One of the applications of modern technology in telemedicine is video conferencing. An alternative to traveling to attend a conference or meeting, video conferencing is becoming increasingly popular among hospitals. By using this technology, doctors can help patients who are unable to physically visit hospitals. Video conferencing particularly benefits patients from rural areas, where good doctors are not always available. Telemedicine has proven to be a blessing to patients who have no access to the best treatment.  

A telemedicine system consists of customized hardware and software at two locations, namely, at the patient’s and the doctor’s end. In such cases, the video streams of the conferencing parties may contain highly sensitive information. Thus, real-time data security is one of the most important requirements when designing video conferencing systems. This study proposes a secure framework for video conferencing systems and a complete management solution for secure video conferencing groups. Java media framework application programming interface classes are used to design and test the proposed secure framework. Real-time transport protocol over user datagram protocol is used to transmit the encrypted audio and video streams, and RSA and AES algorithms are used to provide the required security services. Results show that the encryption algorithm insignificantly increases the video conferencing computation time iii

Real-time communication is probably what jumps to mind when most people think of telehealth technology. It happens when the patient is at one location and the provider is at another and they connect using a video-enabled device and a telephone or computer audio. Sometimes the patient might be at a healthcare facility with a provider and they establish communications with a specialist at a remote location, other times the patient might not be at a medical office at all. He or she might join the encounter from work or the office, for example. Many state laws require insurers to reimburse for these types of video visits. Most don’t have a similar stipulation for telephone calls that don’t involve video.
