Validating internet information

Input validation is performed to ensure only properly formed data is entering the workflow in an information system, preventing malformed data from persisting in the database and triggering malfunction of various downstream components.

Input validation should happen as early as possible in the data flow, preferably as soon as the data is received from the external party.

With so much content and so little oversite, determining which information is reliable can be a daunting task.

There are over 600 million active websites in the world, many of which are protected by free speech and anti-censorship laws.

Website owners can print anything they want, true or not, without worrying about the consequences.

Think about the magazine section in your local grocery store.

If you reach out with your eyes closed and grab the first magazine you touch, you are about as likely to get a supermarket tabloid as you are a respected journal (actually more likely, since many respected journals don't fare well in grocery stores).

Corporations can make websites to promote their products, and political activists can publish websites to promote their cause.
