Iris & Retina Multi-Modal System

The biometric capabilities of the iris are well known and the technology is widely adopted, representing approximately 10% of all biometrics today. Users of iris biometric technology, however, are well aware of the inherent problems associated with obtaining accurate and complete data. For instance, the iris is often occluded by eyelids and eye lashes. In addition, data collection can also be hindered by specular reflections in uncontrolled lighting situations. By using the complete eye biometric, the Retica system reduces the amount of iris data required to produce highly accurate results.

Answering the Needs of Security
With the recent heightened concerns for data, corporate and homeland security, the market demand has intensified for improved, biometric capabilities, and multi-modal systems. The Retica Multi-Modal System (patent pending) fulfills this need by combining the best biometrics of retina and iris into one solution.

The Best Combination
Built on new and unique algorithms, the Retica iris and data sets are easily fused facilitating accurate matching and fast database searching. The experienced Retica team of engineers, mathematicians and software developers has built a data analysis and management system which exceeds the capabilities of what is available in the market.

Efficient Design
The unique relationship of the retinal patterns to the iris patterns is exploited in the Retica Multi-Modal System. The retinal pattern and the iris pattern are simultaneously collected enabling the correlation between the iris and the retinal patterns to be embodied in the digital signal. Because of the tightly coupled, spatial relation between the retinal and the iris patterns, the combined pattern has significantly more degrees of freedom. This feature thereby reduces the amount of iris data required to obtain an accurate result since this data can be cross correlated with the retinal data. This relaxation of the requirement to collect a large amount of iris data will dramatically increase the user’s ability to collect sufficient data in uncontrolled environments.
