Security Considerations
PlanetPress Capture introduces new and efficient methods for digitally capturing the contents of ink laded
out on physical paper. However, because of its nature, some end users may voice concerns about security
and privacy. Are signatures secure? Could their transmission be intercepted? How can the contents of the
Anoto digital pen be protected from malicious users?
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 Workflow 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 Workflow (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.
