Efficient Synchronisation of Large Repositories

大量数据的准确性和维护对任何现代社会都至关重要。经济、卫生机构和行业，以及我们的国防和法律的系统都依赖于广泛而安全地分发数据，以及准确而快速地回答查询。 由于互联网带宽的限制，数据库的完全同步通常是不可能的。更好的压缩技术有可能使关键数据更有效地分发;我们预计在某些应用程序中，与以前的最佳方法相比，压缩文件的大小可以减少十倍或更多，从而节省大量资金。

Accuracy and maintenance of vast quantities of data are essential for any modern society. The economy, health institutes and industries, and our defence and legal systems rely on having data being distributed widely and securely, and on queries being answered accurately and quickly. Complete synchronisation of databases is often impossible due to the limitations of internet bandwidth. Better compression techniques have the potential to allow critical data to be distributed much more efficiently; we anticipate in some applications that the size of a compressed file could be reduced tenfold or more compared to previous best methods, leading to dramatic savings.
