The limitations and inconvenience involved in using alternative identification methods i.e. photographs, passwords and PIN codes have driven the growth of biometric technologies in last few years. Again, ever increasing terrorist attacks, plane hijackings and petty burglaries have underlined the need for biometric security measures around the world. On the flipside, some border control projects like e-passport, VIS, EURODAC, etc. along with some national identity scheme like Aadhar are playing the flag bearer for the biometrics industry in India. Amongst others, increasing security requirements for public security i.e. border control, national identity, internet & network access and financial transactions are acting as growth driver for the industry. The market has been lead by fingerprint technology for the last few decades. However, the vein recognition technology is gaining acceptance globally which is expected to grow rapidly in the years to come. For the time being, some known modes/ methods of biometric authentication are fingerprint, voice, retina, heartbeat and facial etc. Fingerprint biometrics, the least secure modality, is going mainstream with annual sensor shipments estimated at 1.4 billion units by 2020, up from 317 million in 2014. An emerging trend with respect to the EACS (Electronic Access Control Systems) market is the demand for integrated solutions that integrate immediate onsite response with electronic security and alarm systems. This growth is mainly attributed to heightened security concerns backed by government and regulatory mandates. EACS is being employed across various fields; ranging from defense to commercial sectors. With so much going around in the Biometric & EACS industry, one might ask ‘Where are all the vendors?’ or ‘Which vendors to trust for top notch Biometric solutions?’-as superior security is the foundation for the industry’s growth. So, here we are with a list of 20 Most Promising Biometric Solution Providers. Being closely scrutinized by a distinct panel of judges including CEOs, CIOs, CXO, analysts and CIOReview editorial board we believe that these companies will help mitigate the risk of security breaches and protect customer data to provide secure and convenient authentication processes via off the edge technological solutions and methods.
