How to keep people from reading

[ArMaP]

I believe TIFFs are actually technically compressed. I know its the same codec fax machines use. Bit failures though just result in random missing lines instead of total failure to display an image.

No, the official version 6.0 TIFF uses 6 different types of compression (besides "none"):
CCITT Group 3
CCITT T.4
CCITT T.6
LZW
JPEG
PackBits (a kind of RLE compression)
