From a secrecy model of information security to a usage authentication model

We continue to be plagued by data breaches, password and credit card dumps, healthcare records...etc. One of the reasons many of these breaches continue to be devastating and effective for cyber criminals is because our current information use infrastructure/architecture relies on secrecy as the primary mode for preventing the misuse of information. Secrecy simply means only the people who have the right to use a bit of information have access to it, when that assumption breaks down as it does with data breaches, the related information can lose some or all its value. For instance a compromised credit/debit card number means getting a new number. A compromised password database means changing the passwords...etc Secrecy has its use as a privacy preserving mechanism but is fairly flawed as an information usage authentication mechanism. The idea of secrecy as the mechanism for controlling the use of information is deeply ingrained, so much so that even people who should know better often

The dubiousness of digitized signature services

Notice I referred to "digitized" instead of digital, this is a very important distinction. These services essentially offer ways to transport handwritten scribbles into digital processes. They can be anything from attaching a Microsoft paint scribble or a scan of one written on a piece of paper, to custom font generation that makes  your signature look like you are a former president of the united states. I wont mention any such services by name but if you've purchased a house or engaged in any sort of contract paperwork activity (leases..etc) you have likely encountered these services. Last I checked, one of these companies is worth north of $40B, no doubt reflecting the size of the market for such services. First, what is the purpose of any signature? as the name suggests, it is primarily to ascribe provenance to something, be it an abstract thing such as a legal agreement expressed in writing or a physical object such as a painting. We also use the notion of signature

Making Internet Information Trust An Inexpensive Commodity

  Certisfy is a service that makes internet information trust a commodity.
