Expected response one-time password
View Patent ↗A system may generate a seed one-time password (OTP). The system may also perform steps including transmitting the seed OTP to a user device, receiving a response OTP from the user device, and calculating an expected response OTP by applying a function to the seed OTP. The system may then compare the response OTP to the expected response OTP and send a result in response to comparing the response OTP to the expected response OTP.
1. A method comprising:
transmitting, by a processor, a seed one-time password (OTP) to a user device;
receiving, by the processor, a response OTP generated by the user device, in response to an integrity module confirming that the user device is in good health based on the seed OTP being passed to a security utilities software development kit (SDK) on the user device;
calculating, by the processor, an expected response OTP by applying a function to the seed OTP, wherein the function is based on an identifier of the user device and a fingerprint of the user device;
determining, by the processor, that the response OTP satisfies the expected response OTP; and
sending, by the processor, a result in response to the determining.
2. The method of claim 1 , further comprising generating, by the processor, the seed OTP.
3. The method of claim 1 , further comprising transmitting, by the processor, the seed OTP to an OTP validation server.
4. The method of claim 1 , wherein the security utilities SDK is in communication with an OTP listening service.
5. The method of claim 1 , wherein the response OTP is different from the seed OTP.
6. The method of claim 1 , wherein the response OTP is generated using the function.
7. The method of claim 1 , wherein in response to receiving the result from the processor, the user device requests confirmation.
8. The method of claim 1 , further comprising receiving, by the processor, a request for the seed OTP, wherein the request includes a device identifier associated with the user device and a device fingerprint associated with the user device.
9. The method of claim 1 , wherein in response to receiving the result from the processor, the user device displays a success notification screen, wherein the success notification screen is displayed along with at least one of a service name request, a purpose, a time, a merchant, a merchant locator, or an amount.
10. The method of claim 1 , wherein the response OTP is transmitted by the user device to the processor in response to an authorization button being selected.
11. The method of claim 1 , wherein the seed OTP is transmitted to the user device with an authorization payload including at least one of a service identifier, a purpose, a time, a date, a merchant identifier, or an amount of the seed OTP for display with an authorization button.
12. The method of claim 1 , wherein the seed OTP is only valid for a predetermined time period.
13. A computer-based system, comprising:
a processor; and
a tangible, non-transitory memory configured to communicate with the processor, the tangible, non-transitory memory having instructions stored thereon that, in response to execution by the processor, cause the processor to perform operations comprising:
transmitting, by the processor, a seed OTP to a user device;
receiving, by the processor, a response OTP generated by the user device, in response to an integrity module confirming that the user device is in good health based on the seed OTP being passed to a security utilities software development kit (SDK) on the user device;
calculating, by the processor, an expected response OTP by applying a function to the seed OTP, wherein the function is based on an identifier of the user device and a fingerprint of the user device;
determining, by the processor, that the response OTP satisfies the expected response OTP; and
sending, by the processor, a result in response to the determining.
14. The method of claim 1 , wherein the response OTP is received from the user device via text message.
15. The method of claim 1 , further comprising transmitting, by the processor, the seed OTP to the user device via text message.
16. The system of claim 13 , wherein the security utilities SDK is in communication with an OTP listening service.
17. The system of claim 13 , wherein the response OTP is different from the seed OTP.
18. The system of claim 13 , wherein the response OTP is generated using the function.
19. The system of claim 13 , further comprising receiving, by the processor, a request for the seed OTP, wherein the request includes a device identifier associated with the user device and a device fingerprint associated with the user device.
20. An article of manufacture including a non-transitory, tangible computer readable storage medium having instructions stored thereon that, in response to execution by a processor, cause the processor to perform operations comprising:
transmitting, by the processor, a seed OTP to a user device;
receiving, by the processor, a response OTP generated by the user device, in response to an integrity module confirming that the user device is in good health based on the seed OTP being passed to a security utilities software development kit (SDK) on the user device;
calculating, by the processor, an expected response OTP by applying a function to the seed OTP, wherein the function is based on an identifier of the user device and a fingerprint of the user device;
determining, by the processor, that the response OTP satisfies the expected response OTP; and
sending, by the processor, a result in response to the determining.
