Our society increasingly relies on prompt, accurate delivery of information over the Internet. Users need assurance that the information they get in this way is authentic, and they need to get this assurance in a cheap and reliable way.The research centers around a new approach for engendering this confidence. The starting point is to separate the roles of the "owner" of a database and its "publisher" (or publishers). With this approach the user need not trust the publisher. Instead, the owner of the database provides the user with a small amount of "summary information". After that, the publisher not only answers the user's questions, but also provides, along with each answer, a short "digital certificate" of accuracy. Using the summary information, the certificate lets the user check that the information received is correct and complete. Developing and evaluating good schemes to construct these certificates is the key technical challenge.The publisher need not maintain a trusted system, lowering his cost of doing business. The publisher can also more easily provide information from multiple owners. Overall, the approach should make it cheaper to obtain reliable data over the Internet, and will expand the settings where the data is used.

我们的社会越来越依赖于通过互联网迅速、准确地传递信息。 用户需要保证他们通过这种方式获得的信息是真实的，他们需要以廉价和可靠的方式获得这种保证。 起点是将数据库的“所有者”及其“发布者”（或多个发布者）的角色分开。 使用这种方法，用户不需要信任发布者。 相反，数据库的所有者向用户提供少量的“摘要信息”。 在此之后，出版商不仅回答用户的问题，而且还提供，沿着每个答案，一个简短的“数字证书”的准确性。 使用摘要信息，证书允许用户检查接收到的信息是否正确和完整。 开发和评估构建这些证书的好方案是关键的技术挑战。发布者不需要维护一个可信系统，从而降低了做生意的成本。 出版商还可以更容易地提供来自多个所有者的信息。 总的来说，这种方法应该使通过互联网获得可靠数据的成本更低，并将扩大使用数据的环境。
