摘要： A method and system for manipulating or modifying identifiable objects in a standard broadcast or Internet-based multimedia stream according to a control specification and a content specification. Viewers and/or organizations can independently specify acceptable levels of content on multiple dimensions to satisfy the content specification while minimizing the filtering or blocking to the viewers. A “fuzz ball” control specification is provided for masking some portion of a video frame. Several fuzz ball specifications can be overlaid to address multidimensional content specifications or rating systems. The manipulation of the multimedia stream can take place at the client (set-top box or computer), intermediate node, the content server or a combination thereof. Proxy servers can modify content specifications for outgoing requests, enabling organizations to specify intranet-wide policies. Multicasting can be supported by using a single stream delivered to multiple clients, each modifying the video using a different specification. The specification to facilitate modification can be done at different granularity levels: the video, a group of frames, or individual frame level and can also be time-based. Various protocols can be used to provide the content and/or control specification, including the VBI of a standard broadcast, PICS, RTSP and MPEG protocols.

摘要： A multimedia stream is multicasted. A request to perform the multicast is received. A plurality of distribution nodes are assigned to provide the multicast to a plurality of receivers. The assignment of a node is based on the transformation capabilities of that node. The multicast is then performed and the assigned node performs its transformation. The transformed multicast is distributed to a receiver which is suitable for receiving the transformed multicast.

摘要： Improved privacy preservation techniques are disclosed for use in accordance with data mining. By way of example, a technique for preserving privacy of data records for use in a data mining application comprises the following steps/operations. Different privacy levels are assigned to the data records. Condensed groups are constructed from the data records based on the privacy levels, wherein summary statistics are maintained for each condensed group. Pseudo-data is generated from the summary statistics, wherein the pseudo-data is available for use in the data mining application. Principles of the invention are capable of handling both static and dynamic data sets

摘要： Techniques are disclosed for aggregation in uncertain data in data processing systems. For example, a method of aggregation in an application that involves an uncertain data set includes the following steps. The uncertain data set along with uncertainty information is obtained. One or more clusters of data points are constructed from the data set. Aggregate statistics of the one or more clusters and uncertainty information are stored. The data set may be data from a data stream. It is realized that the use of even modest uncertainty information during an application such as a data mining process is sufficient to greatly improve the quality of the underlying results.
