Biometrics In Security
With the increased demand for security, systems are rapidly adopting biometrics to successfully ensure the identity of a user. It is efficient at preventing unauthorized access by other individuals as well malicious bots. Biometrics relies on measurement and identification of a physical trait of an individual like iris scan. However, incorporating biometrics with legacy systems can be challenging for many reasons listed Bahaa Abdul Hadi.
Challenges of Integrating Biometrics With Legacy Systems
Compatibility
The design of legacy systems is often incompatible with modern biometric technology, which makes integration difficult. The existing framework may not support the specific software or hardware components of the biometric technology. Significant modifications to legacy systems are needed to integrate biometric data, or middleware is used to translate data between the two systems.
Cost
Implementation of biometric systems is expensive. Integrating them with legacy systems comes with technical challenges which drive up the cost, especially if significant modifications are needed. Besides, subsequent testing and security audits are also costly. For organizations that operate on a tight budget such costs become prohibitive.
Security
Biometric authentication relies on collection and storage of sensitive personal data. This makes high quality security for storage and transmission of this data necessary to prevent unauthorized access. Legacy systems that do not have the necessary security protocols to protect biometric data, are vulnerable to cyberattacks and other security breaches.
Complexity
Integrating biometrics with legacy systems can be complex and time-consuming. The underlying architecture of the existing system is often altered significantly during the process. This makes extensive testing and subsequent auditing essential. These can lead to disruptions to business operations which can be detrimental for the company.
Training
Employees who are used to working with legacy systems cannot use the new biometric technology effectively without proper training. This makes adapting to the new system difficult as the employees resist change.
Accuracy
Biometric systems must be highly accurate to be useful. However, integrating biometric data with legacy systems leads to errors if the two systems do not communicate effectively with each other. This can also happen due to inaccuracies at the level of introduced middleware.
Scalability
Using biometric data for authentication needs a high volume of data processing. Legacy systems do not always have the capacity to meet this demand on processing capability. This increases processing times and makes the system slow and prone to crashing. This is a significant problem for systems which deal with high user traffic.
