|Description||Well, the thing is, I'm playing a Japanese game recently. This game can share your favorite homemade characters through PNG "character card"|
In fact, the role information is attached to the end of the PNG file. The whole "role card" is a small archive file that stores the character's info
I wonder if ghost can be shared like this?
It is feasible to attach a zip file after a PNG file. You can easily open the file in the form of a compressed package by changing the suffix name to zip. Therefore, if we specify a special file suffix, such as ".nar.png", or check the additional content every time SSP processes the image file, we can express the NAR in the form of a picture
Maybe we can be more aggressive and save ghost's homeurl to the picture, so that the volume is smaller and the function is not affected

There is a large company called Alibaba in China, and not long ago an employee of the company leaked a screenshot of his computer and announced to the public that the company was working overtime illegally, and that all personal information had been mosaicked.
The company then fired the employee
The technology used by the company is called "invisible watermarking", where you can put some information in the pixels of an image, but the image will look no different to the human eye
You know, it's too easy to put a few bytes of employee information in a few hundred kilobytes, but I think we could also put ghost information in a png, like homeurl
Appending data to the end of the file would work, but it's likely to disappear after the chat software has processed it, and I suppose we could use a low-profile version of the "invisible watermark" in this scenario if it was technically feasible, you know, just not as resistant to interference
Although it has nothing to do with ukagaka, I would like to know.
1. can this "invisible watermark" be identified or removed or made unrecognisable?
2. Is Alibaba, the company, still working illegally overtime?
3. what is the follow-up situation of the employee?
Yes I think it would be cool if ssp supported the installation of nar in png or other image format, nar authors could make nice "covers" for their nar files and this would also provide a preview of the nar content on some software
And personally I think it's very much like the "summon a genie from a card" scenario, yeah, cool
But personally I probably wouldn't want special suffixes like .nar.png, it seems a bit outrageous
I think what ssp could do is to do a "legal nar" check every time a file is dragged in, which would be aesthetically pleasing and not have much of a performance impact
As for the "invisible watermark", it's a good idea, but I don't think it's that easy to implement, and although it's a viable technique, it's a bit of a "laser gun to a mosquito" in this case
