Latest Patents

Alsvig’s listed patent, “Unlocking Electronic Devices with Touchscreen Input Gestures,” describes a way to unlock a device using gestures on its touchscreen. While the device is locked, the screen displays lines that divide it into input regions. The device detects a gesture, identifies the region where the gesture began, and combines that region’s base number with a value associated with the gesture to calculate a password digit. It then compares the resulting sequence of digits with the stored password and unlocks the device if they match.

Career Highlights

Alsvig’s patent work reflects an approach to device security that combines touchscreen gestures with numerical password entry. The method uses the gesture’s starting location as part of the calculation, linking screen regions and user input to the unlocking process.

Collaborations

Alsvig’s listed coworkers include Jian Zhong Li and Martin A. Tiernan. His work is associated with International Business Machines Corporation.

Conclusion

John E. Alsvig’s patent work highlights a touchscreen security method that turns gestures and their starting regions into password digits for unlocking electronic devices.
