Abstract: The present invention is directed to a method of calculating the results of a moving k-nearest query and safe exit locations in a road network, and more particularly to a method and apparatus that receive a request from a client terminal and provide the results of a k-nearest query, a safe zone and safe exit locations together. In the present invention, a query is processed in a server, a request for a query from a querying user and the location information of the querying user are received from an LBS, the location information of the querying user is anonymized and then the query request is transferred to the server, and query results corresponding to the anonymized location information of the querying user are received from the server and then transferred to the querying user, thereby protecting the location information of the querying user.

Abstract: The present invention relates to a method for a page-level address mapping based on flash memory and a system thereof. A method for a page-level address mapping based on a flash memory according to an embodiment of the present invention includes the steps of: receiving a write operation from a file system; generating condensed mapping information using a size of data information of the write operation and a start logical address of sequentially allocated logical addresses of the write operation; and storing the condensed mapping information as a first mapping table in a memory of a flash translation.
