Binding MVC model with knockoutjs mapping plugin expose all the data in view source

In our project we used knockoutJS Mapping plugin to map the MVC model using the following 

var data = @Html.Raw(new System.Web.Script.Serialization.JavaScriptSerializer().Serialize(Model));

$(document).ready(function () {
 viewmodelCO = new ViewModelCO(data);
 ko.applyBindings(viewmodelCO, document.getElementById("divID"));
});

All things works perfectly OK, but my problem is the data security, when we use @Html.Raw is expose all the data and if someone right click on the page they can see the original Raw data .

How can we prevent this situation, I know one option is re-write the code and get the data using Ajax request but this is like another call to the server after the page load and that was the reason we start using the MVC model to Map the knockout object. Any suggestions ?

If you want the web page to manipulate the data, the data is going to have to be sent to the client. That can either be done how you're currently doing it, or, as you mentioned, via a second AJAX request. Either way, you're sending the data to the client (and doing it via AJAX isn't any more secure -- it's trivial to see the data coming over the wire).

If you're concerned about the data, make sure you're only sending what is necessary to perform the task and nothing extra. That may mean you have to reduce the data a bit, but it'll bring your more security.
