Techniques for implementing voice-based liveness verification are provided. In one embodiment, a computing device can present a series of challenge prompts to a user being authenticated, where each challenge prompt corresponds to a request to utter a liveness passphrase that is randomly selected from a set of liveness passphrases that have been previously enrolled by an enrolled user of the computing device. The computing device can then receive utterances from the user in response to the series of challenge prompts and, if each utterance matches its corresponding enrolled liveness passphrase, can conclude that the user is a live subject.

Voice-based liveness verification

A non-transitory processor-readable medium stores code representing instructions to be executed by a processor. The code causes the processor to receive a request from a user of a client device to initiate a speech recognition engine for a web page displayed at the client device. In response to the request, the code causes the processor to (1) download, from a server associated with a first party, the speech recognition engine into the client device; and then (2) analyze, using the speech recognition engine, content of the web page including text in an identified language to produce analyzed content based on the identified language, where the content of the web page is received from a server associated with a second party. The code further causes the processor to send a signal to cause the client device to present the analyzed content to the user at the client device.
