  • Holding law enforcement accountable for electronic surveillance
    on August 8, 2018 at 11:54 am

    A new cryptographic system is aimed at improving government accountability for surveillance while still maintaining enough confidentiality for police to do their jobs. AUDIT involves a public ledger in which officials share information about data requests through so-called 'cryptographic commitments.' If the courts decide to release the data they requested, the public can be assured that the correct documents were released in full; if they decide not to, then that refusal itself is made known. […]

  • Research supports restrictions on opioid-containing cold medicines for children
    on May 22, 2018 at 4:33 pm

  • Tricking the eye to defeat shoulder surfing attacks
    on August 22, 2017 at 7:36 pm

    Researchers have developed the first application to combat 'shoulder-surfing' of PINS and passwords: a hybrid-image keyboard that appears one way to the close-up user and differently at a distance. The technology blends one image of a keyboard configuration with high spatial frequency and a completely different one with low spatial frequency. Experiments showed it was effective for mobile phones and when video cameras recorded PIN entry, as might happen at an ATM. […]
