Also in MySQL, if a timeout occurs on simultaneous record access, resubmitting the PGC
for processing should resolve the issue.

In SQL Server, if one of your requests is dropped because of simultaneous accesses,
resubmitting the PGC should resolve the issue.
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
