  • Publication number: 20110010762
    Abstract: In providing identity management in distributed systems, it is known to provide a user with a single sign-on to accounts with different service providers with whom the user interacts by communicating with the service providers' computers. Such a single sign-on is provided by having the user authenticate himself to an identity provider computer, and thereafter relying on that identity provider computer to issue identity assertions on his behalf. An identity provider validation service is proposed with which service providers can interact on receiving an identity assertion on behalf of a user. This allows the service provider to rely only on the identity provider validation service rather than having to rely on the numerous identity providers who might issue identity assertion on behalf of one of their users.

  • Patent number: 7685425
    Abstract: A server computer storing computer files, each computer file having an associated unique digital signature, receiving requests for access to one or more such computer files, only allows access to the or each computer file if their associated digital signatures are valid. Thus, if a computer file has been tampered with by an unauthorized third party, the digital signature associated with that computer file will prove to be invalid when checked and the server computer will not serve the computer file at all. In this way, a computer file that has been tampered with can never leave the server computer, much improving the security of the stored computer files.
