Max Sound Corporation has been granted a patent for a voice-based biometric security system. First filed in early 2014, the system is entitled “Biometric audio security”, patent no. 9679427.
In a statement announcing the patent approva Max Sound CEO John Blaisure referred to the growing excitement over biometric security in general. But the company specializes in enhancing the audio quality of feeds from sources like Spotify and iTunes, describing its Max-D solution as “a proprietary audio process that restores lost compressed harmonics & brings high definition sound to digital media,” according to its website.
An abstract for the new patent, moreover, explains that it involves enhancing a voice input “by re-synthesizing the audio into a full range PCM wave,” which is then combined with a “hardware key with a set of audio frequency spikes” for user authentication. In other words, the system appears to be designed to combine a user’s voice with other audio signals to create a unique identifier that can then be used for authentication, evading the threat of spoofing through hack attacks that aim only to recreate the user’s voice.
Blaisure asserted that Max Sound has “already received inquiries from major potential partners to discuss licensing.”
