US 11,228,566 B1 · System and method to anonymize data transmitted to a destination computing device

Abstract

A method and system for anonymizing data to be transmitted to a destination computing device is disclosed. Anonymization strategy for data anonymization is provided. Data to be transmitted is received from a user computer. Selective anonymization of the data is performed, based on the anonymization strategy, using an anonymization module. The data includes a plurality of characters. An order indicator data indicative of the order of the received data is generated. The received data is anonymized to derive an anonymized data. The anonymized data and the order indicator data is transmitted to the destination computer over a network. In one embodiment, a portion of the anonymized data is selected as a search ID. A cross reference between a search key indicative of a portion of the received data and the corresponding search ID is stored.

Dependent claims

A method for anonymizing data to be transmitted to a destination computing device, comprising:

receiving data to be transmitted to the destination from a user computer, the data including a plurality of characters defining a clear data in a first base encoding scheme;
anonymizing the data using an anonymization module to derive an interim anonymized data in a different second base encoding scheme by at least using an initialization vector;
generating an order indicator data indicative of the order of the received clear data that corresponds to the anonymized data by using one or more order preserving anonymization functions such that the order indicator data preserves the order of the clear data after de-anonymizing the anonymized data using a regenerated initialization vector to derive the clear data;
and
transmitting the order indicator data along with the anonymized data to the destination computing device over a network.
