In this paper, the product form of semantics from the user in the form of symbolic elements of cognitive psychology, analyzes the research on the product form the user requirements and preferences of semantics to arrive at product design modeling symbolic elements of the semantic use of the general laws, and through real cases analysis of the derived rules for authentication, reached its feasibility, so as to product form of cognitive semantics to contribute.
