Adding handwritten notes to secured PDFs
Can handwritten notes be added to secured PDFs using Javelin readers? The brief answer is No for desktop (PC and Mac versions) of Javelin – and Yes for the Android version – please see pages 16/17 of the Javelin for Android user guide. However, our view is that adding handwritten notes is really only practical when applied to printed pages, so if the page is printed out then it is simple of course and that would apply to any version if printing is permitted. On mobile devices the hardware itself (on Android and iOS devices) includes a facility to take a screenshot (this is hardware-based so cannot be prevented). This screenshot can then be printed and notes written on it. So there are solutions in this case, but in general an encrypted file cannot be directly modified, so any “solution” will have its limitations imposed by the device, screen size and the nature of secured files.
