Embodiment Construction

[0026] Some configurations of the systems and methods disclosed herein provide password strength assessments and recommendations for voice-based biometric authentication. When using voice for authentication purposes, the user may want to set the password to be spoken. However, it may be difficult to know whether the password will be unique enough in terms of voice timbre that no one else can break the system when the same password happens to be spoken. It would be even better if the spoken password contained the user's own biometric difference from an arbitrary set password. If additional means are available, they can be used to enforce security as appropriate.

[0027] The systems and methods disclosed herein can provide a way to assess the strength of "uniqueness" so that a user can choose a sufficiently unique password. In some configurations, the systems and methods disclosed herein may suggest some candidates using utterances that preserve the user's enhanced uniqueness...

Abstract

The present invention describes a method for evaluating the strength of an audio password by an electronic device. The method includes obtaining audio signals captured by one or more microphones. The audio signal includes an audio password. The method also includes evaluating the strength of the audio password based on measuring one or more unique characteristics of the audio signal. The method further includes informing a user that the audio password is weak based on the evaluation of the strength of the audio password.

Description

technical field [0001] The present invention generally relates to electronic devices. More specifically, the present invention relates to systems and methods for evaluating the strength of audio commands. Background technique [0002] In recent decades, the use of electronic devices has become widespread. In particular, advances in electronics technology have reduced the cost of increasingly complex and useful electronic devices. Reduced costs and consumer demand have dramatically increased the use of electronic devices, making them ubiquitous in modern society. As the use of electronic devices has spread, there has been a need for new and improved features of electronic devices. More specifically, electronic devices are often sought to perform new functions and / or perform functions faster, more efficiently, or with higher quality. [0003] Some electronic devices (eg, cellular phones, smart phones, audio recorders, camcorders, computers, etc.) utilize audio signals. Th...
