The Role of Blockchain in Securing IoT Applications

Blockchain can make IoT systems safer by spreading data across many places. This way, data is not kept in just one spot, making it harder for hackers to get it.

Blockchain stores data in blocks that are shared across several computers. If someone tries to change the data, it will be noticed right away. This helps keep information safe and reliable.

Blockchain also helps to check if devices are real. Each IoT device can have a special ID stored on the blockchain. This ID helps make sure the device is not fake or hacked, adding another layer of protection to the system.

IoT App Security: Why Data Privacy Is Critical

As more devices connect to the internet, it’s very important to protect the data they collect. These devices can store personal information, so we need to keep it safe from hackers.

Here’s how IoT apps keep your data safe:

• Data Encryption: Data is changed into a secret code so no one can read it unless they have the key.
  
• Secure Login: Apps use extra steps, like a password and a code, to make sure only the right people can use them.
  
• Regular Updates: Apps get updates to fix problems and keep the app safe.
  
• Safe Communication: IoT apps use safe ways to send and receive data to stop hackers.
  
• Access Control: Only trusted users or devices can see or use certain data.

These steps make sure that IoT apps keep your data safe and private.
