INTRODUCTION An unaccompanied 15-year-old girl presents to a local emergency department (ED) with abdominal pain, but at triage does not reveal her concern that she may have a sexually transmitted infection (STI). She is seeking care in the ED instead of her primary care medical home because she believes her visit will be confidential. Upon ED arrival, the youth explains her symptoms to a nurse...

Confidential Transactions (CT) hide coin amounts even from verifiers without the help of trusted third parties. Aggregable CTs are a scalable category with “spent record trimming”. For example, if Alice sends coins to Bob, who had sent similar Charles, aggregated transaction shows only that Charles by deleting Bob’s records. Since number spent records grows linearly transactions, faster than ac...

High-performance computing (HPC) in the public cloud democratizes supercomputing power that most users cannot afford to purchase and maintain. Researchers have studied its viability, performance, usability. However, HPC has a unique feature—users export data computation somewhat untrusted platforms. Users will either fully trust providers protect from all kinds of attacks or keep sensitive asse...

We demonstrate that, by using a recently proposed leveled homomorphic encryption scheme, it is possible to delegate the execution of a machine learning algorithm to a computing service while retaining confidentiality of the training and test data. Since the computational complexity of the homomorphic encryption scheme depends primarily on the number of levels of multiplications to be carried ou...
