In this paper I probe the problems stem from the recent judgement of Japanese supreme court about a GPS investigation, and propose some ﬁxes to the problems in order to allow Japanese criminal justice to co-evolve with the rapid development of informational technologies and big data sciences. Particularly, I argue to introduce the idea of optimization of criminal justice in order to avoid being trapped by vague and helpless dogmatic of the right to privacy in this context. I reframe the right to privacy argument into the agency problem theory and propose the reasonable solution to it through informational technologies and big data sciences. But I also add some critiques to too much reliance on these new technologies from a kind of Foucauldian view for demonstrating the importance of democratic decision in criminal justice system.
In this paper, based on the economic characteristics of information goods, I conﬁrm what kind of market characteristics the media industry originally has, and examined how the new entry of net media inﬂuences the information goods market. First, I conﬁrm the characteristics of the supply side of media. Speciﬁcally speaking, I indicate that consumption of information goods has external effect on the users preference, so that the media market will be the two-sided market, and the composition of the media’s revenue depend on the relative relationship between advertisement effectiveness and consumer’s disutility of advertisement. Second, I conﬁrm the characteristics of the demand side of media. I show that the time-consuming cost and effort cost besides production cost are required on the consumption of the information goods. And how these costs inﬂuence effect on the user’s selection of contents is analyzed by the theoretical and empirical model. Finally, I discuss about the result of competition over attention in the information goods market due to new entries through the Internet. I point out that it becomes difficult to maintain the quality of information goods in advertising media and that there is a possibility that the separation between the pay media and the sponsored media may accelerate.
On December 14th, 2017, the FCC, led by Chairman Ajit Pai, who was appointed by the President Trump, adopted an order and fundamentally changed the framework of the net neutrality regulation that former FCC chairman Tom Wheeler strengthened by the Title II order. This is not only the result of the conﬂict over the meaning of net neutrality and its achievement method, but also the result of policy response to changes in the broadband ecosystem. This paper describes the transition of net neutrality regulations and analyzes the relation with the evolution of the broadband ecosystem behind it.
AI and Robots are tools created by humans, and are currently at the stage where they are nothing more than tools which only operate according to human intentions. However, if autonomous robots controlled by AI system come to be used everywhere in society, the associated legal issues should be given a thorough legal re-examination. If we fail to scrutinize the new information security countermeasures for the use of intelligent robots and artiﬁcially intelligent entities or if we fail to review the legal issues accompanying the spread of consumer electronics, robots equipped with AI, and cars that operate as highly automated vehicle systems, the types of security problems which have impacted the development of the Internet could arise again in other, new contexts that involve artiﬁcial intelligence. There is a fear that this danger will spread beyond the problems within ‘virtual spaces’ (such as the Internet), and present threats which will dramatically raise the likelihood of physical danger resulting from the actions caused by AI. The possibility of an AI running out of control and posing a danger to humans has been noted as one of the potential threats posed by robots that are becoming more and more autonomous. This paper focuses on the principal Japanese AI and Robot Law, strategy and research trend toward establishing basic principles that would be helpful for considering to conduct trials of such technologically innovative issues.
A large number of organizations in Japan are still not aware of or knowing the signiﬁcantly changing of attack mechanism. And those always look for security measure systems and method without facing actualities of cyber issue. This article mentions the importance of the situation awareness of cyber threat and noteworthy fact of attack mechanism, and then seeing deep into action items to be necessarily associated with or result in or involve.
This study includes 1) Introduction 2) The analysis of a contract about privacy from the viewpoint of substantive law, 3) The analysis of a contract about privacy from the viewpoint of procedural law, 4) The future discussion point of a contract about privacy. In Vol. (3), analysis of ‘privacy contract’ is discussed from the viewpoint of procedural law.
The deﬁnition of “Personal information
” in the Act on the Protection of Personal Information is one of the biggest issues in the discussion of the Personal data usage. To propose a solution for this discussion, I overview the history of the circumstances of establishment of ordinance for the protection of personal information in local governments and clarify the modiﬁcation of the deﬁnition of the subject. Key Word：Act on the Protection of Personal Information, Privacy, Personal Data
