Abstract

The present invention relate to systems and methods for conducting secured telephony and transaction authentication via electronic devices. More specifically, the embodiments of the present invention relate to systems and methods for conducting secure networked telephony, including but not limited to communications over the internet, other computer networks, wired or wireless networks, or audio, video or multi-media.

Claims

1. A method of sending data from a first user to a second user during a communication session comprising the steps of:

generating a key;

encrypting said key to form an encrypted key;

sending said encrypted key to the second user for decryption of said encrypted key at said second user;

initiating the communication session between the first user and the second user;

encrypting first data relating to a first communication event with said key to form first encrypted data; and

sending said first encrypted data relating to a first communication event from said first user to said second user for decryption of said first encrypted data using said key decrypted by said second user.

2. The method of claim 1 wherein said key is a symmetric key.

3. The method of claim 1 further comprising the steps of:

generating a passcode for decrypting said encrypted key; and

sending said passcode to said second user for decrypting said key.

4. The method of claim 1 wherein said passcode for decrypting said key is sent to said second user separately from said sending of said key.

5. The method of claim 1 further comprising the steps of:

generating a plurality of keys;

encrypting said plurality of keys to form a plurality of encrypted keys; and

sending said plurality of encrypted keys to the second user for decryption of at least one of said plurality of encrypted keys to form at least one decrypted key, said at least one decrypted key for decrypting said first encrypted data.

6. The method of claim 5 further comprising the step of:

sending said plurality of encrypted keys to the second user for decryption of more than one of said plurality of encrypted keys to form more than one decrypted keys, said more than one decrypted keys for decrypting said first encrypted data.

7. The method of claim 5 wherein each of said plurality of encrypted keys is decryptable by one or more passcodes, said one or more passcodes being sent to said second user separately from said plurality of encrypted keys.

8. The method of claim 6 further comprising the steps of:

decrypting said first encrypted data with a first key at a first time during the communication session; and

decrypting said first encrypted data with a second key at a second time during the communication session.

9. The method of claim 1 further comprising the steps of:

sending unencrypted data at a first time during the communication session between the first user and the second user; and

encrypting said data at a second time during the communication session.

10. The method of claim 1 further comprising the steps of:

encrypting second data relating to a second communication event to form second encrypted data; and

sending said second encrypted data relating to a second communication event to said receiver for decrypting said second encrypted data.

11. The method of claim 1 further comprising the steps of:

applying a key time limit having parameters set by said first user, such that said key is usable to decrypt said first data only when designated by said set parameters of said key time limit.

12. The method of claim 1 further comprising the steps of:

sending said encrypted key to a plurality of users for decryption of said encrypted key at said plurality of users;

initiating the communication session between the first user and plurality of users; and

sending said first encrypted data from said first user to said plurality of users for decryption of said first encrypted data using said key.

13. A system for sending data from a first user to a second user during a communication session comprising:

an application associated with an electronic device, said application providing for the generation of a key;

the encryption of said key;

the sending of said key to a second user for decryption of said encrypted key at said second user;

the initiation of the communication session between the first user and the second user;

the encryption of first data with said key to form first encrypted data; and

the sending of said first encrypted data relating to a first communication event from said first user to said second user for decryption of said first encrypted data using said key decrypted by said second user; and

a network for the sending of said first encrypted data from said first user and said second user.

14. The system of claim 13 wherein said electronic device comprises a PDA.

15. The system of claim 13 wherein said electronic device is a cellular telephone.

16. The system of claim 13 wherein said electronic device is selected from the group consisting of an IP/SIP, a VoIP telephone, a dual-phone, a radio, and a television.

17. The system of claim 13 wherein said electronic device is a personal computer.

18. The system of claim 13 further comprising a memory device for storage of said application.

19. The system of claim 13 wherein said network is the internet.

20. The system of claim 13 wherein said network is a publicly switched telephone network.
