Detecting Lies through Mouse Movements
Interesting research: “The detection of faked identity using unexpected questions and mouse dynamics,” by Merulin Monaro, Luciano Gamberini, and Guiseppe Sartori.
Abstract: The detection of faked identities is a major problem in security. Current memory-detection techniques cannot be used as they require prior knowledge of the respondent’s true identity. Here, we report a novel technique for detecting faked identities based on the use of unexpected questions that may be used to check the respondent identity without any prior autobiographical information. While truth-tellers respond automatically to unexpected questions, liars have to “build” and verify their responses. This lack of automaticity is reflected in the mouse movements used to record the responses as well as in the number of errors. Responses to unexpected questions are compared to responses to expected and control questions (i.e., questions to which a liar also must respond truthfully). Parameters that encode mouse movement were analyzed using machine learning classifiers and the results indicate that the mouse trajectories and errors on unexpected questions efficiently distinguish liars from truth-tellers. Furthermore, we showed that liars may be identified also when they are responding truthfully. Unexpected questions combined with the analysis of mouse movement may efficiently spot participants with faked identities without the need for any prior information on the examinee.
Boing Boing post.

Oh great. More smoke and mirrors.
I’m sure that between all of: touch pads, left handed people, bad UX, slow internet, fat fingers, tired users, mentally ill people, people who use English as their second language, old or impaired people with worse motor control, people with parkinsons, blind people with screen readers, privacy savy users, confused users, annoyed users, USB and Bluetooth mouses and so on this will work JUST great when idiotic SV companies will start to use this as the sole mechanism deciding whether you’re a good user or literally Osama Bin Laden the Second that threatens their multi billion dollar website with their casual use of it.
We really need more pseudo science to join bite shapes, lie detectors, people reading and so on. If you don’t wanna play along and do everything we say – you’re evil.
And clearly we need more crappy bots to add to PayPal, Google services, YouTube, Facebook, et al. to automatically judge people as “liars” and destroy their accounts with no ability to appeal unless they have 100k followers on social media that make a stink over it.
I’m not impaired and I’m a human (although SV crowd loves to deny that with their shitty bots) and I often have problems with Google’s HORRIBLE image captcha on a certain website that loves to spam them every 5 minutes, shadow bans for ‘suspicious’ behavior (like linking to a better competitor website..) and such. Things such as putting a link in the comment or skipping bots are considered ‘suspicious’. But bots are everywhere on that website and pasting child porn, viruses and such, despite all this ‘advanced protection’.
It’s like the Futurama scene with more trains. Technology sucks, doesn’t stop the baddies, destroys normal users, burns resources needlessly – send in more shitty rushed technology.
