Before addressing these concerns, it must be pointed out that these security issues are not introduced by this new technology.
In fact, they are essentially the same concerns that arise with plain pen and paper: if the signed document can be scanned,
then any markings on the page can be extracted and reused by anyone with even limited technical skills. In addition, the
signed document has, by definition, a longer life span than the temporary storage location of the digital pen. Consequently, it is
still the most vulnerable piece of the workflow and as such, it should be the first objective of any security effort.
In other words, as long as the physical piece of paper bearing markings is accessible to malicious users, no amount of security
protocols can protect the signed contents. It is only after the paper trail has been secured that the security and privacy issues
specific to PlanetPress Capture should be addressed.
Because PlanetPress Capture relies on external data and communication and because it may be used to process sensitive and
legal information, it is important to understand the security implications of any PlanetPress Capture implementation. Most of
the security concerns regarding Capture are external to it. This means the security that is implemented both on your network
and physical premises are critical to the security of your PlanetPress implementation.
Here are a few notable points with the security of PlanetPress Capture on a network:
l PGC Files, while not written in plain text, are not encrypted and are readable through either PlanetPress Production
(even a server that did not generate the document associated with it), or through third-party applications using the
Anoto SDK. This means if someone gains access to your PGC storage folder, they may be able to read the signatures,
checkmarks and other information contained in it and reproduce them on a document of their choice. It is always better
to secure this folder properly. You could also use third-party encryption software to secure the files, and decrypt them
as necessary for reprocessing.
l The transfer between the Anoto penDirector and PlanetPress Production is not encrypted due to a limitation of pen-
Director which does not support SSL connections. This means someone located anywhere between penDirector and
PlanetPress Production could use software such as a packet sniffer to retrieve its parts and recreate the PGC files. This
may be resolvable by create a secure VPN tunnel for each location where penDirector is installed instead of going
through regular remote HTTP server.
l The PlanetPress Capture database, since it can be external to PlanetPress such as on a MySQL server, will be depend-
ent 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 con-
tents 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 PlanetPress Production and PlanetPress Cap-
ture. 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.
Anoto penDirector
The Anoto penDirector is a software driver provided as a download by Objectif Lune Inc. The penDirector creates a bridge
between the Anoto Digital Pen and a PlanetPress Capture workflow in PlanetPress Production.
In order to use penDirector, it needs to be downloaded from the Objectif Lune website, on this page. This sofware must be
installed after PlanetPress Suite. The setup will install a pre-configured version of penDirector which can be immediately used
with PlanetPress Capture.
