摘要
Techniques are described for passive authentication based at least partly on collected voice data of a user. During a speech interaction between a user and a personal assistant (PA) device, the user's speech may be analyzed to authenticate the user. The authentication of the user may be a passive authentication, in which the user is not explicitly asked to provide authenticating credentials. Instead, the speech data of the user is collected during the user's interactions with the PA device, and the collected speech data is compared to a previously developed model of the user's speech. The user is successfully authenticated based on determining that there is sufficient correspondence between the collected speech data and the model of the user's speech. After the user is authenticated passively during the conversation, they may be able to access sensitive data or services that may not be otherwise inaccessible without authentication.
說明書
Based on a successful authentication of the user 102, the analysis device(s) 120 may communicate response data 130 to the PA device 104. In some implementations, the response data 130 may indicate whether the user 102 has been authenticated. In some instances, the response data 130 can include sensitive information that the user 102 has requested. Based on a successful passive authentication of the user 102 based on the user's speech data, the request for sensitive information may be approved and the sensitive data can be sent to the PA device 104 to be output, through the CUI 108, to the user 102.
