Generating barcodes utilizing cryptographic techniques
Various embodiments are generally directed to secure generation of barcodes using cryptographic techniques. An application may receive a request to generate a barcode. The application may receive encrypted data from a communications interface of a contactless card associated with an account. The application may receive, from a server, verification of the encrypted data and an encrypted authorization token associated with the account. The application may generate the barcode utilizing the encrypted authorization token.
1. An apparatus, comprising:
a processor circuit; and
a memory storing instructions which when executed by the processor circuit, cause the processor circuit to:
receive, by an application executing on the processor circuit, a request to generate a scannable code;
receive, by the application, encrypted data from a communications interface of a contactless card associated with an account;
receive, by the application and from a server, verification of the encrypted data and an encrypted authorization token associated with the account; and
generate, by the application, the scannable code utilizing the encrypted authorization token.
2. The apparatus of claim 1 , the memory storing instructions which when executed by the processor circuit, cause the processor circuit to:
display the scannable code on a display device.
3. The apparatus of claim 1 , wherein the scannable code is pre-configured by the encrypted authorization token to authorize a single transaction.
4. The apparatus of claim 3 , wherein the scannable code and the encrypted authorization token are configured to expire after the authorization of the single transaction.
5. The apparatus of claim 4 , wherein the single transaction is a payment transaction and the encrypted authorization token is a payment token, and wherein the payment token is associated with a monetary limit.
6. The apparatus of claim 1 , the memory storing instructions which when executed by the processor circuit, cause the processor circuit to:
decrypt, by the application, the encrypted authorization token to authorize a transaction.
7. The apparatus of claim 1 , the memory storing instructions which when executed by the processor circuit, cause the processor circuit to, prior to receiving the verification of the encrypted data:
transmit, by the application, the encrypted data to the server.
8. A non-transitory computer-readable storage medium storing instructions that when executed by a processor circuit cause the processor circuit to:
receive, by an application executing on the processor circuit, a request to generate a scannable code;
receive, by the application, encrypted data from a communications interface of a contactless card associated with an account;
receive, by the application and from a server, verification of the encrypted data and an encrypted authorization token associated with the account; and
generate, by the application, the scannable code utilizing the encrypted authorization token.
9. The non-transitory computer-readable storage medium of claim 8 , storing instructions that when executed by the processor circuit cause the processor circuit to:
display, by the application, the scannable code on a display device.
10. The non-transitory computer-readable storage medium of claim 8 , wherein the scannable code is pre-configured by the encrypted authorization token to authorize a single transaction.
11. The non-transitory computer-readable storage medium of claim 10 , wherein the scannable code and the encrypted authorization token are configured to expire after the authorization of the single transaction.
12. The non-transitory computer-readable storage medium of claim 11 , wherein the single transaction is a payment transaction and the encrypted authorization token is a payment token, and wherein the payment token is associated with a monetary limit.
13. The non-transitory computer-readable storage medium of claim 8 , storing instructions that when executed by the processor circuit cause the processor circuit to:
decrypt, by the application, the encrypted authorization token to authorize a transaction.
14. The non-transitory computer-readable storage medium of claim 8 , storing instructions that when executed by the processor circuit cause the processor circuit to, prior to receiving the verification of the encrypted data:
transmit, by the application, the encrypted data to the server.
15. A method, comprising:
receiving, by an application executing on a processor, a request to generate a scannable code;
receiving, by the application, encrypted data from a communications interface of a contactless card associated with an account;
receiving, by the application and from a server, verification of the encrypted data and an encrypted authorization token associated with the account; and
generating, by the application, the scannable code utilizing the encrypted authorization token.
16. The method of claim 15 , further comprising:
displaying, by the application, the scannable code on a display.
17. The method of claim 15 , wherein the scannable code is pre-configured by the encrypted authorization token to authorize a single transaction.
18. The method of claim 17 , wherein the scannable code and the encrypted authorization token are configured to expire after the authorization of the single transaction.
19. The method of claim 18 , wherein the single transaction is a payment transaction and the encrypted authorization token is a payment token, and wherein the payment token is associated with a monetary limit.
20. The method of claim 19 , further comprising:
transmitting, by the application, the encrypted data to the server prior to receiving the verification of the encrypted data; and
decrypting, by the application, the encrypted authorization token to authorize a transaction.
