The Ubirch solution secures sensor data directly at the source, on the M2M simcard and not after it is stored in a Blockchain cloud.
Ubirch has a “trusted” protocol, which guarantees that the data from the sensors cannot be falsified after their origin. The data packets from sensors are sealed and provided with very strong encryption, in a way that makes it technically impossible to manipulate the sensor data once stored by means of Blockchain.
