计算机取证技术研究

随着信息技术的发展,电子证据逐渐成为一种新的诉讼证据。作为计算机领域和法学领域的一门交叉学科,计算机取证正逐渐成为人们研究与关注的焦点,如计算机取证的概念、原则、步骤以及计算机取证的相关技术、计算机取证的发展方向等。     

Digital traces and physical activities: opportunities,challenges and pitfalls

The strong integration of consumer electronics in everyday life offers many new investigative opportunities. In particular, digital traces from smartphones, smartwatches and activity trackers can now increasingly be used to infer information about actions performed by their users in the physical world that might not be obtainable from any other types of forensic evidence.While potentially very valuable from an investigative perspective, making forensically justifiable statements about such traces can sometimes be more difficult than expected. Requirements for this have not yet received much attention in the digital forensic literature. To help filling this gap, we describe the principles we use in determining the evidential value of such traces, which emphasize the need for experimental verification. For such research, aimed at determining the evidential value of these traces, we coin the term data2activity.In this paper, we devote attention to the potential and limitations of data2activity traces, focusing on challenges and giving two examples to illustrate potential pitfalls in interpreting data. Finally, future research directions into data2activity traces are indicated that, in our opinion, should be given attention. These include development of future-proof data acquisition and storage methodology, enabling division-of-effort and sharing of information, as well as development of labeling methodology for free-living experiments.     

The use of COVID-19 contact tracing app data as evidence of a crime

This commentary draws attention to the introduction of data collected by COVID-19 tracing apps as evidence in criminal proceedings and the novel considerations this evidence presents for criminal justice agents and digital forensics professionals.     

技术权威与数字时代的国际技术竞争

在国际技术竞争中，技术权威既非构建于利益交换关系之上，又不依靠强制胁迫的方式来维系，而是通过锁定技术发展轨道与治理规则路径赢得其他国家的自愿追随，由此形成非对称服从关系。技术权威可划分为知识型、监管型、辐射型与借力型四种类型，不同技术权威类型之间可通过技术跃迁与市场规模拓展来实现转换。在移动通信技术领域，拥有不同技术权威类型的国家分别通过实体路径、市场路径、制度路径与联盟路径参与国际技术竞争，借助技术领域中的锁定效应巩固其在国际技术竞争中的优势地位，直至出现颠覆性技术的突破。
