Description

Electronic Ticket System for Information Hiding

technical field

The present invention relates to an electronic coupon system for information hiding, in particular to an information hiding method for hiding electronic coupon information in general digital images, and the information needs to be decoded by a specific program on the mobile communication device , an electronic ticket system that hides the restored information of the electronic ticket.

Background technique

Since the contents of the electronic coupons are represented by electronic barcodes, alphanumeric symbols, or images, after the electronic coupons are downloaded to the mobile communication device at the user end, the electronic barcodes, images, or text and numeric symbols There is a risk of illegal copying or misappropriation by users.

Contents of the invention

The object of the present invention is to provide an electronic ticket system that hides information in general digital images through an information hiding method to reduce the risk of electronic ticket information being cracked and stolen.

The present invention is realized by adopting the following technical solutions: an information-hiding electronic ticket system, which includes a ticket purchasing device, an electronic ticket issuance management system, a hidden electronic ticket, a mobile communication device, and a ticket checking device; , for submitting the user’s ticket purchase information to the electronic ticket issuance management system; the electronic ticket issuance management system is used for generating electronic ticket information according to the ticket purchase information, and processing the electronic ticket information After the concealment process, a hidden electronic ticket is generated; and the hidden electronic ticket is transmitted to a designated mobile communication device through wireless transmission; the mobile communication device includes a specific program, and the specific program is used for the The hidden electronic ticket is decoded, and the information of the electronic ticket is restored and then sent to the ticket checking device; the ticket checking device is used to verify the validity of the received electronic ticket information.

Among them, the user purchases tickets from the electronic ticket issuance management system through the ticket purchase device, so that the electronic ticket issuance management system can transmit the hidden electronic ticket to the purchaser through SMS, multimedia message or other wireless transmission methods. The mobile communication device designated by the ticket holder, and uses the method of information hiding to hide the barcode image representing the electronic ticket into the general digital image, and requires a specific program on the mobile communication device to restore the original electronic ticket. Reduce the risk of electronic coupons being cracked and stolen.

Detailed ways

As shown in Figure 1, the schematic diagram of the structure of the information-hiding electronic ticket system provided by the present invention, the user purchases a ticket through the ticket purchasing device 1, and after purchasing the ticket, the electronic ticket issuing management system 2 will Ticket purchase information, generate electronic ticket information, and hide it in the general image to form a hidden electronic ticket 3, and then transmit the hidden electronic ticket 3 to the In the mobile communication device 4 designated by the ticket buyer; when the user wants to use the electronic ticket, the hidden electronic ticket can be restored to the original electronic ticket 5 by the specific program downloaded in advance on the mobile communication device 4, and handed over The legitimacy of the electronic ticket 5 is verified by the ticket checking device 6 .

As shown in Figure 2, the schematic diagram of the implementation of the hidden electronic ticket provided by the present invention, the electronic ticket issuance management system 2 generates the corresponding electronic ticket 5 according to the ticket purchase information of the user, and sends the electronic ticket 5 is converted into a binary bit string 7, and hidden into other digital images 8 by means of information hiding, such as hidden into a manufacturer's trademark image, and finally forms a hidden electronic ticket 3 containing electronic ticket information. The electronic coupon information may contain one of type data such as text, symbol, image, barcode or any combination thereof. In this embodiment, after the binary bit string 7 of the electronic ticket 5 is reorganized according to the arrangement rules established in advance, the lowest bit of each pixel byte of the digital image is reorganized into the electronic ticket after reorganization. 5; the digital image containing the hidden electronic ticket is sent to the designated mobile communication device 4 through the electronic ticket issuance management system 2, and can be downloaded from the user in advance and stored on the mobile communication device 4 The decoding program restores the original electronic ticket image; each decoding program can only perform restoration decoding for one or several information hiding methods, so as to ensure the security of the hidden electronic ticket 3 . In this embodiment, the decoding program is to first read the lowest bit of all pixel bytes of the hidden electronic ticket 3, and then perform anti-recombination according to the arrangement rules established in advance to obtain the original electronic ticket 5 binary bit string , and finally restored to the original e-ticket image.

Compared with the prior art, the electronic ticket system using information hiding provided by the present invention has the following advantages:

1. The present invention hides the electronic ticket information in the digital image by means of information hiding. The electronic ticket information requires a specific decoding program to restore the digital image to the original electronic ticket.

2. The present invention can use different information hiding methods to reduce the problem of hidden information being deciphered.
