The patent application (Publication Number: US20240013291A1) describes a user terminal with a graphical user interface (GUI) designed for secure data communication with a server in a communication network. The user terminal includes a communication unit, memory storing instructions, and a processor executing these instructions to enable the server to generate multiple graphical messenger profiles representing participants in a group account. These profiles are displayed on the user terminal's screen, with overlapping locations to provide a visual representation of the group's members.

Furthermore, the user terminal allows for the conversion of a private account into a group account, facilitating joint access by multiple users. The processor controls the communication unit to send account conversion requests to the server, leading to the creation of group account information sets stored in both a transaction ledger and a virtual ledger. Real-time monitoring of changes in the group account information ensures that updated data is promptly reflected on the user terminal's screen. Additionally, the GUI includes screens for account management, transaction history display, and user input for desired changes, enhancing user interaction and control over the group account settings. The method also includes features such as masking sensitive information and providing real-time updates to users across different terminals, ensuring secure and efficient data communication within the network.
