Abstract
There is provided a method for computing an encrypted prediction in response to an encrypted query, comprising: obtaining an encrypted dataset comprising encrypted records for respective encrypted entities, each record storing encrypted parameter values of parameters and an associated indication of the respective entity, computing abnormality clusters according to the records of the encrypted dataset, wherein each of the abnormality clusters stores indications of entities of records of the encrypted dataset having mathematically significant common abnormal feature(s) that statistically differentiates records of the respective abnormality cluster from other records of the encrypted dataset, receiving a query comprising target indications of respective target entities associated with common feature(s), and analyzing the query according to the abnormality clusters to identify at least one encrypted result entity indication according to a likelihood of the encrypted result entity indication predicted to correlate to the common feature(s) at a future time interval.
