The following invention is directed towards user identity verification and utilizes enhanced abilities to detect both a user's identity and confirming that the user is in fact a person and not a bot. The device utilizes Universal Unique Identifiers (UUIDs) indicating the device's interaction with the various environmental and electronic devices located around it. These interactions can indicate if a user has human characteristics. As a user interacts with their device and that device interacts with the surrounding world, a UUID is created and is then stored upon a user's device as well as created in an online database. When a user wishes to access an online service, for example, social media, the user will make a request to that service. The online service may then ask for a list of UUIDs from the user device to verify that they are who they say they are. If these UUIDs satisfy the request, the user identity is confirmed.
