Digital security is a growing field of study in various areas of science, which includes stega-
nography - the art of writing in a hidden manner - as one of the new research areas. This
undergraduate thesis presents the implementation of a Least Significant Bit (LSB) steganographic
technique to embed text messages in image files. The study is based on literature research on
data hiding techniques in digital images and the importance of using watermarking as a measure
of protection against piracy and image forgery. The paper presents the theoretical concepts
involved in the LSB technique, as well as the methods and tools used for the insertion of the
digital watermark. The results obtained from tests conducted prove the effectiveness of the LSB
technique in securely and efficiently embedding digital watermarks in digital images.
