linux - Securely hide OS independent a directory using java -


i have project master degree , need java app load file (read attributes , copy file working directory), file, , make working directory private. private mean hide in way directory os (well, bascially windows , linux). i'm not sure os (windows , linux) functions hide directories work because admin/superuser can modify settings , access files.

the idea project have exclusive access loaded files within app , make them available aplications installed locally open/run them (like "open in media player"), should work when copy app usb stick. have 2 options: 1) modify each file after loading make unreadable world , undo modifications each time press "open" within app; 2) (which think best , simple option) modify root directory of files (root = working directory or subdirectory of it) unreadable/unaccessible world while outside app , readable app @ runtime.

i've been thinking making locally encripted copy of filesystem attributes of directory, "delete" them while not @ app runtime , put them while @ app runtime. didn't played before , windows&linux filesystems aren't simple @ all. more of it, usb stick have fat filesystem (which if i'm not wrong "belongs" dos), is, yeah, filesystem equation.

i'm sure not feasible (and not secure!) play , forth filesystem pleasure, need ideas find breakthrough without breaking anything.

thanks!

edit: i've found this in se8 docs while searching helpfull in java library. i'm not interested of reinventing "the wheel" of filesystems, make little tricks mine, might provide need.
