The rapid growth of immigrants is a veritable menace for most state authorities. Aside from the hazards of population overcrowding, they create the risk of health hazards. According to recent medical statistics, international immigrants are the carriers of communicable diseases. In addition to tightened border controls, the strict and transparent visa approval process through proper medical diagnoses may play a vital role in addressing this problem. This requires the safe, secure, and prompt transmission of medical reports from recognized medical centers to embassies without violating the Health Insurance Portability and Accountability Act (HIPAA). This article introduces a novel transfer system of visa applicant medical reports for processing through multilayer security. Both cryptography and steganography are used here to ensure security. This nearly foolproof system helps to reduce the incorrect identification of visa applicants and quickens the visa-processing system. At the same time, it helps to control the spread of communicable diseases. © 2012 IEEE.
