技术领域technical field
本发明涉及的是一种信息安全领域的技术，具体是一种文本相关声纹密码验证方法。The invention relates to a technology in the field of information security, in particular to a text-related voiceprint password verification method.
背景技术Background technique
声纹识别(Voiceprint Recognition)也称为说话人识别，分为说话人辨认和说话人确认。前者用以判断某段语音是若干人中的哪一个说的；而后者则是判断某段语音是否是特定人所说。任务不同，所采用的技术也不同。Voiceprint Recognition (Voiceprint Recognition), also known as speaker recognition, is divided into speaker identification and speaker confirmation. The former is used to judge which one of several people said a certain speech; while the latter is to judge whether a certain speech is spoken by a specific person. Different tasks require different techniques.
声纹密码验证是说话人确认的一种应用,该方法要求用户输入语音，并据此确认说话人身份。在该应用中用户注册及身份验证通常采用固定密码文本的语音输入(文本相关)，消除了语音内容差异，因而其声纹往往更为一致，相应的可取得相比于文本无关的说话人确认更好的验证效果。目前常用声纹密码往往采用固定数字串(经典模式)或者随机数字串，相对于前者而言，后者最大的特点是能够很好的防止录音回放等攻击，极少数会采用文本无关。Voiceprint password verification is an application of speaker confirmation, which requires the user to input voice and confirm the identity of the speaker accordingly. In this application, user registration and identity verification usually use voice input of fixed password text (text-dependent), which eliminates the difference in voice content, so the voiceprint is often more consistent, and correspondingly can obtain speaker confirmation compared to text-independent Better verification effect. At present, commonly used voiceprint passwords often use fixed number strings (classic mode) or random number strings. Compared with the former, the biggest feature of the latter is that it can well prevent attacks such as recording playback, and very few use text-independent.
现有的声纹密码验证技术的缺点包括：文本无关方式注册、验证的语音数据多，验证过程慢，不适用于实时、用户声纹密码验证，用户体验也较差；文本相关的经典模式存在被窃听的安全风险，更可能受到录音回放的攻击；随机密码提示模式作为文本相关经典模式的一种变型，不存在内容保密性，且相对于文本相关经典模式准确率下降。由于上述的几种方案的各自缺点，声纹识别现阶段并没有得到大规模应用。The disadvantages of the existing voiceprint password verification technology include: text-independent registration and verification require a lot of voice data, the verification process is slow, it is not suitable for real-time, user voiceprint password verification, and the user experience is poor; text-related classic modes exist The security risk of being eavesdropped is more likely to be attacked by recording playback; as a variant of the text-related classic mode, the random password prompt mode has no content confidentiality, and its accuracy rate is lower than that of the text-related classic mode. Due to the respective shortcomings of the above-mentioned several solutions, voiceprint recognition has not been widely used at this stage.
