Abstract: A system and method for providing a functional virtual environment with real time extracted and transplanted images. The system includes hardware and software for providing a multi-dimensional computer generated environment and for receiving a plurality of extracted video images. The system is adapted to transplant the extracted video images into the environment in a manner that preserves the virtual metaphor thereof. In the illustrative embodiment, a realistic virtual city is created in accordance with the Virtual Reality Modeling Language (VRML) protocol. The extracted images are transplanted onto an object in the environment as a texture. In the best mode, the object is invisible. The extracted video images are streamed continuously into the environment such that a live real time interaction is enabled. The environment is networked and the system is adapted to receive multiple simultaneous streams which are transplanted and exported to enable a virtual community.  Within the community, users seated in their native environment, appear to walk when navigating due to the unique teaching of the present invention by which a series of stored extracted images of the user walking are transplanted into the environment and replayed for so long as the user is navigating. A separate series is displayed to each person within a predetermined range of the walker that has the walker in his field of view depending on the viewing angle of the observer. A master copy of the environment is stored on a server and downloaded to each client on the network as part of a setup process.  Thereafter, local changes in the environment are uploaded to the server and subsequently downloaded to selected clients as updates. The environment will support private areas and the system is adapted to allow extracted video streams within private environments to be sent to each person in the private environment directly, bypassing the server.

IPC: H04L9/00
Filed: 2005-11-11
Abstract: Improper re-use of a static Difhe-Hellman (DH) private key may leak information about the key. The leakage is prevented by a key derivation function (KDF), but standards do not agree on key derivation functions. The module for performing a DH private key operation must somehow support multiple different KDF standards. The present invention provides an intermediate approach that neither attempts to implement all possible KDF operations, nor provide unprotected access to the raw DH private key operation. Instead, the module performs parts of the KDF operation, as indicated by the application using the module. This saves the module from implementing the entire KDF for each KDF needed. Instead, the module implements only re-usable parts that are common to most DFs.Furthermore, when new KDFs are required, the module may be able to support them if they built on the parts that the module has implemented.
