Abstract
The invention provides an unlocking method and an unlocking system based on PDA (personal digital assistant) and fingerprint. The method is characterized by comprising the following steps of: prerecording fingerprint, generating random data by a center computer, transmitting to a handheld terminal PDA, transmitting the random data into a lock controller to be verified after the fingerprint verification is carried out by the handheld terminal PDA, returning the data back to the handheld terminal PDA to operate in an encryption way after the verification is successful, transmitting the generated encrypted data into the lock controller to be deciphered, starting a lock after the deciphering is successful, and otherwise alarming and promoting to go through an unlocking procedure again. The system consists of the center computer, the handheld terminal PDA and the lock controller with a short-distance communication interface. According to the invention, the password does not need to be remembered, and the phenomenon that the password is lost or stolen can be avoided, so that the safety protection level can be greatly improved.
Description
Technical field
The present invention relates to a kind of security and guard technology, the open method of the lockset of the high-grade security protection unit such as especially a kind of national treasury, rifle storehouse, specifically a kind of method for unlocking based on hand-held terminal device PDA and fingerprint identification technology.
Background technology
At present, national treasury and armament depot, ATM (Automatic Teller Machine), proof box, safety cabinet, classified document cabinet etc. are all the very high equipment of security requirement, are emphasis security protection parts.As this type of security protection emphasis most critical be door lock, door lock is generally coded lock, traditional is take mechanical code lock as main, the modern times are take electronic cipher as main, also have to adopt dynamic password.No matter but use which kind of password, a GPRS password just can enter Ku Nei or open the cabinet door.Especially the fixed password lock, as long as remembered password, hold yard people and just be easy to enter the storehouse, especially relieve a sentry when operating personnel leave office, when deliberately the situation such as leakages causes the password leakage, will cause very serious robber to rob accident, to this, the solution that there is no at present.
Summary of the invention
The objective of the invention is for existing coded lock poor safety performance, holding yard people is easy to enter in the high storehouse of security grade and is engaged in delinquent problem, authentication is main through repeatedly finger print identifying and random cipher to invent a kind of need, even password loss can not affect safe method for unlocking and system based on hand-held terminal device PDA and fingerprint identification technology yet.
One of technical scheme of the present invention is:
A kind of method for unlocking based on hand-held terminal device PDA and fingerprint identification technology is characterized in that, said method comprising the steps of:
At first, in advance in the finger print information typing control center computing machine with each unlock staff, and generate fingerprint characteristic Template Information corresponding to unlock staff;
Secondly, when the arrangement personnel unblank, computer system produces one group of random number R ND1 that the unlock staff is corresponding, simultaneously, computer system fingerprint characteristic Template Information that described unlock staff is corresponding and the random number R ND1 corresponding with described unlock staff and the unlock staff lock controller that allows to open transfers in hand-held terminal device PDA by wire communication mode or communication for No. ID;
The 3rd, after the unlock staff holds described hand-held terminal device PDA and arrives the scene of unblanking, carry out fingerprint authentication on described hand-held terminal device PDA, unlock staff's fingerprint matching success as appointment in unlock staff's fingerprint and hand-held terminal device PDA, described hand-held terminal device PDA transfers in lock controller by wire communication mode or the communication random number R ND1 that the unlock staff is corresponding, also can be input in lock controller by the manual random number R ND1 that the unlock staff is corresponding of operating personnel;
The 4th, after lock controller receives random number R ND1 corresponding to described unlock staff, namely produce one group of verification msg RND2 that comprises No. ID, lock controller and formed by random number that lock controller produces, and transfer in described hand-held terminal device PDA by wire communication mode or communication, also can described verification msg RND2 be input in described hand-held terminal device PDA by operating personnel are manual;
The 5th, after hand-held terminal device PDA receives described verification msg RND2, generate a group encryption data ENC according to the encryption rule of being arranged in advance by control center's computing machine and lock controller, again this enciphered data ENC is transferred to lock controller by wire communication mode or communication, also can described enciphered data ENC be input in lock controller by operating personnel are manual;
At last, lock controller receives after described enciphered data ENC according to the encryption rule of making an appointment with the control center computing machine again and carries out the accordance computing, if operation result is consistent with prior agreement, lock controller is unblanked.
The generation of described enciphered data ENC can transfer to hand-held terminal device PDA in advance by control center's computing machine after the encryption rule of agreement generates described enciphered data ENC in advance with lock controller; Also can verification msg RND2 be transferred to control center's computing machine by hand-held terminal device PDA, transfer to hand-held terminal device PDA by control center's computing machine after the encryption rule of agreement generates described enciphered data ENC in advance with lock controller;
Described wire communication mode is short distance wire communication mode or remote wire communication mode.
Described communication is short-distance wireless communication mode or remote-wireless communication mode.
Two of technical scheme of the present invention is:
A kind of unlocking system based on hand-held terminal device PDA and fingerprint identification technology is characterized in that it comprises:
One control center's computing machine 1, described control center computing machine 1 be with communication module A, be used for described hand-held terminal device PDA2 with communication module B carry out communication; Pre-record in described control center computing machine 1 finger print information that possesses the qualification personnel that unblank and can will unblank the time finger print information and generation at random one group of the unlock staff of actual typing send by described communication module A with random number R ND1 corresponding to unlock staff;
The one hand-held terminal device PDA2 with the fingerprint input function, described hand-held terminal device PDA2 has the fingerprint authentication function, need to carry out when the unlock staff unblanks just carrying out unlock operation after fingerprint authentication; Described hand-held terminal device PDA2 is with communication module B and communication module C, communication module B be used for control center computing machine 1 with communication module A carry out communication, communication module C be used for lock controller with communication module D carry out communication;
One lock controller 3, this lock controller 3 is with communication module D and have corresponding computing and discrimination function, is used for according to the unlatching of differentiating the output control lockset.
Beneficial effect of the present invention:
The present invention security unit that attaches most importance to provides new security protection measure, can guarantee grasp the fixed password personnel leave office or reveal after still can realize good security protection, can remove the unlock staff simultaneously from and memorize complicated code data.Both realized the fixed code with the people, and can guarantee again not affect the unlatching of lockset after personnel change.
The inventive method is simple and clear, and randomness is good, cracks probability little, and can not divulge a secret, and is safe and reliable.
