I would very probably put a filter in my client processing or write a server extension that takes care of it before returning the data.
Alternatively you can look into a system like structr.org on top of Neo4j which has schema support and also data level security and handles such things automatically for you. Also note that your user level cypher queries are super unspecifc cross products across the whole graph and are likely to perform very badly.
