In an approach, a processor receives device identification information corresponding to at least one device local to a location of a transaction. A processor receives notification of an infected user. A processor determines that the infected user is associated with the transaction. A processor identifies a second user from the device identification information. A processor sends a notification to the second user.

Contact tracing utilizing device signatures captured during transactions

Embodiments are disclosed for a method. The method includes generating a correction datastore indicating shifts in magnitude representing corresponding characters that uniquely identify hardware comprising a computer processing chip. The method further includes generating security masks based on a correction file. Additionally, the method includes using a correction process for the computer processing chip. The generated security masks include corresponding overlays representing the shifts in magnitude with respect to corresponding product masks for the computer processing chip. The method also includes generating the computer processing chip using the security masks and the product masks.
