Disclosed herein are system, method, and computer program product embodiments for secure data aggregation in databases. An embodiment operates by identifying a value column and a group column of a plurality of columns of a dataset. Two distinct group values of the group column are identified. A first group value is replaced with a first substitute value, and a second group value is replaced with a second substitute value. A value of the value column of each of the plurality of records and the substitute values are encrypted. The plurality of encrypted records are uploaded to a server.

Secure data aggregation in databases using dynamic bucketization and grouping bucketization

Disclosed herein are system, method, and computer program product embodiments for secure data aggregation in databases. An embodiment operates by identifying a value column and a group column of a plurality of columns of a dataset. Two distinct group values of the group column are identified. An offset value corresponding to the first group value is determined. One or more of the plurality of records including the first group value are identified. A value of the value column of each of the identified one or more plurality of records is encoded with the offset value. Values of the encoded value column are encrypted. The encrypted values are uploaded to a server.
