The　core　of　this　article　is　based　on　application　behavior　declaration,　using　the　＇words　match　deeds＇　as　the　standard　of　judgment,　comparing　＇words＇　with　＇lines＇,　and　then　using　the　implicit　indicator　model　to　calculate　the　credibility　of　the　behavior.　This　paper　presents　the　concept　of　action　path　of　application　behavior,　the　definition　of　three　types　of　program　event,　the　recessive　parameter　model　and　the　concept　of　credibility-degree　calculation.　It　provides　a　new　idea　for　the　research　of　credible　Verification　method.　©　2019,　Springer　Nature　Singapore　Pte　Ltd.
