Security enhancements for pervasive devices
View Patent ↗A method, apparatus, and program product for tiered, multi-state intelligent detection and enforcement of security on a pervasive device is provided. The method/apparatus first monitors the pervasive device for the presence of a security identifier, then establishes a current security level chosen from a plurality of security levels for the pervasive device based on the presence of the security identifier.
1. A pervasive device security system having a multi-stage security feature, the pervasive device security system comprising:
a pervasive device containing sensitive data in a memory, the pervasive device including a receiver for receiving a security identification signal; and
an indicator device having a transmitter for transmitting the security identification signal, the indicator device typically positioned within broadcast proximity of the pervasive device.
2. The pervasive device security system of claim 1 , wherein the pervasive device further comprises:
a processor for measuring the elapsed time since the presence of the security identification signal has been last received, comparing the elapsed time from the last reception of the identification signal to one or more predefined threshold levels; and determining the current security level for the pervasive device based upon where elapsed time falls within the one or more predefined threshold levels.
3. The pervasive device security system of claim 2 , wherein the pervasive device further comprises:
a user interface which receives password input from a user of the pervasive device.
4. The pervasive device security system of claim 3 , wherein the pervasive device further comprises:
a security state indicator for displaying information about the current security level of the device.
5. A program product for providing access security to a pervasive device, the program product comprising:
executable code to detect the presence of an indicator device in proximity to the pervasive device and establish a security level chosen from a plurality of security levels for the pervasive device based on the presence of the indicator device, and a signal bearing media carrying said executable code.
6. The program product of claim 5 , wherein the executable code further includes code for periodically detecting the presence of an indicator device in proximity to the pervasive device on a predetermined interval, and measuring the elapsed time from the last detection of an indicator device.
7. The program product of claim 6 , wherein the executable code further includes code for comparing the elapsed time from the last detection of the indicator device to one or more predefined threshold levels, and determining the current security level for the pervasive device based upon where the elapsed time falls within the one or more predefined threshold levels.
8. The program product of claim 7 , wherein the executable code further includes code for adjusting the amount of identification information required to be provided by a user to access the device based upon the current security level.
