Embodiment Construction

[0020] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0021] In the embodiment of the present invention, before the application installation package is released to the outside world, the data in the installation package is encrypted, and a dynamic link library for decrypting data is added to the installation package, so that the installation package can be called after running The dynamic link library performs data decryption processing, restores the original data, and completes the installation. This solution avoids the situation that the data in the installation package is directly leaked to non-developers before the installation package runs, effec...

Abstract

A data protection method for an application installation package includes at a computer having one or more processors and memory storing programs executed by the one or more processors, extracting an application installation package into an installation folder; adding a dynamic link library into the installation folder; encrypting an executable file in the installation folder according to an encryption algorithm; adding a procedure of invoking the dynamic link library into the encrypted executable file; and modifying a configuration file in the installation folder such that the dynamic link library is invoked first when the encrypted executable file is executed, wherein the dynamic link library is configured to decrypt the encrypted executable file during installation.

Description

technical field [0001] The invention belongs to the technical field of software, and in particular relates to a data protection method and device for an application program installation package. Background technique [0002] Today, with the rapid development of mobile terminal software and hardware, the development of mobile terminal applications is also changing with each passing day. Every day, a large number of applications are added to the electronic market. By accessing the Internet through mobile terminals, these applications can be realized anytime, anywhere. Download and install. [0003] However, the existing technology lacks effective protection measures for the data in the mobile terminal application installation package. Anyone can obtain the installation package through the electronic market or other sharing channels, extract the files in the installation package, and analyze the key information in the file. data, which makes it easy for competitors of some app...
