People depending on mobile apps to manage their payments and do their banking transactions, made it essential to protect applications operations such as session data, user details, credit card info… etc. It became more challenging to securely store data locally on a device.

ELS – Encrypted Local storage is a state-of-the-art security feature that provides app developers with the ability to store app secrets, such as session tokens, personally identifiable information, API keys and more, locally on the end-user device in a secure and encrypted manner, even if the device integrity is broken (e.g. rooted or jailbroken).

The feature does not rely on device functionality (such as keychains) to provide secure storage of sensitive data and is fully self-contained. The encryption keys used are never stored on the device, or added in the static code of the app, but are dynamically generated on the device protected by The Guardian’s Whitebox backed solution. This further ensures that the data is device-bound, and cannot be copied to a different device.
