Blockchain technology can be used to include biometrics in systems. This way, biometric operations are secure because they cannot be tampered with or falsified. But there are limitations when it comes to biometrics. Let us look at the constraints and the potential applications of blockchain technology for biometrics.
Privacy-preserving biometric data
Biometric identification is a ubiquitous and popular feature of our everyday lives, and many smartphones now come with fingerprint sensors or facial recognition. While this technology has many benefits, it also has many privacy risks, impacting user acceptance and regulatory issues. Fortunately, there are a few ways to protect your biometric data.
Users must complete a registration process to make the biometric data secure. Blockchain technology and IPFS technology can help with this. Blockchain technology and IPFS can provide the safe storage and transmission of biometric data. The fingerprint biometric template can be derived from a random number generator to create a challenge. The bitcoin trading platform is a platform that allows people to gain more knowledge about the bitcoins and the cryptocurrency.
Costs of incorporating biometrics with blockchain technology
There are several costs to incorporating biometrics with blockchain technology. First, the storage of data is costly. For each 256-bit of data, 20k gas is needed to store it. This can be avoided by coding the biometric templates efficiently and using smart contracts.
Then, there is the problem of security. A biometric system needs to be secured from potential breaches. There are two types of attacks that could compromise its safety. These attacks would include: altering the biometric template in the database and intercepting the channel between the database and a matcher. The proposed solution would solve these issues. However, this approach is still far from providing optimal privacy protection. For this reason, it should be combined with an enhanced Biometric Template Protection scheme.
Moreover, biometric systems provide a range of benefits, including increased security, convenience, and fraud reduction. These technologies can be used in several industries, including banking and healthcare.
Limitations of blockchain technology for biometrics
While some biometric applications benefit from the security and privacy features offered by blockchain, there are some limitations to this new technology. For example, there is a need for highly secure biometric data encryption. Unlike traditional databases, which are publicly accessible, blockchains use a private process to validate transactions. While this can significantly improve security, biometrics is sensitive data that must be protected by the highest privacy standard.
Another challenge is the lack of computational power for biometric systems. A biometric system deployed in a private blockchain will only allow a small number of users, and complete user identification will be required. This approach may not be the best option for biometric applications. For this reason, an experimental procedure is being developed on public blockchain architectures.
Another limitation of blockchain technology is its cost. It costs several thousand dollars to store a million biometric templates on a blockchain, which is too expensive for most biometric systems. This cost can easily be avoided by ensuring the coding of biometric modules efficiently.
Potential applications of blockchain technology for biometrics
Blockchain technology can potentially improve significantly distributed digital identity schemes, including biometrics. The ability to store and share information in a distributed network would allow smart devices to perform actions and make decisions based on the data they hold. For example, a smart contract could manage the rental of a car. However, the current security level of biometric systems is far from adequate. A blockchain-based authentication protocol would be able to overcome this issue and improve security.
Currently, biometrics are used in many applications, including bank accounts, phone unlocking, and voice authentication. These technologies solve several common problems, such as the difficulty in managing many different access control cards. They can also be used in workplace settings to track employee hours and prevent fraud.
Blockchain technology offers the potential to include biometrics in applications. Biometrics can help make the workplace more secure and efficient. However, biometric applications are not without challenges. They can raise various compliance issues, including new laws and regulations. Our Global Privacy & Security Team can help you navigate these challenges and create biometric solutions compliant with the law.
