Embodiment 1

[0032] According to an embodiment of the present application, an embodiment of a method for displaying a watermark is provided. It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and, Although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

[0033] figure 1 is a flow chart of a watermark display method according to an embodiment of the present application, such as figure 1 As shown, the method includes the following steps:

[0034] Step S102, determining the watermark information to be added;

[0035] In the embodiment of the present application, the watermark information to be added may be acquired through the server, where the watermark information is encrypted information (that is, the ciphertext information described below). Specifica...

Embodiment 2

[0099] The embodiment of the present application also provides a watermark display device. The watermark display device is mainly used to implement the watermark display method provided in the above-mentioned content of the embodiment of the present application. The watermark display device provided in the embodiment of the present application will be described in detail below. introduce.

[0100] Image 6 is a schematic diagram of a watermark display device according to an embodiment of the present application, such as Image 6 As shown, the watermark display device mainly includes: a first determination unit 10, an acquisition unit 20 and a conversion display unit 30, wherein:

[0101] The first determining unit 10 is configured to determine the watermark information to be added;

[0102] The acquisition unit 20 is configured to acquire a preset coding method, which includes a display conversion relationship between different characters and dot-shaped coding graphics;

[...

Embodiment 3

[0116] see Figure 7 , the embodiment of the present application also provides a watermark display system 100, including: a processor 70, a memory 71, a bus 72 and a communication interface 73, the processor 70, the communication interface 73 and the memory 71 are connected through the bus 72; the processor 70 is used to execute executable modules, such as computer programs, stored in memory 71 .

Abstract

The invention provides a watermark display method, a device and a system and relates to the technical field of information media. The method comprises the following steps of determining the to-be-added watermark information; acquiring a preset coding mode, wherein the preset coding mode comprises the display conversion relation between different characters and dot-shaped coded graphs; according tothe preset coding mode, converting each character of the watermark information into a discrete point-shaped coded graph and displaying the discrete point-shaped coded graph in a transparent floatingwindow. The transparent floating window is a floating window which is arranged on a display screen in advance. The technical problem that the data safety is low due to poor invisibility of an existingwatermark technology is solved.

Description

technical field [0001] The present application relates to the technical field of information media, in particular to a watermark display method, device and system. Background technique [0002] With the rapid development of information digitization, the digitization of information media provides great convenience for information access, and also significantly improves the efficiency and accuracy of information expression. However, the subsequent side effect is that the security of these digital data files cannot be guaranteed during the transfer process, and it is easy to leak information by taking pictures, screenshots, printing, etc. [0003] In order to improve the security of data transfer, watermarking technology is introduced. Existing screen watermarking technologies are generally plaintext watermarks, which are easy for users to see and erase key information after seeing them, so that the added watermarks have no preventive effect. [0004] Although, the existing s...
