The security company NuCaptcha is to accommodate digital advertising system in a CAPTCHA (routines for verification of identity and authenticity) that uses video and makes more difficult the use of programs that seek to pierce this protection.

Typically, the CAPTCHA box displays a static image with two words written with characters whose reading is hampered by noises.

When we began to be used on the Internet, it was difficult for OCR software (responsible for interpreting traces and interpret them as if they were characters). However, currently, these programs do not find it more difficult to perform this operation.

To prevent OCRs could easily decipher the contents of CAPTCHA codes were introduced so many noises in the composition of characters that its reading became impossible even for people.

The technology developed by NuCaptcha brings a new element to halt the activity of programs crackers. In place of traditional static image, the contents of the boxes are displayed in the form of a video track within the frame. The fact that the contents are in motion makes the programs to solve CAPTCHA static obsolete.

Another advantage is that in video form there is less need for noise in the text, making the CAPTCHA something more sympathetic in the eyes of users.
