Since hash functions are also deterministic (meaning that the same input produces the same output), comparing two password hashes (the stored one and the hash of the password provided by a user) is almost as good as comparing the real passwords. Hash functions are designed to be one-way, meaning that it is very difficult to determine the input that produces a given output. Instead, authentication systems store a password hash, which is the result of sending the password - and a random value called a salt - through a hash function. This would make it far too easy for a hacker or a malicious insider to gain access to all of the user accounts on the system. I earned a BS in journalism from West Virginia University, and started my career writing for newspapers in New Jersey, Pennsylvania, and West Virginia.A well-designed password-based authentication system doesn’t store a user’s actual password. Prior to joining PCMag, I was a reporter for SC Magazine, focusing on hackers and computer security. I'm also a yoga instructor, and have been actively teaching group and private classes for nearly a decade.īefore becoming an analyst in 2020, I spent eight years as a reporter covering consumer tech news. I unbox, set up, test, and review a wide range of consumer tech products from my home in Florida, often with the help of my pitbull Bradley. I'm PCMag's expert on fitness and smart home technology, and I've written more than 6,000 articles and reviews in the 10-plus years I've been here. The hub advises victims to take screenshots of revenge porn before taking steps to have it removed. The company has also launched a support hub for victims called " Not Without My Consent (Opens in a new window)" offering instructions on how to report revenge porn shared on Facebook ( use this form (Opens in a new window)) and other websites. Over the coming months, Facebook plans to expand that pilot "so more people can benefit from this option in an emergency," Davis wrote. Facebook then uses photo hashing technology to prevent those photos from being uploaded to its platforms in the future. The renewed effort comes after Facebook in 2017 launched a pilot program in Australia that lets people preemptively send nudes before angry exes post them. "This means we can find this content before anyone reports it, which is important for two reasons: often victims are afraid of retribution so they are reluctant to report the content themselves or are unaware the content has been shared." "By using machine learning and artificial intelligence, we can now proactively detect near nude images or videos that are shared without permission on Facebook and Instagram," Facebook Global Head of Safety Antigone Davis wrote in a Friday blog post (Opens in a new window).
