Actually, that's not a bad idea for a company to build off of...
Imagine, something to validate humanity, similar to captcha. The company has a steem account (They wouldn't need one though, even, probably.) and they use the api to monitor the chain. The verification app shows the image as usual, the input it, it posts under the app id on the chain, the company's monitoring bot picks up that the correct information has been posted to the chain, they are verified human! :)
