Unique instance creator using templates C++

I am presenting an idea to create a unique instance of an object using templates.. This is very similar to Singleton design pattern..

The code may be look like this

class UniqueFactory

{

private :

   UniqueFactory()

   {

   }
public :

   static T * Instance()

   { 

        static T* ptr = new T();

        return ptr;

   }

};

So it will give the same instance of the object always.. For example

int *pInst = UniqueFactory<int>::Instance();

*pInst = 11;

pInst = UniqueFactory<int>::Instance();

*pInst , points to the same unique instance.

Another example is ( UserData can be any struct or class etc. )

UserData *pData = UniqueFactory<UserData>::Instance();
