摘要： The claimed subject matter relates to architectures and/or mechanisms that can facilitate issuing, embedding and verification of an optical DNA (o-DNA) signature. A first mechanism is provided for obtaining a set of manufacturing errors inherent in an optical media instance. These errors can be encoded into the o-DNA that can be cryptographically signed with a private key, then embedded into the source optical media instance. A second mechanism is provided that can decrypt the o-DNA with a public key and compare the authenticated errors to the observed errors to ascertain whether the optical media instance is authentic as opposed to a forgery or counterfeit.

摘要： Human body motion is represented by a skeletal model derived from image data of a user. Skeletal model data may be used to perform motion recognition and/or similarity analysis of body motion. An example method of motion recognition includes receiving skeletal motion data representative of a user data motion feature from a capture device relating to a position of a user within a scene. A cross-correlation of the received skeletal motion data relative to a plurality of prototype motion features from a prototype motion feature database is determined. Likelihoods that the skeletal motion data corresponds to each of the plurality of prototype motion features are ranked. The likelihoods are determined using the cross-correlation. A classifying operation is performed on a subset of the plurality of prototype motion features. The subset of the plurality of prototype motion features is chosen because its members have the relatively highest likelihoods of corresponding to the skeletal motion data.

摘要： Human body motion is represented by a skeletal model derived from image data of a user. The model represents joints and bones and has a rigid body portion. The sets of body data are scaled to a predetermined number of sets for a number of periodic units. A body-based coordinate 3-D reference system having a frame of reference defined with respect to a position within the rigid body portion of the skeletal model is generated. The body-based coordinate 3-D reference system is independent of the camera's field of view. The scaled data and representation of relative motion within an orthogonal body-based 3-D reference system decreases the data and simplifies the calculations for determining motion thus enhancing real-time performance for multimedia applications controlled by a user's natural movements.

摘要： A human interactive puzzle (HIP) authorization architecture where keyed and animated puzzles are executed by HIP players which are distinct and obfuscated to the point where breaking a single player is a relatively costly operation. A key is created in response to a request for a service, a HIP player is created based on the key, and a small installation executable is created that expands during installation to produce a computationally expensive data structure on the client relative to verification of the solution at the server. Thus, copying of the player or relay of the puzzle to a third system requires more time than allowed to receive the solution at the server.

摘要： A data center includes a plurality of computing units that communicate with each other using wireless communication, such as high frequency RF wireless communication. The data center may organize the computing units into groups (e.g., racks). In one implementation, each group may form a three-dimensional structure, such as a column having a free-space region for accommodating intra-group communication among computing units. The data center can include a number of features to facilitate communication, including dual-use memory for handling computing and buffering tasks, failsafe routing mechanisms, provisions to address permanent interface and hidden terminal scenarios, etc.

摘要： Functionality is described for reducing the unauthorized reproduction of optical media, such as optical discs of various types. The functionality operates by adding a physical descriptor to an optical medium, forming reference descriptor information based on the descriptor, signing the reference descriptor information to produce authenticity information, and adding the authenticity information to the optical medium. At a point of consumption, the functionality operates by reading the authenticity information and reading the descriptor. Based on the information that is read, the functionality performs cryptographic analysis and descriptor-based analysis to validate the optical medium. The functionality includes various provisions to reduce the impact of wear and tear on the above-summarized analysis. The functionality can be applied to stamped or recordable optical media.

摘要： A beat analysis module is described for determining beat information associated with an audio item. The beat analysis module uses an Expectation-Maximization (EM) approach to determine an average beat period, where correlation is performed over diverse representations of the audio item. The beat analysis module can determine the beat information in a relative short period of time. As such, the beat analysis module can perform its analysis together with another application task (such as a game application task) without disrupting the real time performance of that application task. In one application, a user may select his or her own audio items to be used in conjunction with the application task.

摘要： Exemplary systems and methods implement an exemplary visual perception model. This model can be implemented in such applications as imaging, compression, denoising, annotation of hi-fidelity images, etc. In one implementation a perceptual filter estimates an entropy statistic and a standard deviation statistic associated with each pixel of an image, then mixes the entropy statistic and the standard deviation statistic to map an estimation of human perceptual tolerance to noise or alteration in parts of the image. In one application, metadata may be added to an image via a system of synergistic watermarks, in which the watermarks strengthen each other and are placed according to the noise tolerance of the pixels in order to maintain hi-fidelity of the image.
