## 6 Conclusions  
We developed a novel method for image encryption, i.e., a 3D Gauss map from the 1D Gauss map. Further, the method is blended with the other three strong chaos maps as the logistic map, Arnold cat map, and sine map, which in integration makes a powerful quad key structure with a very large key and is very difficult to breach. To make the system lightweight (in terms of the processing speed), the SVD compression scheme is also employed. One major benefit of the proposed method is that it gives the user some flexibility in terms of compression, so that the user may tailor the amount of compression applied to the visual data to meet the needs of storage without sacrificing security. \begin{table}

In addition, the suggested approach was evaluated in terms of calculation time. This work can be expanded in the future to include video compression and video security. According to the experimental results and security analysis, the suggested technique has an excellent encryption effect, high key sensitivity, strong pixel randomization, and poor correlation of neighboring pixels. Additionally, it is opposed to standard statistical and differential attacks. Compared to existing work, the suggested approach is highly secure and suitable for lightweight transmission.
