Avaliação de Métodos Esteganográficos em Imagens Médicas (original) (raw)

Digital Imaging and Communications In Medicine (DICOM) is a well-established standard regarding storage, printing, and transmission of medical images. However, there are no security methods that preserve metadata confidentiality, nor image authenticity. This work assesses three steganographic methods-least significant bit insertion (LSB), division into blocks, mean change modified method (MCMM)-and verify their feasibility for clinical use in medical imaging. Integrating MCMM in DICOM standard would provide increased information security in medical imaging, deterring fraud, privacy invasion, while preserving diagnostic information.
