Claim 2

In a voice message system having a plurality of user voice mailboxes, the method comprising the steps of encrypting messages designated for a plurality of designated users using a unique encrypting key for each of said users, storing the encrypted messages, separately storing the unique encrypting keys from said encrypted messages, decrypting the stored messages when instructed by each of said designated users using decrypting keys corresponding to said stored encrypting keys for each of said users, and playing the decrypted messages to said designated users.

Claim 3

In a voice message system having a plurality of user voice mailboxes, the method comprising the steps of encrypting messages intended for designated users of said system, using unique encrypting keys corresponding to each of said designated users, including encrypting a plurality of messages for said designated user of said system with different unique encrypting keys for each of said plurality of messages, storing the encrypted messages, separately storing the unique encrypting keys from said encrypted messages, decrypting the stored encrypted messages when instructed by each of said designated users, using decrypting keys corresponding to each of said stored unique encrypting keys, playing the decrypted messages to said respective designated users.

Claim 4

In a voice message system having a plurality of user voice mailboxes, the method comprising the steps of encrypting messages intended for designated users of said system, using unique encrypting keys corresponding to each of said designated users, including encrypting a plurality of messages for said designated user of said system with different unique encrypting keys for each of said plurality of messages, storing the encrypted messages, separately storing the unique encrypting keys from said encrypted messages, decrypting the stored encrypted messages when instructed by each of said designated users, using decrypting keys corresponding to each of said stored unique encrypting keys, playing the decrypted messages to said respective designated users.

Claim 5

The method of claim 2 including the step of decrypting the plurality of encrypted stored messages using a different unique decrypting key for each of said stored encrypted messages.

Claim 6

In a voice message system having a plurality of user voice mailboxes, the method comprising the steps of encrypting a first message intended for a first designated user of said system, using a first unique encrypting key corresponding to said first designated user, storing the first encrypted message, separately storing said first unique encrypting key from said first encrypted message, decrypting the stored encrypted message when instructed by said designated users, using a decrypting key corresponding to said stored unique encrypting key, playing the first decrypted message, encrypting a second message designated for a second, different user using a second unique encrypting key corresponding to said second designated user, storing the second encrypted message, separately storing the said second unique encrypting key from said second encoded message, decrypting the second encrypted message using a second decrypting key corresponding to said stored second encrypting key, and playing the second decrypted message to said respective designated users.

Claim 7

In a voice message system having a plurality of user voice mailboxes, the method comprising the steps of encrypting a first message intended for a first designated user of said system, using a first unique encrypting key corresponding to said first designated user, storing the first encrypted message, separately storing said first unique encrypting key from said first encrypted message, decrypting the stored encrypted message when instructed by said designated users, using a decrypting key corresponding to said stored unique encrypting key, playing the first decrypted message, encrypting a second message designated for a second, different user using a second unique encrypting key corresponding to said second designated user, storing the second encrypted message, separately storing the said second unique encrypting key from said second encoded message, decrypting the second encrypted message using a second decrypting key corresponding to said stored second encrypting key, and playing the second decrypted message to said respective designated users.
