Monero is the largest cryptocurrency with built-in cryptographic privacy features. The transactions are authenticated using spend proofs, which provide a certain level of anonymity by hiding the sourc...
SANNS: Scaling Up Secure Approximate k-Nearest Neighbors Search
nearest neighbor search privacy-preserving data analysis
2019/4/10
We present new secure protocols for approximate kk-nearest neighbor search (kk-NNS) over the Euclidean distance in the semi-honest model. Our implementation is able to handle massive datasets efficien...
ACCESSIBILITY ASSESSMENT: TRAINING THE SLUM RESIDENTS IN SCALING THE ‘ACCESSIBILITY’
Informal habitat planning dualism Accessibility ODK smart Quantum GIS
2019/2/27
With almost half of the developing world turning ‘urban’, it becomes a major challenge for the local self-governments to assure availability and accessibility of basic infrastructural facilities to ci...
PolyShard: Coded Sharding Achieves Linearly Scaling Efficiency and Security Simultaneously
Blockchain Coded Sharding Efficiency Scaling
2018/11/8
Today’s blockchains do not scale in a meaningful sense. As more nodes join the system, the efficiency of the system (computation, communication, and storage) degrades, or at best stays constant. A lea...
An important initialization step in many social-networking applications is contact discovery, which allows a user of the service to identify which of its existing social contacts also use the service....
Secure authentication and authorization within Facebook’s infrastructure play important roles in protecting people using Facebook’s services. Enforcing security while maintaining a flexible and perfor...
