Barely a month goes by without some newly uncovered fraudulent image making it into the news. In February, for instance, an award-winning photograph depicting a herd of endangered Tibetan antelope apparently undisturbed by a new high-speed train racing nearby was uncovered to be a fake. The photograph had appeared in hundreds of newspapers in China after the controversial train line was opened with much patriotic fanfare in mid-2006. A few people had noticed oddities immediately, such as how some of the antelope were pregnant, but there were no young, as should have been the case at the time of year the train began running. Doubts finally became public when the picture was featured in the Beijing subway this year and other flaws came to light, such as a join line where two images had been stitched together. The photographer, Liu Weiqing, and his newspaper editor resigned; Chinese government news agencies apologized for distributing the image and promised to delete all of Liu’s photographs from their databases.
In that case, as with many of the most publicized instances of fraudulent images, the fakery was detected by alert people studying a copy of the image and seeing flaws of one kind or another. But there are many other cases when examining an image with the naked eye is not enough to demonstrate the presence of tampering, so more technical, computer-based methods—digital image forensics—must be brought to bear.

-Fraudulent photographs produced with powerful, commercial software appear constantly, spurring a new field of digital image forensics.
-Many fakes can be exposed because of inconsistent lighting, including the specks of light reflected from people’s eyeballs.
-Algorithms can spot when an image has a “cloned” area or does not have the mathematical properties of a raw digital photograph.

It is not always simple to recognize these. It is especially difficult when the same fictitious entry is reprinted and adapted by multiple reference works. In such cases, the multiple sources serve to bolster the entry's authenticity, so that many come to believe that they are reading a factual article. Uncovering fictitious entries is a part of the game for editors and publishers. In some cases, the game can extend beyond a single work, as an academic parody or a satire is reproduced, quoted, or otherwise extended into multiple publications such as encyclopedias or science periodicals. One can only speculate about fictitious entries that go undiscovered, especially once a work becomes very old. Katharina Hein writes, "Insiders assume that every encyclopedia contains wrong keywords." There is great stylistic variance in fictitious entries: some are simple parodies that are easily seen through, but others are carefully constructed pastiches that imitate factual entries so well that they are very difficult to detect. Fictitious entries normally follow the same structure as a standard entry: biographies have a structure that is particularly identifiable, and therefore false biography articles are the most common type of fictitious entries.
