Iris imaging in visible spectrum using white LED Abstract: Iris recognition in the visible spectrum has many challenging aspects. The B12 database is housed by a third-party vendor in an undisclosed location in San Antonio, Texas, and in three other disaster backup facilities. Perhaps the biggest threat of iris scanning is the danger of a national database that can track people covertly, at a distance or in motion, without their knowledge or consent. This raises significant civil liberties and privacy concerns which increase as iris data are collected from more and more people.

It may be possible for law enforcement officers to use long-range iris scanners on people simply glancing in their rear view mirror after being pulled over. There also are grave concerns with local law enforcement sharing biometric data to help federal immigration agencies such as the U. No biometric is foolproof. A research study showed that patients with acute iris inflammation also known as iritis or anterior uveitis caused current iris recognition systems to fail.

Quality problems were due to poor subject presentation e. The miss rates or false negative error rates for single irises ranged from 2. It is also possible to trick or bypass iris scanners. In , security researchers at the Universidad Autonoma de Madrid were able to recreate images of irises from digital codes stored in security databases. And then there is the issue of data security. Databases of iris biometric are a honeypot of sensitive, highly personal data that will be targeted by criminals.

Data breaches and hacks are at an all-time high. Making the risk of data breach even greater, law enforcement often stores its iris biometrics on databases operated by vendors and other private third parties. This also gives companies access to and control over criminal justice data, which many of their employees can access remotely.

As face recognition technology evolves at a dizzying speed, new uses and terminologies seem to develop daily. On this page, we attempt to define and disambiguate some of the most commonly used terms. For more information on government use of face recognition and how to end it in your At a virtual hearing Clearview AI extracts faceprints from billions of people, without their consent, and uses these faceprints to help police identify suspects. This does grave harm to privacy, free speech, information security, and racial justice.

Marking a big win for the privacy and civil liberties of immigrant communities, the Biden Administration recently rescinded a Trump-era proposed rule that would have massively expanded the collection of biometrics from people applying for an immigration benefit.

For unconstrained scenarios of iris recognition systems. In this thesis the merits of fusing information from various sources for improving the state of the art accuracies of colour iris recognition systems is evaluated. An investigation of how fundamentally different fusion strategies can increase the degree of choice available in achieving certain performance criteria is conducted.

Initially, simple fusion mechanisms are employed to increase the accuracy of an iris recognition system and then more complex fusion architectures are elaborated to further enhance the biometric system's accuracy. In particular, the design process of the iris recognition system with reduced constraints is carried out using three different fusion approaches: multi-algorithmic, texture and colour fusion and multiple classifier systems. In the first approach, one novel iris feature extraction methodology is proposed and a multi-algorithmic iris recognition system using score fusion, composed.
