Methods and devices of generating and decoding image streams with respective verification data

Abstract

A method and device of generating an image stream with verification data are provided. The method includes the following steps. First, determine at least one pixel in a first image according to a first encoding parameter. Then, generate a timing data sequence associated with information about the correlation between the verification data and time points according to a second encoding parameter and the verification data. Next, modify a pixel value of the at least one pixel in the first image to generate a second image according to the verification data corresponding to one of the time points in the timing data sequence. Lastly, generate the image stream including the second image.

Description

technical field [0001] The present invention relates to a method and device for generating and decoding video streams with verification data. Background technique [0002] With the prevalence of smart phones and the popularization of the Internet, the development of tickets has rapidly spread from the traditional paper form to electronic tickets in recent years. However, as the number of e-tickets grows, the first problem to be faced is the verification of e-ticket cancellation. [0003] Currently common electronic tickets are presented in the form of Quick Response Code (QR Code), but consumers need to provide an additional set of passwords to have a security mechanism, so the security mechanism is not perfect. And as the types and quantities of electronic tickets increase, it will cause great inconvenience to consumers. On the other hand, for stores, the current Point of Sale (POS) system does not have a standard way of writing off electronic tickets. It is labor-intens...

However, as the number of e-tickets grows, the first problem to be faced is the verification of e-ticket verification

[0003] At present, common electronic coupons are presented in the form of Quick Response Code (QR Code), but consumers need to provide an additional set of passwords to have a security mechanism, so the security mechanism is not perfect

And as the types and quantities of electronic tickets increase, it will cause great inconvenience to consumers.

On the other hand, for stores, the current Point of Sale (POS) system does not have a standard way of writing off electronic tickets. Accepting orders manually, and then inputting the consumption data into the system after the fact, is not only labor-intensive but also error-prone
