Description

A kind of fingerprint control system

Technical field

The utility model belongs to the safety governor field, a kind of fingerprint control system of saying so more specifically.

Background technology

At present, security is the problem that many equipment and system will at first consider, although user one is to disliking quite that safety inspection mechanism gets involved in their work, the supvr still needs so a kind of formality and method of checking visit and use situation.The explicit identification user status if having no idea, you also can't be confirmed to be that user so, and what action he has operated actually.So the user can be compelled to carry out some cipher mechanisms or hardware flags with help us to go to follow the trail of to be actually who done a little what?

Existing a lot of equipment and system all are to use the method for " user ID+password " to carry out user's authentication and access control.In fact, this scheme is implying some problems.For example, password passes out of mind easily, is also stolen by others easily.And, if the user has forgotten his password, he just can not enter system, certainly reset password and restart work by the system manager, but will waste time like this, work efficiency to the user has certain influence, in case more seriously the system manager has forgotten oneself password, total system could be worked after perhaps only reinstalling.The investigation of appropriate authority shows that the problem that produces because forget Password has become one of FAQs of IT vendor's after sale service; Password is stolen then fearful thing especially by others, because the people who is ill intentioned may further steal company's confidential data, the name that may usurp others is done wrongful thing even extracted others huge deposit from bank, ATM terminal.In fact, stealing of password than being easier to, as long as the action of the keystroke when others is careful you and enters password before terminal just can be known your password, even can guess out your password by your birthday, age, name or some other information--many people use the birthday of oneself as password, password can also be separated brokenly one well-known, some military establishment's computer networks of the sensitive U.S. were once invaded by the hacker more than once, and the password that in fact hackers have separated brokenly a certain validated user of these computer networks begins.Although prevailing system prevents to usurp the password behavior by the mouth the present that requires the user in time to change them, this method has not only increased user's memory burden, can not tackle the problem at its root.
