Recently most of the financial audit and business registration rely on computer systems, secret and sensitive business information like business spending and receipts, business partners and outgoings/incomings are susceptible to leak to third parties. Existing taxreturn and Registrar of Companies (ROC) registration routes via auditing bureaus have channels for exit approaches where secret information leaks and can be viewed by third-party abusers by lenders, share dealers and insurers. To counteract this ultimate test of privacy, our proposed approach presents a Secure Anonymized Auditing Framework (SAAF) that ensures privacy-preserving processing of financial data. In our proposed methodology financial data and firm identities are private but anonymized and encrypted identifiers are made public to audit institutions. The right to complete decryption is in the hands of the firm and rightful government agencies, not in the hands of criminal entities that are able to accumulate data, therefore narrowing the range of misuse. Our proposed approach enhances data security and compliance with regulation, enhancing confidence in electronic financial systems. In our Proposed Privacy-Preserving approach of Confidential Identity Mapping (CIM), firm identities are encrypted during data transactions with audit agency, but accessible privileges given only to authorized stakeholders for decrypted data of firms. The approach merges secure encryption practices with granting role-based privileged decryption in an attempt to avoid information exposure and maintain confidentiality in auditing and financial reporting processes.
