Abstract:
In the fastest digital world, people have much less time to consult a doctor in person for their health monitoring. It is easier for them to communicate in digital mode by using internet, web services, video or tele-conferencing, etc. But the communication between a patient and doctor must be confidential; While Internet is a wide open source, there may be some brutal attacks like hacking of information which are sent through e-mails. To make the communication or transmission of information in a secured manner, the user needs a Security algorithm for information which he/she wants to send over internet. That information may be text, image, audio or video. This article suggests an image authentication algorithm for providing security to medical images along with end user’s security ensured by using biometric identification. Cryptography based image authentication method is implemented and facial features are used as biometrics parameters.
