The present invention extends to trusted third party authentication for Web services. Web services trust and delegate user authentication responsibility to a trusted third party that acts as an identity provider for the trusting Web services. The trusted third party authenticates users through common authentication mechanisms, such as, for example, username / password and X.509 certificates and uses initial user authentication to bootstrap subsequent secure sessions with Web services. Web services construct user identity context using a service session token issued by the trusted third party and reconstruct security states without having to use a service-side distributed cache.

The present invention is directed to suppress data loss caused by power shut-down during a rewriting process and to shorten time required to make a depletion check. A nonvolatile memory apparatus includes a rewritable nonvolatile memory and a card controller. The nonvolatile memory has a physical address area corresponding to a logical address and a save area. In response to a data rewrite instruction on a required logical address, the card controller stores data in a predetermined physical address area corresponding to the logical address to the save area and rewrites the data stored in the physical address area. When rewriting of the physical address area is incomplete, the card controller rewrites the data in the physical address area with the data stored in the save area. Thus, data loss caused by the power shut-down can be suppressed by data backup, and it is sufficient to make the depletion check in two places of the save area and the physical address area.
