Fun experiment: if you see a greentext on reddit, try typing out one of the sentences word for word, and pasting it into the reddit search bar. It will show you one post, and that will be the post you copied that sentence from.
If reddit has the ability to mass OCR and index every image for searching, then almost every other platform has as well. So things like screenshotting text and posting it will still get indexed and linked to your account. Insta algos will probably derank your account if you have words like Palestine, Gaza, etc. even if you try to bypass that by screenshotting them instead of typing them.
Another aspect of this is sending images by WhatsApp, only doubly so, because those images end up in the gallery, and most phones nowadays automatically OCR them as well. This increases your attack vector, depending on your threat model, I guess.
It does make it harder depending on the platform and what you’re trying to accomplish but yes, OCR has been near perfect for well over a decade now, it’s basically a commodity software at this point. Unless you’re encoding your image like a captcha or using some riddle or something as extremely basic encryption, image posts with text and text posts are basically the same thing.
There are still use cases for text as images but “getting around platform filters” is rarely one of them unless you’re coupling it with other methods as well
The value of ideas like two factor authentication comes from a baseline assumption that all credentials are comprised.
During the Russian revolution, the Bolshevik party assumed all their meetings were infiltrated and compromised.
It might be time to take a personal security stance that relies on multi factor authentication and review, compliance & recovery just like big organizations do.
return to wacky calligraphic fonts, OCR shits itself with those
Yeah, if my phone lets me copy text from images as a built-in feature, I can’t imagine a major platform lacking that ability
This week’s cypher below
Gaza = family
Genocide = thanksgiving
IDF piss babies = pumpkin pie
The Thanksgiving being carried out by the pumpkin pie against my family is a crime against humanity.
Heck, I can search my phone gallery images for text. I didn’t even realize that was an option till earlier this year. Still haven’t looked to see if it’s being done locally or if they’ve been scanning stuff in the cloud.
Idk whether it goes through the same channels as the search feature, but my phone’s OCR ‘Select’ feature works in airplane mode so I guess it must not be very resource intensive
It is not particularly resource intensive. You can use Tesseract locally on a modern PC and it will OCR text faster than you can snap your fingers.
My guess would be that the scanning is done at the time of creation and then the text and image description is store in a db. But yeah, one of the first tensorflow android examples they released was for local object detection and that was almost ten years ago, I think. I’m sure it’s advanced quite a bit. We’ll have narc LLMs installed soon enough.
Probably so. I’d assume that tech companies would want an opportunity to scan your saved pictures for ad-profile data, but also I’m surprised that a different OCR feature works locally and near-instantly
Specifically, my phone running Android 14 has a ‘Select’ feature that you can activate when switching between active apps, and so far it’s been able to copy optically from any app that doesn’t privacy-block its contents from appearing in the app switcher
Some googling reveals that, in my case, Samsung has it built in their OneUI and it doesn’t have an option to be turned off. Good to know.
