BDAS (Background Draw a Secret) is an innovative password technology invented by Dr. Jeff Yan, a computer science lecturer, and Paul Dunphy, a PhD student.



It is meant to help in remembering passwords that most of us have to note in order not to forget, and in the same time this method makes the passwords more secure.
It is totally different than what we are used with, meaning that it's not about a line of numbers, letters and symbols.
This password type consists of a drawing that only the user who created it will know how it is made.


The user will draw a picture on the touchscreen of its PDA for example, and the key points of this unique password will be the image itself, but also the number of pen strokes used, the image’s starting point, and the most important, the order in which it was drawn.

This is what the researchers at Newcastle University are trying to develop, a Graphical Password.
One of the major benefits of this innovation would be for people with language difficulties like dyslexia.
This is a learning disability that can be recognized from the writing, reading and spelling difficulties.

As the researchers say, this type of passwords is almost impossible to crack, and becomes really impossible since the drawing is very complex.
The add-on software for Smartphones will probably be used very soon.

This is what Dr Jeff Yan said:
"Many people find it difficult to remember a password so choose words that are easy to remember and therefore more susceptible to hackers. Most of us have forgotten a pin number or a password at least once, which is why we tend to make them so easy to guess. However, the human mind has a much greater capacity for remembering images, and it's certainly true that a picture is worth a thousand words in this instance."
