Details

contfiltd is a content filtering proxy for Parental-Control.

It performs:

  • filtering by bpjm.data
  • filtering by configured URL whitelists / blacklists.

BJPM (Bundesprüfstelle für jugendgefährdende Medien) is a german government agency which cares of media
which could be harmful to young persons. They maintain a blacklist which can be used to filter content.

An old version of this list is built into FRITZ!OS in bpjm.data, which is updated periodically by libuser.so.
