A Secure Lightweight SMS Spam Detection Framework with Robustness to Text Obfuscation Attacks

Experimental evaluations on the UCI SMS Spam Collection dataset demonstrate that the TF-IDF-PCA-DT pipeline achieves a detection accuracy of 99% while reducing model size by 77% and inference time by 75%, demonstrating the practicality of the proposed framework for real-world deployment in resource-constrained environments.
