Insurance data needs to be circulated between servers of different departments, even different companies or entities. Currently, Secure File Transfer Protocol (SFTP) mode is generally adopted for the transmission of insurance data between servers of a plurality of entities. That is, server a sends insurance data to server B, typically by first transferring the data to an SFTP server.
