Encrypted electronic gaming ticket
An electronic ticket ( 30 ) is disclosed which includes a date of purchase ( 31 ), a ticket identifier ( 32 ), wager attributes ( 33 ), a draw identifier ( 35 ), a draw date ( 36 ), draw numbers ( 37 ), an authority authorized retail identifier ( 38 ), and an authority authorized retail terminal identifier ( 39 ). The electronic ticket ( 30 ) may be a displayed version of an image file, or other electronic file type, which is stored and displayed upon a mobile computer device ( 50 ). The image file creates a matrix of pixels which together form a picture including text which form the electronic ticket. The image pixels are manipulated by steganographic techniques, to encode various attributes, including the manipulation of the least significant digits of the numeric value of the pixel color.
1. An anonymous electronic bearer instrument comprising an electronic file containing a humanly detectable first dataset that contains a humanly undetectable second dataset, said humanly undetectable second dataset containing claim validation information being selected by or for a claimant and encrypted using a cryptographic key known only to an authority, said humanly undetectable second dataset including said claim validation information also being encoded into the humanly detectable first dataset the resulting electronic file including said claim validation information and being transferred from the authority to the claimant, said humanly undetectable second dataset being undetectable to the claimant.
2. The electronic bearer instrument of claim 1 wherein said electronic file is an image file.
3. The electronic bearer instrument of claim 1 wherein said electronic file is an audio file.
4. The electronic bearer instrument of claim 1 wherein said electronic file is a video file.
5. The electronic bearer instrument of claim 1 wherein said electronic file does not contain personal identification information.
6. The electronic bearer instrument of claim 1 wherein said electronic file contains personal identification information.
7. The electronic bearer instrument of claim 1 wherein a cryptographic signature of a cryptographic hash of said electronic file is stored by a shopping or wagering management system and said cryptographic signature of said cryptographic hash acts as an indicator of authenticity.
8. The electronic bearer instrument of claim 1 wherein said claim validation attributes includes the credentials of more than one claimant.
9. The electronic bearer instrument of claim 8 wherein said electronic file may be possessed by each of said more than one claimant.
10. The electronic bearer instrument of claim 1 wherein said cryptographic key is a symmetric key.
11. The electronic bearer instrument of claim 10 wherein said symmetric key is encrypted with an asymmetric public key with a corresponding asymmetric private key known by said shopping or wagering management system.
12. The electronic bearer instrument of claim 11 wherein said encrypted symmetric key is included in said humanly undetectable second dataset.
13. An anonymous electronic bearer instrument comprising an electronic file transmittable in a lossless fashion, said electronic file including a final group of bytes derived from a first group of bytes and a second group of bytes, said second group of bytes being encrypted with a cryptographic key known only to a bearer instrument issuing authority, said second group of bytes containing wager information being selected by or for a claimant, said second group of bytes being encoded into said first group of bytes by changing one or more bits of one or more bytes of said first group of bytes resulting in the formation of said final group of bytes without significantly altering by comparison the auditory or visual presentation of the anonymous electronic bearer instrument represented by and between said first group of bytes and said final group of bytes, the resulting final electronic file containing said wager information being transferred from the issuing authority to the claimant, said second group of bytes being undetectable to the claimant of said anonymous electronic bearer instrument.
14. The electronic bearer instrument of claim 13 wherein said electronic file is an image file.
15. The electronic bearer instrument of claim 13 wherein said electronic file is an audio file.
16. The electronic bearer instrument of claim 13 wherein said electronic file is a video file.
17. The electronic bearer instrument of claim 13 wherein said electronic file does not contain personal identification information.
18. The electronic bearer instrument of claim 13 wherein said electronic file contains personal identification information.
19. The electronic bearer instrument of claim 13 wherein a cryptographic signature of a cryptographic hash of said electronic file is stored by a shopping or wager management system.
20. The electronic bearer instrument of claim 13 wherein said claim validation attributes includes the credentials of more than one claimant.
21. The electronic bearer instrument of claim 20 wherein said electronic file may be possessed by each of said more than one claimant.
22. The electronic bearer instrument of claim 13 wherein said cryptographic key is a symmetric key.
23. The electronic bearer instrument of claim 22 wherein said symmetric key is encrypted with an asymmetric public key with a corresponding asymmetric private key known by said shopping or wager management system.
24. The electronic bearer instrument of claim 23 wherein said encrypted symmetric key is included in said humanly undetectable second dataset.
