: A data managing apparatus and a data managing method are provided to protect the privacy of a user from being interrupted. CONSTITUTION: An encryption part(108) encrypts the stored data of clients. An index generating part(110) generates a bucket-based index with respect to data in a bucket section of a pre-set length. A data managing part(104) transmits the encrypted data and the index to a server side data managing unit(200). The data managing part transmits cyclic bucket query information to the server side data managing unit. When the encrypted data corresponding to the query information is received from the server side data managing unit, the data managing part decodes the encrypted data.
