Robust Distributed Source Coding with Arbitrary Number of Encoders and Practical Code Design Technique
The robustness property can be added to DSC system at the expense of reducing performance, i.e., increasing the sum-rate. The aim of designing robust DSC schemes is to trade off between system robustness and compression efficiency. In this paper, after deriving an inner bound on the rate–distortion region for the quadratic Gaussian MDC based RDSC system with two encoders, the structure of...
متن کاملSlepian-Wolf codes for parallel sources: design and error-exponent analysis∗
The distributed source coding problem, introduced by Slepian and Wolf, is finding application in diverse areas ranging from sensor networks to robust videocompression to compression of encrypted data. Such applications have led to a flurry of recent work in practical code constructions. However, most of these constructions are designed for independent identically distributed random source model...
متن کاملOn Blind Compression of Encrypted Data Approaching the Source
Traditional data transmission over an insecure noiseless channel consists of first compressing data for efficiency and then encrypting it for security. Reversing the order of these operations is considered in Johnson et al. The central realization is that while the raw and encrypted data are statistically independent, the encrypted data and key sequence are not. If distributed source coding tec...
متن کاملOn Blind Compression of Encrypted Correlated Data Approaching The Source Entropy Rate∗
Traditional data transmission over an insecure noiseless channel consists of first compressing data for efficiency and then encrypting it for security. Reversing the order of these operations is considered in Johnson et al. [1]. The central realization is that while the raw and encrypted data are statistically independent, the encrypted data and key sequence are not. If distributed source codin...
متن کاملSeparating indexes from data: a distributed scheme for secure database outsourcing
Database outsourcing is an idea to eliminate the burden of database management from organizations. Since data is a critical asset of organizations, preserving its privacy from outside adversary and untrusted server should be warranted. In this paper, we present a distributed scheme based on storing shares of data on different servers and separating indexes from data on a distinct server. Shamir...
