Rapid development in mobile phone technology recently has caused the emergence of smart phones with many different features, and a complex operating system just like a computer. One of well known operating system for mobile phones is android. Nonetheless, although these new technology of smart phones have many features, people seems still has a special attention to an old-fashioned text service, which is Short Message Service, better known as SMS. Unfortunately, SMS feature nowadays still has limitations. Especially regarding the safety of confidential information. In other word, the ability of someone in sending a confidential information through SMS is still in question. In order to solve this kind of problem, authors will try to create an application that capable to secure a confidential message. Security system that author offered is based on two security models, namely encryption and steganography security. Before being sent, a message will firstly encrypted using the Caesar cipher algorithm, and then inserted into the SMS text messages using the algorithm whitespace. Next, an access to the message in the application must be secured with a password, so the message will be safe from unauthorized parties. The research methodology used in this research is the development of the operation system. The research steps is begins with library study, identifying system requirements, data collection, system requirements, and system development methods. Then, finally, this research will able to create an applications that will be installed on Android-based smart phones. This application can do the Caesar cipher encryption algorithm, and will hide it in a text message or SMS. The results of encryption and steganography process to the message is also can be decrypted through this application by entering a preceding password. Keywords: encryption, steganography, information security, whitespace, Caesar cipher.
