Method for outsourcing data for secure processing by untrusted third parties
First Claim
1. A method for processing data generated based on events having a first dimension, a second dimension and a quantity, comprising:
- generating a random value for each interval of the first dimension and each instance of the second dimension;
adding the random value to the quantity of each event to determine a modified quantity;
determining a running total for each interval of the first dimension and each instance of the second dimension using the modified quantities;
transmitting the modified quantities and the running totals to an untrusted third party; and
receiving an exact result of processing the modified quantities and the running totals by the untrusted third party, wherein the steps are performed in real time by a client.

Abstract
Data is generated in a client based on events at a client, wherein each event is associated with a first dimension, a second dimension and a quantity. A random value is generated for each interval of the first dimension and each instance of the second dimension. The quantity of each event is modified using the random value to determine a modified quantity. A running total for each interval of the first dimension and each instance of the second dimension is determined using the modified quantities and transmitted to an untrusted third party. An exact result of processing the modified quantities and the running totals by the untrusted third party can then be received and decoded by the client.
