Embodiment
Referring to accompanying drawing, comprise finger print acquisition module 1, central processing module 2, terminal module 3 and power module 4 in the structure of a specific embodiment of the utility model, central processing module 2 receives and carries out information output from the input information of finger print acquisition module 1 and to terminal module 3, and power module 4 is system's supply of electrical energy; Finger print acquisition module 1 is the capacitance type fingerprint acquisition module, and terminal module 3 is safety electromagnetic lock or digital safety switch, and power module 4 is dry cell.Input panel 11 is set on the finger print acquisition module 1, four fingerprints is set on this input panel 11 keys in point 12; 6, according to claim 1 and 2 or the many fingerprint encryption systems of 3 digitizing, it is characterized in that: also be provided with password replacement reset key 13 on the input panel 11.
Principle of work of the present utility model is: be provided with four fingerprints at control panel and key in point, the user chooses n root finger (n＜=4) at random, and the sequencing of the sequencing of the finger of arrangement at random key entry and key entry position (finger and key entry position all allow repetition), finish thus encryption.In the time of later on deciphering, need to repeat above step and just can finish.During Modify password, clear switch be need to press, new password and preservation then keyed in.
This product is equivalent to fingerprint identification technology and array combined ciphering are combined togather.Can greatly improve security performance like this.Want to decode, except the fingerprint that will obtain owner, also need to know the sequencing of finger arrangement when it is keyed in, key in the sequencing of position, and both multiplicity.I think that this is real extremely difficult for the code breaker! And for the user, can worry perhaps that password is too loaded down with trivial details and cause forgeing that this needn't worry that fully the password difficulty of this product is adjustable.The user can make by oneself and use finger quantity, keys in some quantity, and key entry order, multiplicity, with convenient memory.Exactly because capable of regulating difficulty, this product just can satisfy users' different demands.For the ordinary family user, low level only need to be set maintain secrecy and get final product, and for company or individual that needs are preserved valuables or preserved classified papers, then can arrange high-level secret.
We are connected finger print acquisition module (namely keying in a little) with central processing unit, be connected at the following setting pressure sensing device of each acquisition module and with central processing unit again.Between acquisition module and processor, switch is installed.When we encrypted, finger was pressed the key entry point, keyed in the fingerprint collecting of naming a person for a particular job and got off, and the pressure-sensing device senses pressure signal below simultaneously should key entry point also passes to processor.Inner at processor, the finger print information of key entry and key entry dot position information are numbered in the lump to be stored.In the time of deciphering, when we keyed in fingerprint, processor can carry out the fingerprint analysis contrast on the one hand, saw whether the key entry fingerprint is correct, examines on the other hand the key entry dot position information.After both comparing successfully, processor can send instruction, the running of control external circuits.In the time of need to again encrypting, can recover as long as press reset key.And whenever inputing by mistake once, processor will be accepted rub-out signal one time.When rub-out signal accumulative total reached 3 times, central processing unit will be controlled safety switch and disconnect, and finger print acquisition module just disconnects 20 minutes with central processing unit like this, and encryption device is equivalent to locked, can't key in fingerprint and open.After 20, safety switch is with auto-closing.During Modify password, press clear switch, be equivalent to empty the data that are stored in processor inside, key feeding cipher more at this moment, processor is record data again.For preventing from pointing the inconvenience that breakage brings, this equipment can also store for future use password in order to use during the several finger of None-identified.
Principle is as follows:
Ciphering process:
Key in fingerprint (two covers are so that for subsequent use)---fingerprint is carried out digitized processing---ordering and storage fingerprint and key in the position;
Decrypting process:
---fingerprint is carried out digitized processing---contrast one by one fingerprint and the key in the position---password cracking of keying in fingerprint;
Safety precautions:
Key in fingerprint or positional fault and---contrast unsuccessfully that---processor reception rub-out signal reaches that---safety switch reconnects and recovers normal in safety switch disconnection---timer is started working and kept 20 minutes---three times;
Modify password:
---zero clearing of processor internal reservoir data---is keyed in new password---and is preserved complete operation to press reset key.
Foregoing description only proposes as the enforceable technical scheme of the utility model, not as the Single restriction condition to its technical scheme itself.
