"Specifically, the review focuses on the means, barriers, and associated cybersecurity and privacy concerns that refugees face around connectivity. This includes but is not limited to mobile connectivity and social media, particularly in displacement contexts. While these subjects may at times intersect with parallel conversations on digital identity or biometrics, the latter are not the focus of this chapter. UNHCR provides support and international protection to forcibly displaced persons, including refugees, returnees, stateless people, the internally displaced and asylum-seekers. This report will reference ‘refugees’ and this can be read broadly to encompass refugees and other persons of concern, unless explicity stated otherwise. This literature review is divided into different sub-themes. An annex also provides a brief overview of who are the main actors writing about connectivity in humanitarian contexts, and with what angles and / or interests." (Introduction)
