ABSTRACT
<p><b>Abstract</b>—A file in a distributed database system is replicated on <it>M</it> sites and may contain corrupted pages. Abdel-Ghaffar and El Abbadi gave a detection scheme assuming that the number of corrupted pages <it>f</it> < <it>M</it> / 2. We replace this assumption by a much weaker one, that, for each page, the majority of copies are correct. Our schemes are based on the structure of the Reed-Solomon code, as proposed by Abdel-Ghaffar and El Abbadi for <it>M</it> = 2.</p>
INDEX TERMS
Data consistency, data corruption, fault detection, file comparison, Reed-Solomon code.
