Abstract: We present a new CAPTCHA which is based on identifying an image’s upright orientation. This task requires analysis of the often complex contents of an image, a task which humans usually perform well and machines generally do not. Given a large repository of images, such as those from a web search result, we use a suite of automated orientation detectors to prune those images that can be automatically set upright easily. We then apply a social feedback mechanism to verify that the remaining images have a human-recognizable upright orientation. The main advantages of our CAPTCHA technique over the traditional text recognition techniques are that it is language-independent, does not require text-entry (e.g. for a mobile device), and employs another domain for CAPTCHA generation beyond character obfuscation. This CAPTCHA lends itself to rapid implementation and has an almost limitless supply of images. We conducted extensive experiments to measure the viability of this technique.
"Software that can solve any text-based CAPTCHA will be as much a milestone for artificial intelligence as it will be a problem for online security."
"With the advent of general-purpose GPUs, the Cell BE processor, and the upcoming Larrabee chip from Intel, data parallel computing has become the hot new supermodel in HPC. And even though NVIDIA took the lead in this area with its CUDA development environment, Intel has been busy working on Ct, its own data parallel computing environment." ...
"Ct is a high-level software environment that applies data parallelism to current multicore and future manycore architectures. ... Ct allows scientists and mathematicians to construct algorithms in familiar-looking algebraic notation. Best of all, the programmer does not need to be concerned with mapping data structures and operations onto cores or vector units; Ct's high level of abstraction performs the mappings transparently. 'The two big challenges in parallel computing is getting it correct and getting it to scale, and Ct directly takes aim at both' ..."

Oh, and I changed the title too, for good measure (not to mention alliteration).
