as of now i am able to hide the data, but the data is hidden on both computers i.e both on remote and console machine. now i need data as it is in console and in remote it should be 'blurred' or 'starred' when simultaneously viewed.

You probably need to build your own viewer to achieve this

is it possible to customise the current ultravnc viewer?

This is not practical to implement. It would take an incredible amount of work to pull off as you would be modifying the VNC server code to support blurring, to support an interface so an application can tell it what sections of the screen to blur, and you would have to add code to your application to call this interface.

Not only that, this introduces a dependency to your application on the VNC server you modify. What if the VNC server isn't running? How do you handle that? What is you no longer use that VNC server and start using something else? Now you're screwed because your code will not work with another remote desktop library.

Good Luck! You're not really going to find any example code on how to do this. You're in uncharted territory. Nobody does this for any good reasons.

you are right, hardcoding the feature to a software wouldn't be the right approach.
Is there any other approach I could look into?

No.

There is no way to do this the way you want. An application cannot hide itself from the mirror render driver of a VLC server. If there is something you don't want the remote user to see, have them run a separate program that doesn't display it. You're not going to get a different display between the local monitor and the remote.

If I don't need the remote user to see it, I can hide the data in the same application instead of creating a seperate one. So trying to create a new VNC viewer is the only option left even if it brings dependency into the picture.
Thank you for the help though!

Good luck! You'll be the only person I've EVER heard of even attempting this.
