Problems solved by technology

[0003] Developers follow the minimum principle when writing Android applications, that is, only request permissions related to these operations and resources for which operations or resources are used. However, many development documents themselves are not perfect, or the permission names are relatively close, resulting in Too many permissions that will not be used
The attacker will not only bring misunderstanding to the user, make the user doubt the reliability of the program and the confidentiality of personal privacy, but also be used by other malicious programs due to the existing loopholes, bringing security risks

Abstract

The invention provides a data processing method for a portable device. The method comprises: uncompressing an application installation package file to obtain a byte code file and a Manifest file; extracting all API calls in a program by traversing the byte code file, and analyzing corresponding rights required in APIs; modifying rights required by the Manifest file, and deleting rights which are requested but not used; and re-integrating the Manifest file subjected to right modification and the byte code file into an installation package file. According to the data processing method for the portable device, provided by the invention, the right of the application program is analyzed and constrained, so that the security and reliability of the program are improved and the correct operation of the program is not influenced.

Description

technical field [0001] The invention relates to the mobile Internet, in particular to a data processing method of a portable device. Background technique [0002] With the development of the mobile Internet, the penetration rate of portable terminal equipment continues to increase, and people pay more and more attention to security issues. While more and more applications bring convenience to users, they also store user private data. Due to the open source of the system and the openness of the application market, the Android platform is extremely vulnerable to attacks. If an application wants to perform certain operations or use certain resources through the API provided by the system, it must have the corresponding permission of the API. These permissions must be requested in the program's Manifest file. When the application is installed, the system will check and remind the user which permissions the application specifically requests. [0003] Developers follow the mini...
