Abstract

The utility model relates to a voiceprint verification system of a mobile phone. The voiceprint verification system is characterized by comprising a voiceprint acquisition module, a voiceprint registration module, a voiceprint verification module and a voiceprint verification server, wherein the voiceprint acquisition module comprises a microphone transmitter and a voice processing circuit; the voiceprint registration module comprises a voiceprint filter processor and a wireless data sender; the voiceprint filter processor can filter a digital voice signal which is acquired and processed by the voiceprint acquisition module so as to acquire a usable voiceprint characteristic signal to be sent to the voiceprint verification server through the wireless data sender; the voiceprint verification module comprises a preset threshold value comparison processor and can calculate the similarity percentage of voiceprint characteristics of a verifier and a registrant; and the voiceprint verification server is established in a cloud and can store and file voiceprint characteristics and rights of different users. Due to the uniqueness of individual voice, a user is verified by the voiceprint verification server, thus the safety is guaranteed, the possibility that the voiceprint verification system is cracked is reduced, and the effect of using convenience is achieved.

Description

A kind of mobile phone vocal print verification system

Technical field

The utility model relates to information security field, particularly a kind of technology of utilizing the vocal print checking as mobile phone mobile application security password.

Background technology

Along with the growth of popularizing, moving bandwidth of smart mobile phone, mobile phone becomes mobile application terminal gradually.And mobile phone is as a kind of private personal effects, and the involved individual privacy safety problem of various application software also more and more receives users' concern in its system.As: individual's log, mobile payment number of the account, Mobile business consumption record etc. all are privacies that the user needs protection.

To these user privacy informations that needs protection, the major technique means that adopt in the market are numerical ciphers encryption technologies, and there is following shortcoming in this technology: receive the restriction of mobile phone key, generally only can use numerical ciphers, the intensity of password is not high; Password needs the user to remember, and too weak point is too regular breaks through easily, and oversize being not easy to again remembered; Different application software adopts different passwords, can improve fail safe, but more is not easy to memory; There is a broken complete broken risk in the password that the soft employing of different application is identical.

The utility model content

To existing technical problem in the above prior art of mentioning; The purpose of the utility model is: a kind of mobile phone vocal print verification system is provided; Utilize the human body vocal print as authentication password, solve existing numerical ciphers as the existing technical problem of mobile phone security protection.

The utility model solves the technical scheme that its technical problem adopted: a kind of mobile phone vocal print verification system is provided, and its characteristic comprises, and vocal print acquisition module, vocal print Registering modules, vocal print authentication module and vocal print authentication server constitute;

Said vocal print acquisition module is made up of transmitter and speech processing circuit, can convert analog voice signal into audio digital signals; Said vocal print Registering modules is made up of vocal print filter processor and wireless data transmitter; Said vocal print filter processor can obtain available vocal print characteristic signal through filtering with the audio digital signals that said vocal print acquisition module acquisition process goes out, and send to said vocal print authentication server through said wireless data transmitter; Said vocal print authentication module comprises pre-set threshold value comparison processor, can calculate the similar percentage of verifier and registrant's vocal print characteristic; Said vocal print authentication server is based upon high in the clouds, can store and file the vocal print characteristic and the authority of different user.

The beneficial effect of the utility model is fail safe: utilize the uniqueness of personal voice biological characteristic, through the checking of comparing of vocal print authentication server, ensured fail safe, further reduced the possibility that is cracked simultaneously; Convenience: saved numerous and diverse manual keyboard input through the Application on Voiceprint Recognition technology, the user need not to various application software memory ciphers; Personalized: inherently safe requires can be self-defined by the cellphone subscriber; Hardware requirement is low: general mobile phone can be realized; Support languages: any languages; Confidentiality: have not transferability, promptly other people obtain mobile phone and release success, but do not have owner's voice messaging still can't use application software wherein, can't obtain wherein data and use, so safer.

Description of drawings

Fig. 1 is the system configuration sketch map of the utility model; Fig. 2 is the system implementation flow chart of the utility model.

Embodiment

Below in conjunction with accompanying drawing, the utility model is further specified, as shown in Figure 1, a kind of mobile phone vocal print verification system, its characteristic comprises, and vocal print acquisition module, vocal print Registering modules, vocal print authentication module and vocal print authentication server constitute; Said vocal print acquisition module is made up of transmitter and speech processing circuit, can convert analog voice signal into audio digital signals; Said vocal print Registering modules is made up of vocal print filter processor and wireless data transmitter; Said vocal print filter processor can obtain available vocal print characteristic signal through filtering with the audio digital signals that said vocal print acquisition module acquisition process goes out, and send to said vocal print authentication server through said wireless data transmitter; Said vocal print authentication module comprises pre-set threshold value comparison processor, can calculate the similar percentage of verifier and registrant's vocal print characteristic; Said vocal print authentication server is based upon high in the clouds, can store and file the vocal print characteristic and the authority of different user.

Embodiment is as shown in Figure 2: use first and need carry out the vocal print registration, mobile phone can be uploaded herd number and vocal print characteristic to the vocal print authentication server through the vocal print Registering modules, and on server, sets up registrant's vocal print characteristic archives; Different according to the vocal print Validation Mode, ask the user with saying a checking statement; Wireless data transmitter is sent an information to high in the clouds vocal print authentication server simultaneously, and the vocal print authentication server can be with the wireless vocal print authentication module that sends to of registrant's voiceprint; The vocal print authentication module is compared verifier's vocal print characteristic and registrant's vocal print characteristic again, returns similar percentage; If this probability surpasses the threshold values of setting, then allow the user to use this software, otherwise refuse and charge to security log.
