Abstract

The present application discloses methods, devices and systems for information verification, and in particular for multi-user verification for transactions such as online payment transactions. An online account, such as a payment account, can be registered as a multi-user verification account, which requires at least two users to verify a transaction. After receiving a verification request from a first user, a server verifies first verification information (e.g. voiceprint information) from the first user and second verification information (e.g. voiceprint information) from the second user, so that the server may approve or deny the pending transaction in accordance with a comparison of the first and second verification information against respective verification information stored in association with the multi-user verification account.

First claim

What is claimed is:

1. A method of verifying an electronic transaction, the method comprising:
at a server associated with an instant messaging (IM) application, the IM application having a plurality of IM accounts, including first and second accounts associated with first and second users, respectively:
receiving, from a first electronic device running the IM application, a first instant message including: (i) transaction information for a pending electronic transaction initiated by the first user, the transaction information identifying the first IM account and a payment account linked to the first IM account, (ii) first biometric information associated with the first user, wherein the first user controls the first electronic device, and (iii) an authentication code;
comparing the first biometric information against first reference biometric information associated with the first user, the first reference biometric information being electronically stored at the server in association with the first IM account;
in response to the first biometric information passing the comparison:
determining that the second IM account is also linked with the payment account;
sending, to a second electronic device running the IM application, the authentication code previously sent from the first electronic device, and a second instant message including a request for second biometric information associated with the second user in response to said determining, wherein the second user controls the second electronic device;
receiving, from the second electronic device in response to the request and in response to verifying the authentication code, a third instant message including: (i) second biometric information associated with the second user, and (ii) a denial, specified by the second user through the second electronic device, to be performed by the server in association with the pending electronic transaction;
comparing the second biometric information against second reference biometric information associated with the second user, the second reference biometric information being electronically stored at the server in association with the second IM account; and
in response to the second biometric information passing the comparison, denying the pending electronic transaction as specified by the second user and sending, to the first electronic device running the IM application, a fourth instant message including a denial of the pending electronic transaction.

2. The method of claim 1 , wherein the request, when received by the second electronic device, causes the second electronic device to display an interface of the IM application for inputting: (i) the second biometric information associated with the second user, and (ii) the denial to be performed by the server in association with the pending electronic transaction.

3. The method of claim 2 , wherein the second electronic device generates the third instance message in response to the second user inputting the second biometric information and the denial through the interface of the IM application.

4. The method of claim 1 , wherein determining that the second IM account is linked with the payment account is performed using a mapping table.

5. The method of claim 1 , wherein the second instant message further includes purchase order information associated with the pending electronic transaction.

6. The method of claim 1 , wherein:
the first biometric information associated with the first user includes a voiceprint of the first user; and
the second biometric information associated with the second user includes a different voiceprint of the second user.

7. The method of claim 1 , further comprising, at the server:
in response to the first biometric information not passing the comparison, denying the pending electronic transaction; and/or
in response to the second biometric information not passing the comparison, denying the pending electronic transaction.

8. A server associated with an instant messaging (IM) application, the server comprising:
one or more processors; and
memory storing instructions, the instructions, when executed by the one or more processors, cause the server to:
receive, from a first electronic device running the IM application, a first instant message including: (i) transaction information for a pending electronic transaction initiated by a first user, the transaction information identifying a first IM account of the IM application associated with the first user, and a payment account linked to the first IM account, (ii) first biometric information associated with the first user, wherein the first user controls the first electronic device, and (iii) an authentication code;
compare the first biometric information against first reference biometric information associated with the first user, the first reference biometric information being electronically stored at the server in association with the first IM account;
in response to the first biometric information passing the comparison:
determine that a second IM account of the IM application is also linked with the payment account, the second IM account being associated with a second user;
send, to a second electronic device running the IM application, the authentication code previously sent from the first electronic device, and a second instant message including a request for second biometric information associated with the second user in response to said determining, wherein the second user controls the second electronic device;
receive, from the second electronic device in response to the request and in response to verifying the authentication code, a third instant message including: (i) second biometric information associated with the second user, and (ii) a denial, specified by the second user through the second electronic device, to be performed by the server in association with the pending electronic transaction;
compare the second biometric information against second reference biometric information associated with the second user, the second reference biometric information being electronically stored at the server in association with the second IM account; and
in response to the second biometric information passing the comparison, deny the pending electronic transaction as specified by the second user and send, to the first electronic device running the IM application, a fourth instant message including a denial of the pending electronic transaction.

9. The server of claim 8 , wherein the request, when received by the second electronic device, causes the second electronic device to display an interface of the IM application for inputting: (i) the second biometric information associated with the second user, and (ii) the denial to be performed by the server in association with the pending electronic transaction.

10. The server of claim 9 , wherein the second electronic device generates the third instance message in response to the second user inputting the second biometric information and the denial through the interface of the IM application.

11. The server of claim 8 , wherein determining that the second IM account is linked with the payment account is performed using a mapping table.

12. The server of claim 8 , wherein the second instant message further includes purchase order information associated with the pending electronic transaction.

13. The server of claim 8 , wherein the instructions, when executed by the one or more processors, further cause the server to:
in response to the first biometric information not passing the comparison, deny the pending electronic transaction; and/or
in response to the second biometric info
