We develop an agency contract system that protects personal information of the contractor and information to confirm intention to contract by background texture watermarks. When the contractor carries an application form, it may be folded, rumpled or waved little. In this case, contractor's information must be recognized from background watermarks printed on the application form. But it cannot be recognized surely folded, rumpled or waved application form by the conventional method. In this paper, we propose a new recognition of watermark dot information from folded, rumpled or waved application form. The new recognition is composed of crooked point sequence recognition expressing character borders by searching around calculated point, and dot recognition by shading folded, rumpled or waved paper and emphasizing dot in luminosity from this paper. As a result, we got correct recognition ratio of more than 99% from folded, rumpled or waved paper.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e本誌: \u003c\/strong\u003e\u003ca href=\"\/products\/ieej-rc13510\"\u003e電気学会論文誌C（電子・情報・システム部門誌） Vol.135 No.10 （2015） 特集：産業界を支える情報通信技術\u003c\/a\u003e\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e本誌掲載ページ: \u003c\/strong\u003e1279-1287 p\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e原稿種別: \u003c\/strong\u003e論文／日本語\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003e電子版へのリンク: \u003c\/strong\u003e\u003ca target=\"_blank\" href=\"https:\/\/www.jstage.jst.go.jp\/article\/ieejeiss\/135\/10\/135_1279\/_article\/-char\/ja\/\"\u003ehttps:\/\/www.jstage.jst.go.jp\/article\/ieejeiss\/135\/10\/135_1279\/_article\/-char\/ja\/\u003c\/a\u003e\u003c\/p\u003e","brand":"IEEJ-P10","offers":[{"title":"冊子印刷（一般価格770円\/会員価格550円） \/ A4 \/ 9","offer_id":46349473906927,"sku":"IEEJ-RC13510-017-PRT","price":770.0,"currency_code":"JPY","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0718\/9512\/2159\/files\/IEEJ-RC13510_24d29dbe-6a90-4de3-9cc5-c6808286f2d0.png?v=1747382592","url":"https:\/\/ieej.bookpark.ne.jp\/products\/ieej-rc13510-017","provider":"電気学会 電子図書館","version":"1.0","type":"link"}
