摘要： Described embodiments provide systems and methods for data encryption. A server communicating data with a client can determine a level of data encryption on the data that the server is capable of handling according to resources available to the server. A level of data encryption can include a type of encryption and a strength of the type of data encryption. The server can receive a level of data encryption on the data that the client is capable of handling according to resources available to the client. The server can identify a level of data encryption with which the server and the client agree to proceed, according to the determined level of data encryption and the received level of data encryption. The server, following a predefined interval, can identify an updated level of data encryption with which the server and the client agree to proceed.

摘要： A system and method for providing load balanced secure media content and data delivery in a distributed computing environment is disclosed. Media content is segmented and encrypted into a set of individual encrypted segments on a centralized control center. Each individual encrypted segment has the same fixed size. The complete set of individual encrypted segments is staged to a plurality of intermediate control nodes. Individual encrypted segments are mirrored from the staged complete set to a plurality of intermediate servers. Requests are received from clients for the media content at the centralized control center. Each individual encrypted segment in the set is received from one of an intermediate control node and an intermediate server optimally sited from the requesting client. The individual encrypted segments are reassembled into the media content for media playback.

摘要： Methods, systems, and apparatus, including computer programs encoded on a computer storage medium, for performing speaker verification. In one aspect, a method includes accessing a neural network having an input layer that provides inputs to a first hidden layer whose nodes are respectively connected to only a proper subset of the inputs from the input layer. Speech data that corresponds to a particular utterance may be provided as input to the input layer of the neural network. A representation of activations that occur in response to the speech data at a particular layer of the neural network that was configured as a hidden layer during training of the neural network may be generated. A determination of whether the particular utterance was likely spoken by a particular speaker may be made based at least on the generated representation. An indication of whether the particular utterance was likely spoken by the particular speaker may be provided.

摘要： A system and method for providing load balanced secure media content and data delivery (10) in a distributed computing environment is disclosed. Media content is segmented and encrypted into a set of individual encrypted segments on a centralized control center (15). Each individual encrypted segment has the same fixed size. The complete set of individual encrypted segments is staged to a plurality of intermediate control nodes (17, 19). Individual encrypted segments are mirrored from the staged complete set to a plurality of intermediate servers (21a-b, 23a-b). Requests are received from clients (11) for the media content at the centralized control center. Each individual encrypted segment in the set is received from one of an intermediate control node and an intermediate server optimally sited from the requesting client. The individual encrypted segments are reassembled into the media content for media playback.

摘要： Provided is a transmission apparatus capable of avoiding unnecessary decryption and preventing a denial-of-service attack. The transmission apparatus that establishes a secure communications channel (SA) between the transmission apparatus and a reception apparatus includes a creation section that creates a packet, an encryption section that, based on a ratio of a redundant packet to the packets created by the packet creation section and on an instruction from the reception apparatus, determines an encryption coverage in the created packet and encrypts data in the encryption coverage, and a transmission section that transmits the encrypted packet through SA.
