Binding a data transaction to a person's identity using biometrics

A computer-implemented method comprising:

• receiving, at a first device associated with a user, transaction data including a data representation of information associated with a transaction between the first device and a second device;
• receiving authentication data associated with the transaction data, the authentication data including captured audio and/or video data of a computed data representation as inputted by the user, the first data representation computed from the information associated with the transaction using a defined algorithm, wherein the algorithm results in a different data representation when the information changes, and wherein the first computed data representation is implanted into the captured audio and/or video data;
• and
• verifying the transaction data received by the second device, by:
• computing a second data representation from the received transaction data using the defined algorithm;
• and
• comparing the computed second data representation to the first computed data representation implanted into the audio and/or video data of the received authentication data to identify a match;
• wherein an identity of the user associated with the first device is verified from the audio and/or video data of the received authentication data.

A system comprising one or more hardware computer processors configured to:

• generate, by the one or more hardware computer processors, transaction data including information associated with a transaction between a first device and a second device, the first device associated with a user;
• generate, by the one or more hardware computer processors, authentication data associated with the transaction data, by:
• i) computing a first data representation of the information associated with the transaction using a defined algorithm, wherein the algorithm results in a different data representation when the information changes;
• ii) prompting the user to record inputting of the computed first data representation;
• and
• iii) capturing audio and/or video data of the computed first data representation as inputted by the user in response to the prompting, wherein the computed first data representation is implanted into the captured audio and/or video;
• data
• transmitting the transaction data and the associated authentication data to the second device;
• verify the transaction data received by the second device, by:
• i) computing a second data representation from the received transaction data using the defined algorithm;
• and
• ii) comparing the computed second data representation to the first computed data representation implanted into the audio and/or video data of the received authentication data to identify a match;
• wherein an identity of the user associated with the first device is verified from the audio and/or video data of the received authentication data.

A non-transitive computer-readable storage medium storing computer-executable instructions to perform a method of:

• generating transaction data associated with a transaction between a first device and a second device associated with a user;
• generating authentication data providing an irrevocable binding of the transaction data to at least one biometric characteristic of the user, by:
• i) computing a first data representation of the information associated with the transaction using a defined algorithm, wherein the algorithm results in a different data representation when the information changes;
• ii) prompting the user to record inputting of the computed first data representation;
• and
• iii) capturing audio and/or video data of the computed first data representation as inputted by the user in response to the prompting, wherein the computed first data representation is implanted into the captured audio and/or video data;
• transmitting the transaction data and the associated authentication data to the server;
• and
• verifying the transaction data received by the second device, by:
• i) computing a second data representation from the received transaction data using the defined algorithm;
• and
• ii) comparing the computed second data representation to the first computed data representation implanted into the audio and/or video data of the received authentication data to identify a match;
• wherein an identity of the user associated with the first device is verified from the audio and/or video data of the received authentication data.
