  • Patent number: 12265635
    Abstract: A method enhances authentication requirements to documents of a document repository based, at least in part, on a security policy associated with a branch under which the documents are organized. The method implements an approval service that is identified in a branch policy. The approval service determines whether a user is authorized to modify documents included in the branch. The method further selectively requires multiple authentications from multiple authentication systems in order to access one or more particular branches in a document repository. Further, the multiple authentication systems are based on separate and independent sets of authentication credentials.
