The technology dubbed RNC (Recursive Cortical Network) by tech-firm is capable of mimicking eyes and brains in order to solve captchas. It may mean the need for more robust means of human verification.
The verification software known by many as only Captcha (Completely Automated Public Turing test to tell Computers and Humans Apart) is probably reaching its end. This new week, the technology-related firm, Vicarious, has created an AI that can pass Captcha tests with relative ease, thus, putting in danger the efficacy of human verification tools, such as CAPTCHA.
Vicarious developed this new technology with the aim to mimic the way our eyes and brain work. Called Recursive Cortical Network (RCN) this software is capable of successfully passing Turing tests, which would allow it to be recognized as a “human,” it replicates the way human eyes and brains work, by reading the text.
The method CAPTCHA uses to tests human and bots alike for verification relies on difficult to read, images and distorted letters which the user has to read, input their answer on a text box and then successfully pass the test. Naturally, this is something that poses no problem for the majority of humans, machines, however, bots find it difficult to pass these tests. CAPTCHA, as its name suggest, has the sole purpose of decanting whether the visitor is a
Neural networks alter themselves when presented with a problem, and change the way they interact in order to solve the problem. After neural networks have been “rearranged” they realize the correct pattern required to pass the test. It is important to note that Companies which use Captcha and derivative software, may have to change their method of human verification in the short future, as RCN may mean that bots are becoming advanced enough to pass these tests and disguise themselves as “humans.”
The tech-firm Vicarious’ newly released Recursive Cortical Network is able to crack reCaptchas, an advanced version of Captcha, with an accuracy rate exceeding 66 percent, notes the report. Other Captchas that it can beat are Yahoo at 57.4 percent, PayPal at 57.1 percent, and BotDetect, with a 64.4 percent. Vicarious’ experts have released a report where it reads that a Captcha is broken if it can be cracked 1 % of the time by a software or algorithm.
According to Turing’s test, a machine can be considered “intelligent” when it exhibits behavior “equivalent to, or indistinguishable from” that of a human. The main difference between RCN and other Captcha-solving AIs is that while these other AIs need to be fed millions of images and text in order to be trained, Recursive Cortical Network requires an astounding three hundred times less training data, greatly reducing time and investment on the training of the software.
According to Vicarious’ co-founder and lead author Dileep George “Captchas are becoming obsolete. RCN mimics the human brain, being able to learn using relatively few examples”.
