Abstract

Rapid technological developments and fast data transmission in communication networks can experience
tapping data from parties not concerned. Message sending uses Electronic Messages (EMAIL) make it easier for users in
terms of efficient time use, data transmission activities in data communication challenges the user in securing
information that is possessed in transmitting data to be safe and protected by confidentiality. In this study, the technique
of steganography is a security technique for hiding confidential information in other media that seems meaningless,
except for people who understand the key. Steganography Technique The Least Significant Bit (LSB) method allows to
store 1 bit of data in each primary color which means it can store 3 bits of data symbols in each pixel. By entering
characters (messages) and images as media cover, encode the image and then send it by email from the SMTP protocol.
Email recipients decode steg-image files to see the characters (messages) inserted. The results of the research carried out
by the system on the 99x57 resolution web browser can accommodate 2116 characters. The initial image of the hex value
shows a lot of free space, but after encoding the hex value the image becomes full because a message has been inserted.
