Abstract

This paper was carried out on the basis of the need for data security on digital media in the form of methods that can help secure confidential data so that confidential data can only be read by the desired person and to anticipate that the data is not read by unauthorized persons. This paper suggests the use of steganography techniques in securing messages, where confidential messages will be inserted into the cover image. The method in this paper uses a combination of two methods, namely the Huffman method for data compression and the Least Significant Bit (LSB) method as a method in Steganography. The Huffman method is used to compress the data before it is inserted into the cover image so that it can reduce the size of the data to be inserted, and the resulting stego image does not change significantly. The results of the experiments carried out, message insertion without using Huffman compression, resulted in an average MSE value of 1.25 and an average PSNR value of 42.35. Meanwhile, the results of the combination of LSB and Huffman compression methods can produce an average MSE value of 0.37 and an average PSNR value of 53.96.
