Week 5

Password implementation was completed.
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.

Week 4

Graphical User Interface has been implemented. Below we present a preview of how it looks like.

Even though there still are some bugs and errors generate by unknown causes, we are managing to 'fix' them by closing certain parts of the program after the code execution and before it starts to do things that were not meant to happen like printing out on the matlab terminal the whole content of our matrix

Password implementation is the next milestone for our project.
