Automated Checksum Validation for Virtual Media Redirection
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current virtual media redirection testing lacks a validating tool to ensure data integrity during the media redirection process, requiring manual verification of redirected files or images against originals.
Innovation Solution
A system and method that utilize a computing device with a processor and storage to perform virtual media redirection testing by calculating checksum values before and after the redirection process, using a validation module to automate the validation by matching these values, and generating a report on the test result.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If manual verification is used to check redirected files against originals, then data integrity can be confirmed, but testing efficiency and productivity are reduced
Solution Approach 1:
The patent replaces manual verification (mechanical human operation) with automated checksum calculation and comparison. The system automatically computes checksum values for original and redirected files, compares them programmatically, and determines data integrity without human intervention, thus maintaining reliability while dramatically improving productivity
Solution Approach 2:
The validation system performs self-verification by automatically calculating checksums, comparing file integrity, and generating validation reports without requiring manual inspection. The system serves itself by implementing the complete validation workflow autonomously, eliminating the need for human testers to manually verify each redirected file
2Device complexity
If no validating tool is available, then the testing process remains simple, but data loss cannot be detected in redirected files
Solution Approach 1:
The system performs preliminary checksum calculation on original files before redirection occurs. This pre-computed checksum serves as a reference value that can be automatically compared against the redirected file's checksum, enabling automatic detection of data loss or corruption without adding complex manual verification steps
Solution Approach 2:
The patent introduces checksum values as an intermediary mechanism to verify file integrity. Instead of directly comparing entire redirected files (which would be complex and time-consuming), the system uses checksum hashes as intermediaries to represent file contents, enabling simple yet reliable integrity verification through numerical comparison
3Measurement precision
If manual checking of redirected file contents is performed, then validation accuracy is achieved, but time consumption increases significantly
Solution Approach 1:
The patent transforms the validation approach by changing from direct file content comparison to checksum value comparison. This parameter transformation converts a complex, time-consuming operation (comparing entire files) into a simple, rapid operation (comparing numerical hash values), thereby maintaining validation accuracy while dramatically reducing verification time
Data Source
AI summary
A system and method to automate validating media redirection in a virtual media redirection testing process. A computing device is provided for performing the test. During the test, the computing device executes an automated script to obtain, from a media storage device, a media file to be redirected, and then calculate a first checksum value for the media file being obtained. The computing device then executes a redirection module to perform the virtual media redirection process for the media file, and copy the media file to a local path of the computing device. Once the media file is redirected, the automated script calculates a second checksum value for the media file at the local path of the computing device. Thus, the media file may be validated by matching the two checksum values, and the redirection process is determined to be successful when the checksum values match.
