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. The data includes a plurality of fields. One or more fields are selectively extracted. A hash using the extracted fields is computed. The computed hash is stored. Anonymization of the data is performed, using an anonymization module. Anonymized data is transmitted to the destination computing device over a network.
