Identity theft and the loss or exposure of data and intellectual property is a growing cyber security concern. Symantec put the costs of cyber fraud in 2015 at $158 billion dollars.
Most people have multiple passwords, credit card numbers, PINs, usernames, bank account details, photos, documents and other information that they need to protect. It is getting increasingly more difficult to manage access while guarding both identity and data. Authentication–verifying that the user is who he/she claims to be – is key to all cyber security.
Today, there are three main methods of authentication: 1) something the user knows (such as a password/PIN), 2) something the user has (a security token or smart card), 3) something the user is (a physical characteristic, such as a fingerprint, called a biometric).
