Law enforcement agencies must always operate within the boundaries of the law.

When saving online images, it is crucial to capture and preserve the associated metadata. Metadata includes information such as the date and time the image was taken, the device used, and the location. This information can be critical in establishing the authenticity and context of the image during investigations. Tools and techniques should be employed to ensure the integrity of the metadata and prevent any tampering.


Document the Chain of Custody

Maintaining a clear and well-documented chain of custody is essential for preserving the integrity of online image evidence. This includes recording the individuals who handled the evidence, the dates and times of transfers, and any relevant information regarding the storage and preservation of the images. By establishing a solid chain of custody, law enforcement agencies can demonstrate that the evidence has not been tampered with, ensuring its credibility in court.



Use Forensic Image Capture Tools

It is crucial to select reputable and reliable software or hardware solutions and stay updated with the latest technological advancements in the field.




Preserve the Source and Context

In addition to capturing the images themselves, it is equally important to preserve the source and context of the images. This includes saving the webpage URL, social media post, or platform where the image was originally found. By maintaining this information, law enforcement agencies can provide crucial context to support their investigations and establish the authenticity and origin of the image.
