A global digital identity for all: the next evolution

Abstract

This paper chronicals the emergence of digital identity as a legal concept, how digital identity has grown in importance at the national level over the past decades and is now poised to become even more important internationally. This work builds on existing scholarship, to consider the next evolution of digital identity from what is now essentially a national concept into a global, legal concept. The examination looks to the likely emergence of a global digital identity for individuals in the near future and asks how that could be achieved. The authors examine the use of blockchain technology as a possible foundation of a global digital identity, along with the necessary development of existing international law on individual rights to support a global digital identity for all. Blockchain is viewed as relatively more secure and it enables individuals to have more control over how their identity information is managed and used. Blockchain’s traceability provides advantages for government and the private sector in managing and verifying identity. It aids the integrity of identity information and related transactions. However, it is important to note that, while blockchain has advantages, its relative immutability can lead to the creation and use of false digital identities that cannot be easily detected or corrected. As this paper discusses, this aspect can undermine the integrity and reliability of digital identity nationally and internationally. Given that blockchain technology is fallible, the authors argue that international law has a vital role now and in the future in recognizing the right to digital identity and establishing norms of conduct.
