Encrypting URL for WCF Service

When using WCF Data Services, more specifically in DevExtreme's WCF Odata service in c#, is there any way of encrypting the URL queries? I do not want the client to be able to see/modify the URL in order to get access to the data. I want to know if this level of obscurity is available, even if have authentication for the client and that the client only has rights to one ID.

For example: 

/AcountsByIntroducerID?entityID=1234

This URL exposes the ID and also allows a client to change the ID number. Would there be any way in WCF that would allow use to turn the above URL into a encrypted string?

Such as: /JDudfj8ddJFDJSLAFDLJuaeouru0

So this can be decrypted on the server side. Thanks!

I had a similar problem to solve. For solve it i used the following pattern I have encoded url parameters in one base 64 string.

Declare your WCF with one parameter

[ServiceContract]
public interface VCIWCFService
{
     [OperationContract]
     [WebGet(UriTemplate = "/{encodedParameters}")]
     string GetSomething();
}

In backend code you can decode encodedParameters with the following code

  string Url  = HttpUtility.UrlDecode(encodedParameters);
  Url = Convert.FromBase64String(Url );

and you can get a particular parameter with HttpUtility class :

Uri myUri = new Uri(string.format("http://www.nothing.com?{0}",Url));
string param1 = HttpUtility.ParseQueryString(myUri.Query).Get("param1");

I work with Objective-C Ipad app, and i encode the parameters with the inverse system
