We have a client who is asking how files are validated when draging-and-droping files into Laserfiche. That is how to do you know that a file was not corrupted during the copy/move action. Specifically, the client wants to drag law enforcement body cam footage into Laserfiche in bulk, with assurances that the video files are copied without issue. Are there check-sums created and validated during the import process to ensure file integrity?

TCP already can detect loss and corruption at the packet level, so there's already that protection. Using SSL on your connections would add a further layer of integrity validation, and can protect against malicious attempts to modify the data on the wire. If you need further assurance, it wouldn't be a difficult integration to compare the imported file with the local original, either byte-by-byte or with a cryptographic hash.

One way you could validate the integrity of your video files is to schedule a workflow to run upon import . Your workflow could evaluate the size of the file and if the file size for each video does not match as expected, you can notify an admin that the video is invalid.

Thanks for validating how the Laserfiche import is working. We will likely need to go with building something with the toolkit as you suggested, we just needed to validate this isn't something was already taking place upon import. Thanks again!
