Recent years have witnessed an exponential expansion of applications related to the Internet of Things, and it now plays a vital role in society. Internet of Things applications will make a tangible improvement to human life through different industrial domains such as smart homes and healthcare, farming, transportation, retail, wearable technologies, etc.
Security concerns have severely limited IoT adoption Internet of Things devices (IoTs) often fall prey to Distributed Denial-of-Service attacks due to numerous security flaws; DDoS attacks result in denial-of-service for targeted systems like central computers by flooding them with large volumes of requests at once from compromised computers, leading to disruptions for businesses and individuals alike.
Cybercriminals target IoT devices with lax security to mount DDoS assaults against these IoT devices that contain DDoS attacks against their targets; cybercriminals use IoTs with lax security to conduct these DDoS assaults against targeted systems to divide users' services.Current IoT networks also suffer from issues surrounding scalability. With increasing numbers of devices connected through IoT networks and existing authentication/authorization/linkage solutions becoming less scalable over time, any server failure would likely bring the network down ultimately and necessitate significant expenditure to purchase computers capable of transmitting information.
Blockchain, or distributed database technology (DLT), has emerged as an alternative solution to IoT scaling and security concerns. Blockchain stands out in terms of features and benefits in today's information age compared to any prior system; its fundamental feature is an Internet ledger shared between system users, which records events or transactions once verified, allowing an entire community of users to gather and share knowledge. In contrast, only new transactions that all members have approved are added.
How Can IoT Overcome Its Scalability Issues And Improve Security With Blockchain?
As cybercrime takes hold in IoT networks, identifying any data leakage may prove challenging; multiple devices may be managed and owned by different businesses transacting data transactions between themselves, with all parties involved often needing to be more transparent about who owns this information. Blockchain offers one way of mitigating IoT security challenges by providing improved transparency over ownership issues.
- The distributed ledger of a blockchain system is unchangeable, eliminating any need for trust between parties. IoT devices generate massive amounts of data, which are not controlled by any single entity.
- The Blockchain would provide additional security, making it harder for hackers to access the network. Blockchain offers a much higher level of encryption, virtually preventing pre-existing records' overwriting.
- A blockchain provides transparency by allowing anyone authorized to access the network to see a history of previous transactions. This is a reliable way to identify the source of data leaks and take immediate corrective actions.
- Blockchain can assist IoT organizations to cut costs by eliminating processing overhead associated with IoT gateways (such as conventional protocol costs, hardware costs or communication-related charges). Blockchain achieves this by enabling trust between stakeholders.
Smart contracts are two-party agreements recorded on a distributed ledger that record agreements between two or more parties that meet specific conditions to implement contractual arrangements between stakeholders. They may, for instance, automatically pay when particular criteria have been completed in terms of service delivery.
Possibilities Of Growth
Businesses should take four initiatives to strengthen the connections between their suppliers. However, they need to be patient because it takes time to implement these actions and see results.
Track And Enable The Internet Of Things Capability
Businesses must implement IoT functionality within their supply chains to track finished goods and individual components more effectively. IoT devices use sensors to gather information such as pressure settings, GPS settings, barcode scanning data, and temperature, then upload this to cloud-based servers via the Internet for upload.
IoT allows businesses to collect data in innovative ways from all points along their supply chains. These tools enable companies to keep tabs on everything from packaging food creation and distribution from component sourcing and manufacture through a retail sale and transportation of goods and monitoring operational conditions within production facilities and logistic facilities.
Notify Transactional Data
Organizations should leverage blockchains to store transactional data from IoT devices. Blockchain technology enables decentralized capture and verification of records to improve supply chains, ensure ethical sourcing practices, and facilitate more successful finances. The collected information may help streamline supply chains while strengthening compliance processes and providing helpful intelligence that improves supply chains overall. The Blockchain allows a system to be implemented, decentralized, and piecemeal, eliminating the need for extensive IT investments or costly third-party certification.
Align Data From Multiple Sources And Standardize It
Utilizing Internet of Things gadgets within a supply chain requires this kind of information extraction. Take, for example, a company that relies on inventory scanners to track stock entering fulfillment centers and temperature sensors recording storage temperature every hour - this organization would need to align tables to accurately record which items were kept at which temperature for how long.
Create Analytics Which Are Both Predictive And Prescriptive
Temperature data from fulfillment centers could be used to forecast when food will spoil accurately. A predictive model could then guide inventory planning and marketing decisions when selling food products that may soon go bad, further reducing food waste and increasing revenue streams. An agricultural firm, employed data collected through tomato production traceability to link cherry flavor with environmental conditions during growth and utilize predictive analytics to develop tomato varieties that would meet different consumer segments' requirements.
