Information which has a recursive characteristic in the process of transmission is generated because its information elements are continuously lost. By using P-sets which is a new mathematic tool and has dynamic characteristics, the concept of inwardrecursion information is proposed, and the structure of inward-recursion is given. Theorems are obtained such as the sequence theorem of inwardrecursion information, the merging theorem of loss information, identification and recovery theorems of inwardrecursion information. By defining the modulus and the identification measure on inwardrecursion information, the numerical value methods of identification and recovery are obtained. Also, the identification criterion of inwardrecursion information is given. Finally, the application of identification and recovery is presented.
