Patent attributes
A heightened level of security is provided in a computing platform by monitoring usage of applications and/or services residing on or accessible to a computing platform to determine abnormal usage patterns. In response to determining an abnormal pattern of usage, the user is required to provide biometric data, such as voice data, facial feature data, fingerprint data or the like, as a means of authenticating the user. The abnormal pattern of usage may be determined dynamically by comparing current usage patterns to known user baseline usage patterns. Alternatively, the abnormal pattern of usage is predefined, such as the resetting of passwords in a predefined number of applications and/or services over a predefined period of time.
