SECURE INFORMATION TRANSMISSION BY EMBEDDING COMPRESSED TEXT DATA IN AN IMAGE

The transmission of patient medical information over the internet poses significant challenges due to the risk of unauthorized access by hackers who may illicitly get the data. This work proposes embedding compressed text data using DWT for safe information transport. The brain image of a patient is analyzed, and the patient details are integrated into the brain image utilizing the Least Significant Bit (LSB) approach. The patient's textual information is immediately incorporated into the brain imaging utilizing the Least Significant Bit (LSB) approach. The Discrete Wavelet Transform (DWT) is utilized to compress the patient's textual information, subsequently embedding it into the patient's brain image to produce a stego image of the brain. The performance characteristics of the embedding procedure utilizing DWT and those that do not utilize DWT are compared. The results obtained with DWT are much superior.
