| Description | In our paper, we analyze possibilities to generate true random data in mobile devices such as mobile phones or pocket computers. We show how to extract arguably true random data with a probability distribution $\epsilon=2^{-64}$ close to the uniform distribution in the trace distance. To postprocess the random data acquired from the camera we use a randomness extractor based on the Carter-Wegman universal${}_2$ families of hashing functions. We generate the data at the bit rate approximatively $36$ bits per second -- we used such a low bit rate only to allow statistical testing at a reasonable level of confidence. |
