A 2-server Private Information Retrieval (PIR) scheme allows a user to retrieve the i th bit of an n-bit database replicated among two noncommunicating servers, while not revealing any …
Locally decodable codes are error-correcting codes that admit efficient decoding algorithms; any bit of the original message can be recovered by looking at only a small number of …
An (r,δ,ϵ)-locally decodable code encodes ak-bit message x to an N-bit codeword C(x), such that for every i∈k, the i th message bit can be recovered with probability 1-ϵ, by a …
An information-theoretic private information retrieval (PIR) protocol allows a client to retrieve the i-th bit of a database, held by two or more servers, without revealing information about i …
In this work, we present the first local-decoding algorithm for expander codes. This yields a new family of constant-rate codes that can recover from a constant fraction of errors in the …

Private information retrieval (PIR) allows a client to retrieve any block xi from a database x= x 1 xn such that i remains hidden from the database servers. PIR• protocols with unconditional …
