Abstract
Various examples are directed to systems and methods for obscuring personal information in a sensor data stream. A system may apply an encoder model to the sensor data stream to generate a latent space representation of the sensor data stream. The system may also apply a noise-scaling parameter to the latent space representation of the sensor data stream and apply a decoder model to the latent space representation of the sensor data stream to generate an obscured data stream.
Claims20
A system for obscuring personal information in a sensor data stream, the system comprising:
- a computing device comprising at least one processor and an associated storage device, the at least one processor programmed to perform operations comprising:
- applying an encoder model to the sensor data stream to generate a latent space representation of the sensor data stream;
- applying a noise-scaling parameter to the latent space representation of the sensor data stream;
- and
- applying a decoder model to the latent space representation of the sensor data stream to generate an obscured data stream.
A method for obscuring personal information in a sensor data stream, the method comprising:
- applying, using at least one processor, an encoder model to the sensor data stream to generate a latent space representation of the sensor data stream;
- applying, using the at least one processor, a noise-scaling parameter to the latent space representation of the sensor data stream;
- and
- applying, using the at least one processor, a decoder model to the latent space representation of the sensor data stream to generate an obscured data stream.
A non-transitory machine-readable medium comprising instructions thereon that, when executed by at least one processor, causes the at least one processor to perform operations comprising:
- applying an encoder model to a sensor data stream to generate a latent space representation of the sensor data stream;
- applying a noise-scaling parameter to the latent space representation of the sensor data stream;
- and
- applying a decoder model to the latent space representation of the sensor data stream to generate an obscured data stream.
