Abstract
Exposure of sensitive information to users is controlled using a first security token containing user identity and user credentials to represent the user who requests services, and a second security token containing two other identities, one identifying the token issuer and the other identifying the owning process. When requesting services, the token-owning process sends a security token to indicate who is making the request, and uses its key to digitally sign the request. The token-owning process signs the request to indicate that it endorses the request. A receiving server accepts a request if (1) the token-owning process endorses the request by signing the request; (2) the token is valid (token is signed by its issuer and the digital signature is verified and unexpired); (3) user entity, which can be a real user or a deployment or a server process, that is represented by the token has the authorization to access the specified resources; and (4) the token-owning process is authorized to endorse the user entity represented by the token to access the specified resources.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
