User specific data access

Hello, I am having trouble configuring user specific data access. I am all set with user roles I believe but on a specific user basis, John shouldn’t be able to see Marie’s data when logged into his account on a event page for example. I hope this makes sense and please let me know if you could guide me in the right path. Thank you.

Associate the data-entity to System.User and on the data-entities access rule add an Xpath constraint to:

[data-entity/data-entity_User = '[%CurrentUser%]']
