Providing for analysis of artifacts of electronic devices to generate data that is substantially unique to a particular device or to a class of devices is described herein. In some aspects, analyzed artifacts are chosen based on reliable reproducibility of such data over many analyses. The substantially unique data can be associated with a particular electronic device(s) to distinguish such devices from other devices. In some aspects, the generated data is first transformed into an identifier, such as a number, word, string of data, etc., to distinguish the electronic device in remote communication, to provide a key in an encryption/decryption algorithm, and so on. The data can be reproduced by reanalyzing the artifacts, and thus need not be stored for future consumption, mitigating risks involved in storing sensitive data.
