As shown in Figure 1, it is the application schematic diagram of the cipher protection system 100 of a better embodiment.This cipher protection system 100 comprises client 20 and service end 40.Client 20 is connected with service end 40 by network 10.Client 20 can be PC, smart mobile phone etc.The internetwork connection mode that client 20 and service end 40 are set up can be wireless mode or wired mode.
Biomedical information acquisition device 21 is used to gather user biological information, and biological information is offered password generation device 22.Wherein, this biological information can be user's finger print information, iris information etc.
Please be simultaneously referring to Fig. 2, it is the functional block diagram of password generation device 22 among Fig. 1.Password generation device 22 comprises biological information description unit 222, chooses unit 223, converting unit 224 and grouped element 225.
The user biological information that biological information description unit 222 is used for collecting is converted to one group of binary code.
Choose unit 223 and be used to respond transfer operation, from this group binary code, select the fixedly binary code of figure place according to pre-defined rule.
Converting unit 224 is used for choosing the binary code of selecting unit 223 according to this and produces corresponding digital value.
Grouped element 225 is used for will being divided into a plurality of son groups by this group binary code of these biological information description unit 222 conversions according to the digital value that produces, and should be distributed to the password authentification end as subcipher by a plurality of son group binary codes.
Please be simultaneously referring to Fig. 3, it is the functional block diagram of service end 40 among Fig. 1.Service end 40 comprises communication module 41, memory module 42 and password authentication module 43.
For ease of understanding, below be that example is illustrated with the user by access to netwoks bank: client 20 is user's a PC, service end 40 is the server of bank, after PC is gathered user's finger print information, finger print information is converted to one group of binary code of 240, when the user carries out submit operation, PC is obtained last three code of this group binary code, for example this last three code is 110, PC is transformed into the decimal system to obtain digital value 6 with this last three code 110, PC should be organized binary code according to digital value 6 and be divided into six son groups, and PC is distributed to these six son group binary codes the server of bank as subcipher; Stored set when the user registers a benchmark encrypted message group in the server of bank, six passwords have been comprised in this benchmark encrypted message group, the server of bank is when judging all corresponding with six passwords in the benchmark encrypted message group coupling of six son group binary codes, for the user provides service.
As shown in Figure 4, it is the flow chart of the cipher code protection method of a better embodiment.This cipher code protection method is applied to cipher protection system.This cipher protection system comprises client and sets up the service end that network is connected with client.Wherein, client can be PC, smart mobile phone etc.; The internetwork connection mode that client and service end are set up can be wireless mode or wired mode.This method comprises the steps:
Step S300 gathers user biological information, and generates the one group of binary code that is used to describe this biological information.Wherein, this biological information can be user's finger print information, iris information etc.
Step S302, the response transfer operation is selected the fixedly binary code of figure place according to pre-defined rule from this group binary code.
Step S304 produces corresponding digital value according to the binary code of selecting.
Step S306 should organize binary code according to predetermined digital value and be divided into a plurality of son groups.
Step S308 should be distributed to service end as password by a plurality of son group binary codes.
Step S310, service end receives a plurality of son group binary codes of client distribution.
Step S312 carries out matching operation with child group binary code that receives and the benchmark encrypted message group that prestores.For example, choose every group of son group binary code one by one, and search corresponding password from the benchmark encrypted message group that prestores according to the child group binary code of choosing.
Step S314 is when the password in all the son group binary codes determining to receive and benchmark encrypted message group is complementary, for client provides corresponding service.
By above-mentioned cipher protection system 100 and method and password generation device 22; after client 20 is gathered user biological information; biological information is converted to one group of binary code; in client 20 when service end 40 is submitted information to; client 20 should be organized binary code and be divided into a plurality of son groups; and should be distributed to service end 40 as a plurality of subciphers by a plurality of son group binary codes, service end 40 is carried out matching operation by the password in a plurality of subciphers that will receive and the benchmark encrypted message group that prestores and is finished password verification operation.Dynamically produce when service end 40 is submitted information to because password is a client 20, the disabled user can only steal the biological information that collects, and it can not steal the password of dynamic generation, thereby makes user's information be effectively protected.
