System and method for operating pseudorandom generators

A mobile computing device, comprising:

• at least one sensor;
• memory;
• and
• a processor coupled with the at least one sensor and the memory, the processor being configured to:
• collect raw sensor data from at least one sensor associated with the mobile computing device;
• select a subset of the raw sensor data based on:
• compression of the raw sensor data using a lossy compression technique to obtain a lossy compressed sensor data output;
• and
• selection, for inclusion in the subset, of one or more bits from a data bit stream associated with the at least one sensor that are not included in the lossy compressed sensor data output;
• apply a one-way cryptographic compression on the selected subset to obtain a compressed value;
• retrieve a first representation of accumulated entropy associated with one or more previously acquired raw sensor data sets for the at least one sensor;
• and
• generate an updated current representation of accumulated entropy based on combining the first representation and the compressed value.

A non-transitory, computer readable medium storing instructions that, when executed by a processor, cause the processor to:

• collect raw sensor data from at least one sensor associated with the mobile computing device;
• select a subset of the raw sensor data based on:
• compression of the raw sensor data using a lossy compression technique to obtain a lossy compressed sensor data output;
• and
• selection, for inclusion in the subset, of one or more bits from a data bit stream associated with the at least one sensor that are not included in the lossy compressed sensor data output;
• apply a one-way cryptographic compression on the selected subset to obtain a compressed value;
• retrieve a first representation of accumulated entropy associated with one or more previously acquired raw sensor data sets for the at least one sensor;
• and
• generate an updated current representation of accumulated entropy based on combining the first representation and the compressed value.
