How to tackle confidentiality of names of acceptors?

Following options are given:
* inform all actors that treatment partners/'reporters' will not see data from any other treatment partner
* guarantee confidentiality of data e.g. by contract between treatment partner and WEEE system / WF-RepTool access administrator, staff members and/or charged experts or auditors of the WEEE system / WF-RepTool access administrator will have to sign a confidentiality agreement
* in case (e.g. not for hazardous wastes) agree that a code for the name of the acceptor will be used and only any independent auditor will check the name of the acceptor (cross check e.g. with delivery documents, check e.g. technology given)
