W2L? Car Forensics - now

What if one encounters an aftermarket stereo head unit? The aftermarket is quite robust and popular in the United States, so one will not only encounter OEM stereo head units.

How to connect aftermarket Android 6.0 stereo head unit to the OBD2 system

By changing any multimedia units and replacing by aftermarket devices its important to know that the device has to be trained (tech coded) to the manufacturer's cloud. If the driver the next time visits the dealer the car-cloud rejects the device (did not know of the change).

Actually aftermarket devices will run smoothly - but be aware The more the cars get automated (prev autonomous) the more the manufacturer protect any unauthorized (dealer only, cert-based) access or changes due to liability of automated driving enhancements.

Two things Little refresher of CAN bus - second a LIDAR animation for better understanding.

CAN What do you remember? CANL, CANH, CAN FD, AID, IDE, DLC - try know by heart the abbs
Inside a CAN (bus) packet AID Arbitration ID (broadcast, lower AID wins at timely collisions), IDE IDentifier Extension (0 for standard CAN, Question What for CAN FD?), DLC Data Length Code (0-8 bytes, size of data), Data (data itself, can be up to 8 bytes, but some systems force padding out the packet (filling with zeros).

Second See a LIDAR Light Detection And Ranging animation here

Keep becoming a car forensics expert - feel weak, no prob - tomorrow you will be -)

Next step RADAR RAdio Detection And Ranging. See here from a Volvo a electromagnetic spectrum overview (zoom-in by your browser) and then the two scales old and new about the ISM Industrial Scientific and Medical band spectrum

RADAR and LIDAR are bros -)

Volvo's Pedestrian Detect Systems - visually, see here (the RADAR underneath is assisting)

In the car a AI-based central control unit works to sense, map and make policy.

Tesla's RADAR is almost invisible because demoted, try to recognize the next time you watch a Tesla - really hard to eye-catch

Train your eyes to become an expert -)

Lets continue MOST Media Oriented Systems Transport - the infotainment backbone. As forensics except from security issues in cars is searching for evidence like GPS or calling/messaging MOST is the piece to crack.

A short slideshare to start. More tomorrow -)

Transmitting audio, video and control data over fiber leads to security-assisting functions. Lets say a rear camera is in use for parking. Lets assume the cam saw but not recohnized a human. Which unit would you investigate to find evidence? Where is the data processed, stored or sent-out to the cloud? How is data divided for real-time processing and/or stored for AI-algo feeding?
There is good reason for storing and linking to date, location and weather conditions. The driver expects and pays for his car for ˋlearning and improvingˋ which should result in higher security.

The front cams are often in collab with radars. Think the radar detects and the cam analyzes. To feed the cloud-AI - BIGBRAIN - the video data needs high accuracy and also high compression codec-based in the data-container. A fast cloud-AI UpLoad UL over carrier-aggregated 5G (e.g. 16 CAs, min 4 antennas, 4x4 MIMO) will enable multi-car live-maps replacing aged RDS Road Data Systems. Out of cloud-AI BORS orgs can faster provide limited resources.

Missing Person searching could also get improved by large-scale mobile Car-to-Cloud-AI C2CA.

The more cams the more INTEL - and sadly more surveillance.

Back to work Where is video data stored in a car? HighDef brings TBs 😉

For the greatest poster on FF and a unique excellent best of class forensics professional

See the ACC front radar on the left low position

We tested a full day a new system of detecting and video evidencing Mobilying While Driving MWD.
The results are moderate and we recognized that connected cars RF-shadow others for best triangulation.

Who is also running any MWD system to enforce Driver Distraction Enforcement DDE?
