I had a similar requirement sometime back and remember vaguely using something like below to serve the purpose :

protected override bool CheckAccessCore(OperationContext operationContext)
        {
            string actionName = GetActionName(operationContext);
            /* do what all further authorization check you want to do
             * like "can user access method with actionname="Create"*/
        }

        private static string GetActionName(OperationContext operationContext)
        {
            string action;

            if (operationContext.RequestContext != null)
            {
                action = operationContext.RequestContext.RequestMessage.Headers.Action;
            }
            else
            {
                action = operationContext.IncomingMessageHeaders.Action;
            }

            if (action == null)// REST Service - webHttpBinding
            {
                action = WebOperationContext.Current.IncomingRequest.UriTemplateMatch == null || WebOperationContext.Current.IncomingRequest.UriTemplateMatch.Data == null
                         ? String.Empty : WebOperationContext.Current.IncomingRequest.UriTemplateMatch.Data.ToString();
            }
            else
            {
                action = action.Split('/').Last();
            }
            return action;
        }

You can tweak above code snippet to better closely meet your requirement but for sure this will give you clear picture on how to extract method name.
