Embodiment 1

[0042] A screen-based smartphone digital password unlocking method, the screen pressing smartphone digital password unlocking system mainly includes four modules: Android demo application, intranet penetration, web service and data collection processing and training, The Android Demo application terminal is designed UI interface and collects raw data. The intranet penetration is performed via the FRP service, transfer data to the web service of the PC side, and finally processes the collected data collected and training the model; return to the model Return / Tap the judgment result and reverse transfer back to the Android side; the implementation function mainly includes two aspects, the first aspect is to set the password phase, which can be used according to the user's screen pressing habitual intelligence to determine the user's single pressing is heavy press. Still tapping; the second aspect is to use the password unlock phase, which can be based on the current set of pressin...

Embodiment approach

[0061] Step S0101: Design and implement Image 6 with Figure 7 The setting password and unlocking interface shown are set, the core part of the interface is a custom component, including 4-bit empty circles that display password input state (input numbers become solid round), "0" to "9" 10 Number buttons and "Delete" button. The overall layout of the interface is RelativeLayout, including the above custom component and the "confirm" / "return" button below.

[0062] Step S0102: Implementing interactive logic and feedback within two interfaces. For setting password interface, press each digital button, store the digital value corresponding to the button, and request the remote API, the request parameter is the time long, press the contact area, and the contact area is lifted, the average contact area, Press the pressure value, lift the pressure value and the average pressure value, the return value is 1 (re-press) or 0 (tap), and store the return value of the re-press and tap inform...

Abstract

The invention discloses a smart phone digital password unlocking method based on screen pressing force, and belongs to the field of keystroke dynamics and user identification authentication. The method comprises the steps that a UI interface is designed at an Android end, original data are collected, intranet penetration is completed through frp service, the data are transmitted to Web service of a PC end, and finally the PC end processes the collected data and trains a model; and according to the trained model, a re-pressing / light-pressing judgment result is fed back, and is inversely transmitted to the Android end.

Description

Technical field [0001] The present invention relates to the field of hit kinetic and user identification certification, and more particularly to a smartphone digital password unlocking method based on the screen. Background technique [0002] The current user identification certification technology is divided into two categories: a class is a traditional password unlocking technology, including a PIN-based password (digital password) unlocking technology (generally 4-bit PIN and 6-bit PIN) and Based on the nine-square graphics Password unlocking technology; another type is biometric unlocking technique, including fingerprint recognition unlocking techniques, including physical buttons fingerprint recognition, back fingerprint recognition, and screen fingerprint recognition) and facial identification unlocking techniques. [0003] Because of the limitations of current sensor hardware technology, fingerprint recognition unlocking and facial recognition unlocking biological identifi...
