Data security remains a key concern in the rapidly expanding field of the Internet of Things (IoT). While connected objects generate a continuous stream of data, much of this information contains sensitive personal data, such as location data, consumption habits, medical information and much more. Protecting this data is therefore becoming a major priority, to guarantee users' privacy and avoid any potentially damaging security breaches.

The decentralized architecture eliminates the need for a trusted third party to verify and validate data, making it an extremely reliable solution for the IoT. When a connected object generates data, it can be encrypted, signed and recorded on the register. This means that every time a data transaction takes place, it is recorded in a newly created block, making the data history clearly visible and traceable.

By using Blockchain for data transfer in the IoT, users can be confident that their personal information is protected by an advanced encryption layer and transparent verification. What's more, in the absence of a centralized point of control, the risks of hacking and unauthorized access are considerably reduced, as a potential attacker would have to compromise a majority of the network to alter the data.
