Detailed Description
In order that those skilled in the art can understand and implement the present invention, the following embodiments of the present invention will be further described with reference to the accompanying drawings.
Fig. 1 shows a trusted identity authentication method in a communication session, including the steps of:
step 11: the calling party has a credible identity certificate issued by an authority organization;
step 12: a calling party initiates a session request to a called party, generates a communication token for the session at the same time, and transmits the communication token to the called party;
step 13: the called party receives a session request of the calling party, obtains a communication token associated with the session, and further obtains a trusted identity certificate of the calling party;
step 14: the called party verifies the credible identity certificate of the calling party, verifies the communication token by using the credible identity certificate of the calling party, and then determines a subsequent processing flow aiming at the session request according to a verification result and a pre-configured control strategy.
In the invention, the calling party/called party can be two parties of communication contacts such as sending image-text messages, making calls, language calls, video calls and the like.
Wherein the communication token may:
embedded in the SIP protocol to the called party user agent (e.g., ① embedded in the SIP protocol as a header to the called party user agent; or ② embedded in the SIP protocol as message content to the called party user agent); ③ may also be delivered in short messages to the called party user agent; the caller uploads the communication token to the cloud service and is then queried by the called party from the cloud service (e.g., ④ is delivered to the called party user agent using an out-of-band channel).
Specific treatment methods ① and ④ are listed below:
example 1: SIP-based communication authentication process
When the calling party terminal sends the INVITE message to the proxy, the communication token may be carried in the header of the message, and the INVITE message is finally delivered to the called party terminal via a plurality of proxies. The specific flow is as shown in fig. 2:
(1) the calling party generates SIP INVITE messages and calls the communication management service component of the home terminal to initiate a calling process;
(2) the communication management service component of the initiating terminal generates a communication token to be signed;
(3) the communication administration service component of the initiating terminal calls an authentication service signature communication token and puts the signed token into the header of the SIP INVITE message;
(4) SIP INVITE messages carrying communication tokens reach the receiving end communication administration service component through a plurality of proxy servers;
(5) the receiving end communication administration service component extracts the communication token from the SIP INVITE message and calls a verification service to verify the communication token;
(6) the verification service downloads the credible identity certificate of the calling party from the online certificate base according to the relevant fields in the communication token;
(7) the verification service verifies the validity of the identity certificate of the calling party, verifies the validity of the communication token and returns a verification result to the communication administration service component of the receiving end;
(8) and the receiving end communication administration service assembly processes the call according to a preset rule and displays a verification result and a ringing interface to the called party.
Example 2: communication authentication process based on out-of-band channel
When a calling party terminal initiates a call, the generated communication token is transmitted to a called party through an out-of-band channel, and the specific flow is as shown in fig. 3:
after a calling party initiates a call, an initiating terminal communication administration service assembly produces a communication token and calls an authentication service signature, and the signed communication token is put into a call positioning service on the cloud. The receiving-end communication administration service component invokes a validation service to validate the calling party as the call is delivered to the called party via the telephone network. The verification service acquires the communication token from the call positioning service according to the telephone numbers of the calling party and the called party, downloads the trusted identity certificate of the calling party from the online certificate bank according to the relevant fields in the communication token, verifies the validity of the identity certificate of the calling party and verifies the validity of the communication token by using the identity certificate, and replies the verification result to the receiving end communication management component. And the receiving end communication administration service assembly processes the call according to a preset rule and displays a verification result and a ringing interface to the called party.
In the above embodiments, among other things, the communication governance service component achieves the anti-harassment, anti-fraud goal by generating and verifying communication tokens. Communication governance service components, an authentication module, a verification module, a certificate library, call positioning services and the like involved in the communication governance process can be placed at different nodes according to different use scenes during actual deployment.
Referring to fig. 4, the present invention provides a trusted identity authentication system in communication session, including: a client and a server; the client is defined as a calling party or a called party according to the sending or receiving of the message in the communication; a user registers at a server through a client and acquires a trusted identity certificate;
the calling party client sends a session initialization request by adopting an SIP protocol in communication, and simultaneously generates a communication token for the session, and the communication token is embedded into an INVITE message of the SIP protocol and is transmitted to a called party client; and after receiving the session initialization request, the called party client acquires a communication token from the INVITE message, downloads the trusted identity certificate of the calling party from the online certificate library according to the relevant field in the communication token, then verifies the communication token by using the trusted identity certificate, and determines the subsequent processing flow aiming at the session request according to the verification result and the pre-configured control strategy.
Wherein, include: if the user is required to decide whether to allow the session to be established according to the verification result and the pre-configured control strategy, the called party client displays a ringing interface, and displays the verification result and the calling party credible identity information obtained according to the calling party credible identity certificate on the ringing interface; in the ringing interface, the user may take actions such as allowing the session to be established or denying the session to be established.
In the system of the present invention, the client can be realized as an APP on the user mobile terminal, or as a module on the communication gateway, or as an independent gateway device.
The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the present invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention. Therefore, the protection scope of the present patent shall be subject to the appended claims.
