Very uninformed speculation. Visionect's previous products came with a water-tight, tamper-proof enclosure & a number of software based security measures, because one of their tablets interfaced with Point of Sale systems.
This is a bit more complex than a regular micro-controlled LCD. There are a number of ways you can drive an e-ink display. Then there are a number of ways you can choose to control such a display remotely. Last but not least, a sizeable chunk of the stack powering these displays is proprietary technology, and has been in development for more than 3 years.
Almost everything is hackable when you have physical access to the system. That's why such systems should detect and report tampering. Something regular traffic signs never did in the first place.
- groby_b 11y agoAnd why is "proprietary technology" a good thing? Limited visibility into the code really doesn't improve anything. Ask Chrysler about their Jeeps being hacked, how much that proprietary thing helped. And "more than three years". Oooh. OpenSSL was in development for what, 16 years, and heartbleed happened anyways. I have no doubt it's a little bit harder than a few weeks with a USB cable and a traffic sign, but assuming they will not be tampered with at some point is not born out by any facts we know about software.
