Bosch software is distributed via the Bosch website, but can also be re-distributed by Bosch partners. It is important for the system-installer to check if the installation file he or she has received, matches exactly with the output of the engineering process. There are several risks that, in the distribution path, changes are made to the installation file. Keyloggers or other spyware could be added to the installation, or in theory video surveillance footage could be routed to external resources.
The attached document describes how the integrity of software can be checked.
