Abstract
A portable voiceprint-lock remote transmitting system includes a network voiceprint database and network communication devices connecting with the network voiceprint database on a network. The network voiceprint database includes a public-access voiceprint directory and a plurality of public-access voiceprint keys. The network communication device can download the public-access voiceprint key from the network voiceprint database, and the selected public-access voiceprint key can be used to encrypt electronic files to form a voiceprint lock. A receiver can decrypt the encrypted electronic files in a verification procedure. An operation method comprises the steps of: employing a network voiceprint database to provide public-access voiceprint keys; connecting a network communication device with the network voiceprint database on a network so as to obtain the public-access voiceprint key; employing the public-access voiceprint key to encrypt electronic files to form a voiceprint lock; and transmitting or delivering the encrypted electronic file to a receiver.
