Geolocation with respect to persona privacy for the Allergy Diary app - a MASK study

Background: Collecting data on the localization of users is a key issue for the MASK (Mobile Airways Sentinel network: the Allergy Diary) App. Data anonymization is a method of sanitization for privacy. The European Commission's Article 29 Working Party stated that geolocation information is personal data. To assess geolocation using the MASK method and to compare two anonymization methods in the MASK database to find an optimal privacy method. Methods: Geolocation was studied for all people who used the Allergy Diary App from December 2015 to November 2017 and who reported medical outcomes. Two different anonymization methods have been evaluated: Noise addition (randomization) and k-anonymity (generalization). Results: Ninety-three thousand one hundred and sixteen days of VAS were collected from 8535 users and 54,500 (58. 5%) were geolocalized, corresponding to 5428 users. Noise addition was found to be less accurate than k-anonymity using MASK data to protect the users' life privacy. Discussion: k-anonymity is an acceptable method for the anonymization of MASK data and results can be used for other databases.Peer reviewe

Participation and power: poor people's engagement with India's Employment Assurance Scheme

‘Participation’ has become an essential part of good developmental practice for Southern governments, NGOs and international agencies alike. In this article we reflect critically on this shift by investigating how a ‘participatory’ development programme — India's Employment Assurance Scheme (EAS) — intersects with poor people's existing social networks. By placing the formalized process of participation in the EAS within the context of these varied and uneven village–level relationships, we raise a number of important issues for participatory development practice. We note the importance of local power brokers and the heterogeneity of ‘grassroots’ (dis)empowerment, and question ideas of power reversals used within the participatory development literature
