Scientists at Rutgers (Rutgers), State University of New Jersey, say they are six months will create a code that will protect the passwords from the discovery. Despite the fact that until now the passwords are a good way to limit access to a computer or website, this security system has many disadvantages. Main, as often happens, is the human factor. People use passwords that are too easy to guess. One research firm says that people can guess the password of someone else's e-mail in 17% of cases, where spouses guess the password of the half in 33% of cases. Another study showed that it is often used as a password, the names of children (23%), spouses (19%) or date of birth (12%). Another problem is that people tend to forget their passwords and access to justice in a "secret question", which is also often easy to guess.

Computers & Income from Rutgers Danfeng Yao said that the current massive security issues is not very safe, and that it is working on a better system. Yao led a team of scientists, developing an approach to security, taking into account "activity". In other words, the computer may ask the user for some information related to recent data, for example, ask, "When is the last time you sent an email?" Site type Amazon may ask the user name of the last book he bought, and the bank could ask about the amount of last payment that was made by the client.

The advantage of such a system that answers to these questions, in contrast to the days of birth, addresses, names of classmates, etc., can not be detected in the profiles of sites, blogs or public forums. Instead, the dynamic issues, invented by Yao, used the answers that are constantly changing. She said that recall such data is usually not a problem, that showed the trial testing issues based on the type of activity conducted by a group of students.
