Abstract
A computing system includes a processor; and a memory communicatively coupled to the processor. The processor is configured to: generate a challenge response test image comprising a plurality of well-formed construct elements forming a well-formed construct and a plurality of random construct elements; and provide a plurality of masks to be placed over the image, one of the number of masks configured to reveal the well-formed construct elements when placed over the image.
Claims16
A computing system comprising:
- a processor;
- and
- a memory communicatively coupled to said processor;
- in which said processor is configured to:
- generate a challenge response test image comprising a plurality of well-formed construct elements forming a well-formed construct and a plurality of random construct elements;
- and
- provide a plurality of masks to be placed over said image, one of said number of masks configured to reveal said well-formed construct elements when placed over said image;
- in which said well-formed construct elements comprise words or images of a properly formed sentence and said well-formed construct comprises said sentence.
A computer program product for providing a challenge response test, said computer program product comprising:
- a computer readable storage device having computer readable code embodied therewith, said computer readable program code comprising:
- computer readable program code configured to generate a challenge response test image comprising a plurality of well-formed construct elements forming a well-formed construct and a plurality of random construct elements;
- and
- computer readable program code configured to provide a plurality of masks to be placed over said image, one of said number of masks configured to reveal said well-formed construct elements when placed over said image;
- in which said well-formed construct elements comprise words or images of a properly formed sentence and said well-formed construct comprises said sentence.
