THE METHOD FOR SHARING DATA AND APPLICATION BASED CLOUD COMPUTING

摘要

PURPOSE: A cloud computing based data sharing method and an application sharing method are provided to enable a user to share applications with other users in anywhere by using a mobile terminal. CONSTITUTION: If shared data is set from data stored in a user space of a cloud interface, the cloud interface transmits meta data which is necessary to access the shared data to a user terminal(S203). If other user terminals are adjacent to the user terminal, a direct sharing method is selected in the user terminal(S204). If other user terminals are not adjacent to the user terminal, an indirect sharing method is selected. The user terminal transmits the meta data to other user terminals by using NFC(Near Field Communication) and requests data sharing to the cloud interface if the user terminal access other user terminals in a direct sharing method(S209).
