针对进程用户空间的电子数据取证方法研究

进程用户空间中的信息往往与特定用户的特定操作行为直接关联,对于证据链的建立意义重大.从数目繁多的用户空间数据结构中筛选出最重要的三种：进程环境块、线程环境块与虚拟地址描述符,说明其定位方法,并重点讨论其结构格式的电子数据取证特性,为内存空间电子数据取证提供了新的思路与方法.实例分析部分,则以目前广泛使用的Windows 7操作系统为应用背景,说明了所述方法的具体应用.     

资产占有的性别不平等与贫困

由于资产的获得与分配在中国一直是以家庭为单元而表现的,这在很大程度上掩盖了不同性别在获得资产的具体方面的性别不平等状态。家庭内部资产占有的性别差异在家庭内部隐含了不平等的要素。同时,资产占有上的性别不平等与农户贫困产生了交互影响。     

试析我国公司MBO中所存在的法律问题与对策——由张裕集团股权转让事件引发的思考

管理层收购在我国还处于起步阶段,国内目前尚无专门规范管理层收购的法律,完全意义上的管理层收购的合法性还不能确定.我国管理层收购大量涉及国有资产,其实质是对国有资产的一种处置手段和对经营者持股的一种深化.目前,在这种收购方式缺乏应有法律规范的情况下,如何有效规制管理层收购行为,保护国有资产,无疑值得深思.作者对我国MBO收购方式中存在问题根源的一些思考,并从法律角度对完善我国管理层收购初步探讨.     

GrinLine Identification Using Digital Imaging and Adobe Photoshop*

Abstract: The purpose of this study was to outline a method by which an antemortem photograph of a victim can be critically compared with a postmortem photograph in an effort to facilitate the identification process. Ten subjects, between 27 and 55 years old provided historical pictures of themselves exhibiting a broad smile showing anterior teeth to some extent (a grin). These photos were termed “antemortem” for the purpose of the study. A digital camera was used to take a current photo of each subject’s grin. These photos represented the “postmortem” images. A single subject’s “postmortem” photo set was randomly selected to be the “unknown victim.” These combined data of the unknown and the 10 antemortem subjects were digitally stored and, using Adobe Photoshop software, the images were sized and oriented for comparative analysis. The goal was to devise a technique that could facilitate the accurate determination of which “antemortem” subject was the “unknown.” The generation of antemortem digital overlays of the teeth visible in a grin and the comparison of those overlays to the images of the postmortem dentition is the foundation of the technique. The comparisons made using the GrinLine Identification Technique may assist medical examiners and coroners in making identifications or exclusions.     

数码照相在物证鉴定中的应用初探

数码显微照相、数码红外线反射照相、数码荧光照相、数码彩色分光照相、数码影像的处理技术在文书鉴定、痕迹物证鉴定中均可得到有效应用。随着数码照相研究的不断深入,数码照相在司法鉴定中的应用会越来越广泛。     

商业银行资产负债期限结构错配的流动性风险和利率风险分析

本文结合目前我国商业银行普遍存在的资产负债期限结构错配的现状,分析了产生流动性风险和利率风险的可能性,并认为利率风险是因流动性风险而派生出的风险。在此基础上,提出了商业银行流动性管理的三种方法:期限匹配法、资产组合法和综合法。     

双层社会视阈下数据犯罪的法益规制思路

从网络到现实,双层社会迅速形成,相关犯罪亦从现实社会迁移至网络社会。如何应对伴生的新型犯罪形态,关键在于能否全面、清晰认知双层社会的链接点——数据。数据犯罪随双层社会固化而持续扩张,立法、司法均提出各自的应对思路,但规制现状并不乐观。以数据犯罪为核心,分析该犯罪形态在立法与司法领域的表征,并结合其技术与社会的双重价值属性,针对受损法益展开分析,最终实现对相关罪名适用的逻辑化探索。     

A New Anti‐forensic Scheme—Hiding the Single JPEG Compression Trace for Digital Image

To prevent image forgeries, a number of forensic techniques for digital image have been developed that can detect an image's origin, trace its processing history, and can also locate the position of tampering. Especially, the statistical footprint left by JPEG compression operation can be a valuable source of information for the forensic analyst, and some image forensic algorithm have been raised based on the image statistics in the DCT domain. Recently, it has been shown that footprints can be removed by adding a suitable anti‐forensic dithering signal to the image in the DCT domain, this results in invalid for some image forensic algorithms. In this paper, a novel anti‐forensic algorithm is proposed, which is capable of concealing the quantization artifacts that left in the single JPEG compressed image. In the scheme, a chaos‐based dither is added to an image's DCT coefficients to remove such artifacts. Effectiveness of both the scheme and the loss of image quality are evaluated through the experiments. The simulation results show that the proposed anti‐forensic scheme can verify the reliability of the JPEG forensic tools.     

电子商务立法刍议

我国的电子商务立法 ,可先采用条例形式 ,在今后实践中再充实完善。电子商务法应设置总则 ;未满十周岁的儿童不能成为电子商务的主体 ,所产生的法律后果由监护人承担 ;认证机构应具有电子商务的主体资格。对签署、证据、成立等行为应作出效力规定 ;各级工商行政管理局是电子商务的行政管理机关 ,各级邮电管理局也应成为管理机关。当事人在交易中违反民事法律 (规 )、合同约定的 ,均应承担民事责任。
