Description

Monitoring System and method using iris

The present invention relates to a surveillance system and method using the iris, and more particularly to a surveillance system and method that can manage the work attitude and security documents by analyzing the movement or pupil of the iris.

With the development of IT technology, the era of guards and access control personnel is out of bounds from outside, and they are performing guard and surveillance work in the situation room through CCTV and thermal equipment.

However, the situation monitoring using CCTV or thermal imaging equipment tends to be difficult to focus on, compared to the external boundary, so the boundary and surveillance tasks are often neglected. In particular, when it is necessary to identify hazards in advance and check for abnormalities through periodic monitoring, neglect of monitoring may result in preventable accidents.

On the other hand, in the management of reading of secret data, a manager usually monitors the viewer directly in order to view the secret data only within the permissible range and to prevent leakage of the read secret data.

However, in this case, since the entire monitoring process is to be monitored by the manager, waste of human resources is severe, and like the above-described situation monitoring using CCTV or thermal imaging equipment, the environment is difficult to concentrate, so the monitoring work is easily neglected.
