The authenticity crisis
Computer Law & Security Review(2024)
摘要
Authenticity of information is a term with a clear meaning, not in law, but in the area of information security. There, it involves two aspects, called source-authenticity and message-authenticity; they guarantee certainty about the origin of information, and about its integrity. Authenticity differs from veracity: whether information is true (holds) or not is independent of its authenticity. The authenticity crisis described in the title of this paper refers to the destabilising impact of the lack of authenticity of online information, for instance in fake news. The paper proposes systematic use of digital signatures to guarantee authenticity. A crucial point is that authenticity may be organised via technical means (namely via digital signatures), whereas veracity can not. Authenticity-guarantees make institutions recognisable online and provide people with useful tools for making their own credibility judgements.
