Abstract

Methods and systems for peer-to-peer communication are provided. In one example, a first device may receive, from a server, a pairing code and a first handshake code. The first device may transmit at least a first portion of the pairing code in a first broadcast message and receive, from the second device, a second broadcast message. The first device may authenticate the second device based on at least a second portion of the pairing code in the second broadcast message. The first device may establish a wireless peer-to-peer communication channel with the second device, and receive, from the second device, a second handshake code via the wireless peer-to-peer communication channel. The first device may authorize the second party to engage in an offline interaction with the first party based on the first handshake code and the second handshake code.

authenticating, by the first device, the second device based on at least a second portion of the pairing code in the second broadcast message;

responsive to authenticating the second device, establishing, by the first device, a wireless peer-to-peer communication channel with the second device;

receiving, by the first device from the second device, a second handshake code via the wireless peer-to-peer communication channel;

authorizing, by the first device, the second party to engage in the offline interaction with the first party based on a relationship between the first handshake code and the second handshake code; and

responsive to authorizing the second party, performing, by the first device, one or more actions to facilitate the offline interaction.

2. The method of claim 1, further comprising:

splitting, by the first device, the pairing code into the first portion and the second portion;

transmitting, by the first device, the first portion of the pairing code; and

authenticating the second device based on determining that the second portion of the pairing code included in the second broadcast message and the first portion of the pairing code form the pairing code.

3. The method of claim 1, wherein each of the first portion of the pairing code and each of the second portion of the pairing code comprises an entirety of the pairing code.

4. The method of claim 1, wherein authorizing the second party to engage in the offline interaction with the first party based on a relationship between the first handshake code and the second handshake code comprises determining that the second handshake code is identical to the first handshake code.

5. The method of claim 1, wherein the first handshake code is encrypted with a public key of the first device and is capable of being decrypted only with a private key of the first device;

and

wherein the method further comprises;

decrypting, by the first device, the first handshake code using the private key of the first device; and

authorizing the second party based on comparing the decrypted first handshake code with the second handshake code.

6. The method of claim 1, further comprising:

transmitting, by the first device to the server, a third handshake code before transmitting the broadcast message, to enable the server to transmit the third handshake code to the second device; and

transmitting, by the first device to the second device, a fourth handshake code via the wireless peer-to-peer communication channel, to enable the second device to authorize the first party to engage in the offline interaction with the second party based on a relationship between the third handshake code and the fourth handshake code.

7. The method of claim 1, further comprising:

transmitting, by the first device to the second device, a copy of the first handshake code via the wireless peer-to-peer communication channel to enable the second device to authorize the first party to engage in the offline interaction with the second party.

8. The method of claim 1, further comprising:

receiving, by the first device from the server, scheduling information for the offline interaction; and

transmitting, by the first device, the first broadcast message based on determining that a current time at the first device and a current location of the first device match, respectively, a scheduled time and a scheduled location included in the scheduling information.

9. The method of claim 8, further comprising:

receiving, by the first device from the server, a token that includes the scheduling information, the pairing code, and the first handshake code.

10. An apparatus comprising:

a memory that stores a set of instructions; and

a hardware processor configured to execute the set of instructions to;

transmit, to a server, a request to initiate an offline interaction with a second device, the offline interaction not hosted by the server, the request including credential information of a first party associated with the apparatus;

receive, from the server, a pairing code and a first handshake code, the pairing code for authenticating the second device and the first handshake code for authorizing a second party associated with the second device to engage in the offline interaction with the first party, the pairing code and the first handshake code being provided to the apparatus after the server authenticates the first party using the credential information;

transmit at least a first portion of the pairing code in a first broadcast message that is capable of being detected by the second device;

receive, from the second device, a second broadcast message;

authenticate the second device based on at least a second portion of the pairing code in the second broadcast message;
