BioNANO Algorithm

Anviz biometric technologies are widely used in our fingerprint identification, face recognition and iris identification products. As one of our key technological achievements, the biometric identification algorithm——BioNANO, was domestically developed by our engineers and applied in all biometric products of Anviz.

BioNANO Fingerprint Algorithm

1. Suitable for dry, wet, worn fingerprints

2. Fast and consistent fingerprint matching

3. Fingerprint template automatically update

4. Automatically healing broken or damaged fingerprints

5. Intelligent auto updating of fingerprint templates to increase quality and accuracy

BioNANO Facial Algorithm

1. Used well in various environments

2. Fast and consistent facial matching

3. Accurate extraction of facial features

4. Match specific features to template

BioNANO Iris Algorithm

1. Live scan for highest security

2. Fast and consistent iris matching

3. Strong anti-interference capability

Photoelectronic Imaging Technology

Photoelectronic imaging technology is the key factor which decides the image quality in the image acquisition system. Anviz conducted in-depth research on the photoelectronic imaging technology and significant image optimization processing work on the mainstream photoelectric imaging chip technology in industry., and a lot image optimization processing work on the mainstream photoelectric imaging chip technology in industry. The technologies developed by this company include: Automatic Gain Control (AGC), Backlight Compensation (BLC), Electronic Shutter, Slow Shutter, High Signal-to-noise Ratio, Image Distortion Adjustment, Auto Exposure, Image Mosaic, etc.

Applied Optics

Anviz’s self-designed, ultra-depth, and monochromatic spectral optical lens meets the remote distance-imaging requirements of the face and iris recognition system. Anviz’s self-designed HD network camera optical lens, with ultra wide angle (horizontal viewing angle 80°) and low optical distortion (5%), provides the users with broader views and more details.

Radio Frequency Identification (RFID) Technology

RFID can be used in a variety of applications, such as: Access management, Tracking of goods, Tracking of persons and animals, Toll collection and contactless payment, Machine readable travel documents, Smartdust (for massively distributed sensor networks), Patient identification and electronic medical records,Airport baggage tracking logistics, etc.

Read/Write

We provide low-cost solutions for reading/writing 125 kHz (LF), 13.56MHz (HF) and 915MHz (UHF) RFID transponder tags. Anviz RFID readers are capable of supporting wide voltage input, managing antenna beam and anti-interference. They are designed in strict compliance with ISO10536, ISO14443, and ISO15693. These products are extensively compatible.

Multi-factor Authentication

Featuring multi-factor authentication, Anviz biometric smart card (13.56MHz) readers offer the highest level of security. Storing the fingerprint template only on the smart card, users benefit from the increased security, faster throughput, easier system management, lower costs for the biometric reader and reduced concerns over individual privacy.

RFID Middleware

We put our middleware into an "Edge Server Appliance" that can simultaneously process input from multiple RFID readers and interface to enterprise applications through wired and wireless networks.

Low-Power Design

Anviz biometric devices, RFID applications, and Video Surveillance systems are known of their low power capabilities. To ensure those hardware and management systems can properly work 24 hours a day, 7 days a week, we apply the latest low-power, energy-efficient technologies.

Communication Technologies

Multicast Technology:

IP Multicast is a bandwidth-conserving technology that reduces traffic by simultaneously delivering a single stream of information to potentially thousands of corporate recipients and homes.

QoS (Quality of Service)

QoS provides end-to-end service guarantees and policy-based control of an IP network's performance measures, such as resource allocation, switching, routing, packet scheduling, and packet drop mechanisms. It is required to converge voice, video, and data traffic to be carried on a single IP network. With IP QoS, we enable the networks to support existing and emerging multimedia service/application requirements.

CCA (Clear Channel Assessment)

CCA checks the signal energy on the channel before transmitting. In wireless networks, by detecting the presence of energy in the vicinity of the carrier, CCA can automatically adjust bandwidth mode to avoid channel interference. As a result, the wireless signal will be more stable. When the interference disappears, CCA can automatically bundle the free channel, making full use of the channel-bundling advantage and enhancing the wireless performance.
