Securing files

[entliczek]

Can't you just create a new user and a special group for him and limit 
access privileges to that precise folder only to that user/group? That 
way only "the mysterious application" would be able to access them. It's 
perfect and very simple solution.

Storing especially video files (that are usually quite big) in a blob is 
not very efficient and would kill data base engine if someone would like 
to open big movie.

Need more info. Is it online/web/server application? What's its main 
purpose.
