In this paper, we propose identity data backup system for the digital Identity wallet (DIDW) that is a personal identity management system for the Internet. The DIDW is client side software that stores identity data such as personal profile and account (identifier and shared-secret) for logging on to the web sites that has been registered to. The DIDW provides ways of managing distributed identity data conveniently and securely. However, there is concern about loss/damage of the storage and misuse of lost data by malicious people who acquired it. The proposed system provides backup and recovery of the identity data. Suspending of the accounts is also provided for the case that it is assumed that the lost information is acquired by malicious people. The method for securely resuming suspended account and updating shared secret that is used in authentication is also provided.
