Researchers have recommended the Australian government abandon its existing digital identity system and start again from scratch, highlighting again security flaws in two of the systems already accredited. Professor Vanessa Teague and Ben Frengley last year disclosed to the Australian Taxation Office (ATO) a weakness in its myGovID system. They found myGovID is subject to an easily implemented code proxying attack, which allows a malicious website to proxy a person's myGovID login and re-use their authentication to log in to the victim's account on any website of their choice. The pair said the ATO, in response, informed them of having no intentions to fix the flaw. The Digital Transformation Agency (DTA) is responsible for the Trusted Digital Identity Framework (TDIF), which is a high-level design for a federated authentication system.

If you are perplexed, befuddled and bewildered about reports of unidentified aerial phenomena (UAP) and possible visitations of alien spacecraft, you can take action with do-it-yourself sky-monitoring gear. Given the low cost and high capability of today's consumer-grade technology, you too can be at the ready to document out-of-the-ordinary events. Enter the world of Sky Hub, a global network of smart sensors designed to snag digital signatures of anomalous events. This crowd-sourced network of smart trackers with "edge processing" uploads data of unusual phenomena to a Sky Hub Cloud. The driving forces empowering the Sky Hub initiative center on the rapid growth and evolution of machine learning for streamlining the analysis of large datasets and the increasing affordability of artificial intelligence (AI)-ready hardware. These advancements can be harnessed to probe the ongoing, baffling behavior of UAP and unidentified flying objects (UFOs) reportedly crisscrossing … [Read more...] about Spotting UFOs: Do-it-yourself sky surveillance comes online
