Noble Method for Data Hiding using Steganography Discrete Wavelet Transformation and Cryptography Triple Data Encryption Standard: DES

Abstract

Noble method for data hiding using steganography Discrete Wavelet Transformation: DWT and cryptography triple Data Encryption Standard: DES is proposed. In the current era, information technology has become inseparable from human life, especially regarding the processing and dissemination of information. In line with advances in information technology, there are also parties who want to abuse such information by changing information or even damage it. To avoid that happening, then the data needs to be secured first into other media using the DWT method. The choosing of this method is because the image of the data insertion almost resembles the original image. Triple DES methods are also required to encode data and provide additional security so that hidden data will be difficult to solve. The choosing of this method is because it is resistant against brute force, chosen plaintext, and known plaintext attack. Based on the test, image insertion results in 100% immune to the image manipulation of brightness and contrast, but not so resistant to cropped, resized, and rotated image manipulation. Other tests also indicate that the data which is in the picture can be extracted again and will not undergo any changes.
