Digital-watermark-based implicit two-dimensional code

Abstract

A digital-watermark-based implicit two-dimensional code includes a user side and a network side. The user side includes a user side application program which calls photographing or image pickup equipment according to the need, so as to fulfill a function of shooting a picture; and the user side application program includes a watermark extraction module, a request module and an information receiving module. The network side includes a resource access server, and a network side application program includes a watermark embedding module used for using resource access information as a watermark to be embedded in a background image, a resource access database used for storing description information, an access processing module used for receiving an access request of the user side, searching the resource access database, and feeding a result back to the user side. The advantage is that through a digital-watermark-based implicit two-dimensional code system, a novel resource access method is realized. All functions of a two-dimensional code can be realized, and the two-dimensional code becomes implicit, and does not cause visual influence to an image.

Description

technical field [0001] The invention relates to the field of resource access, and relates to a method for resource access through an implicit two-dimensional code technology based on a digital watermark. Background technique [0002] With the continuous development of information technology, it is more and more convenient for people to obtain information through the network. [0003] The traditional resource access method requires the visitor to first input the network address of the resource into the address bar of the browser, and then click the resource link provided by the web page to access more resources. This access method requires the visitor to remember the network address of the resource, which has high requirements for the visitor. [0004] Now with the rapid development of smart mobile terminals, some more convenient resource access methods have emerged. Among them, the most representative and the most widely used is the two-dimensional code technology. The so...

Problems solved by technology

[0005] But the two-dimensional code also has some disadvantages: (1) The appearance of the two-dimensional code is a black and white frame, which lacks aesthetic feeling, and its existence destroys the overall integrity of its environment

For example, in a beautifully printed advertisement, if a QR code is placed somewhere, the beauty of the entire advertisement will be reduced.

(2) Secondly, in order to improve the recognition rate, the placement of two-dimensional codes is subject to certain restrictions. For example, it cannot usually be used for outdoor billboards, otherwise it will be difficult for users to use smart mobile terminals due to the long distance or excessive angle.
