According to one aspect of the present invention, a group account service providing server capable of converting a private account into a group account in real time through a terminal of the host of a comprises: an account management unit configured to convert a first account into a group account when a group account conversion request for the first account of a host of a group is generated; a transaction ledger management unit configured to record change information in a transaction ledger for the group account when the change information including at least one of a transaction occurrence event and an information occurrence event is generated for the group account; a virtual ledger management unit configured to generate a virtual ledger to be mapped to the transaction ledger when the first account is changed to the group account.

Group account service providing server and method

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.

Method and system for providing secure data communication between two or more user terminals in a communication network

A user terminal including a graphical user interface (GUI) for providing secure data communication with a server in a communication network is proposed. The user terminal may include a GUI configured to receive one or more user inputs and display data received from the server. The GUI may include a first screen configured to display a first instruction set for converting a private account to a group account and a second screen configured to display a group account information set received from the server. The user terminal may cause the server to generate the group account, control a first database of the server to store a second information set relating to the group account, generate a second virtual database of the server different from the first database, and copy the second information set stored in the first database and record the copied second information set in the second virtual database.
