A method and system for providing secure data communication between two or more user terminals in a communication network is proposed. The method may include receiving, from a first user terminal, a first instruction set configured to request that a private account be converted into a group account, the private account owned by a user of the first user terminal. The method may also include generating the group account jointly owned by at least the user of the first user terminal and a user of a second user terminal. The method may also include controlling a first database to store a second information set relating to the group account, and generating a second virtual database different from the first database. The method may also include copying the second information set stored in the first database and recording the copied second information set in the second virtual database.
