Encrypted image backups open to new attack.

By John E. Dunn, Techworld

Bitmaps stored inside encrypted backup files could be vulnerable to a 
sophisticated ‘comparison' attack, a German security researcher has 
discovered.

The vulnerability will interest anyone storing image data in backup 
files, because it raises a small but theoretically significant level of 
doubt about their security under everyday circumstances. The technique 
could also have interesting implications for police investigations where 
officials suspect 'invisible' data to be encrypted inside already 
encrypted volumes.
