Letter to the editor: "Edwards curve digital signature algorithm for video integrity verification on blockchain...

Area of Science:

• Forensic Science
• Digital Forensics
• Information Security

Background:

• Ensuring video integrity is critical for legal proceedings, especially with advanced digital alteration tools.
• Existing methods for video verification may lack efficiency or comprehensive security.
• The need for a robust and accessible solution to validate video evidence is paramount.

Discussion:

• The proposed method utilizes BLAKE2b hashing, blockchain technology, and the Edwards Curve Digital Signature Algorithm for robust video data verification.
• Video segments are secured through chronologically chained blocks, with each block containing the prior block's signature for enhanced security.
• This approach ensures tamper-evident recording and validation of video evidence.

Key Insights:

• The technique offers a faster and more secure method for detecting video tampering compared to current state-of-the-art solutions.
• It effectively identifies all forms of video counterfeiting across any file, user, or time.
• The system requires minimal additional storage, making it a practical solution for forensic applications.

Outlook:

• Further research could explore integration with real-time video streaming for immediate integrity verification.
• The method's applicability can be expanded to other forms of digital evidence beyond video.
• Continued security analysis against emerging cyber threats will be essential for long-term reliability.
