l The PlanetPress Capture database, since it can be external to PReS Workflow such as
on a MySQL server, will be dependent on your own database security.
l The Anoto Digital Pens, since they may contain critical information, are just like physical
sheets of signed paper and must be kept secured. This is best done through training
employees handling the pens to be aware of its value and contents and act accordingly.
This means that the security of the pen is just as important as the security of any existing
physical documents you may handle at the moment.
l The same rules apply to PDF files as with PGC files, especially when they contain a
signature from the pen. If you are already securing digital scanned copies of signed
documents, the PDFs should be secured in similar ways.
However, remember that as with most security concerns, in order to be a “threat”, someone
would have to have a high level or working knowledge of either the Anoto SDK (which is not
easily obtainable) or PReS Workflow and PlanetPress Capture. In some situations this may be
enough (security through obscurity) but we always recommend having the same level of
security for Capture files and documents as you would the rest of your sensitive information. In
most cases, the procedures in place are enough for this purpose.
20,000 Patterns
When reading or learning about PlanetPress Capture, you may have seen a number pop up
here and there: "20,000 Patterns". In order to better understand what this number means and
what it entails for you, the user, this document will first present an overview of a typical
PlanetPress Capture implementation and then explain how the 20,000 patterns limitation can
be circumvented in some cases. We will also touch upon the potential pitfalls of these
workarounds as they are used.
The Numbers
First and foremost, the 20,000 patterns is a fixed number - PReS can only generate 20,000
unique patterns as this is the number of patterns that we license through Anoto.
The 20,000 patterns are, however, not all available when generating documents. There are 8
"demo" patterns that are used to generate documents when PlanetPress Capture is in demo
mode (no license activated), and react the same way that the bulk of the 20,000 patterns.
Another single pattern is used to register pens in the database, and one last single pattern is
used when printing a "Preview" from PlanetPress Design. So in reality, the number of available
patterns for document generation is 19990, but for simplicity's sake this FAQ uses the round
number "20,000".
