1. An information security system comprising:

  • one or more computer readable memories;

    a first security token, disposed in the one or more computer readable memories, which contains a user identity and one or more user credentials associated with a first user;

    a second security token, disposed in the one or more computer readable memories, which contains an identity of a token issuer and an identity of a first owning process;

    a third security token disposed in the one or more computer readable memories, which contains an identity of a token issuer and an identity of a second owning process; and

    a first trusted server which accesses, via a computer network, a downstream computing service on behalf of the first user by substituting or combining the first security token and the second security token, while preventing the second security token from being exposed to the first user;

    a second trusted server which accesses, via a computer network, the downstream computing service on behalf of the first trusted server by substituting or combining the second security token and the third security token, while preventing the third security token from being exposed to the first trusted server;

    thereby establishing a first security sensitivity level for the first user and a second security sensitivity level for the first trusted server, wherein the first security sensitivity level is a lower access level than the second security sensitivity level for the downstream service and thereby establishing a third security sensitivity level for the second trusted server, wherein the second security sensitivity level is a lower access level than the third security sensitivity level for the downstream service.
