A Private Information Retrieval (PIR) scheme is a protocol in which a user retrieves a record out of N from a replicated database, while hiding from the database which record has been retrieved, as long as the different replicas do not collude. A specially interesting sub-field of research, called singledatabase PIR, deals with the schemes that allow a user to retrieve privately an element of a...

The goal of Private Information Retrieval (PIR) is for a client to query a database in such a way that no one, including the database operator, can determine any information about the desired database record. Many PIR schemes have been developed, but are generally not deemed fast enough for client needs in today’s fast-paced world or do not scale well to large databases. We implement a parallel...

The NF-κB family of transcription factors controls a number of essential cellular functions. Pirin is a non-heme iron (Fe) redox specific co-regulator of NF-κB (p65) and has been shown to modulate the affinity between the homodimeric p65 and the DNA. The allosteric effect of the active Fe(III) form of Pirin on the DNA is not known and has not been investigated. We carry out multiple microsecond...

Purpose: To evaluate the association between platelet inhibition rate of clopidogrel (CLO-PIR) and post-extraction clotting status in DAPT patients.
 Methods: Ninety (90) eligible patients scheduled for a single tooth extraction were enrolled this study. The CLO-PIR aspirin (ASA-PIR) determined by thromboelastography mapping assay. Post-extraction assessments performed, complete intra-alve...

Plain English summary The article analyses the process of securing permissions for members of the public (we refer to them as "research partners") and academics involved in a qualitative study of public involvement in research (PIR) across eight health sciences projects in England and Wales. All researchers, including research partners, need to obtain a "research passport" from UK NHS trusts wh...

A private information retrieval (PIR) scheme on coded storage systems with colluding, byzantine, and nonresponsive servers is presented. Furthermore, the scheme can also be used for symmetric PIR in the same setting. An explicit scheme using an [n, k] generalized Reed-Solomon storage code is designed, protecting against t-collusion and handling up to b byzantine and r non-responsive servers, wh...

We present PRISM, a privacy-preserving scheme for word search in cloud computing. Assuming a curious cloud provider, privacy of data stored in the cloud becomes an issue. The main challenge in the context of cloud computing is to design a scheme that achieves privacy while preserving the efficiency of cloud computing. Main approaches like simple encryption, Private Information Retrieval (PIR) a...

Private Information Retrieval (PIR) allows a client to obtain data from a public database without disclosing the locations accessed. Traditionally, the stress is on preserving sublinear work for the client, while the server’s work is taken to inevitably be at least linear in the database size. Beimel, Ishai and Malkin (JoC 2004) show PIR schemes where, following a linear-work preprocessing stag...

Private Information Retrieval (PIR) allows a user to retrieve bits from a database while hiding the user’s access pattern. However, the practicality of PIR in a real-world cloud computing setting has recently been questioned. In such a setting, PIR’s enormous computation and communication overhead is expected to outweigh the cost saving advantages of cloud computing. In this paper, we first exa...
