Patent

CA 2541860

This disclosure describes systems and methods for processing voice data for secure transmission and secure receipt over a network, such as the Internet. The systems and methods include the processing of analog voice and digital information, including conversion of a voice signal into digital information (or of digital information into a voice signal) and transmission of digital information representing voice data over a network. The analog-to-digital conversion (and digital-to-analog conversion) includes coding and decoding digital information according to voice coding techniques and encrypting and decrypting digital information according to encryption techniques. The transmission of the digital information includes creation of a secure voice frame.

La présente divulgation décrit des systèmes et des méthodes qui permettent de traiter des données vocales pour la transmission sécurisée et la réception sécurisée sur un réseau, comme l'Internet. Ces systèmes et méthodes comprennent le traitement de signal vocal analogique et de données numériques, comprenant la conversion d'un signal vocal en données numériques (ou de données numériques en signal vocal) et la transmission de données numériques représentant des données vocales sur un réseau. La conversion analogique-numérique (et la conversion numérique-analogique) comprend le codage et le décodage de données numériques, selon les techniques de codage vocal, et le chiffrement et le déchiffrement de données numériques, selon les techniques de chiffrement. La transmission de données numériques comprend la création d'un cadre vocal sécurisé.
