SECURITY AND PROTECTION DEVICE AND METHODOLOGY

摘要

A mobile device includes a security device. The security device determines whether the mobile device is inside or outside security zones defined around a device being carried around by a user and an access point disposed at or near a place where the user regularly visit by detecting presence or absence of the wireless connection therewith. The device further determines whether or not there is an ongoing scheduled event and whether the mobile device is at or near an event location. The device further assesses a risk level of an environment where the mobile device is currently disposed based on determination results, and executes one of preset security action controls in response to the risk level determined to allow the mobile device to perform a security action to alert the user.

主权项

1. A security device to protect a mobile device against theft or misplacement, the security device comprising:
memory configured to store
a friendly device table that includes a plurality of wireless-enabled devices, wherein each wireless-enabled device serves as a reference point for the mobile device and has a predetermined secure zone,an event location table that includes a plurality of event locations, wherein each event location is assigned at least one wireless-enabled device that communicates with the mobile device, and circuitry configured to:
compute a first risk level based on a first location of the mobile device with respect to the predetermined secure zones of the wireless-enabled devices;calculate a second risk level based on proximity of the mobile device with respect to at least one event location of the plurality of event locations,compute a third risk level based on information gathered from a plurality of sensors disposed on the mobile device,compute an overall risk level based on the first risk level, the second risk level, the third risk level, and a predetermined risk-assessment table,formulate a shared risk network of the mobile device based on communication of the mobile device with a plurality of other mobile devices,calculate a change in the overall risk level based on a change in the computed overall risk level of the mobile device and the formulated shared risk network, andperform a predetermined security action based on the calculated change in the overall risk level.
