![]() In the arena of commercial sexual exploitation of children, law enforcement concerns involve the use of steganography by manufacturers and distributers of child pornography to exchange and to hide child pornography.Consider the following hypothetical scenario. Unlike cryptography, which merely obscures the communication between two parties when observed by a third party, steganography hides the very existence of the communications channel. The concern in law enforcement, of course, is that steganography is being used to “protect” communication amongst members of a criminal conspiracy. Steganalysis is the detection and recovery of that hidden information - and is the role of the computer forensics examiner for both law enforcement and anti-terrorism investigations. The original file that will contain the hidden information is called the carrier medium the modified carrier file that contains the hidden information is called the steganographic medium. ![]() Modern steganographic applications in the digital realm provide a covert communications channel by hiding some type of binary data in another file. Historically, steganographic methods date back thousands of years and include the use of invisible ink, microdots, and tattooing the scalps of slaves. Steganography is often referred to colloquially as “stego ” for example, references to “stego” software are common.Īs previously described in an NCPCA UPDATE four years ago, 2 “ Steganography: Hidden Images, A New Challenge in the Fight Against Child Porn,” steganography provides the means whereby two parties can communicate in such a way that a third party is not aware of the secret communication. ![]() Note all require signup.“Steganography,” my colleague asked, “is that a dinosaur or an icicle hanging down in a cave?” Steganography is the science of “covered writing” and is one of the newer tools in the arsenal of the cybercriminal and cyberterrorist - or any moderately computer-astute user. You might also consider using web-clipper or bookmarking type services' provided extensions like (in rough order of similarity) OneNote, Notion, Evernote, or raindrop.io. Pocket (requires signup/login with FF account) is included natively in the browser and may also work for your purposes if you're willing to type out a short tag name for the collection you want a tab to go to upon saving (a little more bookmark-like, clearly, but works for my reading-list assembling purposes). The only caveat I should mention using it from a collections standpoint is that adding tabs to a stash from sidebar after creating that stash hides the tab from view by default, which may be annoying depending on your use case-you can hold the Alt key while clicking the save tab button to avoid this behavior, or you can click the down arrow in the top right corner of the tab bar to restore them. You can also add tabs to the same collection later from the with the buttons below the collection title in the sidebar menu. It allows you to save all the open tabs as a collection w/ one click or shift-click on specific tabs to select them and then right click > Tab Stash > Stash Tabs to save those tabs as a collection. Tab Stash might work for this purpose, though a little rough on the edges.
