摘要： Methods and apparatuses are provided for facilitating group access controls in peer-to-peer or other similar overlay networks. A group administrator may create a group in the overlay network and may assign peer-specific certificates to each member of the group for indicating membership in the group. A group member peer node can access data objects in the overlay network using its respective peer-specific certificate to authenticate itself as a group member. The authentication is performed by another peer node in the network. The validating peer node can authenticate that the group member is the rightful possessor of the peer-specific certificate using a public key associated with the peer node to which the peer-specific certificate was issued. The validating peer node can also validate that the peer-specific certificate was properly issued to the group member using a public key of the apparatus that issued the peer-specific certificate.

摘要： Techniques are provided to improve identification of a person using speaker recognition. In one embodiment, a unique social graph may be associated with each of a plurality of defined contexts. The social graph may indicate speakers likely to be present in a particular context. Thus, an audio signal including a speech signal may be collected and processed. A context may be inferred, and a corresponding social graph may be identified. A set of potential speakers may be determined based on the social graph. The processed signal may then be compared to a restricted set of speech models, each speech model being associated with a potential speaker. By limiting the set of potential speakers, speakers may be more accurately identified.

摘要： Techniques are provided to recognize a speaker's voice. In one embodiment, received audio data may be separated into a plurality of signals. For each signal, the signal may be associated with value/s for one or more features (e.g., Mel-Frequency Cepstral coefficients). The received data may be clustered (e.g., by clustering features associated with the signals). A predominate voice cluster may be identified and associated with a user. A speech model (e.g., a Gaussian Mixture Model or Hidden Markov Model) may be trained based on data associated with the predominate cluster. A received audio signal may then be processed using the speech model to, e.g.: determine who was speaking; determine whether the user was speaking; determining whether anyone was speaking; and/or determine what words were said. A context of the device or the user may then be inferred based at least partly on the processed signal.

摘要： Methods and apparatuses are provided for facilitating data access controls in peer-to-peer or other similar overlay networks. A peer node storing a data object may receive a request for access to the stored data object, and may locate in the network an access control list associated with the data object using a routing mechanism included in the data object. The peer node may determine whether the requested access is authorized based on the access control list, and may grant or deny access based on the determination. A peer node storing an access control list may receive a request from a peer node storing a data object for information relating to access controls associated with the data object. The peer node storing the access control list may then send the requested information relating to the access controls associated with the data object.

摘要： A position estimate for a mobile device is generated using data from motion sensors, such as accelerometers, magnetometers, and/or gyroscopes, and data from light sensors, such as an ambient light sensor, proximity sensor and/or camera intensity sensor. A plurality of proposed positions with associated likelihoods is generated by analyzing information from the motion sensors and a list of candidate positions is produced based on information from the light sensors. At least one of the plurality of proposed positions is eliminated using the list of candidate positions and a position estimate for the mobile device is determined based on the remaining proposed positions and associated likelihoods. The proposed positions may be generated by extracting features from the information from the motion sensors and using models to generate likelihoods for the proposed positions. The likelihoods may be filtered over time. Additionally, a confidence metric may be generated for the estimated position.

摘要： A method for transmitting a packet from a transmitting node to a destination node in a communication network can enable improved network efficiency. The method includes receiving and storing identification information concerning at least one foreign node that is directly reachable in the communication network (block 505). It is then determined, using the identification information, whether the destination node is directly reachable in the communication network (block 510). Based on whether the destination node is directly reachable in the communication network, it is then determined whether to transmit the packet to the destination node using a tunneling protocol or without using a tunneling protocol (block 515). The packet is then transmitted from the transmitting node to the destination node (block 520).

摘要： A method for using Internet mobility protocols with non Internet mobility protocols is described. A first gateway node communicates with a second gateway node using a first protocol. The first protocol is a non Internet mobility protocol. A home address (HoA) for a mobile node is managed by the second gateway node. Updates regarding the location of the mobile node within a domain are received using a second protocol. The second protocol is an Internet mobility protocol. Intra-domain mobility for the mobile node is managed by the second gateway node using the second protocol.

摘要： In an AR system, method for operating same, a mobile device, and method for operating same, flexible loxels are used that may be different for different image data providers. This enables AR applications to download smaller loxels which have more information, such as dense areas, like in cities, or larger loxels which have less information, like, for example, desert areas. Data downloads may take into account client orientation and direction of motion to determine incremental data that need to be downloaded as the client moves. The loxels are coded with loxel identifiers mapped to location information, so only the necessary loxels for a particular application need be downloaded, allowing the client to autonomously decide when to acquire new image data and how much data to acquire.
摘要翻译：在AR系统中，使用对于不同的图像数据提供者可能不同的用于操作的方法，移动设备和用于操作相同的柔性loxels的方法。这使得AR应用程序可以下载更多的信息，比如密集区域，比如在城市中的较小的loxels，或者具有较少信息的较大的loxels，例如沙漠地区。数据下载可能会考虑到客户端方向和运动方向，以确定需要在客户端移动时下载的增量数据。使用映射到位置信息的loxel标识符对loxel进行编码，因此只需要下载特定应用程序所需的loxels，从而允许客户端自动决定何时获取新的图像数据以及获取多少数据。

摘要： A communication system enables a node to utilize multiple communication interfaces to connect to an overlay network. The use of multiple communication interfaces provides a redundant overlay network connection, thereby enabling a node to maintain connectivity or select a preferred connection to the overlay network, increasing efficiency or reducing costs in the overlay network. A network in which member nodes obtain services in the absence of server-based infrastructure is referred to as a “peer-to-peer overlay network” (or “overlay network” or simply “overlay”). Overlay networks consist of several nodes from hundreds, to thousands, joined together in a logical routing structure. Individual nodes often participate in routing and maintenance aspects of the overlay. Typically an overlay is formed through the enrollment and joining of all these nodes as defined by the overlay protocol. Nodes forming peer-to-peer overlay networks may communicate with each other over various network technologies.

摘要： Methods and apparatus for publishing services and performing queries for service in a network are described herein. Service descriptions writing in a native search description language are translated to a normalized schema. The normal schema is published to the network. Queries to the network, which may be written in any native search description language, are also translated to normalized schema prior to performing the search. Accordingly, all services available can be published and located in a query without consideration of the native search description language.
