Emoticon-based steganography for securing sensitive data

Transferring information between nodes in this digital era has been made it easy for users to communicate. Sensitive data, however, requires protection during transmission to prevent unauthorized users from exploiting it. In this paper, we propose to hide secret data by developing emoticon-based steganography. Here, the data is embedded to the emoticon which is sent along with the cover text via chatting. The experimental result, which is obtained from various types of data, depicts that this proposed method, in general, has higher performance than that of existing one. That is, each emoticon has been able to dynamically hold more information. Specifically, the method without preprocessing is better.
