Abstract

An information interaction method and device are provided. In the method, the device establishes a connection with a wearable device. The device sends information to be interacted corresponding to a logged-in ID to the wearable device via the connection. The device receives a first encrypted result returned by the wearable device. The device generates a first verifying factor corresponding to the first encrypted result with a predetermined algorithm. The device sends the information to be interacted and the first verifying factor in an associated manner to a server. The device receives a message indicating that an interaction is finished, where the message is sent if the server determines that a second verifying factor generated with the predetermined algorithm and corresponding to a second encrypted result matches the first verifying factor. The second encrypted result is obtained by encrypting the information to be interacted by the server with the pre-stored encryption key.

Claims

generating, by the electronic device, a first verifying factor corresponding to the first encrypted result with a predetermined algorithm;

sending, by the electronic device, the information and the first verifying factor in an associated manner to a server; and

receiving, by the electronic device, a message indicating that an interaction is finished, wherein the message is sent if the server determines that a second verifying factor matches the first verifying factor, wherein the second verifying factor is generated with the predetermined algorithm and corresponds to a second encrypted result, wherein the second encrypted result is obtained by encrypting the information by the server with the pre-stored encryption key.

2. The information interaction method according to claim 1, further comprising:

receiving the pre-stored encryption key sent by the wearable device; and

sending the pre-stored encryption key to the server such that the server stores the pre-stored encryption key and the logged-in ID in an associated manner.

3. The information interaction method according to claim 1, further comprising:

receiving the pre-stored encryption key sent by the server; and

transmitting the pre-stored encryption key to the wearable device via the connection such that the wearable device stores the pre-stored encryption key and the logged-in ID in an associated manner.

establishing, by an electronic device, a connection with a wearable device;

sending, by the electronic device, information at least partially related to a logged-in identification (ID) to the wearable device via the connection;

receiving, by the electronic device, an encrypted result returned by the wearable device, wherein the encrypted result is obtained by encrypting the information by the wearable device with a first encryption key corresponding to the logged-in ID;

sending, by the electronic device, the encrypted result to a server; and

receiving, by the electronic device, a message indicating that an interaction is finished, wherein the message is sent after a decryption operation on the encrypted result is performed by the server using a second encryption key matching with the first encryption key.

5. The information interaction method according to claim 4, further comprising:

receiving the first encryption key sent by the server; and

transmitting the first encryption key to the wearable device via the connection such that the wearable device stores the first encryption key and the logged-in ID in an associated manner.
