Problems solved by technology

[0003] The implicit authentication method mentioned in the related technology uses the cloud platform for classification processing, but it does not take into account that the cloud platform is a semi-trusted organization. When the mobile terminal sends the user behavior to be classified to the cloud platform, it will cause user privacy leakage

Embodiment Construction

[0046] The present invention will be described below with reference to the accompanying drawings and embodiments.

[0047] The embodiment of the present invention provides an implicit authentication method, and the method is applied to the mobile terminal side, such as figure 1 shown, including:

[0048] Step 101: Encrypt the user behavior data to be classified using the user public key, and send the encrypted user behavior data ciphertext to the big data platform;

[0049] Step 102: Receive the classification result of the user behavior data ciphertext based on the support vector machine SVM algorithm by the big data platform;

[0050] Step 103: Decrypt the classification result based on the user's private key and complete the authentication.

[0051] In the embodiment of the present invention, the mobile terminal encrypts the user behavior data to be classified by using the user public key and sends it to the big data platform, so that the semi-trusted big data platform ca...

Abstract

Embodiments of the present invention provide an implicit authentication method, device, and computer-readable storage medium. The method includes: encrypting user behavior data to be classified by using a user public key, and sending the encrypted user behavior data ciphertext to The big data platform: receiving the classification result of the user behavior data ciphertext based on the support vector machine (SVM) algorithm by the big data platform; decrypting the classification result based on the user private key and completing the authentication.

Description

technical field [0001] The present invention relates to the field of mobile communication technologies, and in particular, to an implicit authentication method, device and computer-readable storage medium. Background technique [0002] With the rapid development of mobile networks and the popularization of mobile terminals, more and more identity authentication is completed on mobile terminals (mobile devices). At present, an identity authentication method commonly used on mobile terminals is explicit authentication. Implicit authentication corresponding to explicit authentication has been proposed in the past two years. Implicit authentication refers to completing identity authentication without the user's perception through the user's unique behavioral habits or biometric data. [0003] The implicit authentication method mentioned in the related art uses the cloud platform for classification processing, but does not consider that the cloud platform is a semi-trusted organ...
