  • The compact and cost-effective design is suitable for deployment in various high-security sectors, including banking, border security, and healthcare.
  • The patent reinforces Mantra's reputation as a global innovator in biometric technology.

Mantra Softech's Optical Fingerprint Scanner: A Leap in Biometric Security

The biometric security landscape is about to see a significant transformation with Mantra Softech's groundbreaking optical fingerprint scanner. Recently granted a U.S. patent by the United States Patent and Trademark Office (USPTO), this innovative technology represents a major leap forward in biometric security, particularly in liveness detection. By integrating optical coherent gating, it captures both the external and internal surface characteristics of a fingerprint, making it nearly impossible to spoof.

A New Era in Biometric Liveness Detection

Traditional fingerprint scanners have long been vulnerable to spoofing attacks, as they primarily focus on the surface patterns of the skin—ridges and valleys. These patterns, while unique, can be replicated using molds, silicone prints, or photographs. Mantra's new invention addresses this critical security gap by introducing a dual-path optical configuration. One path captures the conventional external fingerprint image, while the second path uses a broadband light source and a Michelson interferometer to capture the internal microstructure of the finger's subsurface.

Key Features of the System:

  • Dual Light Sources**: A conventional source for external imaging and a broadband source for internal imaging.
  • Zero Path Difference Michelson Interferometer**: Ensures precise coherent gating of internal fingerprint structures.
  • Two Optical Paths**:
  • First path captures surface ridges (external fingerprint).
  • Second path forms interference images of subsurface layers (internal fingerprint).
  • Two-Dimensional Photodiode Arrays**: Capture and process imaging data from both optical paths.
  • Compact Optical Design**: Lower complexity and computation overhead compared to multispectral or 3D optical imaging systems.

This dual-layer approach not only enhances security but also provides a seamless user experience. The system can detect and prevent a wide range of spoofing techniques without requiring complex multi-spectral analysis or large-scale data computation.

Applications Across High-Security Sectors

The potential applications of this technology are vast and span multiple high-security sectors:

  1. Banking and Finance: Secure ATM authentication, eKYC, and mobile banking login where biometric authentication is crucial.
  2. Border Security & Immigration: Enhanced passenger identity checks using non-spoofable biometric terminals.
  3. Defense and Law Enforcement: Accurate and secure access control for restricted zones and digital forensics.
  4. Government Welfare Programs: Preventing fraudulent benefit claims by ensuring genuine biometric identity during Aadhaar-based authentication.
  5. Healthcare: Patient identity verification at point-of-care with a focus on security and hygiene.
  6. Workforce Management: Liveness-verified biometric attendance systems for enterprises and industries.
  7. Consumer Electronics: Integration into mobile devices, laptops, or smartcards requiring secure biometric login.

By ensuring both internal and external surface imaging in a single scan, the solution provides a new standard of trust, speed, and reliability in biometric identity authentication.

Innovation Built in India, Recognized Globally

The recognition by the USPTO reinforces Mantra's reputation as a serious global innovator in the biometric field. The granting of this U.S. patent not only solidifies Mantra's technological credibility but also opens the door for international licensing, commercial partnerships, and product integrations in one of the world's most competitive markets.

"At Mantra Softech, we've always believed in solving real-world problems through indigenous innovation," said Hiren Bhandari, Founder, Mantra Softech. "This patent is not only a testament to the strength of our R&D but also to the relevance and impact of Made-in-India technologies on the global stage."

The Future of Biometric Security

With the U.S. patent now secured, Mantra Softech is poised to integrate this technology into its next generation of biometric scanners. The company is targeting deployments across critical infrastructure and public-facing systems. Additionally, Mantra is exploring international partnerships for technology licensing, OEM integration, and collaborative research projects to extend the reach of this invention.

Projections suggest a 30% increase in the adoption of high-assurance biometric systems in the next five years, driven by the growing need for secure identity verification in a digital world. Mantra's innovative approach is expected to play a significant role in this trend.

The Bottom Line

Mantra Softech's optical fingerprint scanner with dual-layer liveness detection is a game-changer in biometric security. By addressing the vulnerabilities of traditional fingerprint scanning systems, it sets a new standard for trust, reliability, and security in identity verification. As the technology continues to evolve, it is poised to redefine the way we approach biometric authentication across multiple sectors.
