Design Example: Maintaining Level of an Embankment

Design Example: Maintaining Level of an Embankment

Constructing a roadway embankment over uneven terrain requires precise leveling to ensure stability and proper drainage. Surveyors use a leveling instrument and staff to calculate ground elevations and determine the required fill material at each point along the embankment alignment.The process begins by positioning a leveling instrument near a benchmark with a known elevation. A backsight reading establishes the instrument height, which serves as a reference for subsequent measurements. A...

Routh-Hurwitz Criterion II

Routh-Hurwitz Criterion II

In the application of the Routh-Hurwitz criterion, two specific scenarios can arise that complicate stability analysis.
The first scenario occurs when a singular zero appears in the first column of the Routh table. This situation creates a division by zero issues. To resolve this, a small positive or negative number, denoted as epsilon (∈), is substituted for the zero. The stability analysis proceeds by assuming a sign for ∈. If ∈ is positive, any sign change in the first column of the Routh...

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

Woodward–Hoffmann Selection Rules and Microscopic Reversibility

Electrocyclic reactions, cycloadditions, and sigmatropic rearrangements are concerted pericyclic reactions that proceed via a cyclic transition state. These reactions are stereospecific and regioselective. The stereochemistry of the products depends on the symmetry characteristics of the interacting orbitals and the reaction conditions. Accordingly, pericyclic reactions are classified as either symmetry-allowed or symmetry-forbidden. Woodward and Hoffmann presented the selection criteria for...

Summary

This study introduces a novel multi-level image watermarking scheme (MIWC) for enhanced data traceability. MIWC utilizes the Chinese Remainder Theorem to embed multiple watermarks without overwriting, ensuring data integrity and security.

Keywords:

Area of Science:

Computer Science
Information Security
Digital Image Processing

Background:

Existing digital watermarking schemes struggle with overwriting issues during repeated watermark additions.
This limitation hinders multi-level data traceability and robust information embedding.

Purpose of the Study:

To propose a multi-level database image watermark embedding scheme (MIWC) for overcoming the limitations of existing methods.
To enable hierarchical and sequential embedding of watermark information for enhanced data traceability.

Main Methods:

The proposed MIWC scheme employs the Chinese Remainder Theorem for secret segmentation of watermark information.
Image preprocessing involves Haar wavelet transform and Bloom filter for pixel manipulation.
The scheme supports hierarchical and item-by-item watermark addition and traces the data flow chain.

Main Results:

MIWC demonstrates successful multi-level watermark embedding, a capability lacking in current schemes.
The scheme is reversible, efficient, and lightweight, even with multiple watermark layers.
High robustness against geometric attacks (rotation, scaling) and common image attacks (compression, noise) was confirmed.

Conclusions:

MIWC offers a practical solution for multi-level data traceability through its unique watermarking approach.
The scheme provides a secure, efficient, and robust method for embedding multiple watermarks in images.
MIWC holds significant practical application value in data security and integrity verification.
