specific example

[0040] The unlocking interface contains n1 key icons and n2 lock icons, and the total number of unlocking icons is n=n1+n2, where the position of each unlocking icon is determined by a randomization algorithm;

[0041] First, construct a hash table with a total of n elements, each of which corresponds to an unlock icon (lock or key), and each element has two attributes: one is the index path of the unlock icon; the other is for marking The character string of the unlocking icon pairing relationship. The key preset by the user is marked as "true key", the corresponding correct lock is marked as "true lock", and other unlocking icons are marked as "false". These marks will be used to judge unlocking pairing correctness. Then, use the automatic shuffle function to randomize the position subscripts of these n elements. Finally, when generating the unlock interface, the program will take out all the unlock icons in the order after randomization, and display the unlock icons in the...

Abstract

The invention discloses a random screen unlocking system of mobile terminal equipment. The random screen unlocking system comprises a configuration module, a screen monitoring module, a screen locking module, a touch event handling module and a touch release event handling module. A random screen unlocking method based on the random screen unlocking system comprises the following steps of: when a screen is turned off, computing a position set of each key and each lock, namely a starting point and an ending point of an unlocking path, by using a randomization algorithm, and generating a screen locking interface according to the set; when the screen is turned on, displaying an unlocking icon, and monitoring the touch of a user; when the user touches the key on the screen, namely the starting point of the unlocking path, generating a dynamic icon which moves along with a movement track of a finger of the user; when the user releases the key on the lock, judging whether the user puts the correct key on the correct lock; and if so, successfully unlocking the screen. By the invention, the paths of unlocking operation at each time are different, screen loss caused by long-term sliding is reduced, the probability of misoperation is reduced, the quantity of matched combinations is increased, and the safety of screen locking is ensured.

Description

technical field [0001] The invention relates to a mobile device supporting a mobile operating system, in particular to a random screen unlocking system and method for a mobile terminal device. Background technique [0002] With the development of Internet and communication technology, mobile devices have attracted more and more users' attention due to their excellent portability and operability. And especially with the invention of the Android system, it stimulates the wave of popularization of large-screen touch devices. In order to prolong the life of the screen and save battery energy, the mobile device will turn off the screen and enter the lock screen state when it is not operated for a long time. The user needs to perform a specific unlocking operation to close the lock screen interface and enter the main interface. [0003] At present, there are many screen unlocking schemes, such as patent CN102520857, which realizes unlocking by detecting whether the sliding track...
