Problems solved by technology

[0016] In the fourth type of technology, the recognition process of the app corresponding to the hidden picture or hidden code technology is to first take a picture, and then send the static picture back to the background for comparison with the networked background. However, this recognition method It is also easy to be counterfeited by counterfeit APPs through counterfeit background replacement of static images, overlapping of preset images inside counterfeit apps, and replacement of preset images inside counterfeit apps.

Embodiment 1

[0050] Through this embodiment, it is possible to understand the general process and difficulty of detecting a hidden image by a smart phone or a smart mobile device. Video is a series of discrete images with high acquisition frequency, so that visual persistence can be used to achieve visual continuity. Each discrete image is called a frame. Usually, the analytical interpretation of hidden images is done on a frame-by-frame basis.

[0051] The detection and decryption of the base map have specific requirements on the image quality of the captured or intercepted original image. Depending on the specific method of collecting pictures, the requirements are slightly different, but there are higher requirements for the focus and magnification of the shooting system.

[0052] Due to its high anti-counterfeiting and anti-copying functions, the technology of hiding images through the modulation of dot structure (for example: SI technology of Graphics Security System company, ICI tec...

Embodiment 2

[0083] In this embodiment, the method for enhancing the liveness and authenticity of the hidden image detected by the smart mobile device is a synchronous display method for image switching or insertion, such as Figure 4 As shown, the first row in the figure shows a series of graph frames of the continuous graph video; the second row shows the corresponding decrypted hidden basemap, for example, only at frame numbers 3, 6, 7, and 11 The base image is obtained on the above; the third line shows an image display method, that is, switching the original table image frame with the decrypted base image on the original table image frame from which the base image is decrypted.

[0084] Due to the limited number of frames for deciphering the base map, it takes a short time to display and is fleeting, and may not leave a persistent visual effect. Figure 4 The fourth line in the shows a method to enhance the visual persistence effect of the base map, which is to extend the display time...

Embodiment 3

[0090] This embodiment provides another method for enhancing the liveness and authenticity of the hidden image detected by the smart mobile device, that is, a method for synchronously displaying the base image and the table image video. Like embodiment 2, the live video of the chart captured by the camera of the smart phone or smart mobile device in real time is continuous, but the base map decrypted by selecting a specific frame of the chart through the algorithm may be discontinuous and non-linear. In this embodiment, the displayed spatial region is divided into several parts, or several windows are directly displayed, and the live table and graph and one or multiple synchronized decrypted base maps are displayed synchronously in multiple windows, such as Figure 5 shown.

[0091] Different from Embodiment 2, a certain part of the area or a certain sub-window shows the continuous video of the table chart captured in real time by the camera of a complete smart phone or smart ...

Abstract

The invention provides a method for enhancing liveness and authenticity of detecting hidden images through utilization of a smart mobile device and relates to the technical field of smart phone or smart mobile device information identification and fake resistance. According to the method, after a smart phone or the smart mobile device decrypts base images hidden in frame pages corresponding to a live video, the surface image live video and at least part of hidden base images decrypted from the frame pages corresponding to the live video are displayed synchronously. According to the method, thesurface image live video and the detected base images corresponding to the surface image live video can be displayed synchronously, and dynamic comparison is formed, so the timeliness, authenticity,transparency, certainty and liveness of detecting or reading the base images are greatly improved, the possibility that printed matters comprising the hidden images and reading APPs are counterfeitedis greatly reduced, and APP image scanning, code scanning anti-fake source tracing and goods-fleeing resistant functions of the smart phone or the smart mobile device are ensured well.

Description

technical field [0001] The invention relates to the technical field of information identification and anti-counterfeiting of smart phones or smart mobile devices, in particular to a method for enhancing the liveness and authenticity of hidden images detected by smart mobile devices. Background technique [0002] The technique of hiding other images or information within printed diagrams has a long history. With the digital development of printing, more and more technical methods for hiding images or information have been developed and applied, the most widely used in the field of anti-counterfeiting. The most representative high-fidelity image collection technologies include Graphics Security System's SI technology, JURA's ICI technology, and the high-fidelity image collection digital hanging network technology with patent application numbers 201610519053.3 and 201610518384.5. [0003] The actual displayed image that the observer can see is called the surface image; the ima...
