Scientists created a tool that makes the Internet of Things (IoT) safer and more protected against attacks and data leaks — especially in realities with limited computing and little storage.
The system’s difference is to protect without modifying the information, saving a watermark separately, which increases the security of messages between devices connected to the network.
Zircon (Zero-watermarkIng-based data prOvenanCe for IoT Networks, in Portuguese) was presented by the group of scientists who created it in a publication on .
“We have developed a zero-watermark system approach, which does not modify the original data, but can incorporate information about its origin, ensuring tamper-proof transmission across the network,” said Omair Faraj, lead author of the study and Ph.D. Networks and Information Technologies program at UOC and Télécom SudParis at IP Paris.
This solution is productive because the devices used in this type of integration using the internet — which are generally many and have limited processing power, short battery life and less bandwidth — cannot support large systems.
With Zircon, this information can be processed without requiring complex security techniques and difficult encryption.
“Our results indicate that Zircon is superior to traditional methods, especially for its lightweight processing, efficient use of bandwidth and reduced power consumption,” said Faraj.
What is the Internet of Things?
is a technology that allows everyday devices to be connected to the Internet and computers, enabling control, communication and interaction between them.
With this, it is possible to transmit data from the cloud with the integration of monitoring devices with the internet.
It works from a device that has a connection to a network, such as Wi-Fi or Bluetooth. Thus, it is possible to access various information that is stored in the cloud.
