A comprehensive and efficient p-based algorithm is being proposed to retrieve minimum and maximum of particular data field of database tuple distributed as a horizontal partitioning of single database table among the multiple servers without losing the privacy of individual server. Data obfuscation technique is used in the proposed algorithm to preserve the privacy of individual server. This algorithm is useful in many practical scenarios where privacy-preserving data computing is desirable.
