Hi S Kumar Dubey,
From your description, I see you want to prevent some people from accessing the subscription report by prompt the
user for password. I am afraid there is no build-in feature to fulfill it.
However, as we know, Reporting Services has a unique extensibility architecture, which enables us to extend specific
features of the product and its components.
One possible workaround is that you can create assemblies to implement a delivering extension.
More information about how to Implementing a Delivery Extension, please refer:

Thanks,
Lola
