Hi Matthias,
Thank you for your response. For some background context, the notebooks
will have access to sensitive data sources that we don't want to have
leaving the notebooks, and we also don't want to have users can inserting
their own content into the environment.
Blocking copy and paste is one of the main features that we wish to
achieve. Essentially, we would like to ensure that a JupyterHub notebook
user is able to use and modify their notebooks at will normally (via
typing, clicking and normal keystrokes), but disallow them from inserting
or removing data to and from said notebooks via copy/paste. Additionally,
we would like to prevent the the mouse right click or equivalent keyboard
event as well.
In the meantime, I will go ahead and take a look at inserting the
Javascript example solution you have provided into the Jupyter Notebook
image and evaluate if it meets our requirements. I will also experiment
with additional Javascript code in that js file intercepting other events
(equivalent to right click) in addition to Clipboard event. If you have any
other ideas or suggestions, please let me know.
Thanks again,
Jeremy
