Abstract

Communication by using email has become frequent nowadays and creates a new medium for hiding secret data. Email Header Steganography or HeadStega is a technique in Noiseless Steganography that utilizes the header part of an email such as subject, to, cc, etc. to hide secret messages. HeadStega does not produce noise in data and the body of email remains legitimate. However, HeadStega has a low hiding capacity. A recipient’s email address only able to hide 4 to 11 bits of secret message. This paper propose a new technique to improve the hiding capacity of HeadStega especially in the ‘to’ field of an email. By using LZW compression algorithm and modifying the message-hiding process, the capacity of HeadStega can be improved. The experiment results show that HeadStega hiding capacity increased by 39.72% for text message and increased by 58.80% for binary messages.
