End-to-End Encryption (E2EE):
Use E2EE to ensure that data is encrypted on the user's device and only decrypted on the
recipient's device. This prevents intermediaries (like app servers) from accessing sensitive
information.
Tokenization:
Instead of storing sensitive data (like credit card numbers) directly, use tokenization. The app
stores a unique token that represents the data, while the actual data resides in a secure vault. This
minimizes risks if there's a breach.
Multi-factor Authentication (MFA):
Require users to provide multiple forms of verification (e.g., password + OTP sent to their
phone) before conducting sensitive transactions.
Regular Security Audits:
Conduct regular security assessments and penetration tests to identify and fix vulnerabilities
proactively.
Data Minimization:
Collect only the necessary data for transactions and ensure any stored data is encrypted and
securely managed.
