Problems solved by technology

In this implementation method, when analyzing the dark watermark, the key is to identify the positioning frame on the picture. Only by finding the positioning frame can the watermark information block be found. If the picture is dirty or missing, the positioning frame will be lost and the watermark information cannot be recognized.
In summary, the existing watermark adding and parsing technologies are inefficient or inaccurate

Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] In a typical configuration of the present application, the terminal, the device serving the network and the trusted party all include one or more processors (CPUs), input / output interfaces, network interfaces and memory.

[0035] Memory may include non-permanent storage in computer readable media, in the form of random access memory (RAM) and / or nonvolatile memory such as read only memory (ROM) or flash RAM. Memory is an example of computer readable media.

[0036] Computer-readable media, including both permanent and non-permanent, removable and non-removable media, can be implemented by any method or technology for storage of information. Information may be computer readable instructions, data structures, modules of a program, or other data. Examples of computer storage media include, but are not limited to, phase change memory (PRAM), static rando...

Abstract

The invention aims to provide a method and equipment for adding and analyzing an invisible watermark text. Compared with the prior art, the invisible watermark text corresponding to the watermark information text is determined by adjusting the color value corresponding to the watermark information text preset by the user, the invisible watermark text is invisible to naked eyes, and the invisible watermark text is drawn on the preset picture in a non-overlapping mode. The invisible watermark text is added to the preset picture, and the preset picture is fully paved with the invisible watermark text. In this way, watermark adding can be conveniently achieved.

Description

technical field [0001] This application relates to the technical field of software development, in particular to a technology for adding and analyzing invisible watermark text. Background technique [0002] At present, the existing dark watermarking technology can be roughly divided into two types: the first one is to achieve the effect of dark watermark by overlaying a transparent picture with watermark information on the original picture, but this implementation method needs to analyze the dark watermark information Sometimes, it is often necessary to use PS software to do complex processing on the picture to display the dark watermark information. This requires professionals who are proficient in using PS software to complete it. The personnel cost is high, and it is inconvenient to operate and low in efficiency. [0003] The second is to generate multiple graphic frames according to the watermark information, combine each graphic frame with multiple positioning frames to...
