Iris recognition is the general trend? Microsoft has applied for patent ... _iot

Recently, Microsoft has acquired a patent for iris recognition technology, which will be incorporated into Windows Hello for use in Microsoft's smartphone, notebook and other devices.

Iris recognition is one of the biological recognition techniques. Other biometric methods include human face, fingerprint, voice, retina, vein recognition, and because the human Iris has 266 feature points, far higher than other biometric technology of less than 60 feature points, it is considered to have higher accuracy and safety.

Iris recognition is an identification method which encodes and contrasts the iris features of human eyes by means of mathematical algorithms. According to the patent document, Microsoft's smart device can take multiple photos of the user's eyes from two or three directions. Eye photographs of each angle can detect iris features and create different data points.

In its patent application, Microsoft points out that the human eye is a partially transparent three-dimensional structure. When light passes through the pupil to the retina of the eye. By using light from different directions, you can obtain image data of many image frames, compare the data of at least two frames, find similar places, and obtain relevant data, which is consistent with the eye area of concern. The system then automatically determines the verification characteristics of the false eye based on the data, which is used to verify the real eye.

Because of its excellent security, iris recognition is currently widely used in industries such as security, online payment and finance, intelligent City, intelligent home, and smart mobile terminals. Domestic focus on iris recognition technology companies include Wuhan Rainbow Knowledge Technology Co., Ltd.

The company independently developed the iris Identification core algorithm and chip, providing iris collection, matching, database and iris high-speed ratio, such as series of hardware and software products. and provide custom solution services. The company has won more than 20 Chinese invention patents and more than 10 Chinese utility model patents.

In addition to chips and modules, Rainbow Technology has also developed a series of products, including Iris intelligent Lock, access control/attendance machine, login, registration machine and so on. The company also released the IRIS Identification Software Development Kit (SDK) for use by third party developers.
