Abstract
Description
1.オーディオビジュアル信号をあるサイズのブロック、例えば64×64ピクセルに分割するステップと、
2.各々のブロックについて何らかのサインビットを生成するステップと、
3.上記サインビットを該サインビットが生成されたブロックに埋め込むステップと、を有している。
本発明の他の実施形態が、図4に示されている。サインをオーディオビジュアル信号401に埋め込むためのコンピュータ読み込み可能な媒体400は、フラット領域を含んでいる。オーディオビジュアル信号401は、プログラムモジュール410によって画像ブロックに分割され、命令をプロセッサ402に与える。サインビットは、プログラムモジュール410で作成された画像ブロックに関する他のプログラムモジュール420において得られる。その後、プログラムモジュール430によって計算された全てのブロックの複合サインビットを埋め込むことによるプログラムモジュール440によって、ウォーターマーキングスキームが実施される。
法の執行、証拠イメージング若しくは指紋に関するような防犯カメラ又は監視カメラ、
遠隔医療システム、医療スキャナ若しくは患者の書類作成のような健康管理システム、又は
自動車保険、損害保険及び健康保険のような保険書類作成を含んでいる。
