A CAPTCHA is a test to tell wether a user is human or a computer. They mostly come in the form of distorted letters at the end of comments on news sites, blogs or in registration forms. Their main function is to prevent abuse from “bots” or automated programs written to generate spam. Civil Rights CAPTCHA is unique in its approach at separating humans from bots, namely by using human emotion. This enables a simpler and more effective way of keeping sites spam free as well as taking a stand for human rights.
Let’s look first at how an ABT is made. In the interconnected, automated, all-weather world of modern aviation, tags must be resistant to cold, heat, sunlight, ice, oil, and especially moisture. Tags also can’t tear—and crucially, if they’re nicked, they must not tear further—as the bag lurches through mechanized airport baggage systems. And the tag must be flexible, inexpensive, and disposable. Plain old paper can’t begin to meet all these requirements. The winning combination is what IATA’s spokesperson described as a “complex composite” of silicon and plastic; the only paper in it is in the adhesive backing.
