How do we provide the digital footprint with eternal rest? Some criteria for legislation regulating digital wills

This article analyses the implications of the death of digital service users on their digital footprint and assesses some of the solutions—contractual and legislative—that have been posited to date by digital service providers and by Parliaments of a few countries. In view of the different initiatives analysed, and the experience gained in their implementation, the paper presents legal certainty, effectiveness and transparency as criteria that should guide the regulation of the digital footprint in the case of death. These criteria must allow for the adoption or regulation of mechanisms for managing the digital footprint of digital service users to be clear and trustworthy for them and efficient and easily recognized and adopted by digital service providers.

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.     

Digital evidence and the crime scene

Many criminal investigations maintain an element of digital evidence, where it is the role of the first responder in many cases to both identify its presence at any crime scene, and assess its worth. Whilst in some instances the existence and role of a digital device at-scene may be obvious, in others, the first responder will be required to evaluate whether any ‘digital opportunities’ exist which could support their inquiry, and if so, where these are. This work discusses the potential presence of digital evidence at crime scenes, approaches to identifying it and the contexts in which it may exist, focusing on the investigative opportunities that devices may offer. The concept of digital devices acting as ‘digital witnesses’ is proposed, followed by an examination of potential ‘digital crime scene’ scenarios and strategies for processing them.

Defining event reconstruction of digital crime scenes

Event reconstruction plays a critical role in solving physical crimes by explaining why a piece of physical evidence has certain characteristics. With digital crimes, the current focus has been on the recognition and identification of digital evidence using an object's characteristics, but not on the identification of the events that caused the characteristics. This paper examines digital event reconstruction and proposes a process model and procedure that can be used for a digital crime scene. The model has been designed so that it can apply to physical crime scenes, can support the unique aspects of a digital crime scene, and can be implemented in software to automate part of the process. We also examine the differences between physical event reconstruction and digital event reconstruction.

Toward a General Ontology for Digital Forensic Disciplines

Ontologies are widely used in different disciplines as a technique for representing and reasoning about domain knowledge. However, despite the widespread ontology‐related research activities and applications in different disciplines, the development of ontologies and ontology research activities is still wanting in digital forensics. This paper therefore presents the case for establishing an ontology for digital forensic disciplines. Such an ontology would enable better categorization of the digital forensic disciplines, as well as assist in the development of methodologies and specifications that can offer direction in different areas of digital forensics. This includes such areas as professional specialization, certifications, development of digital forensic tools, curricula, and educational materials. In addition, the ontology presented in this paper can be used, for example, to better organize the digital forensic domain knowledge and explicitly describe the discipline's semantics in a common way. Finally, this paper is meant to spark discussions and further research on an internationally agreed ontological distinction of the digital forensic disciplines. Digital forensic disciplines ontology is a novel approach toward organizing the digital forensic domain knowledge and constitutes the main contribution of this paper.     

The accountability of non-governmental actors in the digital sphere: A theoretical framework

The last decade has seen increasing demands for greater accountability in digital governance. What, however, does accountability require and what normative goods does it serve? This article develops a general framework for assessing digital accountability focused on four normative goods: openness, non-arbitrariness, effectiveness and publicness. As the article will evidence, claims for digital accountability often refer to deficits relating to one or more of these goods. While scholarly attention has deservedly focused on tying powerful digital actors to rule of law guarantees, the article argues that accountability offers an important normative yardstick to allow citizens to contest digital decisions beyond strict legality. The framework therefore provides a basis for both conceptually disaggregating and normatively forwarding accountability claims in the digital sphere.     

数字证据的程序法定位--技术、经济视角的法律分析

基于证据在程序中的重要地位以及证据与社会发展息息相关的紧密关联,要促进程序法在数字时代的发展,首先要研究的便是数字技术对包括民事、行政、刑事证据在内的程序证据制度的影响.使用"计算机证据"、"电子证据"概念并不能科学地归纳出这种证据的内涵,而"数字证据"概念则更符合其本质特征.在证据类型上,数字证据与书证、视听资料等已有证据类型颇不相同,是一种新的独立的证据类型,并且,在证据规则上,数字证据具有与其数字技术特性相应的新规则.

Planning for the succession of digital assets

Estate planners’ current strategies for the disposition of digital assets are quickly becoming out-dated. This is largely the result of ambiguities concerning proprietary rights of digital assets after death. When advising clients on how to plan for the succession of digital assets, it is important for estate planners to understand the nature of digital assets today and to recognize how these assets may evolve. In failing to take into account the evolving nature of digital assets, estate planners are liable to craft short-sighted and thus ineffective succession plans. As the popularity of digital executor businesses increases, estate planners ought to caution clients on their shortcomings. Additionally, legislatures must create statutes which outline the rights of individuals vis-à-vis online service providers.     

Digital identity – From emergent legal concept to new reality

Over the past decade, digital identity has gone from a largely unrecognized emergent legal concept to something that is now well known, but still not fully understood. Most individuals now know that they have a digital identity but its legal nature, its transactional functions, and its implications now and for the future, are not generally well understood.This article tracks the emergence of digital identity from the time it was recognized as a new legal and commercial concept to the present time; and outlines its impact and significance for individuals, governments, the private sector and even what is means to be a nation and a citizen in the digital era. The author recounts her experience in recognizing the implications of digital identity in 2006 to its current importance and the implications of future evolutions including an international digital identity, the groundwork for which is being laid now.     

The impact of student-generated digital flashcards on student learning of constitutional law

This article describes, evaluates and reflects upon student creation of cloud-based digital flashcards as an authentic formative and summative assessment task designed for the deep learning of constitutional law. The usefulness of digital flashcards in online legal education is explored. The undergraduate law student participants in the study responded differently to the assessment task depending upon the constitutional law topic they were assigned, the perceived relevance of constructing digital flashcards to professional practice and how they reacted to this creative task. Building digital flashcards provides a potentially powerful authentic assessment task for the study of constitutional law provided it is designed to support semester long creation, validation and sharing of digital flashcards that students perceive as professionally relevant and educationally useful. Student recommendations for designing an assessment task involving the creation of digital flashcards are evaluated.     

Study on the standard components of digital forensics laboratory

Recently, digital forensics has become increasingly important as it is used by investigation agencies, corporate, and private sector. To supplement the limitations of evidence capacity and be recognized in court, it is essential to establish an environment that ensures the integrity of the entire process ranging from collecting and analyzing to submitting digital evidence to court. In this study, common elements were extracted by comparing and analyzing ISO/IEC 17025, 27001 standards and Interpol and Council of Europe (CoE) guidelines to derive the necessary components for building a digital forensic laboratory. Subsequently, based on 21 digital forensic experts in the field, Delphi survey and verifications were conducted in three rounds. As a result, 40 components from seven areas were derived. The research results are based on the establishment, operation, management, and authentication of a digital forensics laboratory suitable for the domestic environment, with added credibility through collection of the opinions of 21 experts in the field of digital forensics in Korea. This study can be referred to in establishing digital forensic laboratories in national, public, and private digital forensic organizations as well as for employing as competency measurement criteria in courts to evaluate the reliability of the analysis results.     

When finding nothing may be evidence of something: Anti-forensics and digital tool marks

There are an abundance of measures available to the standard digital device users which provide the opportunity to act in an anti-forensic manner and conceal any potential digital evidence denoting a criminal act. Whilst there is a lack of empirical evidence which evaluates the scale of this threat to digital forensic investigations leaving the true extent of engagement with such tools unknown, arguably the field should take proactive steps to examine and record the capabilities of these measures. Whilst forensic science has long accepted the concept of toolmark analysis as part of criminal investigations, ‘digital tool marks’ (DTMs) are a notion rarely acknowledged and considered in digital investigations. DTMs are the traces left behind by a tool or process on a suspect system which can help to determine what malicious behaviour has occurred on a device. This article discusses and champions the need for DTM research in digital forensics highlighting the benefits of doing so.

Taxonomy of Challenges for Digital Forensics

Since its inception, over a decade ago, the field of digital forensics has faced numerous challenges. Despite different researchers and digital forensic practitioners having studied and analysed various known digital forensic challenges, as of 2013, there still exists a need for a formal classification of these challenges. This article therefore reviews existing research literature and highlights the various challenges that digital forensics has faced for the last 10 years. In conducting this research study, however, it was difficult for the authors to review all the existing research literature in the digital forensic domain; hence, sampling and randomization techniques were employed to facilitate the review of the gathered literature. Taxonomy of the various challenges is subsequently proposed in this paper based on our review of the literature. The taxonomy classifies the large number of digital forensic challenges into four well‐defined and easily understood categories. The proposed taxonomy can be useful, for example, in future developments of automated digital forensic tools by explicitly describing processes and procedures that focus on addressing specific challenges identified in this paper. However, it should also be noted that the purpose of this paper was not to propose any solutions to the individual challenges that digital forensics face, but to serve as a survey of the state of the art of the research area.     

法律数字化现象研究

法律的数字化是一个值得关注但至今尚未被充分关注的现象.法律与数字相结合的内在机理体现在两方面:现实存在的模糊性导致我们必须通过数字化的形式以达致认识的精确性,而现实存在的秩序性使得通过数字化的形式来表达法律成为可能；数字的格式化特征与法律所追求的客观性不谋而合,而法律所需要的可操作性恰可借助数字的工具功能得以满足.数字化是法律形式化的主要实现途径,数字赋予了法律以科学性、客观性及正当性,法律的数字化可有效地规范自由裁量权.法律对数字的过度依赖也容易导致实质上的不平等,且将会引发功利主义的泛滥.法律的工具理性需要数字化,而人性则是无法数字化的.法律的数字化只能是有限的、相对的.
