Abstract:
The study titled “Design and Implementation of an Evidence Protection System using Blockchain Technology” concludes with remarkable success in attaining its objectives of crafting a resilient and pioneering solution to fortify crucial evidence within various domains. Leveraging the prowess of blockchain technology, the resultant system guarantees an impregnable shield against breaches, instilling security, transparency, and an unyielding defense against any attempts at manipulation.
This research not only addresses the exigent necessity of upholding the sanctity of pivotal evidence but also introduces a revolutionary paradigm that has the potential to revolutionize the very essence of evidence protection across diverse sectors. Through this meticulous study, the horizons for augmenting trust, dependability, and responsibility in the realm of evidence management have been propelled to new frontiers.

Introduction:
Evidence gathering is at the core of every analysis process. The ability to verify the results and have appropriate paperwork, especially if a case lasts for several years, is vital. In later periods, information gathered at the outset of prosecution may become crucial. If the documentation is handled by a system, the judicial authority can find the important facts at the appropriate time quickly (Jamulkar et al., 2022). Blockchain technology is already being used for supply chain tracking to track shipments of goods worldwide, proving that it is an excellent resource and that it would be easy to transfer the same process to the supply chain of evidence.
Theoretically speaking, when blockchain is used in a court setting, a list of the evidence hashes from each case will be available to the prosecution, defense, and judicial authority, along with the physical evidence proposed for use in each case (Billard and David, 2020). The evidence will support the case and the blockchain will add integrity by further enhancing the validity of the evidence. This will allow all parties an easier time determining the validity and facts of said case. As a result, it may increase the speed with which the judge can determine the outcome of the case, and it may decrease the chances of having irrelevant or damaged evidence admitted into the courtroom (Billard and David, 2020).
Also, frivolous cases will be dismissed early and an increased amount of evidence will be proven relevant and validated, making less viable evidence obvious. It may even be possible to have the defense and the prosecution stipulate the validity of the evidence ahead of time, reducing the need for some trials, thereby reducing overall court costs and backlogs.
Moreover, this will ensure there will be a faster, more consistent, and secure justice system because blockchain does not allow for as much human error. In a court setting, an individual accused of a crime would be able to compare a current hash against the evidence collected at the scene to verify the integrity of the evidence and ensure nothing has changed (Billard and David, 2020).
If the judge rules the evidence to be inadmissible, the evidence can be disallowed from court without altering the blockchain. There will be no need to amend the blockchain or change the hash. Because no human-readable information is included in a hash, no one would be able to glean private or unintentionally released information from the list of hashes that are used to check the integrity of the evidence, allowing the hashes on the blockchain to be visible to the public if desired and configured for public view.
This involves training evidence collectors to only label the hashed files with generic terms, such as “Recorded Statement of Witness 1”, “Video from Victim 2’s home”, and “Photograph of Vehicle 2” (Billard and David, 2020).
Without the use of blockchain, the justice system is more vulnerable to human error and intentional tampering, without the ability to track and record evidence sufficiently to prevent false convictions. In a way, using blockchain will allow the justice system to add proof of the validity of the evidence, allowing the evidence to “speak for itself”.
Blockchain is better suited to effectively track and monitor the condition and preservation of evidence by having the security of the blockchain without having the element of human error or criminal intent. Hence, our proposed system will be able to receive evidences and accurately verify the evidences before uploading them.
