Mobile device having increased security that is less obtrusive

A method to provide security for a mobile device comprising:

• monitoring operation of the mobile device;
• performing a monitor process to implement a plurality of monitor functions;
• and
• wherein the monitor process is implemented after a user has entered a valid passcode;
• wherein at least one of the plurality of monitor functions is based upon pressure sensor readings from a pressure sensor;
• performing an authentication process to compare the plurality of monitor functions to a time period to determine an authentication value;
• wherein each monitor function is associated with a pre-determined weight;
• wherein if the authentication value exceeds a threshold,
• implementing a lock screen on a display device of the mobile device, and
• requiring the user to enter the valid passcode through a user interface of the mobile device for authentication;
• and
• wherein if the threshold is not exceeded, the user is not required to enter the valid passcode.

A mobile device comprising:

• means for monitoring operation of the mobile device;
• means for pressure sensing;
• means for performing a monitor process to implement a plurality of monitor functions;
• and
• wherein the monitor process is implemented after a user has entered a valid passcode;
• and
• wherein at least one of the plurality of monitor functions is based upon pressure sensor readings from the means for pressure sensing;
• means for performing an authentication process to compare the plurality of monitor functions to a time period to determine an authentication value;
• wherein each monitor function is associated with a pre-determined weight;
• wherein if the authentication value exceeds a threshold,
• means for implementing a lock screen on a display device of the mobile device, and
• means for requiring the user to enter the valid passcode through a user interface of the mobile device for authentication;
• and
• wherein if the threshold is not exceeded, the user is not required to enter the valid passcode.

A computer program product comprising:

• a non-transitory computer-readable medium comprising code for:
• monitoring operation of the mobile device;
• performing a monitor process to implement a plurality of monitor functions;
• and
• wherein the monitor process is implemented after a user has entered a valid passcode;
• and
• wherein at least one of the plurality of monitor functions is based upon pressure sensor readings from a pressure sensor;
• performing an authentication process to compare the plurality of monitor functions to a time period to determine an authentication value;
• wherein each monitor function is associated with a pre-determined weight;
• wherein if the authentication value exceeds a threshold,
• implementing a lock screen on a display device of the mobile device, and
• requiring the user to enter the valid passcode through a user interface of the mobile device for authentication;
• and
• wherein if the threshold is not exceeded, a the user is not required to enter the valid passcode.
