OpenStreetMap
HELLO USERS! Greetings!
I just would like to know if Openstreetmap has security measures to detect and correct false data entries.. Example: displacement or replacement of critical buildings. What if somebody accidentally or intentionally relocated some of your buildings? What is our assurance that what is being presented is new and true? Any thoughts on this? Thanks for the comments..

Welcome to OpenStreetMap.
First of all OpenStreetMap is a collaborative mapping platform, data is, and will always be available for editing and modification by anyone with an OSM account, whatever their intentions maybe.
The advantages of keeping the data sets Free and Open currently outweighs the risk of modifications made erroneously and or with the intent to vandalize. Most of the edits are made to fix an error, update the data, or create new ones.
With regards to any assurance about validity and authenticity, only a local community can do that. Data in OpenStreetMap come mainly from tracing satellite imagery (which is quite good for buildings, highways, waterways, and settlements.) adding details require personal or local knowledge, and the best source for that is the local community.
Your office, the local DRRMO, is in a good position to help validate data and actually promote mapping in your own community.
You can monitor changes in your particular geographic area of interest using several tools:
The OSMPH community is on Slack, in case you want to chat or ask further questions from the rest of the active community: https://is.gd/osmphchat

The tools I mentioned for monitoring changsets are non-exhaustive. There are many, other tools out there which you can integrate into your own workflow.

https://wiki.openstreetmap.org/wiki/Osmose helps a lot to find mistakes, intentional or not. Changeset discussions also tend to bring many eyeballs to a particular area.
