Abstract
Methods are provided for discovering related attributes with respect to an element in a customer data record, based on provided associations and for generating new associations between various elements of the customer data record. In these method, the context service system obtains, from a subscriber, a lookup request including a first blinded attribute. The first blinded attribute is obtained by applying an oblivious pseudo random function (OPRF) to a first element of a data record. The method further includes the context service system identifying at least one second blinded attribute associated with the first blinded attribute in a shared data partition of the context service system and providing, to the subscriber, at least one second element of the data record associated with the at least one second blinded attribute.
