Modified Least Significant Bit (MLSB)
Open accessAbstract
Now a day steganography plays a critical role in Information Security.Our work introduces modifications to existing steganography algorithm known as LSB "Least Significant Bit".The main idea of our work is to increase amount of data that can be hiding using LSB.In addition our algorithm encrypt data before hide it, which provide another level of protection over traditional LSB technique.
Overview

Written from the paper’s full text.
TL;DR
The paper modifies traditional LSB image steganography by converting 8-bit ASCII text into 5-bit codes with control symbols before hiding the bits in RGB pixel LSBs. It reports reduced bit requirements and a built-in form of encryption, demonstrated on an 18-character message hidden in a 160×160 image.
Key findings
- The algorithm represents characters and numbers with 5 bits instead of 8-bit ASCII, using control symbols: `1Bh` small letter, `1Ch` capital letter, `1Dh` space, `1Eh` number, and `1Fh` end of text.
- For the 18-character plaintext “STEGO with 05 bits,” ASCII requires `18 × 8 = 144` bits, while the proposed algorithm requires `22 × 5 = 110` bits, a difference of 34 bits.
- The same message needs at least `110/3` pixels, rounded to 37 pixels, and the experiment used a 160×160 pixel image; extraction returned the original message.
- The authors claim the conversion process provides built-in encryption because extracted bits are not understandable until converted back.
Methods
- Design: A 24-bit color image is used as the cover; message characters are converted from 8-bit ASCII to 5-bit codes, then hidden in the least significant bits of the Red, Green, and Blue components using LSB.
- Data/sample: One scenario with an 18-character text, “STEGO with 05 bits,” hidden in a 160×160 pixel image.
- Analysis: The paper compares bit requirements between ASCII and the proposed representation and verifies extraction by recovering the original message; no other quantitative analysis is reported.
Limitations
- Stated: If the text flips between small and capital letters for each character, the size will increase rather than decrease because of control symbols; the authors say such a scenario is rare.
- Evident: Evaluation is limited to a single 18-character message and one 160×160 image, with no security, detectability, robustness, or broader capacity analysis.
- Evident: No key or cryptographic algorithm is described for the claimed “encryption,” and no comparison is made against other enhanced LSB methods beyond the bit-count example.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
A language model drew the claims from the paper on 2026-10-23, under version 3 of the claim definition (model deepseek-v4.1-flash, prompt extract-v3).
A second model labelled each claim on 2026-10-23 (model jev-1.13-20260917, definition revision gold-guideline-v0.2).
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
