Model for Data Hiding Using Steganography

Abstract

Steganography is a technique to secure a data communication. Data form Message, secured by inserting message bits into carrier bit files. One of Method for inserting messages in carrier files is the Least Significant Bit method. Inserting the message bits in the carrier bit file bit. Generally, this report discussed designing of steganography applications that modified 2 bits of carrier file using LSB Method. There was some testing to be performed on this application, such as embedding and retrieving process testing to know functionality application, capacity testing to know cooperation carrier sizes before and after message embedded, and quality testing by using PSNR formula to know stegano file quality. Testing conducted includes testing the sending and receiving messages that have been inserted message. From the test, it can be concluded that the data PIN (Personal Identifier Number) inserted cannot be opened by unauthorized parties and accepted banking customers when receiving an ATM card or credit card.
