| contents | Since the 1990s, the telephone has been the primary mode of communication. However, Voice over Internet Protocol (VoIP), which is a highly straightforward and affordable form of data transfer, is now becoming an important part of daily communication. VoIP is the technology that makes it possible to send speech and multimedia data packets across either a public or private IP network. However, a cyberattack known as a man-in-the-middle attack poses a serious concern in transferring data through any network. Therefore, the authors have designed a system that sends voice over the internet within the range of a router using encrypted data transfer. An embedded system comprising an electret microphone, Embedded C, Particle Photon microcontroller, and Internet of Things (IoT) technology is developed. Due to its compact size, this type of device may be incorporated into automobiles, surveillance systems, or covert listening tools. The VoIP system gathers sound signals using the MAX9814 microphone, while the Particle Photon microcontroller securely transmits the data. Devices with access can download data from the VoIP systems Transmission Control Protocol (TCP) server. The accessed device stores the audio locally and uploads the corresponding data to Google Drive. This VoIP system provides a secure method of communication while conserving the integrity of the original signal. |
