Mobile Software Upgrade Package Encryption and Self-Triggered Unpacking
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing methods for upgrading mobile terminal software are complex for users and lack security, as they require professional knowledge and expose the version files, making them vulnerable to unauthorized access.
Innovation Solution
A method and apparatus for packing a version upgrade software package that encrypts the software, includes a self-triggered unpacking program, and saves files in hidden directories, ensuring only authorized decryption and installation, thereby enhancing security and simplifying user operations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If all required files are merged and decompressed to the install directory for user installation, then the user can install the software themselves, but the operation complexity increases and users without professional knowledge cannot operate it
Solution Approach 1:
The patent implements automatic detection and installation by having the system itself perform the installation process. The detection program automatically identifies the mobile terminal model, queries the server for corresponding software packages, and completes installation without user intervention, transforming a manual process into an automated self-service system.
Solution Approach 2:
The patent prepares software packages for multiple mobile terminal models in advance on the server. When a detection program runs, the matching software package is already prepared and can be immediately installed, eliminating the need for users to manually search, download, and configure installation files.
2Ease of operation
If the version file is directly exposed to users by decompressing to install directory, then the installation process is simple, but the software security is reduced and version files can be easily acquired by users with high professional knowledge
Solution Approach 1:
The patent extracts the critical version file from the installation package and keeps it encrypted on the server. Only the detection program can access and decrypt this file temporarily during the installation process, preventing users from directly accessing or copying the version file while still enabling successful installation.
Solution Approach 2:
The patent introduces a detection program as an intermediary between the user and the version file. This intermediary component handles all interactions with the version file securely, including decryption and installation, while preventing direct user access to the sensitive file.
3Reliability
If professional technicians manually write the new version file to the mobile terminal, then the software security is maintained, but the users cannot learn and use the latest service in time and the after-sale service cost is high
Solution Approach 1:
The patent replaces the manual mechanical process of technicians physically writing files to terminals with an automated electronic detection and installation system. The detection program automatically queries the server, downloads the appropriate software package, and installs it, eliminating the need for manual intervention while maintaining security through encrypted file delivery.
Solution Approach 2:
The patent enables rapid replication and distribution of software packages from the server to multiple mobile terminals. The detection program can quickly copy the appropriate software package from the server to the target device and install it, dramatically reducing the time required compared to manual technician operations.
