项目摘要

1. Pen-movement angle, acceleration and vector parameters were introduced and fused in other to improve the performance of DWT domain on-line signature verification. In addition, it was found that the variation of optimum threshold values had relation with the complexity of signatures. We proposed threshold equalizing methods based on the complexity of the signature. As a result, the verification rate of 99.0% was achieved.2. Voice verification using the pitch was proposed and its performance was examined. The verification rate was 74.3%. Additionally, the voice verification using the cepstrum was examined. The verification performance was improved to 88.5%. Also, the norm reduction method was proposed.3. Multi-modal biometric authentication fusing the on-line signature and the voice was examined. The verification rate of 97.5% was achieved using the weighted sum rule. Also, it was confirmed that adjusting the threshold value in each modal improved the verification rate.4. We tried to implement the multi-modal biometric authentication in the PDA system based on Windows Mobile OS and Visual Studio 2005.5. We tried to implement the multi-modal biometric authentication using the on-line signature and the voice in FPGA.In this time, the auto-correlation function in pitch detection was implemented in FPGA.

1.为了提高小波域在线签名验证的性能，引入了笔运动角度、加速度和矢量参数，并将其融合到其他参数中。此外，还发现最佳阈值的变化与签名的复杂度有关。提出了基于签名复杂度的门限均衡方法。结果，验证率达到99.0%.语音验证使用的音高提出了其性能进行了检查。核实率为74.3%。此外，使用倒频谱的语音验证进行了检查。验证性能提高到88.5%。提出了范数降阶方法.研究了融合在线签名和语音的多模态生物认证。使用加权和规则实现了97.5%的验证率。此外，还证实了在每个模态中调整阈值可以提高验证率.本文尝试在基于Windows移动的操作系统和Visual Studio 2005.5的PDA系统中实现多模态生物认证。本文尝试在FPGA中实现在线签名和语音的多模态生物认证，并在FPGA中实现了基音检测中的自相关函数。
