Dear All, First of all, thank for allowing me to the group. I really appreciate Eve for her welcome note. I am Jabed, currently a PhD student at Swinburne University of Technology, Melbourne, Australia. My research interests are information security, Internet of things and cyber forensic. While I was working with my Phd research problem related to user based cross domain access control, I found Maciej's phd thesis. From his work, I learned about this working group. Our university research group is specialized in context-aware and adaptive computing. I am planning to extend UMA for context-awareness, specially for ubiquitous environment (pervasive and IoT enable). I am also interested to examine the privacy part of it. I have read about UMA from different available online documents. I have also downloaded and configured OpenUMA( from ForgeRock) to gain hands on experience. I am still learning about it. I hope to learn a lot from this group. I am also hopeful that I will get Eve and Maciej's expert guidance/feedback from time to time. Looking forward to collaborate. Best regards, Jabed
