Abstract: This disclosure relates to systems and methods for enabling the use of secret digital or electronic information without exposing the sensitive information to unsecured applications. In certain embodiments, the methods may include invoking, by a client application executing in an open processing domain, a secure abstraction layer configured to interface with secret data protected by a secure processing domain. Secure operations may be securely performed on the secret data by the secure abstraction layer in the secure processing domain based on an invocation from a client application running in the open processing domain.

Abstract: This disclosure relates to systems and methods for managing connected devices and associated network connections. In certain embodiments, trust, privacy, safety, and/or security of information communicated between connected devices may be established in part through use of security associations and/or shared group tokens. In some embodiments, these security associations may be used to form an explicit private network associated with the user. A user may add and/or manage devices included in the explicit private network through management of various security associations associated with the network's constituent devices.

Abstract: Systems and methods are described for securely and efficiently processing electronic content. In one embodiment, a first application running on a first computing system establishes a secure channel with a second computing system, the secure channel being secured by one or more cryptographic session keys. The first application obtains a license from the second computing system via the secure channel, the license being encrypted using at least one of the one or more cryptographic session keys, the license comprising a content decryption key, the content decryption key being further encrypted using at least one of the one or more cryptographic session keys or one or more keys derived therefrom.

Abstract: Systems and methods are described for applying digital rights management techniques to tethered devices. In one embodiment, a host device is operable to translate a relatively sophisticated license into a simpler format for use on a relatively low-capability device. In another embodiment, a method of using extended SCSI commands to communicate over a USB connection is provided.

Abstract: Systems and methods are provided for determining a presence of a watermark in electronic data. In certain embodiments, a plurality of keys is generated, and a plurality of payloads are retrieved from electronic data using the keys. A statistical indicia of randomness is generated based on the payloads, and the presence of a watermark is determined when the indicia is below a threshold.

Abstract: Systems and methods are described for applying digital rights management techniques to manage zones in electronic content. In one embodiment, zones are defined in a piece of electronic content, and a license is associated with the electronic content that indicates how the zones are to be accessed or otherwise used. A digital rights management engine governs access to or other use of the zoned content in accordance with the license.

Abstract: Systems and methods are described for performing digital rights management. In one embodiment, a digital rights management engine is provided that evaluates license associated with protected content to determine if a requested access or other use of the content is authorized. In some embodiments, the licenses contain control programs that are executable by the digital rights management engine.

Abstract: This disclosure relates to systems and methods for managing data associated with a user using a personalized cloud storage platform operating as a centralized repository for user data generated from a variety of sources and/or user devices. By centralizing the storage and/or management of personal data that would conventionally be confined between multiple information silos, embodiments of the systems and methods disclosed herein may improve the ability of a user to control their personal data, facilitate utilization of their personal data in a variety of ways not offered by services associated with the silos, and/or allow a user to centrally manage their personal data. Further embodiments disclosed herein allow a user to define one or more policies or other rules associated with personal data stored in their personal cloud.

Abstract: Systems and methods are provided for protecting and managing electronic data signals. In one embodiment a strong watermark is inserted in a data signal that is divided into a sequence of blocks, and a digital signature for each block is embedded in the signal via a watermark. The signal is then stored and distributed. When attempts are made to use or access the signal, the signal is checked for the presence of a watermark containing the digital signature for the desired portion of the signal. If the watermark is found, the digital signature is extracted and used to verify the authenticity of the desired portion of the signal. If not found, the signal is checked for the presence of the strong watermark, which if found causes the system to inhibit further use of the signal, and if not found further use of the signal is allowed.

Abstract: Systems and methods are described for performing policy-managed, peer-to-peer service orchestration in a manner that supports the formation of self-organizing service networks that enable rich media experiences. In one embodiment, services are distributed across peer-to-peer communicating nodes, and each node provides message routing and orchestration using a message pump and workflow collator. Distributed policy management of service interfaces helps to provide trust and security, supporting commercial exchange of value. Peer-to-peer messaging and workflow collation allow services to be dynamically created from a heterogeneous set of primitive services. The shared resources are services of many different types, using different service interface bindings beyond those typically supported in a web service deployments built on UDDI, SOAP, and WSDL.

Abstract: Personal video recorders (PVRs) contain many desirable features, including the ability to skip undesirable portions of a recorded broadcast program. Disclosed is a method and system for a PVR user to share with other users tags identifying desirable program portions or segments (“Hot-Spots”) and undesirable segments (“Cold-Spots”). Other users are able to either automatically or manually to adjust the replay of the program based on the tags.
