The mammalian brain is best understood as a multi-scale hierarchical neural system, in the sense that connection and function occur on multiple scales from micro to macro. Modern genomic-scale expression profiling can provide insight into methodologies that elucidate this architecture. We present a methodology for understanding the relationship of gene… (More)
We extend the searchable symmetric encryption (SSE) protocol of [Cash et al., Crypto'13] adding support for range, substring, wildcard, and phrase queries, in addition to the Boolean queries supported in the original protocol. Our techniques apply to the basic single-client scenario underlying the common SSE setting as well as to the more complex… (More)
As fast and accurate sequencing of human genomes becomes affordable, it is expected that individuals will soon be able to carry around copies of their sequenced DNA, using it for medical, identification, and social purposes. This will undoubtedly prompt a wide range of new and interesting genomic applications. However, the very same progress raises some… (More)
Recent progress in genomics and bioinformatics is bringing complete and on-demand sequencing of human (and other) genomes closer and closer to reality. Despite exciting new opportunities, affordable and ubiquitous genome sequencing prompts some serious privacy and ethical concerns, owing to extreme sensitivity and uniqueness of genomic information. At the… (More)
Balancing security and privacy concerns with information sharing is a top priority for corporations, law enforcement agencies, governments, and other organizations. Secure pattern matching (SPM) addresses some of the challenges faced in sharing and searching private data.
The recent decade has witnessed a rapid increase in popularity of mobile personal devices (notably, smartphones) t hat function as all-purpose personal communication portals. Concurrently, On-line Social Networks (OSNs) have continued their impressive proliferation. Meanwhile, the notion of "OSN privacy" remains elusive and even self-contradictory.… (More)
Private Set Intersection (PSI) and other private set operations have many current and emerging applications. Numerous PSI techniques have been proposed that vary widely in terms of underlying cryptographic primitives, security assumptions as well as complexity. One recent strand of PSI-related research focused on an additional privacy property of hiding… (More)
