Location-based access control systems for mobile users

Elisa Bertino, Michael S. Kirkpatrick
2011 Proceedings of the 4th ACM SIGSPATIAL International Workshop on Security and Privacy in GIS and LBS - SPRINGL '11  
Many organizations require that sensitive information only be accessed on the organization premises or in secure locations.  ...  Access to certain information is thus allowed to authorized users, provided that these users are in specific locations when accessing the information. The GEO-RBAC model addresses such requirement.  ...  Another critical issue is related to the definition and enforcement of a constraint language suitable for open spaces. • The integration of a proximity language with GEO-RBAC.  ...

Adversarial Stacked Auto-Encoders for Fair Representation Learning [article]

Patrik Joslin Kenfack, Adil Mehmood Khan, Rasheed Hussain, S.M. Ahsan Kazmi,
2021 arXiv   pre-print
Our results show that stacking different auto-encoders and enforcing fairness at different latent spaces result in an improvement of fairness compared to other existing approaches.  ...  Different types of learning methods are employed to map data into the fair representational space.  ...  The adversarial loss is to enforce the representation to satisfy certain fairness constraint.  ...
