Password entry for double sided multi-touch display

A system, comprising:

• a processor in circuit communication with a computer readable memory and a computer readable storage medium;
• wherein the processor, when executing program instructions stored on the computer-readable storage medium via the computer readable memory:
• defines a first contact pattern as a pattern of touchscreen contact inputs generated from contact of a first contact element on a first touchscreen of a programmable device dual-touchscreen assembly that has a second touchscreen located back-to-back with the first touchscreen;
• defines a second contact pattern as a pattern of touchscreen contact inputs that are generated from contact of a second contact element on the second touchscreen contemporaneously with the pattern of touchscreen contact inputs generated from contact of a first contact element on a first touchscreen, wherein the first and second touchscreens are transparent and enable a viewer to see through each of the first and second touchscreens in the dual-touchscreen assembly;
• and
• defines a composite password pattern by mapping the location of the first pattern on the first screen relative to the location of the second pattern on the second screen, wherein recognizing a successful entry of the composite password pattern requires an entry of the first pattern on one of the first and second touchscreens contemporaneously with an entry of the second pattern on another of the first and second touchscreens in an alignment that is compliant with the composite password mapping.

A computer program product for password definition and recognition in programmable devices with back-to-back touchscreens, the computer program product comprising:

• a computer readable storage medium having computer readable program code embodied therewith, the computer readable program code comprising instructions that, when executed by a processor, cause the processor to:
• define a first contact pattern as a pattern of touchscreen contact inputs generated from contact of a first contact element on a first touchscreen of a programmable device dual-touchscreen assembly that has a second touchscreen located back-to-back with the first touchscreen;
• define a second contact pattern as a pattern of touchscreen contact inputs that are generated from contact of a second contact element on the second touchscreen contemporaneously with the pattern of touchscreen contact inputs generated from contact of a first contact element on a first touchscreen, wherein the first and second touchscreens are transparent and enable a viewer to see through each of the first and second touchscreens in the dual-touchscreen assembly;
• and
• define a composite password pattern by mapping the location of the first pattern on the first screen relative to the location of the second pattern on the second screen, wherein recognizing a successful entry of the composite password pattern requires an entry of the first pattern on one of the first and second touchscreens contemporaneously with an entry of the second pattern on another of the first and second touchscreens in an alignment that is compliant with the composite password mapping.
