Text steganography is part of information hiding that focuses on concealing sensitive data within seemingly innocuous textual content. The feature-based method, which hides the hidden message based on the distinctiveness of each letter in the text, is taken into consideration in this research as a method categorization for text steganography. It integrates the three tecniques into a feature-based method that creates stego text utilising a single bit concealing mechanism in each letter. This paper introduces the three techniques single bit framework for feature-based method of text steganography within the Unified Model Language (UML). The UML that is represented diagram such as use case diagram, sequence diagram and class diagram. This UML representation of technique of feature-based method as the visualization in developing of text steganography in conceal the hidden message based on embedding and extracting implementation.
