Hiding and Recovering Data on Linux

Posted by CmdrTaco on Thursday March 14, 2002 @12:53AM from the hah-its-in-the-other-hand dept.

neuroticia writes "linuxsecurity.com has an interesting article on data hiding and recovery: "On a 4GB Linux partition, the block size is typically 4K (chosen automatically when the mke2fs utility is run to create a filesystem). Thus one can reliably hide up to 4KB of data per file if using a small file. The data will be invulnerable to disk usage, invisible from the filesystem, and, which is more exciting for some people, undetectable by file integrity checkers using file checksumming algorithms and MAC times. Ext2 floppy (with a block size of 1KB) allows hiding data as well, albeit in smaller chunks.""

You might want to hide pictures of the plants you are growing. Plants which you enjoy, and which ease the pain of people with MS or undergoing chemotherapy, but which are illegal. The fact that they are illegal may not bother you, but you could go to prison for it. So best to hide them away, then everyone is happy.

OK?
