Under a microscope, the malaria parasites can be detected in blood samples
But there aren't enough clinicians or clinics to meet demand
Low cost add-on optics for smart phones are enabling affordable, portable and internet-connected microscopes
‘Thick smear’ blood sample images can be collected on location
But the problem is the low certainty of a single untrained person studying the image and making an accurate diagnosis
'CAPTCHA's protect web services against automated bots trying to cheat their systems Worldwide we spend more than 500,000 hours every day processing CAPTCHAs to prove we're human More than 1000 are solved every SECOND
Google's reCAPTCHA service is arguably the most secure and robust freely-available CAPTCHA
but it's not just anti-bot protection..
Only one of the words is a known test word, the other is an image of an unknown word from a scanned book or article. If you pass the human test by getting the first word right, reCAPTCHA stores your answer for the unknown word

The blood testing hardware kit and app will enable smartphone owners to do their own high quality 'thick smear' tests to evaluate their friends and family for malaria.
The images must pass an simple built-in app quality assessment, and then can be uploaded to the mediCAPTCHA server.
The images are securely tagged with the patient's contact and location detils. Once the image passes through the mediCAPTCHA process, and reaches stastistical confidence thresholds, the patient is notified of the diagnosis and given advice for gaining treatment if needed.
Data is also provided to healthcare organisations to aid localised medical support strategies.
