- Abstract
This study uses the technique of incognito data and information into a container in the form of images combined with the addition of the password by using the method of Least Significant Bit (LSB) and the technique of Haar Wavelet. Testing the system by sending a message in the form of a text file and an image file with the process of the original image are transformed to wear haar wavelet divided into four zones of frequency, namely LL, LH, HL, and HH. Where Bitbit Readings are planted in a zone LL and attempted insertion of the bit of the file reading into the last bit in each byte of the image file and can show you back the results of the message. The research results, i.e., images processed by the LSB and Haar Wavelet method, do not change the file size, resolution, dpi, and physical form image. The advantage of this method is very simple computing, oriented computers, which need less space to store and are time-efficient.
