See below the section of our image where we are currently hiding information regarding the password as well as additional information used in the decryption process.
This is the bottom right corner of our output image containing the hidden image. These few modified pixels are virtually unnoticeable with the naked eye, but some software specially designed to detect suh anomalies might pick it up.
We encountered several problems with passing data from GUI functions to other GUI functions or other matlab functions and so we decided to take the quick solution and not complicate the software further and risk damaging it and we decided to write sensitive information imputed in the GUI functions to a file; the file would be read by other functions immediately (for the purpose of either hiding the data in the image or confirm that the data is the same as the one found in the image) and then deleted.
