Secure Mobile File Sharing via P2P Link and Permission Verification

The patent introduces an intermediary permission checking mechanism that sits between the file sharing action and the actual file transfer. When a user attempts to share a file via e-mail or other channels, the system intercepts the request, checks the recipient's permissions against corporate policy, and either allows or blocks the transfer accordingly. This mediator ensures security compliance without completely preventing convenient file sharing methods.

The system implements feedback by continuously monitoring file sharing attempts and providing real-time permission verification. When a file sharing action occurs, the system checks permissions and provides immediate feedback on whether the transfer is authorized. This feedback loop ensures that corporate security policies are enforced dynamically based on user credentials and file classification levels.

The patent applies preliminary action by implementing permission checks before files are transferred to or from personal devices. The system pre-authenticates user credentials, pre-classifies files according to corporate security policies, and pre-determines whether a given device-user combination is authorized to access specific files. This preliminary security verification occurs before the actual file transfer, allowing personal device usage while maintaining control.

The system segments security control by creating separate permission layers for different devices, users, and file types. Instead of treating all personal devices uniformly, the system divides permission checking into granular segments based on user credentials, device identity, file classification, and corporate policy rules. This segmented approach allows selective authorization, enabling legitimate personal device usage while blocking unauthorized access.
