Abstract
Aspects of the disclosed technology include a method including identifying, by a computer device, a message; encoding, by the computer device, the message; receiving, by the computer device, a video of a user reciting the encoded message; and providing, by the computer device, the message and the video for verification an authenticity of the message.
Claims20
A method comprising:
- identifying, by a computer device, a message, the message comprising a public encryption key;
- encoding, by the computer device, the message;
- receiving, by the computer device, a video of a user reciting the encoded message;
- and
- providing, by the computer device, the message and the video for verification an authenticity of the message.

A method comprising:
- accessing, by a computer device, a public ledger to identify a first message and a second message, the first message including a first hash value, and the second message including a video and a public encryption key;
- hashing, by the computer device, the video and the public encryption key from the second message to create a second hash value;
- comparing, by the computer device, the first hash value and the second hash value;
- encoding, by the computer device, the public encryption key to a speakable phrase;
- determining that the video includes a speaker reciting the speakable phrase;
- and
- verifying, by the computer device and in response to the comparing indicating that the first hash value equals the second hash value and the determining that the video includes the speaker reciting the speakable phrase, the public encryption key.
4 more elements
A method comprising:
- initiating, by a computer device, a telephone communication to an external device;
- encoding, by the computer device and using a public encryption key, a shared secret shared with the external device, the encode shared secret comprising a plurality of numerical values;
- converting the encoded shared secret to a series of dial-tones corresponding to the plurality of numerical values;
- and
- transmitting, to the external device and using the telephone communication, the series of dial-tones.
2 more elements
A method comprising:
- identifying, by a computer device, a message;
- encoding, by the computer device, the message by:
- converting the message to a plurality of numerical values,
- extracting, from at least one collection of speakable words, a plurality of speakable words corresponding to the plurality of numerical values, and
- encoding the message as a multi-word phrase of the plurality of the extracted speakable words;
- receiving, by the computer device, a video of a user reciting the encoded message;
- and
- providing, by the computer device, the message and the video for verification an authenticity of the message.
