In a nutshell, both types of signature schemes allow to alter signed data in a controlled way by a, potentially semi-trusted, third party. The resulting signatures still verify. Thus, the authenticity of the subsequently modified content is preserved. In this position paper, we discuss the state-of-the-art, and highlight potential future research opportunities. We hope this work gives rise to additional ideas, real-life use-cases, and interesting upcoming research, helping to bring both primitives into practice. Hence, this paper is meant as a starting point for readers interested in these primitives, looking for new research and application opportunities. In other words, we think that both primitives deserve further attention.<\/p>\n<p><strong>Venue\u00a0<\/strong><\/p>\n<p>Workshop on Security, Privacy, and Identity Management in the Cloud (SECPID 2017) (https:\/\/www.ares-conference.eu\/workshops\/secpid-2017\/)<\/p>\n<p><strong>Place and Date<\/strong><\/p>\n<p>Reggio Calabria, Italy.
