Verification of user identities is an important aspect of computer and network security. In some instances, a first user may attempt to engage with a second user via a web application, mobile phone app, or other software without necessary knowing that the identity of a second user is accurate. The computer security problem of identity verification may be particularly acute when the only contact information is an email address, phone number, or other electronic identifier that can potentially change ownership (e.g. a person may get a new phone number, someone might purchase an Internet domain and thus change ownership of an email address, etc.) This disclosure and claims relate to techniques that allow for enhanced security by verifying an identity of a user via specific prompts and interactions provided via software. Particular credentials may be required in order to verify user identity, including biometrics and other specific required responses.
