Abstract
Embodiments of the present invention relate to searching for secret data through an untrusted searcher without exposing the secret data. In one embodiment, a method of and computer program product for searching for secret data through an untrusted searcher is provided. A secret value is read from a storage medium. The secret value is divided into a plurality of portions. Each of the plurality of portions is ranked. A subset of the secret value is determined from the ranking of the plurality of portions. A search string is constructed from the subset. The search string is transmitted to a searcher via a network. Search results are received from the searcher via the network. The search results are compared to the secret value to determine whether the searcher found the secret value.
