Dual Iris Recognition System that meets ISO 10794-6 standards for iris image quality

Category:

Overview

Overview

The industry’s first dual iris recognition system to employ face display based subject positioning for an intuitive, fast and effortless user experience. The EF-45 is an embedded terminal with all image processing, iris encoding and matching on-board. It is intended for a large range of identity assurance applications, especially for which subjects may not be acclimated. The EF-45 meets ISO 10794-6 standards for iris image quality, thereby providing outstanding matching accuracy that is suitable for large scale identification (1:N) applications. The system also automatically captures high quality face images for record association or optional on-board face recognition.
The EF-45 next generation dual iris imaging system provides unprecedented subject ease of use through a highly innovative and intuitive user positioning approach. Subjects will view their own face in a front-facing, high resolution 5.0 inchcolor display to position themselves correctly within the real-time graphic interface. They will intuitively and naturally move to the correct position by simply centering and sizing their face image to the box within the display. In addition, the positioning box and the top border turn green to indicate proper distance positioning, after which the iris biometrics images are automatically collected, provided that the real time image quality metrics are satisfied.
In addition, this system features an expansive capture range of 35 to 45 cm in enrolment mode. Now, capturing highest quality iris biometrics images is fast, simple and fully intuitive for all subjects, including non-acclimated ones. For small scale access control or time & attendance applications, the capture range can optionally be extended to 30 to 45 cm in recognition mode, further increasing positioning flexibility and ease of use.
The system also captures a high-quality face image simultaneously with iris image capture. On board face recognition is optional.WiFi and card reader options are also available.

Innovative, Intuitive Subject Positioning

Innovative, Intuitive Subject Positioning

The EF-45’s face imaging sensor detects and displays the subject’s face at up to 1.0 meter from the system on the high resolution color display. The subject will naturally move toward capture range of up to 45 cm by simply making his or her face fit the positioning “guide box”, which is the capture or focal range of the system. Vocalized instructions also command the user to move forward or back to get into range. When in the proper range, the guide box and top border turn green, indicating to the subject to stop and wait until the image capture process is completed. Like a smart phone “selfie” image, this interface is highly intuitive, with typical capture times of less than 1.0 second from proper positioning.

Key Features

Key Features

Feature User Advantages
State-of-the-art optical design The optical design includes utilizing highest quality optics and very fast shutter speeds, which allows the systems to exceed industry standards for image quality.
Advanced, proprietary stereoscopic eye localization The EF-45 accurately locates in real time the position of both eyes in 3D to optimize subject ease of positioning and iris image quality. This feature enables the fast and reliable subject distance positioning indicators shown as blue, green or red color codes.
Highest image quality Meets or exceed the ISO 19794-6 2011 and ISO/IEC 29794-6 iris imaging specifications.
Compact, lightweight design Optimizes placement or mounting options, including wall, swing-arm, or eGate mounting solutions.
Simplest of user instructions Very simple and repeatable subject instructions:

·         Position face within guide box in display (like smart phone “selfie”)

·         Move toward the system to size head to box.

·         Once within range, the box and indicator bar will turn green to indicate proper positioning.

Capture is automatic once subject is in proper position and real time image quality metrics parameters are met.

Stand-off distance of 35 to 45 cm in enrollment mode Standard extended range ensures robust, fast and easy positioning. Comfortable range for subjects in wide variety of desktop, countertop, kiosk or wall mount placements.
Optional Extended Depth of Capture for iris authentication in recognition mode Depth of capture can be extended to range of 30 to 45 cm in recognition mode (not necessarily ISO compatible). Intended for small to medium scale access control deployments. Selectable in SDK.
Real time image quality metrics Subject gaze angle (i.e. whether the subject is looking directly ahead at the imager)

• Subject motion

• Focus

• Usable iris area (occlusion)

Face image capture Face images are collected in synchronization with the biometric iris images, so that the data record consists of one face image and two iris image.

 

Note:

The face images do not qualify as ISO standard, and therefore are not intended for large scale face recognition purposes. They are intended for small scale face recognition and manual verification of the subject’s identity

Very wide interpupillary distance The wide interpupillary distance range accommodates all adults and young children, making it ideal for large scale, public authentication programs.
Large on-board data bases for on-board identification and authentication Standard on-board (local) iris data base of 10,000 subjects (iris template-pairs), with matching speed of about 1.0 second in 1:N mode.

 

Optional expanded data base size of 40,000 subjects, with matching speed of about 1.0 second in 1:N mode (with special processing acceleration functionality).

 

Face template data base size of 1,000 subjects.

Modular version for integration into kiosks or other enclosures Directed at OEM’s and system integrators, this is a modular configuration that can be integrated into a kiosks and similar configurations.

 

(Contact CMITech for product details, designs and drawings.)

Cable connectors Plug in connector kit for all cabling (except RJ-45 Ethernet) included in accessories package
WiFi option Field installable WiFi dongle for ease of networking installation. (Contact CMITech for WiFi dongle specification for each country.)
Card reader option Standard in EF-45 AC version only, this is an embedded MiFare card reader for support of dual or multi-factor authentication, or backup authentication for special case users.
Local language support Screen commands for both subject and integrator are available in multiple languages. Please contact CMITech for list of languages that are supported.

 

Positioning vocalizations can be modified into local languages by systems integrators through modification of on-board .wav files.
