検出方法および検出装置
Document Type and Number:
Japanese Patent JP4893643
Kind Code:
B2
Abstract:
Data to be embedded is divided and thus embedded in areas internal to a block corresponding to a predetermined region of a scanned image. Of the areas, a defined area has the embedded data's identification information embedded therein. A detection apparatus includes a counter including a region including a region storing identification information and a region storing a count value corresponding to embedded data divided that is detected in an area other than the defined area, and classifies a count value corresponding to embedded data divided that is detected from a scanned image for each identification information detected in the block, and stores it to the counter. The detection apparatus identifies data stored for each identification information that has the largest count value for each area as data embedded in that area, and reconstructs the embedded data.
