摘要
为了保证安全性,生物确认系统往往提高判别阈值来获得低的认假率,但高的判别阈值会导致高的拒真率,所以确认系统在实际工作中有时会出现合法用户长时间得不到确认的情况。为了解决这个问题,文中提出了一种在一块DSP开发板上实现两个确认系统(指纹确认系统和声音确认系统)的方案,并给出了具体的软件和硬件实现方案。
The biometric verification system always sets a high judge threshold in order to get a low false acceptance probability. But the high judge threshold can lead to a high false rejection probability. So the legal user sometimes can not be verified for a period of time in practical work. The paper presents a method to develop two verification systems （finger- print verification system and voiceprint verification system） in the same DSP developing board. The theory of the verifica- tion system and the details of the software and hardware are also presented.
