Iris Identification

<p>In view of the limitation of traditional identification, it is easy to lose and copy keys, cards or ID cards, and it is easy to forget the password. Here, an embedded application system was designed based on the iris identification technology, the functions of gathering, inputing, and registering the iris information and identification can be realized. The system architecture was designed by using the embedded microprocessor of advanced RISC machines (ARM), which is used as the core. The iris sensor was used to gather the iris information, and the development of software was accomplished with the embedded OS Windows CE. The system can be used on the company entrance guard system, customs security of airport and criminal identification.</p>

Use Case Model

Because of the multi-user and multi-function characteristics of the Teaching Management System of universities, the application system is usually designed to be distributed architecture. This paper analyzes its complex functional demands through building a use case model, finds out the key factors from the aspect of the use case model, and finally meets the distributed needs with the application of lightweight container architecture. The analysis and design of the distributed teaching management system can reduce the risk of failure, and the functional demands of the application system can be realized gradually with the coherence of the architecture.

Acquisition Method

Capturing an iris image rapidly is required for iris image acquisition embedded system. For the traditional method, an iris image must firstly pass through the quality evaluation, which is complex, so the acquisition speed is very slow. This paper described an iris acquisition embedded system, and a new capturing method. The system includes an DSP DM642, and some relevant peripherals. When an image is acquired, it is filtered by the capture-control function, if passed then be stored the image, until capturing the assigned amount. Using this method, we can rapidly capture the high quality iris images at about 0.8s, and 83% of the stored images can be used for the next procedure. At the same time, it is convenient for the user to capture.
