The US intelligence community’s broadest surveillance authorities are enshrined in Executive Order 12333, which primarily covers the interception of electronic communications overseas. The Order authorizes the collection, retention, and dissemination of “foreign intelligence” information, which includes information “relating to the capabilities, intentions or activities of foreign powers, organizations or persons.” In other words, so long as they are operating outside the US, intelligence agencies are authorized to collect information about any foreign person — and, of course, any Americans with whom they communicate. The NSA has conceded that EO 12333 is the basis of most of its surveillance. While public information about these programs is limited, a few highlights give a sense of the breadth of EO 12333 operations:
The NSA gathers information about every cell phone call made to, from, and within the Bahamas, Mexico, Kenya, the Philippines, and Afghanistan, and possibly other countries.
A joint US-UK program tapped into the cables connecting internal Yahoo and Google networks to gather e-mail address books and contact lists from their customers.
Another US-UK collaboration collected images from video chats among Yahoo users and possibly other webcam services.
The NSA collects both the content and metadata of hundreds of millions of text messages from around the world.
By tapping into the cables that connect global networks, the NSA has created a database of the location of hundreds of millions of mobile phones outside the US.
Gary Edwards on 09 Sep 10A while back I included the following as one of the areas of interest of the PDF/D Consortium: Structured Documents and Single Sourcing: improving round-trips to document softwareWhat did I mean by Structured Documents? For years Solid Documents has been converting PDF files to Word documents with a focus on retaining format and layout to allow customers to repurpose the content. While this is a great solution for a large amount of customers, it is not the only type of reconstruction that is interesting. PDF is by nature a "document" format: the layout is in the form of pages. Content also needs to exist in alternate formats like a continuously flowing stream. Use cases for continuously flowing content include:conversion to HTML to reflow for form factors other than "pages"conversion to content management systems where structure is more important than layout and formattingconversion for alternate readers for people with disabilities (text to speech, etc)Reconstruction for these use cases focuses more on the structure of the document than on the layout and formatting. For example, we need to take unstructured PDF files and recognize columns, tables, lists, headers and footers, etc. This allows us to organize the content in a logical structure. Ultimately, we'll recognize topics and sections too so that we can produce logical hierarchies from plain old non-tagged PDF files. One great example of where conventional PDF pages are not the most appropriate way to read a document are on small screens of handheld devices. For example, the typical Blackberry has a 3"x2" screen with a resolution something like 320x240 pixels.
