Problems solved by technology

[0008] If a system uses 8-digit numbers as a password, there will be 100,000,000 password possibilities during verification. It can be seen that the voiceprint system faces two challenges; first, due to the large number of passwords, the training model is not well differentiated; Second, the recognition rate of digital recognition is low

Embodiment 1

[0034] Such as Figure 1-2 As shown, the implementation method of the dynamic voiceprint encryption system described in the embodiment of the present invention mainly includes the following steps:

[0035] First of all, in the voiceprint encryption system, a set of fixed number strings is added to be used in the process of voiceprint registration and verification. This set includes a limited number of fixed number string combinations or fixed character string combinations set in advance, for example, it may include 300 8-digit strings, 10 10-digit strings, 200 9-digit strings;

[0036] (2) Then, during the registration process, the system randomly selects a combination from these fixed number string combinations or fixed character string combinations as a password and displays it to the user;

[0037] (3) The user reads the password according to the prompt, and the voiceprint system generates the user's voiceprint information;

[0038] (4) Then, during the verification proce...

Embodiment 2

[0042] Such as Figure 1-2 As shown, the implementation method of the dynamic voiceprint encryption system described in the embodiment of the present invention mainly includes the following steps:

[0043] (1) First, add a fixed number string set to the voiceprint encryption system for the process of voiceprint registration and verification. This set includes a number of preset limited number of fixed string combinations, for example, including 100 4-digit String, 1 10-digit string, 200 6-digit strings;

[0044] (2) Then, during the registration process, the system randomly selects a combination from these fixed string combinations as a password and displays it to the user;

[0045] (3) The user reads the password according to the prompt, and the voiceprint system generates the user's voiceprint information;

[0046] (4) Then, during the verification process, the voiceprint system randomly selects a fixed string combination from the limited password, and the user reads it ac...

Abstract

The invention relates to a method for realizing dynamic voiceprint password system, and the method comprises the following steps: adding fixed numeric strings or string sets into the voiceprint password system so that the system can randomly pick from the combinations of these fixed numeric strings and the string sets one combination as passwords; accessing the passwords by a user according to prompting information; generating voiceprint information for the user by the voiceprint system; in the verification process, randomly selecting the combination from limited passwords by the voiceprint system so that the user can access based on the prompting information; comparing the voiceprint characteristics by the voiceprint system; identifying the combination the user accesses; and outputting the confidence by the voiceprint system. According to the invention, the number of passwords is greatly reduced. The voiceprint system can more easily train the separation from different people. Since the identification contents are reduced, the identification rate is increased. As a result, the problem with counterfeit of passwords for relevant system can be resolved and the space for voiceprint can be reduced.

Description

technical field [0001] The invention relates to voiceprint security identification technology, in particular to a method for realizing a dynamic voiceprint encryption system. Background technique [0002] In real life, each person's voice has its own characteristics when speaking. People who are very familiar with each other can be distinguished from each other only by listening to the voice. This is the characteristic of different speakers. [0003] Vocal resonators include the pharynx, oral cavity, and nasal cavity. Small differences in these organs will lead to changes in the airflow of the vocalization, resulting in differences in sound quality and timbre; The difference between sound intensity and sound length; pitch, sound intensity, sound length, and timbre are called the "four elements" of speech in linguistics, and these factors can be decomposed into more than 90 characteristics. Different wavelengths, frequencies, strengths, and rhythms, the voiceprinter can conv...
