摘要
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.
