E-Wallet App

I focus on ensuring secure communication and data protection by integrating banking and wallet systems. I implement strong encryption protocols like AES for encrypting sensitive data such as user credentials, transactions, and balances. For secure communication, I use SSL/TLS to encrypt data transmission between the mobile app and the server. Additionally, I integrate secure authentication methods, including two-factor authentication (2FA) and biometric login (fingerprint/face recognition), to protect user access. To ensure compliance with regulatory standards such as PCI-DSS and GDPR, I use secure key storage solutions like iOS’s Keychain and Android’s Keystore for cryptographic key management. I also ensure tokenization to replace sensitive payment data with unique identifiers, reducing the risk of data breaches. Throughout, I follow best practices for input validation, secure session management, and anomaly detection to safeguard both the app and user data from malicious threats.
