20090097660 | MULTI-FACTOR CONTENT PROTECTION - Protecting content. A recipient receives content from a publisher. Some content is managed by an access server. The access server controls the recipient's use of managed content through interaction with a trusted agent at the recipient. The content is encrypted to a content key, and the content is associated with policy information. The policy information includes the content key for decrypting the content. The policy information is encrypted to an access server key allowing the policy information to be decrypted by the access server. The content key is received from the access server. The content key is encrypted to a trusted agent key. The content key is further encrypted to additional factor(s) defining additional content protection beyond that provided by trusted agent. The content key is decrypted using the trusted agent key and the at least one additional factor. The content is decrypted using the content key. | 04-16-2009 |
20090158384 | DISTRIBUTION OF INFORMATION PROTECTION POLICIES TO CLIENT MACHINES - One embodiment includes a method which may be practiced in a computing environment where resources are distributed. The method includes acts for obtaining policy information defining restrictions on resources distributed in the computing environment. The method includes sending a request to a server for metadata about one or more resource protection policies at the server. In response to the request, metadata about one or more resource protection polices at the server is received from the server. The metadata from the server is analyzed. Based on analyzing the metadata, one or more resource protection policies stored at the client are updated. | 06-18-2009 |
20090192942 | PRE-PERFORMING OPERATIONS FOR ACCESSING PROTECTED CONTENT - The present invention extends to methods, systems, and computer program products for pre-performing operations for accessing protected content. Cryptographic user key pairs can be pre-generated and distributed in response to a variety of different events prior to provisioning client machine for accessing protected content. Usage licenses can be pre-generated and allocated prior to requests for usage licenses. Usage licenses can be pre-obtained for client machines prior to client machines access protected content. Pre-performed operations can be performed in response to detected events, such as, for example, reduced resource consumption in a Digital Rights Management system. | 07-30-2009 |
20090222879 | SUPER POLICY IN INFORMATION PROTECTION SYSTEMS - Providing access to information based on super policy. Information is associated with author policy expressing restrictions on use of the information The author policy is processed using super policy programmatic code to generate a composite policy. The composite policy includes a combination of the author policy and super policy applied by the super policy programmatic code, such that restrictions are added to or removed from the author policy to create the composite policy. A request for the information is evaluated. This includes evaluating information about the requester against the composite policy to determine if the requester is authorized to access the information. A determination is made that the requester is authorized to access the information based on the composite policy, where after the requester is authorized to access the information based on the composite policy, access is granted to the information to the requester. | 09-03-2009 |
20090300706 | CENTRALLY ACCESSIBLE POLICY REPOSITORY - The present invention extends to methods, systems, and computer program products for a centrally accessible policy repository. Protection policies for protecting resources within an organization are stored at a central policy repository. Thus, an administrator can centrally create, maintain, and manage resource protection polices for all of the organizational units within an organization. Accordingly, resources consumed when performing these protection policy related operations is significantly reduced. Additionally, since protection policies are centrally located, there is increased likelihood of being able to consistently apply an organization's protection policies within different organizational units, even when protection policies change. | 12-03-2009 |
20090328156 | WORKFLOW BASED AUTHORIZATION FOR CONTENT ACCESS - The present invention extends to methods, systems, and computer program products for workflow based authorization for content access. A workflow can be triggered when a protection policy does not fully express an intended recipient's rights in protected content. A workflow processes relevant inputs to more fully express the intended recipient's rights in protected content. Workflows can provide policy item updates and authorizations decisions with respect to protected content. Through the use of workflows to make an authorization decision, access to information can become more flexible, allowing it to follow the desired flow of information throughout its lifecycle. This flexibility allows organizations to protect their information without worrying about the protection stopping the natural flow of business. | 12-31-2009 |
20120084565 | CRYPTOGRAPHIC DEVICE THAT BINDS AN ADDITIONAL AUTHENTICATION FACTOR TO MULTIPLE IDENTITIES - Binding a security artifact to a service provider. A method includes generating a pseudonym for a security artifact. The pseudonym is an identifier of the security artifact to the service provider that is unique to the service provider in that the pseudonym is not used to identify the security artifact to other service providers. Further, the pseudonym uniquely identifies the particular security artifact to the service provider even when a user has available a number of different security artifacts to authenticate to the same service provider to access a user account for the user. The method further includes providing the pseudonym for the security artifact to the service provider. The pseudonym for the security artifact is bound with a user account at the service provider for a user associated with the security artifact. | 04-05-2012 |
