1. A computer-implemented method, the method comprising:
receiving a data query to request information on data for multiple patients;
assigning the data for the multiple patients into a plurality of patient groups in response to the data query, wherein each patient is assigned to a single group of the plurality of patient groups;
determining a forward deviation limit and a backward deviation limit for each of the patient groups based on a time deviation of patient data in the plurality of patient groups;
determining a deviation amount for one or more of the patients based on the determined forward deviation limit and the backward deviation limit, wherein a hash function provides security to information associated with the one or more patients; and
providing the data for the multiple patients including the determined deviation amount.
