Abstract

The invention relates to a password protection method based on position information. The method comprises an encryption step and a decryption step, and is characterized in that in the encryption step, the set password and the current position information are associated to generate decrypted information; and in the decryption step, after the entered password and the current position information are associated, the entered password is compared with the generated decrypted information in the encryption step so as to determine whether the decryption is carried out or not. After the technical scheme provided by the invention is adopted, the intensity of password protection can be effectively improved, the password length and memory difficulty are reduced, the hardware consumption is reduced and the number of the carried hardware is reduced.

Description

A kind of cipher code protection method of position-based information
Technical field
The present invention relates to the auxiliary cryptoguard of a kind of locating information and alarm method.
Background technology
Present cryptogram form is varied; the medium of applied cryptography is also diversified; comprise mobile phone used in everyday, bank card, safety cabinet, various accounts etc.; often because password loss or stolen; the loss brought also is very huge; how can better manage and protect encrypted message to be the thing that everybody is concerned about very much, and the cipher code protection method that password provider also needs a kind of fail safe more to increase, to improve the cryptoguard ability of user.At present conventional method only has the length of stronger cipher or number of combinations, interpolation subsidiary discriminant equipment as USB Key etc., the former increases the memory intensity of password user and the complexity of input password, the latter needs to carry other hardware facilities in addition, improves cost and become more to bother.
Summary of the invention
The object of this invention is to provide a kind of cipher code protection method of position-based information, when authentication password, obtain positional information from locating module simultaneously, and this positional information and input password are made comparisons with the positional information stored and password.If within the scope of setting, then tripper; If within the scope of setting, (even if password is correct) just can not unlock.Thus better protected.Because positional information can be set to the place of relative privacy or secret, so, even if the password of setting is relatively simple, positional information second protection also can be relied on to improve fail safe.
The invention provides a kind of cipher code protection method of position-based information, described method comprises encrypting step and decryption step, and the password of setting is associated generating solution confidential information with current location information by described encrypting step; The decryption information comparison generated with described encrypting step after the password of input associates with current location information by described decryption step, determines whether deciphering.
Further, incorrect number of times >=3 of described decryption step, output alarm information.
Further, the described current location information of decryption step is stated not within the scope of the described current location information of described encrypting step, output alarm information.
Further, described positional information is obtained by GLONASS (Global Navigation Satellite System).
Further, described positional information is obtained by map software.
After adopting technical scheme of the present invention, can effectively improve cryptoguard intensity, reduce Password Length and memory difficulty, hardware is carried in reduction hardware consumption and minimizing.
Accompanying drawing explanation
Fig. 1 is the encrypting step schematic flow sheet of the embodiment of the present invention;
Fig. 2 is the decryption step schematic flow sheet of the embodiment of the present invention.
Embodiment
In order to make object of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Accompanying drawing 1 is the encryption flow figure of the embodiment of the present invention.In the present embodiment, the password 101 that will be arranged by cipher input input, the input of password can be the interface for password input depending on operating system on mobile phone, also can be the PIN PAD etc. of safety cabinet.Obtain positional information 102, it can be the real-time position information obtained as the Big Dipper-2 satellite navigation system of GPS, GLONASS, Galileo and China by GPS (Global Position System), also can be by map software, manually carry out the positional information in the place selected above.Encrypted message and positional information are carried out associating generating solution confidential information 103 and storing, association can have two kinds of forms, the first: encrypted message is associated with positional information, the decryption information generating simple corresponding relation stores, and a password can arrange one or more positional information associated; The second: when positional information is unique, encrypt further password by positional information, the new decryption information generating a unique corresponding encrypted message and positional information stores.
Accompanying drawing 2 is deciphering flow charts of the embodiment of the present invention.In the present embodiment, after starting to decipher 201, obtain secret information 202, the input of password can be the interface for password input depending on operating system on mobile phone, also can be the PIN PAD etc. of safety cabinet.Obtaining positional information 203, can be the real-time position information obtained as the Big Dipper-2 satellite navigation system of GPS, GLONASS, Galileo and China by GPS (Global Position System).Encrypted message is associated 204 with positional information, and by decryption information comparison 205 that result and encrypting step produce, these two processes adopt consistent correlation form and comparison form, as, encrypting step adopts the first correlation form, then, decrypting process also adopts the first correlation form and contrast version.If comparing result is consistent, then, 206 are unlocked; If inconsistent, then judge whether to meet alert if 207, the condition of warning can be, continuously input encrypted message errors number >=3 time, or, the positional information obtained during decryption step, not within the scope of the positional information of encrypting step setting, meets alert if then output alarm information 208, specifies warning mailbox, mobile phone etc. as sending information to, warning message can comprise time of fire alarming, current location information, and follow-up consecutive tracking information, as information such as motion tracks; Do not meet alert if, then return 201, restart deciphering.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, all any amendments done within the spirit and principles in the present invention, equivalent replacement and improvement etc., all should be included within protection scope of the present invention.
