Abstract
Privacy, especially in a cellphone, is an important thing and should be protected. Steganography is a methodused to protect a sensitive information. The issue tried to be discussed in this study is the issue on inserting technique in a text through a simple method of White Space Steganography on android. The inserted message has been compressed through a double compression method by using LZW and Huffman so that the size of message to be inserted can be minimized while the capacity of the inserted message can be minimized. The compression shows that the compression ratio much depends on the type of text input to the text to be sent; the more the repetition or duplication found on the message, the smaller the compression ratio will be. The compression process using Android based smartphone is relatively fast with the average duration of 0.045 seconds, either for the insertion or extraction.
