Abstract: The present invention relates to a method and an apparatus for generating an index for an encrypted field in order to protect private information in database. The method for generating the index for the encrypted field according to an embodiment of the present invention constructs an index as encrypted data itself without decrypting and storing contents of the encrypted field, constructs an index using distance information between encrypted data and a pre-configured reference value when the index is constructed, calculates a distance value from the reference value even when a search is performed, and performs a search by comparing the distance value with constructed index information table. In particular, when duplicated data exists, the present invention configures the duplicated data as a set of lower leaf nodes for a leaf node, thereby minimizing a search time.

Abstract: Disclosed is an apparatus for controlling access to a security content using near field network communication of mobile devices. A policy issuance provider registration unit requests a content security policy for a first content, a security content, to a service server, receives the content security policy for the first content, requests to the service server for a first mobile device to be registered as a content security policy issuance provider, and receives a result of registration and a provider policy from the service server. A policy issuance provider converting unit converts the first mobile device to the content security policy issuance provider when receiving a request for access for browsing the first content through near-field network communication from another mobile device in which a DRM client application is being executed.

Abstract: A device and a method for encoding a data column are disclosed. A schema inquiry unit inquires into a schema of an original table which is a data table for performing encoding in a database in which a plurality of data tables are stored. A backup performing unit generates schema information of a backup table on the basis of the schema of the original table, generates a backup table by using the schema information of the backup table so as to copy data of the original table into the backup table, changes the original table by adding a backup column to the original table, and inactivates constraint conditions included in the changed original table so as to copy original columns included in the changed original table into the backup column. An encoding unit encodes data of an encoding target column, a column in which encoding is to be performed in the changed original table, and enters the data in each field of the original columns of the changed original table.

Abstract: Disclosed are a file-processing device for executing a pre-processed file, and a recording medium for executing a related file-processing method in a computer. Once a request for registry information corresponding to the extension of a file is inputted according to a request for the execution of the file selected by the user, a registry-converting unit outputs a preset substitute value instead of the registry default value for executing a connection program corresponding to the extension of the file as the result value for the registry information request. A control unit pre-processes the file through a control program set in correspondence to the substitute value. A file-executing unit executes the file by executing the connection program of the file corresponding to the registry default value after pre-processing.
