Publication number: 20140280494Abstract: A relay component for a back office service creates an externally exposed REST service endpoint in front of the back office service. Instead of calling the back office service directly, REST service clients make REST service calls to the relay component using the HTTP protocol. The relay component coverts the data to XML format and sends it in a SOAP call to the back office service. The relay component receives the response from the back office service as a SOAP response that is converted to a REST message to be sent to the REST client.Type: ApplicationFiled: April 29, 2013Publication date: September 18, 2014Applicant: Microsoft CorporationInventors: Alexander Nikolayevich Samoylenko, Carlos Omar Ortiz Rodriguez, Robert Aron Drollinger, Sandeep Kuruvilla Lukose, Chandramouli Venkatesh, Kyle Stapley Young, Syed Mohammad Ali

Patent number: 7891007Abstract: A method for managing rights in digital content includes generating rights data for a piece of digital content and forming a piece of rights managed digital content by associating the rights data with the piece of digital content. The rights data includes parameters that govern the terms on which the content may be licensed, and may include a list of entities to which the content may be licensed, a respective set of one or more rights that each such entity has in the digital content, and any conditions that may be placed on those rights. A method for licensing rights managed digital content includes receiving a license request for a license to use the piece of rights managed digital content, where the license request includes such a signed rights label. The digital signature on the signed rights label is validated to determine whether a trusted entity issued the signed rights label.Type: GrantFiled: June 28, 2002Date of Patent: February 15, 2011Assignee: Microsoft CorporationInventors: Peter David Waxman, Attila Narin, Scott Cottrille, Vinay Krishnaswamy, Marco A.

Patent number: 7827156Abstract: An organization maintains a computer network comprising at least a forest A and a forest B, where forest A has a directory A and a querying entity A capable of querying directory A, and forest B has a directory B and a querying entity B capable of querying directory B. Querying entity A receives a request from the user and decides whether to grant the request based at least in part on whether the user is a member of the group. Thus, querying entity A queries directory A to return information on the group, is directed to forest B, contacts querying entity B, requests querying entity B to query directory B whether the user is a member of the group, receives a response, and grants the request from the user based at least in part on whether the user is a member of the group.Type: GrantFiled: February 26, 2003Date of Patent: November 2, 2010Assignee: Microsoft CorporationInventors: Peter David Waxman, Chandramouli Venkatesh, Yevgeniy Eugene Rozenfeld, Attila Narin

Patent number: 7577999Abstract: A licensor receives a request from a requestor including an identifier identifying the requestor and rights data associated with digital content, where the rights data lists at least one identifier and rights associated therewith. The licensor thereafter locates the identifier of the requestor in a directory, and locates in the directory based thereon an identifier of each group which the requestor is a member of. Each of the located requestor identifier and each located group identifier is compared to each identifier listed in the rights data to find a match, and a digital license to render the content is issued to the requestor with the rights associated with the matching identifier.Type: GrantFiled: February 11, 2003Date of Patent: August 18, 2009Assignee: Microsoft CorporationInventors: Attila Narin, Chandramouli Venkatesh, Frank D.

Patent number: 7549060Abstract: Content is encrypted according to a content key (CK) ((CK(content))), (CK) is protected according to a license server public key (PU-DRM), and rights data associated with the content is retrieved from a rights template and protected according to (PU-DRM). The protected items and a digital signature from the rights template are submitted as a rights label to the license server for signing. The license server verifies the rights template signature, and if such signature verifies signs the rights label to result in a signed rights label (SRL), and returns same. The SRL is concatenated with (CK(content)) and both are distributed to a user. To render the content, the user submits the SRL to the license server to request a license.Type: GrantFiled: June 28, 2002Date of Patent: June 16, 2009Assignee: Microsoft CorporationInventors: Steven Bourne, Chandramouli Venkatesh, Vinay Krishnaswamy

Patent number: 7502945Abstract: Content is encrypted according to a content key (CK) to result in (CK(content)) and the content key (CK) is protected according to a public key for a license server (PU-RM). Rights data is retrieved from a rights template to be associated with the content, and rules for modifying the retrieved rights data are also retrieved from the retrieved rights template. The retrieved rights data from the rights template is modified according to the rules, and the rights data and the protected content key (CK)) are submitted as a rights label to the license server for signing thereby. The license server thus validates the rights label and, if valid, creates a digital signature based on a private key (PR-RM) corresponding to (PU-RM) and based at least in part on the rights data to result in a signed rights label (SRL), and returns the SRL.Type: GrantFiled: March 5, 2004Date of Patent: March 10, 2009Assignee: Microsoft CorporationInventors: Steven Bourne, Marco A.

Patent number: 7366915Abstract: A digital license corresponds to encrypted digital content and includes a content key for decrypting same. The content key is encrypted and is decryptable by a decryption key available only to the first persona, the license thereby being tied to the first persona. The license is a first license and further includes referral information specifying a first location at which a second persona may obtain a second license for the content tied thereto. The second persona requests to render the content by way of the first license and the request is denied because the first license is not tied to the second persona. The referral information is obtained from the first license and employed to initiate contact with the specified first location and obtain the second license tied to the second persona.Type: GrantFiled: April 30, 2002Date of Patent: April 29, 2008Assignee: Microsoft CorporationInventors: Attila Narin, Peter David Waxman, Christopher Robert Richard Madonna, Marco A.

Patent number: 6990502Abstract: A computer network has storage devices organized into X levels and storing element-group information. To determine whether an element is a member of any target groups, each target group is validated by searching the storage devices to find a target group item and, if found, placing the target group in a validated target bin (V). Also, the element is validated by searching the storage devices to find an element item, and if found, determining from the item all groups that the element is listed as being a member of and placing such member-of groups in a search bin (S). If (S) intersects (V), the element is a member of a target group. If not, all groups in (S) are moved to a queue (Q1) corresponding to the storage device at level 1 and an iterative process searches for a membership path from the element to any target group.Type: GrantFiled: February 26, 2003Date of Patent: January 24, 2006Assignee: Microsoft CorporationInventors: Peter David Waxman, Chandramouli Venkatesh, Yevgeniy (Eugene) Rozenfeld, Attila Narin, David Larson
