System and method to anonymize data transmitted to a destination computing device
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. 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.
1. A method for anonymizing data to be transmitted to a destination computing device, comprising:
receiving data to be transmitted to the destination computing device from a user computer, the data including a plurality of characters;
anonymizing the data using an anonymization module to derive an anonymized data;
selecting a portion of the anonymized data as a search ID;
storing in a data store, a cross reference between a search key indicative of a portion of the received data and the corresponding search ID such that the search ID can be retrieved that corresponds to the search key which matches a search term in a search request for the anonymized data; and
transmitting anonymized data to the destination computing device over a network and in response to receiving the search request, selective anonymized data can thus be obtained based on the retrieved search ID that matches with the portion of the anonymized data such that the de-anonymized data can be returned as a response to the search request.
2. The method of claim 1 , further including:
receiving a request to search the anonymized data stored at the destination computing device, using a search term;
retrieving search ID that corresponds to the search key matching the search term;
sending a search request to the destination computing device to retrieve selective anonymized data wherein the search ID matches with the portion of the anonymized data;
receiving selective anonymized data;
de-anonymizing the received anonymized data; and
returning the de-anonymized data that matches the search term as a response to the search request.
3. The method of claim 1 , further including:
providing a search ID field marker to indicate the beginning of the selected portion of the anonymized data; and
transmitting the search ID field marker along with the anonymized data to the destination computing device.
4. An anonymization system to anonymize data transmitted to a destination computing device, comprising:
one or more processor devices;
an anonymization strategy module to store anonymization strategy for data anonymization;
a logic to receive data to be transmitted to the destination computing device, from a user computer, the data including a plurality of characters;
an anonymization module to anonymize the data based on an anonymization strategy;
select a portion of the anonymized data as a search ID;
store in a data store, a cross reference between a search key indicative of a portion of the received data and the corresponding search ID such that the search ID can be retrieved that corresponds to the search key which matches a search term in a search request for the anonymized data; and
transmit anonymized data to the destination computing device over a network and in response to receiving the search request, selective anonymized data can this be obtained based on the retrieved search ID that matches with the portion of the anonymized data such that the de-anonymized data can be returned as a response to the search request.
5. The system of claim 4 , further configured to:
receive a request to search the anonymized data stored at the destination computing device, using a search term;
retrieve search ID that corresponds to the search key matching the search term;
send a search request to the destination computing device to retrieve selective anonymized data wherein the search ID matches with the portion of the anonymized data;
receive selective anonymized data;
de-anonymize the received anonymized data; and
return the de-anonymized data that matches the search term as a response to the search request.
6. The system of claim 4 , further configured to:
provide a search ID field marker to indicate the beginning of the selected portion of the anonymized data; and
transmit the search ID field marker along with the anonymized data to the destination computing device.
