We modeled binary data corruption caused by a Brownian agent on a lattice. Our continuum model accurately predicts corrupted bit density and correlations, matching simulations and revealing log-normal distributions in 1D.

Area of Science:

  • Statistical Physics
  • Information Theory
  • Complex Systems

Background:

  • Binary data corruption is a critical issue in data transmission and storage.
  • Understanding the statistical properties of data corruption is essential for developing robust systems.
  • Brownian motion is a fundamental model for random processes.

Purpose of the Study:

  • To develop a theoretical model for binary data corruption induced by a Brownian agent.
  • To analytically calculate key statistical quantities of data corruption.
  • To compare theoretical predictions with numerical simulations.

Main Methods:

  • A continuum formulation of a lattice-based Brownian agent model.
  • Exact calculation of the density of corrupted bits (rho).

  • Calculation of the density-density correlation function and the probability distribution of rho in d=1.
  • Main Results:

    • The model accurately predicts the mean of rho and the density-density correlation function.
    • Theoretical results show excellent agreement with numerical simulations.
    • The probability distribution of rho in one dimension (d=1) is found to be log-normal.

    Conclusions:

    • The continuum model provides a powerful tool for analyzing binary data corruption.
    • The log-normal distribution in 1D suggests the system is governed by extreme fluctuations.
    • The study offers insights into the statistical behavior of random data corruption processes.
