Combining multiple modes is sometimes referred to as multi-modal authentication.

Continuous authentication utilizes physiological biometrics pattern recognition, behavioral biometrics pattern recognition, and context-aware authentication modes, sometimes in combination. It passively re-authenticates users without notifying the user or requiring any user attention, and it locks the system automatically in case the user is inactive or when it observes irregularities or anomalous behaviors. The latter is a seamless and transparent form of authentication that runs in the background without notifying the user or requiring any user attention.Ĭontinuous authentication (CA) offers advantages with regard to usability and security.

The former requires explicit user attention or user action, such as entering a password or pin or putting a finger on the finger print scanner. User authentication can be conducted actively or passively.

This issue could be mitigated by security mechanisms that continuously re-authenticate the user during the session. In the case of service/cloud-side authentication, the user provides some authentication credentials to the server, which then determines whether the user is authentic or not and on that basis grants the user access to the service.Ī potential problem about session-oriented approaches is that if the user leaves the computer or the device for some time, a malicious user accessing the device in the meantime is not prevented from using it or any services that the user is logged onto. In the case of device-side authentication, the session normally lasts as long as the user is using the device actively, and after that, it locks automatically. In a “traditional” setting, the user authenticates himself at the beginning of a session. Many mobile devices are using cloud-based services for data processing and storage, which facilitate access to multiple services and also provide easy backup to data. High-performance computational resources and on-demand availability enable users and companies to leverage cloud-based services. By means of his user credentials, the user proves his authenticity to the cloud (authentication server), which performs the user authentication and grants the user access to the service if the authentication succeeded. (2) The user will authenticate himself towards a cloud service. Device-side authentication is performed entirely on the device. In general, user authentication can be performed on a device or a server-side: (1) The user will authenticate himself towards the mobile device. A disadvantage about physiological biometrics is that physiological features are static, which can be reproduced by an adversary. These approaches attempt to improve the usability over conventional authentication approaches. Nowadays, physiological biometric-based approaches are widely adopted in smart devices that use face recognition and fingerprints recognition, which are examples of what we refer to as authentication modes or simply “modes”.

Weak passwords can be broken easily and strong passwords are not memorable. This happens due to poor implementation of authentication mechanisms. According to a report, cyberattacks are happening every year, and accounts are being compromised every second. Authentication can be characterized by different factors such as knowledge-based authentication (PIN, password), possession-based (devices, smartcards, etc.), physiological-based (such as fingerprint, iris, voice, face), behavioral-based (such as keystroke dynamics, touch dynamics, motion dynamics, etc), and context-aware factors (such as physical location, IP-addresses, device-specific data, browsing history, etc.). Authentication ensures that the given entity is one it claims to be. We interact with devices in the form of smart-phones, cars, sensors, Internet of Things (IoT), and other devices. We are dependent on computing technology to store and process our personal data.
