Abstract
A system is provided for securing voice mail messages. The system includes a packet network and a telephony device that is coupled to the packet network. The system also includes a voice mail system that is coupled to the packet network and that receives a voice mail message from a caller attempting to communicate with a user of the telephony device. The voice mail system encrypts the voice mail message using a public key associated with the telephony device and stores the encrypted voice mail message in an open file system coupled to the packet network.
Claims32
A method for securing voice mail messages, comprising:
- receiving a telephone call from a caller attempting to communicate with a user of a telephony device, the telephony device coupled to a packet network;
- indicating to the caller that the user is not available to communicate with the caller;
- receiving a voice mail message from the caller for the user of the telephony device;
- encrypting the voice mail message using a public key associated with the telephony device;
- and
- storing the encrypted voice mail message in a file system such that the encrypted voice mail message is accessible from the packet network;
- wherein encrypting the voice mail message using the public key associated with the telephony device comprises encrypting the voice mail message as it is received without storing the unencrypted voice mail message.
A system for securing voice mail messages in a packet network, comprising:
- a packet network;
- a telephony device coupled to the packet network;
- and
- a voice mail system coupled to the packet network and operable to receive a voice mail message from a caller attempting to communicate with a user of a telephony device coupled to the packet network, the voice mail system further operable to encrypt the voice mail message using a public key associated with the telephony device and to store the encrypted voice mail message in an open file system coupled to the packet network;
- wherein encrypting the voice mail message using the public key associated with the telephony device comprises encrypting the voice mail message as it is received without storing the unencrypted voice mail message.
Voice mail security software embodied in a computer-readable medium and operable to perform the following steps:
- receiving a telephone call from a caller attempting to communicate with a user of a telephony device, the telephony device coupled to a packet network;
- indicating to the caller that the user is not available to communicate with the caller;
- receiving a voice mail message from the caller for the user of the telephony device;
- encrypting the voice mail message using a public key associated with the telephony device;
- and
- storing the encrypted voice mail message in a file system such that the encrypted voice mail message is accessible from the packet network;
- wherein encrypting the voice mail message using the public key associated with the telephony device comprises encrypting the voice mail message as it is received without storing the unencrypted voice mail message.
