Abstract:
1. A method comprising: retrieving a first scrambled version and a second scrambled version of unique identifying data by executing a retrieval process, the first and second versions being produced by reversibly scrambling the unique identifying data in response to a client computing device establishing a connection with a backend computing device, wherein the first scrambled version of the unique identifying data is stored at a first predetermined location of the client computing device and the second scrambled version of the unique identifying data is stored at a second predetermined location of the client computing device, different from the first predetermined location; unscrambling the retrieved first scrambled version to produce a first unscrambled version of the unique identifying data; unscrambling the retrieved second scrambled version to produce a second unscrambled version of the unique identifying data; comparing the first unscrambled version and second unscrambled version; and sending data representative of the comparison to the backend computing device.
