US Patent 10192074 Technique for data loss prevention through clipboard operations

Techniques describe preventing sensitive data from being misappropriated during a clipboard operation. A copy operation for data being copied to a clipboard is intercepted.

A paste operation is evaluated based on the data, and the information is evaluated against a policy to determine whether the paste operation should be blocked.
