The Door Lock Of The Future (Today): Using Digital Biometrics For Access Control
Access control to residential and commercial buildings is a major concern of developers and owners. Key based systems are subject to lost or damaged keys, poor key control, and physical deterioration. Numeric keypad or electronic locks triggered by proximity devices are more secure but still do not provide specific individual identification. Unauthorized, or intentionally malicious, disclosure of PIN numbers, cloning of electronic keys, or other vulnerabilities reduce the security benefit.
Enter the world of digital biometrics. Digital biometric combines the reliability of programmable access with specific individual characteristics that are not subject to copying or duplication. In other words, the ‘key’ to access the system is particular to an individual and not subject to normal copying or duplication.
Once such technology is Iris biometrics. The human iris is unique to each individual much like fingerprints. By using a digitally generated scan of the iris, a biometric based lock can insure access to individuals whose iris scan is contained within the authorized person database.
Are there vulnerabilities to an Iris based digital biometrics system for access controls? The short answer is no. While a number of security experts have proposed techniques for ‘spoofing’ or fooling an iris scanning biometric system, no one has been able to do so.
Some of the proposals involve a digital image of the iris adapted to a contact lens or other such similar method. Today’s iris scanners include protections to detect such attempts such as using a combination of iris scans and eye-movement. Thus, the security of these systems is extremely strong.
By contrast, fingerprint based biometrics have been easily fooled by synthetic skin duplication of fingerprints. The vulnerabilities of key based and other systems have already well documented.
Based on the vastly superior security of iris based digital biometrics, selecting such a system makes sense for all types of residential and business environments requiring secure and managed access.
Management of such systems for door locks and access control is a major consideration. The ease of inserting and managing authorized users is inherent within biometric control systems. Beginning with a simple digital scan of the Iris, personally identifying information entered, then selecting the level and location of access, the system cannot be simpler to implement. Terminating access is even simpler and reporting access times and locations fast and easy.
The benefits of secure door lock access control via digital biometrics are significant. Eliminating physical key control and non-specific individual identification systems vastly enhances security. Reduced management requirements also provides better use of resources.
Reduction in management overhead translates into more cost effective security solutions all while enhancing overall security of any location.
Adopting digital biometrics, such as Iris scans, to door locks for access control makes sense when one measures the effectiveness and security of these systems.
