Re: [jupyter] Re: Protected Jupyter Notebooks

2018-01-08 Thread Matthias Bussonnier 
For the preventing copy-past you can set some cell metadata to
`metadata.editable=false`, I think some frontend will then prevent you to
copy-past the source. It's pretty easy to get around though.

The notebook top-level metadata supports arbitrary fields. As notebook are
json you can easily add a random UUID to these. Once you have a unique UUID
per notebook, it's easier to setup a google alert that tell you whether
this UUID has been found.

Again it's relatively easy to remove, but you have to know it is there.

If you have a tiny bit more resources, then you can add a second field
which is related to the user having bought the book. Again, as notebook are
Json it's just a matter of opening the files, adding this field and writing
it back.
If you really have a lot of downloads, it can even be done really fast by
directly modifying the bytes in files. Simply set this field a first time
to a long, know string, lookup the bytes offset of this string, and now you
can do a quick raw search and replace.

And you can even be more sneaky, see for example this HN thread[1] with ZW
spaces, but you can also use Homoglyphs, to fingerprint leaks.

Preventing leaks will though I'm afraid be close to impossible.

Look at what other authors have done, like Jake van Der Plas, whose
notebook are open, but only part of the content that you get with the full
book.

Hi Matthias, anything at all that would discourage piracy and would make it
possible to track piracy would be great. We're open to all suggestions.

Re: [jupyter] Re: Protected Jupyter Notebooks

2018-01-07 Thread Matthias Bussonnier 
It also depends what you mean by "protecting content in Jupyter Notebooks"
does that mean making it hard to copy ? Does that mean figuring out a way
to finger-print the notebook in order to easily detect leaked version. Or
do you want a more complex tagging that would identify which user have
leaked the notebook ?

Completely protecting is hard, but there are potentially soft mitigation to
track notebooks if this is what you are looking for.
