Providing privacy for electronic voting using encryption
In some embodiments, techniques for voting and visual cryptography may include various enhancements.
1. A method for providing privacy for electronic voting on a computing device, the method comprising:
generating a file representing a ballot for voting, the file including a vote of a user;
performing a first encryption of the file to generate a first encrypted file after the vote is included by the user;
adding a receipt associated with the user to the first encrypted file; and
performing a second encryption of the first encrypted file with the receipt to generate a second encrypted file.
2. The method of claim 1 , wherein performing the first encryption of the file includes encrypting the file with a public half of a public/private key pair.
3. The method of claim 1 , wherein adding the receipt includes enabling the user to review a list of receipts and embedding the receipt data to the first encrypted file.
4. The method of claim 1 , further comprising adding a user identification to the second encrypted file.
5. The method of claim 4 , wherein the user identification includes a cryptographic signature of the user.
6. The method of claim 4 , further comprising performing a third encryption of the second encrypted file with the user identification to generate a third encrypted file.
7. The method of claim 6 , further comprising adding an authentication credential to the third encrypted file.
8. The method of claim 7 , wherein the authentication credential includes a passcode previously registered by the user to a voting registry.
9. The method of claim 7 , further comprising performing a fourth encryption of the third encrypted file with the authentication credential to generate a fourth encrypted file.
10. The method of claim 9 , further comprising transmitting the fourth encrypted file over a network to a voting registry.
11. A non-transitory computer readable medium storing instructions that, when executed by a processor, cause the processor to perform steps comprising:
generating a file representing a ballot for voting, the file including a vote of a user;
performing a first encryption of the file to generate a first encrypted file after the vote is included by the user;
adding a receipt associated with the user to the first encrypted file; and
performing a second encryption of the first encrypted file with the receipt to generate a second encrypted file.
12. The non-transitory computer readable medium of claim 11 , wherein the instructions cause the processor to perform the first encryption of the file by encrypting the file with a public half of a public/private key pair.
13. The non-transitory computer readable medium of claim 11 , wherein the instructions cause the processor to add the receipt by enabling the user to review a list of receipts and embedding the receipt data to the first encrypted file.
14. The non-transitory computer readable medium of claim 11 , wherein the instructions further cause the processor to add a user identification to the second encrypted file.
15. The non-transitory computer readable medium of claim 14 , wherein the user identification includes a cryptographic signature of the user.
16. The non-transitory computer readable medium of claim 14 , wherein the instructions further cause the processor to perform a third encryption of the second encrypted file with the user identification to generate a third encrypted file.
17. The non-transitory computer readable medium of claim 16 , wherein the instructions further cause the processor to add an authentication credential to the third encrypted file.
18. The non-transitory computer readable medium of claim 17 , wherein the authentication credential includes a passcode previously registered by the user to a voting registry.
19. The non-transitory computer readable medium of claim 17 , wherein the instructions further cause the processor to perform a fourth encryption of the third encrypted file with the authentication credential to generate a fourth encrypted file.
20. The non-transitory computer readable medium of claim 19 , wherein the instructions further cause the processor to transmit the fourth encrypted file over a network to a voting registry.
