Can everything be faked? Digital editing and manipulated data

     Spoiler alert -- once upon a time (in 1993) a murder mystery movie was released called "Rising Sun". Part of the evidence was a digital video of an area which presumably was the time/space where a murder took place. It turned out that the digital video was edited (but not quite carefully enough) to fake the evidence.
     In 1993 (25 years ago as of the writing of this blog), this was relatively new to ponder. We knew that photos could be doctored/changed/altered but, in this movie, a central point was that digital video could also be changed. (Once changed digitally, film copies could be made if desired.) Twenty-five years ago, this took a lot of time and many computers. Doing such a thing still requires a lot of processing power but that power is now available on many home computers (or even phones or tablets).
     We are seeing this capability ad nauseum within the social media. Within less than 24 hours, a new set of memes, photos, and sometimes videos are released purporting to prove something or call something out. Some are real. Sometimes it is obvious (quotes from Lincoln about the Internet SHOULD be immediately recognized as fake although I have found that a lot of people tend to believe them) but often it is not. Sometime the source is a public satire, or irony, site and "should" be recognized as such by those that read them -- but they often aren't. This happens on all segments of the political spectrum.
     An awful lot (too much) of the time, a forgery is only discovered to have taken place by recreating how the fake was created (such as finding the original photos that have been merged together).
     The foundation problem is that if it CAN be faked, how does one determine the primary reality for this particular universe? For articles and "news" segments, it is possible to research multiple sources, find a general agreement from various sources and determine with a high probability (but not 100%) what the reality is. What does one do about forged supporting documents? It is not easy, but it is possible, to find component parts from various photos, videos, sound recordings, and such to be reasonably sure that something has been compiled together, and manipulated, into a different item -- a "photoshopped" photo, an edited sound recording, and so forth.
      However, we are reaching the point of being able to synthesize (or create) from scratch whatever we want. Computer-Generated Imagery (CGI) has gotten so good that, for films, they sometimes deliberately make it appear less real because people can be annoyed if they think it is "real" when it isn't; they like to know it is CGI. That objection doesn't apply when the person, or group, creating the artifact WANTS to have it be accepted as real.
     As per previous blogs, this doesn't just apply to distorting current things of interest -- it can also be applied to faking history and re-inventing the past. Nor (as per other previous blogs) can we rely on memory to be sure. There are those who do not remember what was said by a politician the previous day.
     So, to attempt to answer the question posed in the subject -- can everything be faked? Probably so. As is true that social change falls behind that of technological changes, our ability to create fake items is overwhelming our ability to prove that it has been done. What methods of verification do you use? What can be done to more easily separate the close-to-true from the false? Is this just a new reality that we need to accept and learn to deal with?

The Foundations of History Tend to Shake: could the Holocaust fade away?

     The last of the surviving veterans of World War II are making their passage from this world. Also, the last of the survivors of the Holocaust. Together, this means that -- out of the many thousands of direct and indirect witnesses to the atrocities of the Holocaust -- very few remain and soon there will be none still alive.
     So, why does that make a difference? It is recorded in history and references are still taught and read. It happened, has been very well documented and proven, and is a tragedy from which we can learn for many years. Right?
     Alas, such is not necessarily the case. History is always in the process of being rewritten. Sometimes it is a result of more information coming to light -- excavations, first-hand documents, physical proofs and artifacts. Sometimes it is a matter of documents and artifacts being lost or deliberately destroyed or suppressed and then denied.
     At its best, history is a tiny slice of what has happened at a particular time. Choices are made as to what to include and what to omit.  History, or "His story", tends to focus on males throughout history -- such that women's accomplishments are forgotten, overlooked, or attributed to men associated with them. Histories are also "written by the winners" and the losers of wars and other confrontations often have their records destroyed or omitted -- certainly they are de-emphasized. Also, the history writers make choices from the materials available. Who, and what, is "important"? Do they talk about the war leader or do they talk about the woman organizing and leading the cooks to feed the army (or the family)? Is the life of the baker considered to be as important as the Duke? Do the details of the life of a peasant get equal emphasis to that of the local feudal lord? Even during peacetime, the accounts and records will be more in depth for those of the ruling segments.
     At its worst, history can become fantasies to support the current people in power. Perhaps out of shame, genocides, massacres, and evils done by humans to other humans (such as slavery) have a great tendency to be obscured or their realities warped. Some people try to "clean" history -- change the language used within books, change scenarios and such so that it meets present-day standards. That is also a method of falsifying history. A third category is to deliberately create fake documentation to support misinformation that the person, or group, would like to present as the truth.
     A very active and well-known Anti-Semite wrote a "scholarly" book concerning his anti-semitism. At first reading, it looks very well-researched, objective, and persuasive. It is not until the "references" are further checked that the fabrication becomes clear. The references are "circular references". The references are to people and their works who then refer back to the author or to other people to whom he references. In other words, the work supports itself by having a group of people wanting to present a falsified world view support, and "authenticate", each other. There is no connection to real world events or first-hand accounts. It is all a built up fantasy that SOUNDS like it has a basis in fact.
     So, with history's inherent limitations and vulnerability to falsification, how CAN valid history be protected? To quote Pilate, from the book of John, "What is truth?"
     There isn't an easy answer. History can never present the full truth -- it is inherently limited by access to, and choices from, data. Constant vigilance is needed to prevent deliberate, unsubstantiated, changes to history and acceptance of falsified data. The primary defense that exists is a solid educational background for the general citizenry -- to allow them to judge, to research, and to understand (such as going deeply enough to locate circular references).
