Mobile devices are more than just a way of communicating. Mobile devices are used for email, social media, gaming, banking, photos. Mobile devices are used for both business and personal use, and today mobile phones are used more widely than personal computers. Mobile ID can replace plastic cards, badges, and ID cards and allow users to complete identification, authentication, payments, and even digital signatures. Previous methods of physical personal identification can be stored or accessed in the mobile device, eliminating the need to carry a wallet, or wait for replacement cards to come in the mail.
As the ubiquity of mobile devices changes how people engage in day-to-day activities, it also increases security concerns about the information stored or accessed by these devices. To be trusted, Mobile ID schemes call for the enforcement of privacy and security requirements.
