数码照相机在刑事照相中的应用

数码照相机已经进入人类生活,它具有普通照相机无法比拟的优势和特点。将数码照相机应用到刑侦工作中,可以提高工作效率,节省开支。文章介绍了数码照相机的特点、使用方法及其在刑事照相中的应用。     

谈数码相机的常见缺陷

在数码相机生成的数字影像上,会出现一些传统照片中没见过的色彩伪像、光溢、"毛刺"与"勾边"、色差、数码镜头景深的变化、宽容度等质量缺陷,在使用时应该特别注意,尽量避免。     

IoT forensics: Exploiting log records from the DAHUA technology CCTV systems

CCTV surveillance systems are ubiquitous IoT appliances. Their forensic examination has proven critical for investigating crimes. DAHUA Technology is a well-known manufacturer of such products. Despite its global market share, research regarding digital forensics of DAHUA Technology CCTV systems is scarce and currently limited to extracting their video footage, overlooking the potential presence of valuable artifacts within their log records. These pieces of evidence remain unexploited by major commercial forensic software, yet they can hide vital information for an investigation. For instance, these log records document user actions, such as formatting the CCTV system's hard drive or disabling camera recording. This information can assist in attributing nefarious actions to specific users and hence can be invaluable for understanding the sequence of events related to incidents. Therefore, in this paper, several DAHUA Technology CCTV systems are thoroughly analyzed for these unexplored pieces of evidence, and their forensic value is presented.     

书证提出命令制度的泛化适用与价值平衡——兼评新《民事证据规定》第47条

新《民事证据规定》第47条细化书证提出命令制度的适用范围,以期达到书证提出命令发现案件真实和追求实质平等的制度宗旨。但是限制性规定的缺位,以及明确将涉及国家秘密、商业秘密或者个人隐私等特定内容之书证纳入制度的调整视域,直接造成书证提出命令制度的泛化适用,侵犯公民和法律特别珍视的特定利益,引发非理性的利益冲突与价值失衡。基于此,理当在坚持书证提出命令一般性适用之前提下,规定必要的除外事由,适当限缩其适用范围,并以严格限制下的秘密审查程序为补充,查明除外事由的存在,以更妥善的制度安排寻求发现真实与特定利益冲突之间的价值平衡。
