Virtual machines of a virtual data center generate runtime instances with a software image, hardware configuration, management configuration and user/service configuration. Virtual data center resource use is monitored by reference to the management configuration of runtime instances, such as for environmental controls like power, cooling and balancing, or for policy limitations on users, software or hardware. Users or services generate runtime instances of stored virtual machines by reference to the user/service configuration, such as pricing or priority. In one example embodiment, the virtual machine software image comprises an application system preparation file that populates a read only application image common to plural virtual machines. Information unique to each virtual machine with respect to the application is maintained in the user/service configuration of the virtual machine and version information is maintained in the management configuration of the virtual machine. Updates to the application across each virtual machine are performed by updating the read only image or any of its configuration information for hardware configuration, management configuration or user/service configuration.

A speaker recognition system for authenticating a mobile device user includes an enrollment and learning software module, a voice biometric authentication software module, and a secure software application. Upon request by a user of the mobile device, the enrollment and learning software module displays text prompts to the user, receives speech utterances from the user, and produces a voice biometric print. The enrollment and training software module determines when a voice biometric print has met at least a quality threshold before storing it on the mobile device. The secure software application prompts a user requiring authentication to repeat an utterance based at least on an attribute of a selected voice biometric print, receives a corresponding utterance, requests the voice biometric authentication software module to verify the identity of the second user using the utterance, and, if the user is authenticated, imports the voice biometric print.

The battery assembly has a deployed configuration in which the battery assembly has the general form of and functions as a conventional battery format, and a recharge configuration in which the data and power connector plug is made accessible to enable said connector to be connected to a suitable receptacle on a computing or peripheral device for recharging of the battery.

A data chunking system divides data into predominantly fixed-sized chunks such that duplicate data may be identified. The data chunking system may be used to reduce the data storage and save network bandwidth by allowing storage or transmission of primarily unique data chunks. The system may also be used to increase reliability in data storage and network transmission, by allowing an error affecting a data chunk to be repaired with an identified duplicate chunk. The data chunking system chunks data by selecting a chunk of fixed size, then moving a window along the data until a match to existing data is found. As the window moves across the data, unique chunks predominantly of fixed size are formed in the data passed over. Several embodiments provide alternate methods of determining whether a selected chunk matches existing data and methods by which the window is moved through the data. To locate duplicate data, the data chunking system remembers data by computing a mathematical function of a data chunk and inserting the computed value into a hash table.

A method and system tracks objects using a surveillance database storing events acquired by a set of sensors and sequences of images acquired by a set of cameras. Sequences of temporally and spatially adjacent events sensed by the set of sensors are linked to form a set of tracklets and stored in the database. Each tracklet has endpoints being either a track-start, track-join, tracklet-merge or tracklet-end node. A subset of sensors is selected, and a subset of tracklets associated with the subset of sensors is identified. A single starting tracklet is selected. All sequences of tracklets temporally and spatially adjacent to the starting tracklet are aggregated to construct a tracklet graph. The track-join nodes and the track-split nodes are disambiguated and eliminated from the track graph to determine a track of the object in the environment.

A method and package for storing a pressurized container which is filled with a drug formulation at a predetermined pressure. The drug formulation includes a mixture of a drug and a propellant.

A method for inserting a digital signature into digital data is provided. The digital data has bits and the method includes the steps of: assigning predetermined bits of the digital data for receiving the digital signature; signing the digital data excluding the predetermined bits resulting in the digital signature; and inserting the digital signature into the predetermined bits of the digital data for subsequent authentication of the digital data. Also provided is a method for authenticating digital data having the embedded digital signature in the predetermined bits of the digital data including the steps of: extracting the digital signature from the predetermined bits; decrypting the digital signature from the digital data resulting in a first hash; applying a known one-way hashing function used by an encoder of the digital data to the digital data excluding the predetermined bits resulting in a second hash; and comparing the first hash to the second hash wherein if the first hash matches the second hash the digital data is authentic. In a preferred version of the methods of the present invention, the method further includes the step of inserting associated data into the digital data prior to the signing step such that the digital signature authenticates both the associated data as well as the digital data. Preferably, the associated data is inserted into the bits of the digital data excluding the predetermined bits.

A spanning storage interface facilitates the use of cloud storage services by storage clients. The spanning storage interface presents one or more data interfaces to storage clients at a network location, such as file, object, data backup, archival, and storage block based interfaces. The data interfaces allows storage clients to store and retrieve data using non-cloud based protocols. The spanning storage interface may perform data deduplication on data received from storage clients. The spanning storage interface may transfer the deduplicated version of the data to the cloud storage service. The spanning storage interface may include local storage for storing a copy or all or a portion of the data from storage clients. The local storage may be used as a local cache of frequently accessed data, which may be stored data in its deduplicated form.

In certain embodiments of the present invention, the distributed data repository system is message-centric operative to store message payloads transmitted from client nodes. In certain embodiments, the distributed data repository system is BLOB-centric, maintaining binary data objects and indexes of attribute values that map to the binary data objects. Of course, the present invention can be utilized to store a great variety of digital data contained in message payloads.

In this manner, each data repository node in the distributed system can fulfill any client request, while reducing the storage and memory requirements for each data repository node. The reduced storage and computational requirements enable each distributed data repository node to be hosted by an inexpensive hardware platform and, therefore, allow for the deployment of large numbers of distributed data repository nodes to achieve a distributed data repository system featuring high availability and reliability. In certain embodiments, each distributed data repository node is further equipped to act as an instant messaging (or other one-way messaging) server to allow client nodes to establish instant messaging connections with the data repository nodes in the distributed system.
