Show HN: PDFs that are readable by human eyes only
69 by viggity | 74 comments on Hacker News.
Hi, OP here. A friend was involved in a custody battle and was afraid his ex was going to leak all of his discovery documents on the internet and he asked if there was something I could do to make it harder for bots/crawlers to find sensitive information. Originally I was going to turn all of his docs to image based PDFs, but those get large fast and are easy to OCR. So I found a post musing about altering fonts/glyphs so that it looks like english, but the actual character being seen by the pdf reader is a non-english character. As such, when you try to OCR these files, it doesn't see any images and can't convert it. I figured it had some potential uses and maybe you fine folks can identify other use cases. I'll be monitoring this post most of the day.

North Korea test fires two missiles month before deadline for US to respond on talks

Image
North Korea fired two "unidentified projectiles" on Thursday, Seoul said, as nuclear talks between Pyongyang and Washington remain deadlocked. The projectiles were fired eastwards from South Hamgyong province and came down in the Sea of Japan, also known as the East Sea, South Korea's Joint Chiefs of Staff (JCS) said. They added that the launch, the latest in a series by Pyongyang, was carried out at 16:59 pm local time - or the early hours on the east coast of the United States, during Thanksgiving, one of the country's biggest annual holidays. It was also one day short of the two-year anniversary of the North's first test of its Hwasong-15 intercontinental ballistic missile, which analysts say is capable of reaching the entire US mainland. Pyongyang is banned from firing ballistic missiles under UN Security Council resolutions, and Prime Minister Shinzo Abe said that Thursday's launch was the latest in a series of violations.  "North Korea's repeate...
