Method for securing synthetic video conference feeds

A method comprising:

• during a setup period:
• accessing a target image depicting a face of a first user;
• generating a first face model based on a target set of facial features detected in the target image;
• and
• linking the first face model to a target set of facial biometric values of the first user;
• and
• during an operating period succeeding the setup period:
• accessing a first video feed;
• and
• selecting a first frame, recorded at a first time, from the first video feed;
• deriving characteristics of a first set of facial features detected in the first frame;
• extracting a first set of facial biometric values from the first frame;
• and
• in response to alignment between the target set of facial biometric values and the first set of facial biometric values, at the first device, generating a first synthetic face image based on characteristics of the first set of facial features, the first face model, and a synthetic face generator;
• and
• transmitting the first synthetic face image to a device at approximately the first time.
