Participant we use participant to refer to those choosing to participate in research, those where consent-waivers may be in place or where some stakeholders may fulfil participant-researcher roles (e.g., teachers), and those 'data subjects' whose data is used in research often without their knowledge. input into research should be appropriately protected, and acknowledged, and these may at times be in tension (or, perceived to be in tension where our default assumption is towards deidentification). These issues may become salient in new ways as generative AI emerges, and questions are addressed regarding protection of intellectual property and the burdens and benefits of training genAI.In research involving interaction with participants in which materials are produced as a part of the participation, we may seek to deidentify or aggregate data in order to minimise risks to participants of reidentification. However, this may not be appropriate in cases where either: - the data cannot be appropriately deidentified (for example, reverse image search means removing identifiers from a distinct image is unlikely to provide protection), or- where participants would like to be acknowledged for their input into the research. In these cases, there is potential for injustice in the representation of participants, and the burden and benefits of the research process. It may be appropriate to ask participants (or to invite them to give input on psuedonyms), there is some additional guidance in [Ethical Visual Research Methods](/recyweamynkerwieb).
