File blocking based on a hash value

[phodge]

hi all,

 

Hoping you can help me, I’ve done a lot of searching and not found anything.

 

I would really like to be able to block students from accessing files that match certain hash values while in school - no matter where the file is stored (email attachment, USB Pen etc.) (and using hash values rather than file names so they can’t just rename the file)

 

Sadly, these aren’t executable files so the software restriction policies won’t apply.

 

I'd also like to be able to update the list of blocked files over the network.

 

Does anyone know of anything that would let me do this?

 

thanks

 

Peter

if they arent executables then what type of extension do they have?
