Just FYI.

District Court Holds that Running Hash Values on Computer Is A Search: The case is United States v. Crist, 2008 WL 4682806 (M.D.Pa. October 22 2008) (Kane, C.J.). It's a child pornography case involving a warrantless search that raises a very interesting and important question of first impression: Is running a hash a Fourth Amendment search? (For background on what a "hash" is and why it matters, see here).

First, the facts. Crist is behind on his rent payments, and his landlord starts to evict him by hiring Sell to remove Crist's belongings and throw them away. Sell comes a cross Crist's computer, and he hands over the computer to his friend Hipple who he knows is looking for a computer. Hipple starts to look through the files, and he comes across child pornography: Hipple freaks out and calls the police. The police then conduct a warrantless forensic examination of the computer:

In the forensic examination, Agent Buckwash used the following procedure. First, Agent Buckwash created an "MD5 hash value" of Crist's hard drive. An MD5 hash value is a unique alphanumeric representation of the data, a sort of "fingerprint" or "digital DNA." When creating the hash value, Agent Buckwash used a "software write protect" in order to ensure that "nothing can be written to that hard drive." Supp. Tr. 88. Next, he ran a virus scan, during which he identified three relatively innocuous viruses. After that, he created an "image," or exact copy, of all the data on Crist's hard drive.

Agent Buckwash then opened up the image (not the actual hard drive) in a software program called EnCase, which is the principal tool in the analysis. He explained that EnCase does not access the hard drive in the traditional manner, i.e., through the computer's operating system. Rather, EnCase "reads the hard drive itself." Supp. Tr. 102. In other words, it reads every file-bit by bit, cluster by cluster-and creates a index of the files contained on the hard drive. EnCase can, therefore, bypass user-defined passwords, "break down complex file structures for examination," and recover "deleted" files as long as those files have not been written over. Supp. Tr. 102-03.

Once in EnCase, Agent Buckwash ran a "hash value and signature analysis on all of the files on the hard drive." Supp. Tr. 89. In doing so, he was able to "ingerprint" each file in the computer. Once he generated hash values of the files, he compared those hash values to the hash values of files that are known or suspected to contain child pornography. Agent Buckwash discovered five videos containing known child pornography. Attachment 5. He discovered 171 videos containing suspected child pornography.

One of the interesting questions here is whether the search that resulted was within the scope of Hipple's private search; different courts have approached this question differently. But for now the most interesting question is whether running the hash was a Fourth Amendment search. The Court concluded that it was, and that the evidence of child pornography discovered had to be suppressed:

The Government argues that no search occurred in running the EnCase program because the agents "didn't look at any files, they simply accessed the computer." 2d Supp. Tr. 16. The Court rejects this view and finds that the "running of hash values" is a search protected by the Fourth Amendment.

Computers are composed of many compartments, among them a "hard drive," which in turn is composed of many "platters," or disks. To derive the hash values of Crist's computer, the Government physically removed the hard drive from the computer, created a duplicate image of the hard drive without physically invading it, and applied the EnCase program to each compartment, disk, file, folder, and bit.2d Supp. Tr. 18-19. By subjecting the entire computer to a hash value analysis-every file, internet history, picture, and "buddy list" became available for Government review. Such examination constitutes a search.

I think this is generally a correct result: See my article Searches and Seizures in a Digital World, 119 Harv. L. Rev. 531 (2005), for the details. Still, given the lack of analysis here it's somewhat hard to know what to make of the decision. Which stage was the search — the creating the duplicate? The running of the hash? It's not really clear. I don't think it matters very much to this case, because the agent who got the positive hit on the hashes didn't then get a warrant. Instead, he immediately switched over to the EnCase "gallery view" function to see the images, which seems to be to be undoudtedly a search. Still, it's a really interesting question.

This is a quick and dirty video documentary of the things that when on around the talks and event at Phreaknic 12 (2008). Don't watch if you get sick at shaky cam movies like Blair Witch or Cloverfield. A rough timeline of the content in the video is as follows:

        Intro and leaving Louisville with Brian. Morgellon talks about hacking the Arduino micro controller platform. Sorteal talks about the LiVes Open Source video editor. AT&T Batman building by night. Mojo-JoJo soldering some stuff for the shooting range. The patron gods of hackerdom. Registration. Con swag overview. Morgellon  gets his discreet logic on. AK-47 building with HandGrip and Buttstock. Froggy talks up Notacon, which I plan to go to next year. Skydog explains the Jware chair toss event, and then we compete. Rootwars hacker wargames. I ask Int80 about using his nerdcore music in some of my videos. NotLarry explains rootwars. Some iPhone hacking with Lee Baird and John Skinner. I do a little Bluecaseing/Warnibbling with the Bluetooth on my Nokia n810. John, Lee, Brian and I go to the German restaurant. I blind DOSman with the light from my camera and check out what folks are doing with the Arduinos Droops brought for folks to play with. I check back in on R00tW4rz. I blind Droops. I talk Ettercap filters with operat0r. USB door key fun with the Arduino. More breadboard fun. Nokia n810 + Ettercap Filter + Lemon-part = win. Int80 gets down with his own bad self, and the rest of Phreaknic. I find an energy drink with protein. Folks play with the hardware keyloggers I brought, and we have some epic fail with the IBM Model M + USB adapter + Mac OS 10.5. Winn Schwartau joins in on the keylogger fun. DOSman and Zack use a directional antenna from the 9th floor to search downtown Nashville for WiFi access points. Zoom in on Al. John and Lee eat jerky. Daren and Shannon from Hak5 blind me this time. :) Then they do a quick interview. I interview TRiP about the legalities of wardriving, sniffing and leaving your access point open so you have plausible deniability of copyright infringement (most likely it won't hold water in court if you are a computer geek). I give Hak5 Daren beef jerky. Ziplock had more con badges than God. I meet up with Iridium. I talk with Nightcarnage about the audio/video setup at Phreaknic. As I predicted, the Potters won the WiFi Race. I say why this was the best Phreaknic ever. Using green lasers on crack dealers. Techno in the dark, the Aiptek action HD does not do well in low light. Nicodemius shows off his Minority Report like multi-touch table. Hula hoop contest. I check back in with Jeff Cotton and his USB keyed door. I strap on my gear to leave the con. Brian and I do a wrap up of our thoughts on Phreaknic 2008.
