We can also look at things like allowing people to encrypt data that they upload, so it's kind of invisible and worthless to sites like Facebook or third party services that access it, but that select users who the person who posted it want to see it have access to see it.
Mohli bychom se také zaměřit na šifrování nahrávaných dat. Facebook či na něj navázaní poskytovalé služeb by tudíž data neviděli a nemohli je použít. Data by se zobrazovala jen uživatelům, kterým to povolil ten, kdo data nahrál.
