Abstract: A method and a system for an access control are provided to handle multiple access entities as an integrated one access entity by using integrated identifier information of the multiple access entities. An integrated identifier database(300) stores integrated identifier information corresponding to an identifier combination of an accessible entity. When multiple access entities request an access in a service, an access control part(200) performs an access control about the multiple-access entities and the integrated identifier information based on a service identifier of the multiple-access entities. The integrated identifier information is extracted from the integrated identifier database in response to an identifier list of the multiple-access entities.

Abstract: A computer readable recording medium recording data structure which performs a data search operation, and a method for searching for, saving and deleting data are provided to provide a data structure, for enabling a memory to be maintained efficiently and a user to search for data rapidly when various computer applications are developed. A method for searching for data by using a data structure includes the following several steps. A pointer moves to a root cloud in order to search for a specific key in cloud fields(S200). A computer checks over whether or the root cloud is a null cloud(S210). If so, the computer finishes searching for the key(S260). If not so, the computer checks whether there exists the specific key within a range from the cloud(S220). If not so in the step S220, the pointer moves to a right side cloud(S250) and the computer repeats the step S210. If so in the step S220, the computer checks whether there exists a node having the same distance attribute as the specific key among the nodes forming the cloud(S230). If there exists the node, the computer finishes searching for the specific key(S270). If there exists no node, the pointer moves to a lower level cloud having a representative node having the distance attribute nearest to the specific key among the lower level clouds(S240).

Abstract: A method and a system for identifying a user with multimodal biometric information are provided to increase a recognition rate by applying at least one single biometric recognition technology through a multimodal biometric recognition technology for accepting all users, and using the multimodal biometric information, and reduce the number of target users by filtering the immigration-prohibited users before immigration control. An immigration-prohibited user searcher(500) checks whether a user is an immigration-prohibited user by searching a database storing ID or biometric information of the immigration-prohibited users based on ID information of the user or biometric information(501) identifying the user. A biometric recognizer(510) compares feature(530) extracted from the respective biometric information of the user with the stored feature when the user is not the immigration-prohibited user. A biometric searcher(520) generates a candidate list according to a matching degree by comparing the feature extracted according to a type of each biometric information with the feature stored in the database storing biometric feature when the biometric recognizer does not identify the user. A display unit displays the candidate list at an immigration gate.

Abstract: A device and a method for performing an e-vote using a mobile terminal are provided to identify a voter with a certificate without making the voter report the e-vote previously when the voter casts a ballot with a mobile terminal of the voter, and guarantee secrecy of the e-vote by encoding voting contents of the voter and deleting a user ID of a mobile terminal user. A voter ID checker(310) authenticates a voter based on a certificate received from a mobile terminal(100) of the voter through the mobile network. An encoding key manager(330) generates and transmits an encoding key for encoding voting contents to the mobile terminal. An election information provider(340) transmits election information including candidate information to the mobile terminal. A voting result storing part(350) decodes the encoded voting contents of which an ID of the voter is removed from the encoded voting contents. A duplicated voting preventer(320) rejects a reconnection trial to an e-vote device(300), and an online/offline duplicated voting trial after the e-vote is completed. An external connector(360) is connected to a CA(Certificate Authority) issuing the certificate including a PIN(Personal ID Number) of the voter to the mobile terminal.
