[Typo3-dev] configure Access in Page header via a plugin on this page

[Andreas Förthner]

Hi list,

is it possible to configure/set the FE-Usergroup of a page in the page 
header via a Plugin on this page?
The problem is: I have a backend-module, that creates data in a database 
that is connected to a specific FE-Usergroup, which is also created by 
the module. The plugin now should read this data an automatically should 
show the page it is on, only to users of the connected usergroup.

How would you do that, so that the author, who inserts the plugin, 
doesn't have to know the name of the usergroup?

Thank you for your help.

Greetings Andreas
