l When configuring the ODBCconnection, your must use the Microsoft version of the driver, and
not the Native SQLversion of the driver. This is due to a technical limitation of the native driver
that interferes with the PlanetPress Suite database requests.
Specifically for PlanetPress Capture, these considerations mean the following:
l In Microsoft Access, the total size of stored document cannot be larger than 2GB and this database
will be very unstable in implementation with more than a few thousand pattern sequences being used
simultaneously. It is only suggested for small implementation with less than 10 pens, or for demos.
l In MySQL, the 16 megs packet size limit can be an issue if the PDFs created by Capture are larger
than this size; An error saying "MySQLServer has gone away" would appear in this case. This can be
fixed by configuring the max_allowed_packet setting in the MySQLConfiguration(Reference).
l Also in MySQL, if a timeout occurs on simultaneous record access, resubmitting the PGCfor
processing should resolve the issue.
l 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.
