PySpectra Exception: Binary is broken, please check the key again #1

Hei I got this issue "PySpectra Exception: Binary is broken, please check the key again" how to fix it?

Hi @rizalrorschach, thanks for reaching out!

The error message "PySpectra Exception: Binary is broken, please check the key again" typically occurs when the binary data that has been extracted from the image is inconsistent, which could be due to several reasons. Below are some potential causes and solutions:

  1. Incorrect Key: Ensure that the key used during the extraction process is the same as the one used during embedding. The pseudo-random noise generated by the key is critical for both embedding and extraction, and any mismatch could lead to incorrect results.
  2. Pixel Manipulation: If the image has been altered in any way (e.g., resized, compressed, or modified by filters), the pixel values might have changed, causing the embedded binary data to become corrupted. This system is designed to be not robust or fragile, meaning it is highly sensitive to any form of pixel manipulation. Even minor changes can disrupt the embedded data, leading to extraction failures. Ensure that the image has not undergone any manipulations or preprocessing after embedding.
  3. Scalar Value: Double-check the scalar value used in the Spread Spectrum embedding technique. The same scalar must be used for both embedding and extraction. If there is any discrepancy in this value, it can result in incorrect bit grouping and extraction failures.

Let me know if these suggestions help resolve the issue, or if you need further assistance!
