I want to add some security to clipboard manager. I have developed an application. Inside my application i am giving the option to copy and paste but i don't want the data copied inside my application to be available outside my application, but it is available in the history of clipboard. How do i solve this? I have tried to solve it by setting the copy to null onpause of my application that would eliminate the paste option but the contents are still available in the history of clipboard manager.

How do i remove the contents in Clipboard Manager ?

(or)

How do i control the text that goes into the clipboard manager so that i could encrypt the data ?
