摘要： Cloud data storage systems, methods, and techniques partition system data symbols into predefined-sized groups and then encode each group to form corresponding parity symbols, encode all data symbols into global redundant symbols, and store each symbol (data, parity, and redundant) in different failure domains in a manner that ensures independence of failures. In several implementations, the resultant cloud-encoded data features both data locality and ability to recover up to a predefined threshold tolerance of simultaneous erasures (unavailable data symbols) without any information loss. In addition, certain implementations also feature the placement of cloud-encoded data in domains (nodes or node groups) to provide similar locality and redundancy features simultaneous with the recovery of an entire domain of data that is unavailable due to software or hardware upgrades or failures.

摘要： Data storage techniques and solutions simultaneously provide efficient random access to information and high noise resilience. The amount of storage space utilized is only slightly larger than the size of the data. The solution is based on locally decodable error-correcting codes (also referred to as locally decodable codes or LDCs). Locally decodable codes are described herein that are more efficient than conventional locally decodable codes. Such locally decodable codes are referred to as “multiplicity codes”. These codes are based on evaluating multivariate polynomials and their derivatives. Multiplicity codes extend traditional multivariate polynomial based (e.g., Reed-Muller) codes. Multiplicity codes inherit the local decodability of Reed-Muller codes, and at the same time achieve substantially better parameters.
摘要翻译：数据存储技术和解决方案同时提供对信息的高效随机访问和高噪声弹性。所使用的存储空间量仅略大于数据的大小。该解决方案基于本地可解码的纠错码（也称为本地可解码或最不发达国家）。这里描述的本地可解码代码比传统的本地可解码的代码更有效。这样的本地可解码被称为“多重码”。这些代码基于评估多元多项式及其导数。多重码扩展了基于传统的多元多项式（例如里德 - 穆勒）码。多重代码继承了Reed-Muller代码的本地可解码性，同时实现了更好的参数。

摘要： First biometric parameters are acquired from a user. Input data are encrypted according to the biometric parameters to produce ciphertext. The biometric parameters are encoded using a syndrome encoder to produce a syndrome code. The ciphertext and the syndrome code are associated with each other and stored in a computer readable media so that only the same user can subsequently decrypt the cipher text.
