Terminal data transmission method and system for Android capacitive screen

Abstract

The invention provides a terminal data transmission method and system for an Android capacitive screen. Connection between Android capacitive screen terminals is established and data transmission affirming interfaces are generated on the Android capacitive screen terminals; affirming or canceling information, which is input by the affirming interfaces, is acquired; after the affirming or canceling information, which is input by the affirming interfaces, is acquired, data transmission is carried out between the Android capacitive screen terminals; before the data transmission, the affirming interfaces are increased, and a user determines whether subsequent data transmission is authorized or not; only if the authorization is confirmed, the data transmission can be carried out, and the data transmission safety and reliability are guaranteed; incorrect data transmission caused by a series of improper and unauthorized incorrect operation is avoided; a phenomenon that a C base is directly called by malicious software by virtue of a JNI technology and data is illegally stolen can be prevented; and furthermore, the affirming interfaces are generated correspondingly before data transmission each time, and the data transmission each time can be authorized respectively and is not uniformly authorized, so that an authority mechanism has flexibility.

Description

technical field [0001] The invention relates to a data transmission method and system for an Android capacitive screen terminal. Background technique [0002] The permission mechanism of Android (android) has some flaws that cannot be ignored, which are manifested in the following aspects: [0003] First, once the permission is granted to the application, the permission will be valid during the life of the application, and the user cannot deprive the permission; [0004] Second, the permission mechanism is inflexible, either all the permissions required by the application are approved, or the installation of the application is rejected; [0005] Third, the permission mechanism is not secure enough to prevent malicious software from directly calling the C library through JNI (Java Native Interface) technology to obtain system services. [0006] Due to the security mechanism of the Android system, there may be security issues such as system infection, information leakage, et...

AI Technical Summary

Problems solved by technology

[0003] First, once the permission is granted to the application, the permission will be valid during the life of the application, and the user cannot deprive the permission;

[0004] Second, the permission mechanism is inflexible, either all the permissions required by the application are approved, or the installation of the application is rejected;

[0005] Third, the permission mechanism is not secure enough to prevent malware from directly calling the C library through JNI (Java Native Interface) technology to obtain system services

[0006] Due to the security mechanism of the Android system, some users may transmit data due to improper or unauthorized operations, which may lead to security issues such as system infection, information leakage, etc.
