KEY, Judge: A general court-martial composed of officer members convicted Appellant, contrary to his pleas, of one specification of receiving child pornography in violation of Article 134, Uniform Code of Military Justice (UCMJ), 10 U.S.C. United States v. Buford, No. ACM 39538

§ 934. 1,2 The court-martial sentenced Appellant to a dishonorable discharge, confinement for six months, total forfeiture of pay and allowances, reduction to the grade of E-1, and a reprimand. The convening authority reduced the confinement to five months and one day, but otherwise approved the sentence as adjudged. On appeal, Appellant raises four issues through counsel: (1) whether the evidence was legally and factually sufficient to support his conviction; (2) whether the military judge erred by admitting videos of child pornography which were not found on Appellant’s computer; (3) whether the military judge erred by not providing the court members a definition of “receiving;” and (4) whether the transcript is not verbatim. Appellant personally raises two addi- tional issues: (5) whether the court-martial had jurisdiction over him; and (6) whether he was subjected to illegal pretrial punishment in violation of Article 13, UCMJ, 10 U.S.C. § 813. 3 Finding no error prejudicial to the substantial rights of Appellant, we affirm.

I. BACKGROUND Appellant was charged with knowing receipt via the Internet of two vide- os containing child pornography. These videos, however, were never found on any electronic devices or storage media seized from Appellant. At trial, the Government admitted and played two videos retrieved from law enforcement archives, asserting Appellant had downloaded the same videos from some other source. The Government’s case against Appellant focused on evidence indicating he had used peer-to-peer networking software to download the videos; the members convicted Appellant of receiving only one of the videos. Appellant came to the attention of military law enforcement in the sum- mer of 2014 when an Okinawa-based Naval Criminal Investigative Service (NCIS) agent, Special Agent WV, identified an Internet Protocol (IP) address

(2016 MCM). 2 The members convicted Appellant by excepting out certain language from the speci- fication and acquitted him of a separate specification of possessing child pornogra- phy, which we will discuss in this opinion. 3 Appellant personally asserts these two issues pursuant to United States v. Grostefon, 12 M.J. 431 (C.M.A. 1982).

associated with a military installation in Japan that appeared to be either transmitting or receiving child pornography via peer-to-peer networking. 4 According to expert testimony elicited by the Government at trial, peer-to- peer networking allows users to share files with each other by creating a network of the users’ computers. Unlike a server-based network, the files re- side on the individual users’ computers (“host” computers), not on centralized servers. In order for a user to be part of a peer-to-peer network, the user must first install peer-to-peer networking software which facilitates access to the network. A user on the network interested in downloading files would then look for the desired files—typically done by utilizing a search function built into the software, specifying key words for the software to seek out on the network. The software will return a list of relevant files found on the net- work, and the user can then choose which files to download to his or her com- puter. To increase the efficiency of the network, peer-to-peer software often downloads segments of a requested file from a number of different hosts on the network, then assembles those segments into a completed file on the re- questing computer. In order for this process to work, the network software creates a unique identifier known as a “hash value” for each file on the net- work. Sometimes referred to as “digital fingerprints,” hash values are derived from mathematical processes based upon the data within a particular file, unrelated to file identifiers such as filenames and extensions. 5 Unique hash values are critical for the operation of peer-to-peer networks, as the network software must use identical files in order to be able to download file segments from multiple sources at once and then correctly compile those segments into a working file. When a user installs peer-to-peer networking software on his or her com- puter, the software creates an empty folder for shared files. The folder is typi- cally visible to other network users and serves dual purposes. The first is as a repository for the user’s files which are available to others on the network to download. The second is as a destination for the files the user has requested to be downloaded. Users have the ability to move files in and out of their shared folder at their discretion. The default setting for most peer-to-peer

4 Appellant’s trial originally commenced in January 2016, but for reasons not perti- nent here, those charges were dismissed, and new charges were preferred in the lat- ter half of 2017. 5 In this case, one of the Government’s expert witnesses testified that hash values are “[t]rillions of times more accurate than DNA” in identifying unique files.

programs is to make files in the shared folder available to be downloaded by other users on the network. Thus, when a user downloads a file using the network software, the file will typically be hosted on that user’s computer for others to find and download until the user removes the file from the shared folder. Special Agent WV was alerted to the activity involving the IP address in Japan by using automated software that scans peer-to-peer networks by peri- odically searching for terms associated with child pornography. Once the software finds a computer hosting files with filenames indicative of child por- nography, the software executes a “browse-host” command, which displays the files in that host computer’s shared folder. The software logs information about the shared folder’s files in a database, including: the IP address associ- ated with the computer where the files were found, the files’ names, their hash values, and the percentage of the files on the host computer at the time the browse-host command is executed.
