How Blockchain Technology Can Enhance The Security Of ID Cards?

26 Apr 2024

Blockchain technology has been widely known for its ability to store, secure and manage data. As a decentralised technology, blockchain is now used in many services. One of the significant use cases is its ability to provide secure and tamper-proof identification cards. In a world where identity theft is rampant, blockchain technology offers a unique solution to address the issue.

Limitations of ID Cards Without Blockchain

ID cards are physical or digital documents that contain personal information such as a person's name, date of birth, address, photograph, and other identifying details. These cards are used in various settings, including government institutions, schools, workplaces, and other organisations, to verify the identity of an individual. However, ID cards without blockchain technology have several limitations, including:

Vulnerability to Fraud and Forgery: Traditional ID cards are susceptible to fraud and forgery as they are physical documents that can be easily tampered with. It is not uncommon for criminals to create fake IDs using stolen personal information or forging documents, which can lead to identity theft and other illegal activities.

Centralised Storage: Most ID cards are stored in centralised databases, which are vulnerable to hacking and data breaches. If an attacker gains access to the database, they can steal the personal information of all the individuals in the system, leading to identity theft, fraud, and other illegal activities.

Limited Control Over Data: Individuals often have limited control over their personal information stored in ID card systems. The organisations that issue ID cards typically control the data, and users have limited control over how their data is used and shared.

Lack of Transparency: Traditional ID card systems lack transparency, which makes it difficult for individuals to verify the accuracy of their personal information. The lack of transparency also makes it challenging to track changes made to personal data, which can lead to errors and inaccuracies in the system.

Inefficient Verification: Traditional ID card systems often rely on manual verification processes that can be time-consuming and inefficient. This can lead to long wait times and delays, which can be frustrating for individuals who need to verify their identity quickly.

Traditional ID cards have several limitations that can lead to identity theft, fraud, and other illegal activities. The centralised storage and lack of transparency in these systems make them vulnerable to hacking and data breaches. Blockchain technology offers a solution to these limitations by providing a decentralised, secure, and transparent system for identity verification.

How the use of blockchain can address these limitations?

Here are some ways in which blockchain technology can address the limitations of traditional ID card systems:

Decentralised Storage: Unlike traditional ID card systems, where personal data is stored in a centralised database, blockchain-based ID card systems store personal data on a decentralised network of computers. This means that there is no single point of failure, and the data is less vulnerable to hacking and data breaches.

Tamper-proof: The data stored on the blockchain is tamper-proof. Once the data is recorded on the blockchain, it cannot be changed or deleted. This ensures that the personal data stored on the blockchain is secure and cannot be altered without the knowledge and consent of the individual.

Transparency: The use of blockchain technology enables transparency in ID card systems. All transactions are recorded on the blockchain, which makes it easy to track and verify the accuracy of personal information. This can help to prevent errors and inaccuracies in the system.

Efficient Verification: Blockchain-based ID card systems can use smart contracts to automate the verification process. This can reduce wait times and improve the efficiency of the system. Additionally, smart contracts can provide a higher level of security and accuracy compared to traditional verification methods.

Blockchain technology provides a decentralised, secure, and transparent system for storing, managing, and verifying personal information. By using blockchain technology, ID card systems can address the limitations of traditional ID card systems, including vulnerability to fraud and forgery, centralised storage, limited control over data, lack of transparency, and inefficient verification processes.
