[postgis-users] RE: Data security via Postgis

[Guido Lemoine]

Yong,

A WMS request to Mapserver "only" serves a painted composition of your
(feature and raster) data, i.e. not the actual feature or original 
raster data itself.

Your mapserver set-up controls what detail the user can get. Your user would
need to recompose your complete data sets, and re-digitise these to make use
of it as separate data layers. You could do some web request monitoring 
(e.g.
linked to your user's IP) to check his/her behavior.
