越来越多的客户将数据存储外包给负责妥善保存数据的远程归档服务提供商。因此，档案服务机构必须能够提供证据，证明其负责的数据从收到数据之时起直至存档期届满期间的完整性。提出了一种基于配对的可证明数据完整性（PDI）方案，该方案不仅允许客户而且允许第三方验证者检查远程数据的完整性。该PDI方案是可证明安全和有效的。与最知名的现有技术相比，我们在限定条件下的实验表明，我们的PDI方案在对数据进行指纹识别时的工作速度快50倍，并且所得指纹的大小小30倍。
More and more customers are outsourcing data storage to remote archive service providers that are responsible for properly preserving the data. As such, it has become crucial for an archive service to be capable of providing evidence to demonstrate the integrity of data for which it is responsible, from the time it receives the data until the expiration of the archival period. Pairing-based provable data integrity (PDI) scheme is proposed that enables not only the customer but also a third-party verifier to check remote data integrity. This PDI scheme is provably secure and efficient. Compared to the best-known prior art, our experiments under defined conditions show that our PDI scheme works 50 times faster in fingerprinting the data, and the resulting fingerprints are 30 times smaller in size.
