A data storage system filter operates through a filter framework in a file system to detect and provide customized responses to unauthorized access attempts. A security event definition determines when file system access events are classified as unauthorized access attempts. A trap manager manages the security events, and causes traps to be installed to capture file system responses. The trapped responses can be replaced with customized data, such as static artificial data, or artificial data generated based on a context of the request and / or response. The security filter can be loaded or unloaded in the filter framework and operates on a callback mechanism to avoid significant disruption of I / O activity.

A method of reducing spatial noise in an image. Low-pass (smoothing) filters are calculated simultaneously from three successive image rows. Three blocks (m1, m2, m3) are associated with the three successive image rows, and the blocks are processed in row-major order. This implementation is applicable to both luminance and chrominance. The number of smoothing parameters is reduced to one. The technique is applicable to both luminance and chrominance. Directional mapping is used. Extension of the technique to spatial filtering using a 5×5 neighborhood (using five successive image rows) is described. Embodiments of the method using the MMX instruction set are described.

A system and method for establishing a SIP session between calling and called end-points. A SIP server receives a SIP INVITE request for establishing the SIP session. The SIP INVITE request includes standard routing information in its header. The SIP server receives the SIP INVITE request and responds by transmitting to the calling end-point a HTML link associated with a web server. In rendering the contents of the HTML link, the calling end-point transmits an HTTP request to the web server including voice cookie information. The voice cookie information may include information gathered about the caller such as the caller profile information, transaction information, caller intent information, or recent and past history associated with a web site domain. The web server forwards the voice cookies to the SIP server. The SIP server determines an address of the called end-point as a function of the routing information in the SIP INVITE request and the voice cookie information. The call is then routed to the determined address along with the voice cookies or information derived from the voice cookies. New voice cookies may be written to the web server which transmits these to the calling end-point within an HTTP response.
