Abstract: The present invention extends to methods, systems, and computer program products for deriving express rights in protected content. Embodiments of the invention provide mechanisms to convert implicit rights to express rights for entities, including applications, inside and outside of an organizational (e.g., enterprise) boundary. The conversion can occur dynamically, based on the information protection policies defined by a policy administrator, granting entities express access to perform tasks on protected content.

Abstract: The present invention extends to methods, systems, and computer program products for separating authorization identity from policy enforcement identity. Embodiments of the invention extend the consumption phase for protected information. Two identities, an authorization identity and a policy enforcement identity, are used for acquiring, issuing and enforcing usage license instead of one identity certificate. The authorization identity is used to evaluate against usage policy. The authorization identity is similar to identification information in an identity certificate. The policy enforcement identity is used to ensure the confidentiality of granted permissions and content key. The policy enforcement identity enforces a usage license on an authorization principal's (e.g., recipient's) machine. The policy enforcement identity's enforcement of a usage license is similar use of a cryptographic key in an identity certificate.

Abstract: The secure application of content protection policies to content. The secure application of content protection polices is accomplished by having an enforcement mechanism monitor policy application points to detect the transfer of content. The enforcement mechanism accesses the content and a determination is made to protect the content. A usage policy is then identified by the enforcement mechanism to apply to the content and the usage policy is then applied to the content, resulting in a usage policy for the content.

Abstract: The offline consumption and publication of protected information in a networked environment. The offline consumption of protected information is accomplished by having the consuming user maintain a store of asymmetric encryption keys. The protected information is encrypted by the publishing user using a symmetric key and the symmetric key is then encrypted using a public asymmetric key associated with the consuming user. The consuming user received the protected information and a usage policy containing the encrypted symmetric key. The consuming user verifies that it can decrypt the symmetric key using a private asymmetric key maintained by the consumer. The user then decrypts the symmetric key and accesses the content of the protected information.
