The present disclosure relates to a method and system for two parties, such as a Customer Service Provider and a biller, to authenticate a mutual customer. The present invention uses a dynamic matching algorithm to check and match the customer information available from each party, without either party disclosing new information about the customer to the other. The method also comprises maintaining a set of canonical customer identification attributes to facilitate matching between entities based on sensitivity and stability of the attribute. The present disclosure provides a solution for authenticating customers by sharing the least sensitive information with each other to identify a customer. The method also comprises obtaining the information from customer in case there is no match. The system is also updated at the same time which makes the system adaptive. The information shared during the linking session is deleted.
