I'm trying to build application in c# to upload and search images in Google service. I have this link of a search.

I want to know what encoding this is:

  • But why are you using the front end to build upon? Why don't you use the image search API? This python package has more info: https://github.com/arrrlo/Google-Images-Search Also these answers: https://stackoverflow.com/questions/34035422/google-image-search-says-api-no-longer-available – Daantje Mar 27 '21 at 18:16

The part after "sbi:" looks like its is Base64 encoded: https://en.wikipedia.org/wiki/Base64

But if it is supposed to represent the raw bytes of the image then it is hard to confirm . When I decode the example string, that's what I get, raw binary bytes, not a string.

Note: assuming it is Base64 then the encoded text continues up-to-and-including the first equal-sign (=) that appears after the "sbi:" in the URL.

@modal_dialog

But if it is supposed to represent the raw bytes of the image then it is hard to confirm . When I decode the example string, that's what I get, raw binary bytes, not a string.

However - those binary bytes, the decoded string (taken from the url, up to and including the '='), do not seem to translate to a picture in any known format (not even when adding an extra '=' at the end of the to-be-decoded-string) ... so that seems to me it'd indicate it's not base64 encoding

[Edit:] @GeeSuth Since your question is related to building your own reverse image search service, you might wanna work with the initial Google Images search url:

https://www.google.com/searchbyimage?image_url=[location-of-img-to-search-from]

like eg. https://www.google.com/searchbyimage?image_url=https://european-made.com/wp-content/uploads/2019/11/logo-busnises.png1144.png
