IPC: H04N21/2389
Filed: 2004-04-23
Abstract: <P>PROBLEM TO BE SOLVED: To provide a system for preventing video that is shot and recorded in real time, from being authenticated and forged.  <P>SOLUTION: In the method for embedding and detecting a watermark with which the watermark is embedded and detected in shot digital video in real time to confirm whether or not the video is forged and a forged position, the watermark is produced by using a quantized coefficient after frequency conversion that is used for a compression step, and the watermark is embedded in the video, thereby compressing the video and embedding the watermark together. A strong watermark embedding method is disclosed to embed a random sequence resulting from circularly shifting an original pseudo random sequence just for a distance (d), as a watermark in the video. Technology is disclosed to generate and embed the water mark using a quantized DCT coefficient in the video MPEG compression step, and the watermark can be generated and embedded for the unit of a macro block or for the unit of a slice.  <P>COPYRIGHT: (C)2005,JPO&NCIPI

Abstract: <P>PROBLEM TO BE SOLVED: To provide a system and a method for managing logical versions of a file system made through a near-instantaneous copy process.  <P>SOLUTION: Each logical version of the file system, including a primary version, is assigned a unique epoch number or other identifying value, and each file system object is assigned two epoch numbers that define a space of logical versions for which the object exists. A list of all valid epoch numbers are maintained in a version table. The near-instantaneous creation of a logical version of the file system requires inserting a unique epoch number entry in the version table and the next epoch number to the new logical version. An original state of the system is preserved through the use of a copy-on-write procedure for file system objects that are reference by that logical version of file system. Accordingly, new logical versions of file systems are maintained and original states of previous states of the logical versions of file systems are preserved.  <P>COPYRIGHT: (C)2005,JPO&NCIPI
