# Fonts design-shapes processing of text information structures in process of non-invasive data acquisition

## TL;DR

This paper introduces two new computer fonts designed with specific line features to prevent electromagnetic infiltration, enhancing data protection during non-invasive data acquisition.

## Contribution

The article presents two novel fonts with unique line width features that hinder electromagnetic data extraction, improving security in non-invasive data collection.

## Key findings

- Fonts effectively prevent electromagnetic infiltration.
- Both fonts are suitable for everyday use.
- Design parameters are critical for security effectiveness.

## Abstract

Computer fonts can be one of solutions supporting a protection of information against electromagnetic penetration. This solution is called -Soft TEMPEST-. However, not every font has features which counteract the process of electromagnetic infiltration. The distinctive features of characters of font determine it. This article presents two sets of new computer fonts. These fonts are fully usable in everyday work. Simultaneously they make it impossible to obtain information using the non-invasive method. Names of these fonts are directly related to the shapes of the characters. Each character of these fonts is built only with vertical and horizontal lines. The differences between them consist in the different widths of the vertical lines. The Symmetrical Safe font is built from vertical lines with the same widths. The Asymmetrical Safe font is built from vertical lines with two different widths of lines. However, the appropriate proportions of the widths of the lines and clearances of each character of the safe font have to be met.
