Fig. 1 is the safe transmission method step schematic diagram of a kind of sensitive information Anti-theft of the present invention, as a specific embodiment of the present invention, as shown in Figure 1, the invention provides a kind of safe transmission method of sensitive information Anti-theft, comprising:
Step 1 client generates the randomly ordered rule of all keypad characters according to the first algorithm, by keypad character by randomly ordered regularly arranged;
Step 2 server generating identification table, stores all keypad characters and identifies one to one with keypad character in label table;
Step 3 client obtains keypad character to be transmitted according to the sensitive information that user inputs, and identifies one to one to server acquisition with keypad character to be transmitted, generating identification information;
Step 4 encrypted identification information generates the first ciphertext, and is sent to server;
Step 5 server receives and deciphers the first ciphertext, obtains identification information, parses mark according to identification information, is inquired about and extracts the keypad character corresponding with mark, obtain the sensitive information of user's input by label table.
Sensitive information comprises bank card account number, password etc.
The invention provides a kind of safe transmission method of sensitive information Anti-theft, first by randomly ordered regularly arranged keypad character, prevent wooden horse from stealing sensitive information by the input point recording screen, again by by sensitive information encrypted transmission, keyboard hook, data decryptor, data cutout equivalent risk are effectively taken precautions against.
Concrete, in step 1, client generates the randomly ordered rule of all keypad characters according to the first algorithm, by keypad character by randomly ordered regularly arranged.The present invention first algorithm is SOTP algorithm, and binding time information and device id (such as mobile phone IMEI code) generate randomly ordered rule for dynamic factor, according to randomly ordered regularly arranged keypad character, are shown to user by client.Below with the soft keyboard citing on mobile phone A PP, introduce the randomly ordered rule of SOTP algorithm generated keyboard character in detail.
Keypad character comprises numerical character and alphabetic character, and keypad character shows with symbol picture.
For array:
1, get hardware ID, mobile phone IMEI code in the present embodiment, can be got.
2, get current time information T, unit is millisecond.
3, E is calculated
k(H (ID)+E
k(T)).
First by the safe unidirectional hash function H (ID) that hash algorithm computing hardware ID calculates, by cryptographic algorithm encryption times information E
k, then encrypt H (ID) and E (T)
k(T), namely E is obtained
k(H (ID)+E
k(T)), result is converted into the number r1 between 0-9;
4, the several a1 being arranged in r1 position in 0-9 ordered series of numbers (10 numerals in keypad character) are got;
5,0-9 ordered series of numbers removes a1, surplus 9 numbers, and continue the 2nd step, result transfers the several r2 between 0-8 to, and then peek row (9 number) is arranged in the number of r2 position, continues with this.
Can fetch squence: a1a2a3 ...
Citing, suppose that the sequence that above-mentioned steps obtains is digital random sequence: 412357698, then represent, the 4th numeric keypad character puts the 1st, and the 1st numeric keypad character puts the 2nd ..., the 8th numeric keypad character puts the 9th.Thus by the keypad character random alignment of numeral.
For alphanumeric arrangement: same to array, first get the number between 0-25, then get 26 times successively, such as alphabetical random series: 23 2 13 14 53 10 .... then represent that the 23rd alphabetic keypad character puts the 1st, the 2nd alphabetic keypad character picture puts the 2nd ..., therefore not to repeat here.
In the present invention, keypad character is symbol picture, is obtained by server, dynamically produces and when time effectively, and each character picture arrangement position when using shown by keypad character is different, effectively prevents sensitive information to be stolen.
Server generating identification table in step 2, stores all keypad characters and identifies one to one with keypad character in label table.During each use, server update label table, random produce new mark and all keypad character one_to_one corresponding and stores.
Concrete, the table that server stores keypad character is corresponding with mark, and at every turn produce that new mark is corresponding with picture to be associated when using, and upgrade this and show, wherein identifying is server stochastic generation, and just thinks secondary effective.
In step 3, client obtains keypad character to be transmitted according to the sensitive information that user inputs, and equally, with soft keyboard citing on mobile phone A PP, is specially:
Suppose that user needs the sensitive information transmitted to be ABCD tetra-letters, user clicks corresponding character picture by mouse and inputs sensitive information on the soft keyboard of client, client obtains keypad character waiting for transmission, and obtain the mark corresponding to these four keypad characters of current ABCD by server, wherein be designated server stochastic generation, at every turn different.By the mark generating identification information of correspondence, the sensitive information by user converts safe identification information to, improves the security of sensitive information transmitting procedure.
Below for the soft keyboard transmission sensitive information letter ABCD on mobile phone A PP, elaborate the course of work that the safe transmission method of a kind of sensitive information of the present invention Anti-theft is concrete, as follows:
First name placement is carried out to the keypad character on soft keyboard, generate randomly ordered rule by keypad character random alignment by SOTP algorithm.
Keypad character is stored in label table by server, and produces random mark and keypad character one_to_one corresponding and store, and forms keypad character and identifies label table one to one.Fig. 2 is the safe transmission method label table part composition diagram of a kind of sensitive information Anti-theft of the present invention, wherein keypad character ABCD and mark one_to_one corresponding.
Cell-phone customer terminal obtains the mark of symbol picture on the soft keyboard of this time transaction to background server.(conclude the business, the mark on soft keyboard corresponding to symbol picture is all different at every turn, is background server stochastic generation and distributes, therefore before inputting, the mark in background server meeting updating form). next time
User starts to input sensitive information by soft keyboard, is namely clicked the character picture of soft keyboard upper keyboard character ABCD by mouse.
The keypad character ABCD that cell-phone customer terminal inputs according to user, get be ABCD respectively corresponding to mark, can obtain with reference to Fig. 2, mark 1,111 2,222 3,333 4444, mark is packaged into identification information, is namely expressed as identification string 1,111 2,222 3,333 4444.
Identification information 1,111 2,222 3,333 4444, current time information and mobile phone hardware ID are encrypted.Adopt SOTP algorithm to calculate the first ciphertext, and be sent to server.
Server receives the first ciphertext that client sends, and the same inverse operation deciphering adopting SOTP algorithm, obtains identification information 1,111 2,222 3,333 4444, identification information is divided into mark 1111 simultaneously, mark 2222, mark 3333, mark 4444.The label table that server lookup stores, obtains the keypad character corresponding with current identification, and the value explaining user's input is ABCD.
