Hi Rio,

You could do the following to save your data and ensure no-one intercept or reads your data.

Firstly you don't need a secure site to hide you confidential data. You hide your confidential data in plain sight.

You will need a security application called Steganos Security Suite Centre and iTunes on your PC.

By using Steganos File manager you can encrypt your data files and hide them it what is called a carrier file.

For example say you have a list of files you want to make secure, you would drag and drop into the Steganos Security file manager window. Any file will do but care has be made to ensure that the file are resonably small. i.e. try and keep the file list total under a few MB. This shouldn't be too difficult for all your crucial documents if using grey scale jpeg compression from scanned documents.

Once you have all the documents listed in the file manager you would then select to close the file manager. The file manager would then ask if you want to encrypt and hide the files. It will then ask you to select a carrier file. The carrier file can be a .WAV or .BMP file which is generally much larger than the encrypted file to be hidden. I generally select a .WAV file. The smaller encrypted file is then embedded/hidden into the .WAV (Music Track) file after entering the encryption password.

This is done by EORing the LSBs of the PCM stream of the .WAV file. i.e embedding the encrypted file (white noise) into the noise floor of the music. The music file will play as normal without any noticeable effects on the music sound quality. (although the SNR will be slightly affected) Therefore your encrypted files are now buried in a plain sight file. The carrier .WAV file can now be uploaded to your personal web space, ftp server, ipod etc and only you will know it is a carrier file hidding in plain sight an encrypted set of files.

This will take care of everybody except possibly the government who may be interested in any of your personal data, thats of course if they are interested.

Steganos Security makes things easy for the goverment to detect the carrier file by adding some header data on to the front end of the file. To lose this header information you need iTunes and its Apple lossless encoder. Just use this lossless encoder on the imported carrier .WAV file to create an Apple lossless encoded version. This will change the file format and detection of the header info on the carrier .WAV file much more difficult.

Save this itunes music file to your iPod or upload to your ftp server etc.

To get your encrypted files back just reverse the process. Convert the Apple Lossless encoded music back to a .WAV file using iTunes then open the carrier .WAV file with Steganos Security's File manager, enter the encrytion password and your data will reappear. Just Drag and drop from the file manager back into your desktop screen.

PGP is good but the problem is that the encrypted file has the extention .PGP which is an open invitation for someone to crack. The government can easily crack PGP files.
