A location-based service system and method, which allows a location-based service server connected with a communication device and a cloud data server to perform registration authorization procedures and service authorization procedures using an international mobile subscriber identity of the communication device that cannot be easily modified or forged in the registration and service modes, so that a user may obtain a specific location-based service result via the communication device, and this distributed authentication technique reduces the risk of data theft while increasing the flexibility and convenience in obtaining services.

A stackable filesystem architecture that curtails data theft and ensures file integrity protection. In this architecture, processes are grouped into ranked filesystem views, or “security domains.” Preferably, an order theory algorithm is utilized to determine a proper domain in which an application is run. In particular, a root domain provides a single view of the filesystem enabling transparent filesystem operations. Each security domain transparently creates multiple levels of stacking to protect the base filesystem, and to monitor file accesses without incurring significant performance overhead. By combining its layered architecture with view separation via security domains, the filesystem maintains data integrity and confidentiality.

The embodiment of the invention discloses a data migration method and a mobile terminal. The data migration method includes that a first terminal displays a two-dimensional code on a display interface, and the two-dimensional code is used for a second terminal to scan to acquire a hotspot identifier of a wireless hotspot created by the first terminal and password information corresponding to the hotspot identifier, and to establish a communication connection with the first terminal based on the hotspot identifier and the password information; the first terminal detects whether a trigger condition for triggering the first terminal to disconnect a public network is received; the first terminal disconnects the public network when the trigger condition is detected; and the first terminal transmits the data to be migrated to the second terminal based on the communication connection established with the second terminal so that the second terminal receives and stores the data to be migrated. The embodiment of the invention helps avoid the hidden danger of data theft caused by accessing the mobile data network or a wi-fi network, thereby further improving the security of data migration of the mobile terminal.

A decoy filesystem that curtails data theft and ensures file integrity protection through deception is described. To protect a base filesystem, the approach herein involves transparently creating multiple levels of stacking to enable various protection features, namely, monitoring file accesses, hiding and redacting sensitive files with baits, and injecting decoys onto fake system views that are purveyed to untrusted subjects, all while maintaining a pristine state to legitimate processes. In one implementation, a kernel hot-patch is used to seamlessly integrate the new filesystem module into live and existing environments.
