Temperature data logger

Detector Device

The device includes the following components:

• Microprocessor

• Bluetooth-module

• Temperature sensor

• USB-module (for supply)

• Flash drive

• Battery (will be added soon).

After activation, the detector starts automatic data collection and writes the received data to the built-in flash drive.

The detector sends the received data to the mobile app via Bluetooth. Then the app automatically writes down it to the blockchain.

Data protection systems (all below will be added soon)

The data is protected by the electronic signature, which using the Sha256 encryption algorithm. With that protect the data goes to the app. This feature allows to protect the data from forgery and pinpoint the sender.

• The data is encrypted by the RSA algorithm, which allows to protect the data from dubbing and downloading directly from the flash drive by opening the detector device.

• Protection against copying is realized by setting fuse-bits.

Thus, the device puts down the data into the blockchain, signs a transaction and gives it to the app.
