A registered data in the shared books is simultaneously saved to “Wallet” server temporarily. When sharing partners open his/her “Wallet”, the saved data is delivered from the server. If the saved data is distributed to all sharing partners, it will be deleted from the server completely.
“Wallet” server only relays data. Since all records in an account book are not saved to “Wallet” server, security risks, such as data disclosure, can be reduced. Moreover, in this “Wallet” sharing protocol, each data transmission is manageable even it does not require your personal information. Transmission and reception of records are encrypted by SSL.
