Fostering trustworthy data sharing: Establishing data foundations in practice

ASTRO: Autonomous and Trustworthy Data Sharing

We present ASTRO, a Byzantine fault tolerant data sharing service for mobile computing environments. ASTRO is the first system to support disconnected operation and opportunistic data sharing among potentially Byzantine nodes while continuing to provide precise and useful consistency guarantees to correct nodes. Specifically, ASTRO supports fork-causal consistency, a new consistency semantics t...

فعالیت های نگهداری و تعمیرات اطلاعاتی را تولید می کند که می تواند در تعیین زمان های بیکاری و ارایه یک برنامه زمان بندی شده یا تعیین هشدارهای خرابی به پرسنل نگهداری و تعمیرات کمک کند. وقتی که مقدار داده های تولید شده زیاد باشند، فهم بین متغیرها بسیار مشکل می شوند. این پایان نامه به کاربردی از داده کاوی برای کاوش پایگاه های داده چندبعدی در حوزه نگهداری و تعمیرات، برای پیدا کردن خرابی هایی که موجب...

Spatial Data Sharing: From Theory to Practice

VC3: Trustworthy Data Analytics in the Cloud

We present VC3, the first system that allows users to run distributed MapReduce computations in the cloud while keeping their code and data secret, and ensuring the correctness and completeness of their results. VC3 runs on unmodified Hadoop, but crucially keeps Hadoop, the operating system and the hypervisor out of the TCB; thus, confidentiality and integrity are preserved even if these large ...
