摘要:
A method is disclosed for a recipient to receive rights management (RM) protected content. The protected content is encrypted and decryptable according to a content key (KD), where (KD) is found in a corresponding license. In the method, the protected content is received while connectively coupled to a network through which the protected content may be obtained, and it is recognized that the received protected content is in fact protected content. In response to receiving the protected content and recognizing same, the license for the protected content is obtained from an RM server while still connectively coupled to the network and in an automatic manner. Thus, the license is available to the recipient even when such recipient is not connectively coupled to the RM server by way of the network at a later time. In one particular embodiment of the present invention, the protected content is received within an email.
摘要:
A rights-managed email is provided for sending protected content from a sender to a recipient, whereby the recipient can render the protected content with a corresponding license if the recipient satisfies terms set forth in the license. In the email, a main information portion has a message that the email is rights management protected, and an attachment portion has the protected content. The recipient if enabled can render the protected content in the attachment portion. If not enabled, the recipient can only review the main information portion having the message. The enabled recipient recognizes that the email has the protected content in the attachment portion thereof, discounts the main information portion of the email, and examines the attachment portion of the email and proceeds based thereon to render the protected content in the attachment portion.

摘要:
A method is employed to propagate rights management (RM) protection to an email and to an attachment thereof comprising an RM-protectable document. The email with the RM-protectable attachment is authored, and a content key (KD) and a bind ID are generated. RM protection is first applied to the RM-protectable attachment of the email based on the generated (KD) and the generated bind ID, and the RM-protected attachment is attached to the email. RM protection is then applied to the email with the attached RM-protected attachment based on the generated (KD) and the generated bind ID. The RM-protected email and the RM-protected attachment thereof thus share the generated (KD) and the generated bind ID such that a license obtained for the RM-protected email and having therein the generated bind ID and the generated (KD) can be applied to render the RM-protected email and also the RM-protected attachment thereof.

摘要:
A document store delivers a document requested therefrom from a folder having rights information associated therewith. In response to a request for a copy of the document, rights data for the copy of the document is defined based on the rights information of the folder, and the copy of the document and the defined rights data thereof are published to result in a package with the rights data and the copy of the document encrypted according to a content key (KD) to result in (KD(copy)). The formed package is then delivered to the requester. The rights data can be discovered upon the requester attempting to render the package and such discovery triggers a request for a corresponding license based on such rights data. The license includes (KD) therein in a form available to the requester to decrypt (KD(copy)) if the requester satisfies the rights data.

摘要:
A method is disclosed for rendering content encrypted according to a cryptographic key, where the content has corresponding rights data including a decryption key (KD) for decrypting the encrypted content, and where (KD) in the rights data is encrypted according to a public key of a rights management (RM) server (PU-RM) to result in (PU-RM(KD)). The RM server normally delivers (KD) within a license, but upon being decommissioned can no longer issue such license. In the method, a notification is received that the RM server has been decommissioned, and thereafter an attempt is made to render a piece of content. Such content is determined to be protected to the decommissioned RM server, and a request is sent to the decommissioned RM server for the content key (KD) for the content rather than any license. Thereafter (KD) is received from the decommissioned RM server.
