What it doesn't know is just how much information the whistleblower took with him when he left. "We have to demonstrate the the hardware has not been tampered with says Ericsson CTO Jason Hoffman. "It keeps honest people honest he says. Rather, it stores what's called a cryptographic hash, a long and unique mathematically-generated string of letters and numbers that corresponds to the original piece of data. Formal verification might sound arcane but if you want to build a house you had better make sure the foundations are solid and formal methods and verification are the basis of everything we. Another challenge is the proliferation of legal definitions that may mean that these jurisdictions are out of step, and complicate legal processes or application of the technology, she said.
