I want to change this to follwoing

Create a custom service behavior (IServiceBehavior) - that hooks up a custom operation behavior (IOperationBehavior) that will inject the the extra parameter. It may be you also want to implement your own AuthorizationManager - but it's most likely that you can do with the features (OperationContext.Current.SecurityContext and System.Threading.Thread.CurrentPrincipal).
