Watermarking Using Decimal Sequences

TL;DR

This paper proposes a watermarking method for black and white images using decimal sequences in a CDMA system, offering greater flexibility over traditional PN sequences by allowing prime number selection.

Contribution

It introduces the use of decimal sequences in CDMA-based watermarking, enhancing flexibility and customization compared to existing PN sequence methods.

Findings

Decimal sequences provide more flexible watermarking options.

The system was implemented in Matlab 6.5.

Decimal sequences outperform PN sequences in adaptability.

Abstract

This paper introduces the use of decimal sequences in a code division multiple access (CDMA) based watermarking system to hide information for authentication in black and white images. Matlab version 6.5 was used to implement the algorithms discussed in this paper. The advantage of using d-sequences over PN sequences is that one can choose from a variety of prime numbers which provides a more flexible system.
