Abstract: This work discuss real world deniability in messaging. We highlight how the different models for cryptographic deniability do not ensure practical deniability. To overcome this situation, we propose a model for real world deniability that takes into account the entire messaging system. We then discuss how deniability is (not) used in practice and the challenges arising from the design of a deniable system. We propose a simple, yet powerful solution for deniability: applications should enable direct modification of local messages; we discuss the impacts of this strong deniability property.
