Abstract

The concept that a person aims to control my own identity without the intervention of a controlling entity is called self-sovereign identity (SSI). The SSI is an antithesis to the phenomenon that certain companies and organizations, called digital platformers, collect data centrally.

This paper expands the concept of SSI and describes the possibilities and problems when applying it to self-content management using the concept of Self-Content Management (SCM). In particular, I discuss the possibility of self-sovereign management of digital content, and discuss DRM using blockchain technology as a means.

This paper is assumed that SSI can be applied to content created by myself, but by properly managing content using blockchain technology, it is possible to complete licenses and levy fees. I also clarified that it could be a substitute for the resale right.

As a result, SCM promoted the problem of “orphans’ works” and facilitated the processing of rights, and revealed that it could contribute to the further development of culture. However, I also address that there are two issues. One is the lack of institutional trust, rather than the technical credibility of the blockchain. The second is consistency with the Attorney law of Japan.

    An information bank reliable entity to which a person delegates the provision of personal information to a third party to the extent that the person agrees, with the aim of promoting the distribution and use of personal data by enhancing effective personal involvement (controllability) (Ministry of Economy, Trade and Industry Study Group on Approaches to Certification Schemes for Information Trust Functions “Guideline on Authorization of Information Trust Functions ver. 2.0 [October 2019]”).

    Turning away from this discussion, the GDPR response in the blockchain, in particular the right to correct and the right to be forgotten, can be cleared by:

    In the real estate registration records of Japan, correction before and after correction, such as ex officio correction, is distinguished by an underline, so this should be followed. In other words, before and after the correction are clearly indicated. Since it is practically impossible to directly rewrite the original data before correction on a blockchain basis, the corrected information is written by specifying the corrected part.

    Next, in relation to the right to be forgotten, it is necessary to ensure that no corrections are left even in the right to correct mentioned above. For the time being, this response could be addressed by not granting any access privileges on a blockchain-based basis. However, if it is not observable ex post facto, the reliability cannot be maintained, so it is necessary to separate the data groups that exercised the right to be forgotten. In this way, it is possible to solve the problem. However, it is necessary to examine whether leaving traces of the exercise of the right to be forgotten is sufficient guarantee of the right to be forgotten.
