浅谈数码影像证据在刑事诉讼中的运用

数码影像技术日趋成熟,其应用的领域也越来越广泛,我国公安、司法机关在实践中应用数码影像证据的实例也在增多.它在各类刑事案件中,对揭露犯罪、证实犯罪和打击犯罪发挥着越来越大的作用.然而,数码影像具有易伪造、易修改的特点,人们对数码影像技术还存在着一定的怀疑态度.如何有效保证数码影像证据在刑事诉讼中的运用就显得极为关键.     

电子商务中的认证技术

认证技术是保证电子商务安全的重要技术手段,是防止信息被篡改、删除、重放和伪造的一种有效方法,它具有被验证的能力,使接收者能够识别和确认消息的真伪。常用的安全认证技术主要有数字证书、数字签名、数字信封等。文中分析了电子商务的这几种认证技术。     

Digital Forensics as a Service: A game changer

How is it that digital investigators are always busy and still never have enough time to actually dig deep into digital evidence? In this paper we will explore the current implementation of the digital forensic process and analyze factors that impact the efficiency of this process. Next we explain how in the Netherlands a Digital Forensics as a Service implementation reduced case backlogs and freed up digital investigators to help detectives better understand the digital material.     

刑事诉讼中图像电子证据的举证、质证和认证

在日常生活和刑事侦查、刑事审判中,电子形式的图像证据已经成为主流,因而应对这种与传统图像证据截然不同的新兴证据形态,必须从证据规则、证明过程等角度进行全新的探索。图像电子证据的证据能力和证明力的认定,具有鲜明的技术特征,为证据规则和刑事证明的理论提供了新鲜的内容。     

数字经济范式与工作关系变革

数字经济的发展带来了自工业革命以来最深刻的社会变革。它对传统雇佣关系或工作关系产生了重大影响,使得岗位职责和技能更精确,工作场所不再受限,工作时间也更自由。同时,数字技术的应用,也不断推动各领域进行组织管理变革,使得劳动关系发生分化。为了更好地应对数字技术和数字经济的发展,政府应该适应技术创新与商业创新,并遵循既定的目标与原则进行制度创新。     

Copyright in the blockchain era: Promises and challenges

The paper focuses on various legal-related aspects of the application of blockchain technologies in the copyright sphere. Specifically, it outlines the existing challenges for distribution of copyrighted works in the digital environment, how they can be solved with blockchain, and what associated issues need to be addressed in this regard. It is argued that blockchain can introduce long-awaited transparency in matters of copyright ownership chain; substantially mitigate risks of online piracy by enabling control over digital copy and creating a civilized market for “used” digital content. It also allows to combine the simplicity of application of creative commons/open source type of licenses with revenue streams, and thus facilitate fair compensation of authors by means of cryptocurrency payments and Smart contracts. However, these benefits do not come without a price: many new issues will need to be resolved to enable the potential of blockchain technologies. Among them are: where to store copyrighted content (on blockchain or “off-chain”) and the associated need to adjust the legal status of online intermediaries; how to find a right balance between immutable nature of blockchain records and the necessity to adjust them due to the very nature of copyright law, which assigns ownership based on a set of informal facts, not visible to the public. Blockchain as a kind of time stamping service cannot itself ensure the trustworthiness of facts, which originate “off-chain”. More work needs to be done on the legal side: special provisions aimed at facilitating user's trust in blockchain records and their good faith usage of copyrighted works based on them need to be introduced and transactions with cryptocurrencies have to be legalized as well as the status of Smart contracts and their legal consequences. Finally, the economics of blockchain copyright management systems need to be carefully considered in order to ensure that they will have necessary network effects. If those issues are resolved in a satisfactory way, blockchain has the potential to rewrite how the copyright industry functions and digital content is distributed.     

数字治理对城市政府善治的影响研究

新公共管理运动和信息技术的发展推动了城市政府治理模式的变革“,善治”成为城市政府治理模式进化的方向。同时,在信息技术和电子政务的推动下,数字治理应运而生,成为信息社会实现城市政府善治的新思路。在对城市政府善治和数字治理进行全面阐释的基础上,构造数字治理环境下城市治理主体互动模式模型、城市网络治理结构模型;结合善治和城市政府善治的基本要素,对数字治理在城市政府善治中的作用进行了深入探讨。研究表明,数字治理借助其强大的技术优势,能形成良好的网络治理结构,加固城市政府善治的合法性基础,增强城市政府的透明性与回应性,明确城市治理主体的责任性,从而能够构建有效的城市政府善治机制,成为数字时代城市政府善治的理想选择。
