Abstract
Methods, systems, articles of manufacture and apparatus are disclosed to reduce spoofing vulnerabilities. An example apparatus to verify token integrity for a computing device includes an artifact engine to store first artifact data with a first timestamp in a device artifact storage, and store second artifact data with a second timestamp in the device artifact storage. The example apparatus includes an offchain identification protector (OIP) controller to generate a first token based on the first artifact data and the first timestamp, the first token to establish a first entry in a blockchain at a first time, and generate a second token based on the second artifact data, the second timestamp, and the first token, the second token to establish a second entry in the blockchain at a second time after the first time. The example apparatus also includes a verify engine to select the first or the second artifact from the device artifact storage, and search for a match of the selected first or second artifact in the blockchain to verify an integrity of the second token at a third time.
