Abstract

The technology development doesn’t only give convenience to every side, but also inflicts problem, especially in the process of message security. Message security can be applied through steganography by hiding the message. The steganography is a security techniques by inserting message to the other place. The Least Significant Bit method and End Of File method are the two methods that are popular enough to be used. In this research, using the combination of these two methods, where a message will be divided into two parts, the first part is hidden using the Least Significant Bit method, and the second part using End Of File method for the purpose to increase the security in keeping secrecy of the sent messages. The final result of this research is a program that can be applied to secure txt messages file format to the PNG image file format.
