Patent ID: 7290136

Claim:
A method for providing tiered, multi-stage intelligent detection and enforcement of security on a pervasive device, the method comprising the steps of: monitoring the pervasive device for the presence of a security identifier, comprising: periodically detecting the presence of the identification signal on a predetermined time interval; and measuring the elapsed time from the last detection of the identifier signal; and establishing a current security level chosen from a plurality of security levels for the pervasive device based on the presence of the security identifier; comprising: comparing the elapsed time from the last detection of the identification signal to one or more predefined threshold levels; determining the current security level for the pervasive device based upon where the elapsed time falls within the one or more predefined threshold levels, wherein the pervasive device is at a low risk security level if the elapsed time from the last detection of the identification signal is less than a first threshold value, and the pervasive device is at an elevated risk security level if the elapsed time from the last detection of the identification signal is greater than the first threshold value; and adjusting the amount of identification information required to be provided by a user to access the device based upon the current security level; wherein if the pervasive device is at the elevated risk security level, the detection of the identification signal returns the device to the low risk security level, and wherein a user of the pervasive device is required to enter a user identifier to access sensitive user information within the pervasive device when the pervasive device is at the elevated risk security level and a failure to successfully enter the user identifier when the pervasive device is at the elevated risk security level causes the device to assume an even higher risk security level, wherein the even higher risk security level requires the user to enter a complex user identifier in order to access sensitive user information within the pervasive device, and if the pervasive device is at the even higher risk security level, the detection of the identification signal returns the device to the low risk security level, wherein a failure to successfully provide the complex user identifier to the pervasive device causes the pervasive device to enter an exploit security level.
