Embodiment 1

[0090] Such as figure 2 As shown, a method for dynamically matching a mobile number and an owner's voiceprint disclosed in an embodiment of the present invention includes the following steps:

[0091] Step S101: Determine whether the voiceprint of the mobile number is the same as the voiceprint of the owner of the mobile number for each call or selected calls within the observation time window, and record the comparison result.

[0092] Step S102: Make statistics on the comparison results, determine whether the voiceprint of the user of the mobile number is the voiceprint of the owner within the first set time range, and obtain the voiceprint of the mobile number user and the owner of the marked mobile number in units of the first time range. Whether the voiceprints are the same continuous string.

[0093] Step S103: Group the obtained continuous character strings according to the set second time range and time interval, and then recombine to obtain the mobile number voicepr...

Embodiment 2

[0103] The above steps of Embodiment 1 have established the dynamic corresponding relationship between the mobile number and the owner's voiceprint based on the time axis. For the convenience of application, it is also necessary to establish the dynamic corresponding relationship between the owner's voiceprint and the mobile number based on the time axis. That is to establish a set of mobile numbers based on the time axis corresponding to the voiceprint of each mobile number owner.

[0104] Based on the dynamic corresponding relationship between the mobile number and the owner's voiceprint based on the time axis, the owner can use several mobile numbers at the same time. By comparing the voiceprints of the owners corresponding to each mobile number, it can be determined that the same The set of mobile numbers corresponding to the voiceprint.

[0105] Create a set of mobile numbers corresponding to the voiceprint of each mobile number owner based on the time axis, which is to m...

Embodiment 3

[0128] On the basis of Embodiment 2, usually the owner voiceprint database of all mobile numbers is relatively large. In order to improve the efficiency of voiceprint matching, this embodiment first conducts initial screening. That is, firstly, from the call peer associated with the target mobile number in the call list, obtain the first-degree call peer mobile number set F of the target mobile number, associate the call peer of the mobile phone in the F set, and obtain the second-degree call peer mobile number of the target mobile number For the number set S, the voiceprint corresponding to the set S is used as the voiceprint set W to be matched for the target mobile number.

Abstract

The invention discloses a method, device and equipment for dynamic matching of a mobile number and a voiceprint and index construction, in particular to the dynamic matching of a mobile number and an owner's voiceprint, the dynamic matching of a mobile number owner's voiceprint and a mobile number, and the dynamic matching of a mobile number and voiceprint. Index construction between fingerprints and ID documents. The invention distinguishes the number user and the number owner, can truly reflect the natural person corresponding to each stage of the mobile number in its life cycle, and substantially improves the confirmation accuracy, convenience and confirmation efficiency of the mobile number owner; The present invention improves the accuracy and efficiency of matching the same voiceprint in a large voiceprint set by fully combining efficient Hamming distance calculation, communication fingerprint pre-computation, and multiple similar calculation logic combinations in a large voiceprint set. This makes it possible for different digital applications to be associated with the same natural person even if they are associated with different mobile numbers.

Description

technical field [0001] The invention relates to the fields of communication and information technology, and in particular to a method, device and equipment for dynamic matching of mobile numbers and voiceprints and index construction. Background technique [0002] With the advent of the era of 5G, Internet of Things, and blockchain applications, the Internet is gradually transitioning from an information network to a value network. With the advent of artificial intelligence and knowledge network applications, data fusion between real space, digital space, and digital space requires a new level. The application of artificial intelligence, knowledge network, and value network requires the key data supporting these network applications to be unique to humans and universal to applications. [0003] There is a need for a method and tool that can easily integrate human behavior in real space and digital space. The fused data must have uniqueness and universality. Applied in all ...
