Combination of Steganography with K Means Clustering and 256 AES Cryptography for Secret Message

摘要

Steganography is a technique that evokes secret messages on the media. The cover requested for the message does not arouse suspicion, while cryptography is a senior art and science that maintains the confidentiality of data. Least Significant Bit (LSB) is one of the steganography methods for hiding secret messages carried out at the last bit in several bytes of media dataset values. The location of LSB embedding in the image cannot be randomized. This makes the location of the message that will be inserted (embedding) easier to detect which results in a decrease in the quality of the results of steganography and the similarity of the data inserted. To overcome the weaknesses of the LSB steganography method, improve the K Means Clustering method on steganography and AES 256 for message security. Grouping is a method that is carried out to select the object area, then the embedding of the message is done on the object obtained. As additional security, cryptography used is AES 256.
