One of the main aspects on embedding process of any text steganography methods is the
capacity text.It is because a better embedding ratio and saving space offers; a more text can be hidden.This study tries to evaluate several format based techniques of
text steganography based on their embedding ratio and saving space capacity.Thus, the main objective of this study is to analyze the performance of text steganography methods
which are Changing in Alphabet Letter Patterns
(CALP), Vertical based and Quadruple methods
based on these two capacity factors.It has been identified that vertical based method give a good effort performance compared to CALP and Quadruple based method.In future, a robustness of text steganography methods should be considered as a next effort in order to find a strength capability on text steganography
