    How to secure QR codes with blockchain?

     

    QR codes are becoming popular throughout many applications aside from their real uses in the manufacturing arena. The extensive usage of camera smartphones with various apps which can read QR codes are saving people's time. The usefulness of secure QR codes has led to a great explosion and those are securing documents, marketing, easy to use etc. 

     

    The world of secure QR codes:

     

    Initially, the QR code was designed for a distinct purpose due to the open standard on its base, it's capacity to have the density of information /unit area. The expansive growth of smart mobiles is giving every person the capacity to get a QR reader on request. Over the last few years, the usage of QR codes has been growing extensively. 

     

    The main elements of the blockchain technology is a) Distributed ledger (each participant can watch the transactions, verify & keep a copy) b) immutability (Can't be altered or transformed illegally), decentralised ( without any governing authority), Great security (with the help of hashtags, cryptography and encryption).

     

    The secure QR codes can help the information to be secured while at the moment of generation by using an exceptional private key under the control of the issuer. It prevents any kind of illegal/unauthorised tampering. Many companies provide secure QR codes based on standard cryptography and consist of a great level of security. The code is the distributed ledger itself and what is required for the verification is the public key that can be distributed according to the transaction and requirement of the issuer.

     

    The secure QR codes are distinct from various regular URL based QR codes. The secure QR codes use easily available web-based tools for verification and apps on smartphones that can be accessed without hassle. It provides functionality and security. 

     

    Good security of QR codes through blockchain

     

    You can see the advantages of blockchain via blockchain-based QR codes, which will lead you to the safer corner. The general QR code stays at greater risk as the information and data can be tampered but in this scenario, it will not happen like this as blockchain secure QR code.

     

    Blockchain technology secure QR codes

     

    The secure QR codes based on blockchain are extremely safe to use. Many websites like banking websites are utilising secured QR codes based blockchain for 2-factor authentication. The customer needs to login into their respective accounts, then they receive a prompt for scanning the QR code. With the help of a mobile banking app, the additional layer of verification is obtained.

     

    The whole system of blockchain-based QR codes is immutable, incorrigible, self-expandable, self-patchable without any failure points. Once the hash value in QR codes is there, a single person can not touch it. This hashtag technology through blockchain is almost impossible to hack by hackers as it will need various PCs to tamper with information and it is impossible. So it is fully clear blockchain secure QR code and blockchain-based QR code is much safer than the normal ones.


    So we can understand the general QR codes are modifiable and are vulnerable. Blockchain secure QR codes and are tamper-proof. Use blockchain-based technology as no one can hack or modify them.
