Abstract

Rapid technological developments and fast data transmission in communication networks can experiencetapping data from parties not concerned. Message sending uses Electronic Messages (EMAIL) make it easier for users interms of efficient time use, data transmission activities in data communication challenges the user in securinginformation that is possessed in transmitting data to be safe and protected by confidentiality. In this study, the techniqueof 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 tostore 1 bit of data in each primary color which means it can store 3 bits of data symbols in each pixel. By enteringcharacters (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 outby the system on the 99x57 resolution web browser can accommodate 2116 characters. The initial image of the hex valueshows a lot of free space, but after encoding the hex value the image becomes full because a message has been inserted.
