Patent CA-2438180-A1 (CA)
Inventor: ERICKSON ROGER D
IPC: H04L9/12
Filed: 2002-02-08
Abstract: The invention provides a method and apparatus for transmitting data securely using an unreliable communication protocol, such as User Datagram Protocol. In one variation, the invention retains compatibility with conventional Secure Sockets Layer (SSL) and SOCKS protocols, such that secure UDP datagrams can be transmitted between a proxy server and a client computer in a manner analogo us to conventional SOCKS processing. In contrast to conventional SSL processing , which relies on a guaranteed delivery service such as TCP and encrypts successive data records with reference to a previously-transmitted data record, encryption is performed using a nonce (504) that is embedded in each transmitted data record (507). This nonce acts both as an initialization vector for encryption/decryption of the record, and as a unique identifier t o authenticate the record. Because decryption of any particular record does no t rely on receipt of previously received data record, the scheme will operate over an unreliable communication protocol.

Patent CA-2446134-A1 (CA)
Inventor: SEJNOWSKI TERRANCE
IPC: G06V10/56
Filed: 2002-04-30
Abstract: A method and apparatus for efficiently encoding images using a set of non-orthogonal basis functions, thereby allowing reduction of file size, shorter transmission time, and improved accuracy. The non-orthogonal basis functions include homogenous color basis functions, luminance-encoding basis functions that have luminance edges and chromatic basis functions that exhibit color opponency. Some of the basis functions are non-orthogonal with respect to each other. Using these basis functions, a source vector is calculated to provide a number of coefficients, each coefficient associated with one basis function.  The source vector is compressed by selecting a subset of the calculated coefficients, thereby providing an encoded vector. Because the method is highly efficient, the image data is substantially represented by a small number of coefficients. In some embodiments, the non-orthogonal basis functions include two or more classes. A wavelet approach can also be utilized.
