Hi Hilmy,

I'm not sure if qgis, when using gdal is using gdal's proj definitions
or it's own.

But:
- for gdal's do a search for a file called epsg in your osgeo4w dir
(probably in proj dir).
- qgis get's it's parameters for a sqlite db called srs.db (somehwere in
 the qgis dirs in a dir called resources).

You can also define your own defintion in qgis and call it
'hilmysRight3168' and use that.
Or edit the srs.db with a tool like
https://addons.mozilla.org/en-us/firefox/addon/sqlite-manager/ for firefox.

A good source for all the different projection definition formats:
www.spatialreference.org

Hope this helps,
