Privacy enabled inter-bank settlements and auditing of fund transfer has been addressed using private and shared databases in the blockchain. These are resource inefficient and incur additional overhead on banks to maintain the extra databases. These also pose some security concerns. A method and system disclosed leverages blockchain and Conditional Homomorphic Proxy Re-encryption (CH-PRE) to preserve the privacy of the customer information (balances and transfer amounts) and enables faster auditable settlement between the banks in the presence of governing body. Perform computations on encrypted data (customer balances and transfer amounts) to audit and validate the transaction data without revealing customer information such as balances. As customer balances and transfer amounts are stored in encrypted format, an attacker who is able to gain access to this encrypted data, will not be able to read the customer balances and transfer amounts, as the attacker does not possess bank's private key.
