Encryption synchronization method

This invention outlines a secure login and data synchronization method. It works by having a user create a unique "encrypted mark" with their own secret key. Crucially, the system keeps this encryption key only on the user's device, with the server merely knowing where to ask for it and generating a script to retrieve it, ensuring no sensitive data ever leaves the user's control.

Why it matters: The filing predates the widespread adoption of zero-trust security models and the significant enhancement of client-side cryptographic capabilities. Modern browsers and operating systems now offer more robust secure local storage and script execution environments, making this client-centric key management approach more practical and aligned with current privacy regulations.
