Abstract

A information-hidden mobile ticketing system, having a ticket purchasing device, an mobile ticket issuance management system, a embedded mobile ticket, a mobile communication device, and a ticket verification device. The user can purchase a mobile ticket from the mobile ticket issuance management system via the ticket purchasing device. Once the purchasing information is provided, the mobile ticket can be sent in the form of a message, a multi-medium message or other wireless form to a mobile communication device assigned by the purchaser. The information hiding method is used to embed the barcode representing the mobile ticket in a digital image. By a program specified by the mobile communication device, the digital image can be retrieved. Thereby, the risk of being decoded and stolen can be alleviated.

Claims

1. An information-hidden mobile ticketing system, including a purchasing device, a mobile ticket issuance management system, a embedded-mobile ticket, a mobile communication device, and a verification device, wherein the mobile ticket issuance management system is operative to generate a embedded mobile ticket when a purchase request by a purchaser is received by the purchasing device and send the embedded mobile ticket to the mobile communication device assigned by the purchaser.

2. The system of claim 1, wherein the mobile ticket issuance management system is operative to generate an mobile ticket and embed the mobile ticket in a digital image to form the embedded mobile ticket.

3. The system of claim 2, wherein the embedded mobile ticket includes any or any combination of text, symbol, image and barcode.

4. The system of claim 2, wherein the embedded mobile ticket is converted into a binary text string and embedded in the digital image via an information hiding technique.

5. The system of claim 4, wherein the binary text string is rearranged to replace a lowest bit of each pixel byte of the digital image.

6. The system of claim 1, wherein the embedded mobile ticket can be recovered only by a program specified by the mobile ticket issuance management system and downloaded to the mobile communication device.

7. The system of claim 6, wherein the specified program is operative to decode the embedded mobile ticket encoded by one or more than one information hiding techniques.

8. The system of claim 1, wherein the embedded mobile ticket can be sent to the mobile communication device in the form of a text message, a multi-medium message or other wireless transmission form.
