Abstract
A system and method for data quality analysis between untrusted parties is provided. A dataset having attributes each associated with one or more elements is maintained. An encrypted request is received from a client regarding data quality for one of the attributes. The encrypted request includes an interest vector of separately encrypted values identifying those elements of interest for the attribute. A condensed data vector representing the elements is generated for the attribute and is the same length as the interest vector. An aggregate of the elements of interest is determined by calculating for each element in the condensed data vector, an encrypted product of that element and a corresponding element of the interest vector and by determining a total product of all the encrypted products. A data quality value is assigned to the elements of the attribute in the dataset based on the aggregate.
