Personalizing communications services using environmental data
A method for personalizing communication services includes setting a series of selectable options as a default for a system that provides personalized communication services. When a communication from an initiating party is received, a computer of the system automatically determines, based on environmental data provided for the communication independent of information provided by the initiating party during the communication, predictive information that predicts potential objectives potentially sought by the initiating party in initiating the communication. Probabilities are assigned, based on the predictive information, that selectable options will address the potential objectives. The default series of selectable options are dynamically updated based on the assigned probabilities. Communications with the initiating party are in accordance with a script that includes the dynamically updated series of selectable options. |

In an embodiment, techniques for sustaining session connections are provided. The techniques send heartbeat messages when not sending a message may cause the session connection to close because of a timeout condition. Heartbeat messages are valid transport layer messages that will be ignored by protocols at higher levels of a data communications stack. As an example, the techniques may send a TCP message containing only a carriage return and line feed (“CRLF”) in its payload. Because the TCP layer considers a message containing only a CRLF to be a valid TCP message, intermediary computing devices such as proxy servers may not interpret heartbeat messages as “keep alive” messages, and may sustain session connections. |

Extending organizational boundaries throughout a cloud architecture
An information sharing paradigm for a cloud computing solution enables flexible organizational boundaries with respect to cloud resources. Cloud service customers manage their own organization boundary but can extend that boundary selectively by associating cloud resources they own with sets of domain names that may be associated with requests for cloud resources that the organization may be willing to share with other organizations that are using the cloud environment, and by ensuring that any such requests for resources that are shared in this manner are associated with one or more message handling policies that have been defined by (or otherwise associated with) the resource-owning organization. Cloud resources owned by an organization (even those marked as “internal only”) may be selectively shared with one or more other organizations using the cloud environment depending on the domain names associated with the requests. Message handling policies are enforced with respect to shared resources. |

Authenticated remote pin unblock
This invention provides a simple and secure PIN unblock mechanism for use with a security token. A set of one or more passphrases are stored on a remote server during personalization. Likewise, the answers to the passphrases arc hashed and stored inside the security token for future comparison.

In a method, a request is received from a tagger to associate a taggee with electronic content. Before the association is made (and potentially shared), the tag data is encrypted. The cryptographic key is sent to the taggee. The encrypted tag data is stored and indexed based on an address associated with the taggee, such as the taggee's email address. When the taggee receives and activates the cryptographic key, the tag data is decrypted and an association is made between the taggee and the electronic content. Biometric data of the taggee included in the electronic content may then be collected and shared. |

Managing rendezvous point redundancy in a dynamic fabric network architecture
Multi-destination frames in a network fabric may be carried in IP multicast packets. As such, the network fabric may us IP multicast technique such as a PIM protocol for handling the multi-destination frames. To provide redundancy, the system administrator can use phantom rendezvous points (RPs) that include multiple physical RPs where one of the RPs serves as a primary RP and the other RPs serve as secondary RPs (e.g., backup RPs). Instead of the system administrator manually configuring the phantom RPs, the RPs are automatically configured. To do so, the system administrator may use a GUI to provide multicast groups allocated for the multi-destination traffic, the number of desired phantom RPs (or physical RPs), and the desired RP redundancy. Based on these parameters, a data center manager generates one or more templates that automatically configure the network devices in the fabric as they are booted. |

Methods for cryptographic delegation and enforcement of dynamic access to stored data
Efficient methods for assigning, revoking, and realizing access to stored data involve a cryptographic key hierarchy and a set of operations performed on cryptographic keys and performed on the data objects to be protected. In addition to providing confidentiality and integrity for data objects, the methods allow access to selected data objects to be permanently revoked for all entities without requiring all instances of the data objects to be destroyed or overwritten. The methods also support access right modifications for a data object without requiring the re-encryption of the entire data object; instead, certain keys are selectively re-encrypted and re-authenticated to implement access control changes. The key hierarchy is parameterized to enable flexible performance tuning, and to provide efficient random access, keying and other security operations are performed for individual blocks within a data object rather than only for the entire data object. |

Arrangement and method for determining the spatial direction of radiation incidence
The present disclosure relates to an optical receiver. The optical receiver has a first photosensor and a second photosensor disposed within a substrate.

Disclosed are a solar cell and a method for manufacturing the same.
