Abstract: 智能卡作为一种存储数据的可移动媒质广泛应用于许多系统,例如电子商务和移动商务等。智能卡中的数据是通过用户的个人身份识别码(PIN)来保护的。但是,PIN作为一种口令存在着许多缺点,例如,它可能会被遗忘或者被盗窃,并且被破译。本文提出一种应用生物特征认证取代PIN认证的高可靠性的智能卡,以加强智能卡的安全性。整个数据处理过程和生物认证过程都是在智能卡中进行的,不会造成私密数据的泄漏。本文还设计了一套生物智能卡的应用系统模型。

Abstract: 生物特征数字证书涉及的RSA公私钥对可以由近似随机信号的生物特征密钥派生,但是生物特征密钥长度较短,而基于大素数分解困难的RSA算法要求密钥较长.为了解决该问题,提出一种生物证书密钥生成算法,结合对称加密算法和大素数生成算法生成生物大素数,并采用哈希算法对生物大素数进行可用性设计,在解决密钥长度问题的同时保证生物大素数安全可用,以便用于生成生物特征数字证书中的RSA公私钥对.基于VC6.0和MIRACL大数库的实验结果表明:基于生物特征密钥生成的生物大素数满足确定性和可用性,能够应用于生物数字证书之中.本文所提算法行之有效,且具有实际应用价值.
The RSA public and private keys of biometric certificate can be generated from biometric key which can be seen as random numbers.However, the size of biometric key is shorter than the RSA public and private keys. To overcome this limitation, a biometric certificate key generation algorithm is proposed. In this method, the biometric primes is generated by the combination of symmetric key encryption algorithm and prime generation algorithm, in addition, the hashing algorithm is used to ensure the feasibility of the biometric primes. The generated biometric primes are safe and usable so that they can be applied to generate the RSA public and private keys of biometric certificate. Experimental results using VC6.0 and MIRACL show that the proposed method not only is feasible, but also has practical application value.

Abstract: The biometric technologies for user authentication have been applied widely to identity authentication fields. But at present, the result of research on a biometric authentication system which is used for open networks has not been found. Identity authentication based on X.509 Public Key Infrastructure(PKI) and Privileges Management Infrastructure(PMI) are used widely and effectively in open network fields for authentication and privileges management. So on the basement of PKI and PMI technology, with the function of identity authentication and privileges management, the currency biometric identity authentication system based on Biometric Certificate is introduced. Finally, by designing a highly secure biometric smart card which can realize identity authentication and privileges management, proved the ability and operation of the currency biometric identity authentication system based on PKI and PMI technology.
论证据的种类

Abstract: 我国法律将证据分为八种是缺乏根据的。八种“证据”中只有物证、书证是两种独立的证据。证人证言、被害人陈述、犯罪嫌疑人、被告人供述和辩解只是人证的不同类型,而与物证、书证并列的只能是人证。勘验、检查笔录和鉴定结论都不是证据本身,它们只是反映了物证的物证资料。视听资料不是单一事物,其四种成分中只有一种成分是证据,且属于书证。根据以上分析,本文认为,证据只有三种:物证、书证、人证。证据都是由事实构成的,事实构成证据的情况只有三种:一是客观存在;二是被“书”记载;三是被人感知。三种情况下的事实只能构成三种证据。司法人员获得证据的途径也只有三种:一是找证物;二是找“证书”;三是找“证人”。

Abstract: 图像融合是提取各自信道图像中的有利信息,以综合形成高质量图像的一种专门技术。本文在对图像融合的基本技术原理进行简要分析基础上,结合Photoshop软件融合操作,将图像融合的技术应用与物证检验摄影有机结合,有效地解决了物证摄影的信息全面性和原始保留等问题,对痕迹物证的检验提取工作有较强的借鉴意义。
The image fusion is a technique which integrated to form high quality image by the extraction of useful in-formation in the image of each channel. Having briefly analyzed the basic principle of image fusion and combined with the operation of Photoshop in this paper, the author organically combined the technology application of image fusion and forensic photography, which effectively solved the problems about information comprehensiveness and the original reservation (and so on) in forensic photography. It has a strong referential significance for inspection and identification.
实物证据的鉴真问题

Abstract: 中国新颁行的刑事证据规定确立了实物证据的鉴真制度。根据所要鉴别的实物证据的不同,鉴真有两个相对独立的含义:一是证明法庭上出示、宣读的某一实物证据,与举证方“所声称的那份实物证据”是一致的;二是证明法庭上所出示、播放的实物证据的内容,如实记录了实物证据的本来面目,反映了实物证据的真实情况。中国刑事证据规定尽管确立了“保管链条的证明”方法,但强调通过对各种“笔录类证据”的形式审查,来验证实物证据在来源、收集、提取、制作、保管等各个环节上的可靠性。刑事证据规定还针对物证、书证、视听资料和电子证据分别确立了鉴真规则。鉴真制度要得到有效的实施,需要司法改革的决策者在刑事审判方式改革、侦诉关系改革、规范法官自由裁量权、有效实施排除规则等方面做出进一步的努力。
