ORDER
The Department of Defense (“DOD”) appeals from a judgment of the United States District Court for the Southern District of New York (Rakoff, /.)granting the Associated Press (“AP”) summary judgment in large part and ordering DOD to disclose (1) detainee identifying information contained in records of DOD’s investigations of detainee abuse at Guantanamo Naval Bay in Cuba by United States military personnel and by other detainees, and (2) identifying information of detainees family members contained in personal letters to two detainees submitted to an Administrative Review Board, based on the district court’s finding that the privacy *279 exemptions in the Freedom of Information Act (“FOIA”) did not apply. We hold that the detainees and their family members do have a measurable privacy interest in their identifying information and that the AP has failed to show how the public interest would be served by disclosure of this information. We conclude that the identifying information is exempt from disclosure under the FOIA privacy exemptions.
REVERSED.
OPINION
The Department of Defense (“DOD”) appeals from a judgment of the United States District Court for the Southern District of New York (Jed S. Rakoff, J.) granting the Associated Press (“AP”) summary judgment in large part and ordering DOD to disclose identifying information of Guantanamo Bay detainees contained in DOD records documenting allegations of abuse by military personnel and by other detainees, and identifying information of family members contained in personal letters sent to two detainees and submitted by those detainees to Administrative Review Boards (“ARB”) 1 pursuant to the Freedom of Information Act (“FOIA”), 5 U.S.C. § 552 (2006). The district court found that the privacy exemptions in FOIA did not protect that information from disclosure, concluding that the detainees and their family members had no cognizable privacy interest and that the public interest in disclosure was great. We hold that the detainees and their family members do have a measurable privacy interest in the nondisclosure of their identifying information in these records and that the AP has failed to show how the public interest would be further served by disclosure of their identities. We conclude that the FOIA privacy exemptions protect this information from disclosure. We reverse.
Background
This case arises out of two FOIA requests submitted to DOD by AP, seeking documents related to detainee treatment at Guantanamo Bay. The first was made on November 16, 2004, and requested, inter alia, copies of documents containing allegations or accounts of mistreatment of detainees by U.S. military personnel since January 2002, including any disciplinary action taken, and copies of documents containing allegations of detainee-against-detainee abuse. A subsequent January 18, 2005 request was made for documents related to ARB hearings, including (1) transcripts of testimony; (2) written statements and other documents provided by detainees; (3) affidavits submitted by witnesses to the ARBs; (4) allegations against the detainees; and (5) explanations of decisions made to release or transfer detainees.
AP filed a complaint on June 9, 2005 to compel DOD to produce the requested documents. DOD responded by producing 1,400 pages of documents, many of which had extensive redactions. DOD moved for summary judgment on February 23, 2006, and AP cross-moved for summary judgment on March 3, 2006. 2 By the time the *280 motions were addressed by the district court, the dispute had narrowed to four categories of redaction: (1) identifying information of detainees who allege abuse by DOD personnel, which DOD had redacted pursuant to FOIA Exemptions 6 and 7(C); 3 (2) identifying information of detainees involved in allegations of detainee-against-detainee abuse, which DOD had redacted pursuant to Exemptions 6 and 7(C); (3) identifying information of detainees in transfer-release documents, which DOD had redacted pursuant to Exemptions 5 and 6; and (4) identifying information of detainees’ family members in correspondence sent to detainees and submitted by the detainees in their ARB proceedings, which DOD had redacted pursuant to Exemptions 3 and 6.
On September 20, 2006, the district court granted AP’s motion for summary judgment in large part and denied DOD’s counter-motion, holding that AP “is entitled to nearly all the information it seeks.” First, it ruled that Exemptions 6 and 7(C) did not apply to identifying information of detainees who allege abuse by DOD personnel because “the privacy interest is *281 minimal and the public interest is great” such that “disclosure of this information would constitute neither a clearly unwarranted [under Exemption 6], nor an unwarranted [under Exemption 7(C) ] invasion of personal privacy.” At issue were eight files from investigations into detainee mistreatment by military personnel in which DOD had redacted the names and other identifying information of the detainees involved. The district court explained that Exemptions 6 and 7(C) require the court to balance the privacy interest and public interest; it found that it was “hard to see that any substantial privacy interest is involved” because the detainees’ identities were fully known to the personnel they accused and to the personnel who responded to the accusations. It further explained that detainees, like other prisoners, have minimal privacy rights, and surmised moreover that “individuals detained incommunicado without many procedural safeguards ... would want their plights, and identities, publicized.” The district court based the latter conclusion on the fact that three former detainees had issued a report in 2004 alleging that they had been beaten and mistreated in Guantanamo; other detainees had conveyed such abuse allegations to the public through their attorneys; and still other detainees had participated in hunger strikes to protest alleged abuse. Against what it determined to be a minimal privacy interest, the district court weighed the “considerable public interest in learning more about DOD’s treatment of identifiable detainees, whether they have been abused, and whether such abuse has been properly investigated.” It found that AP had made a showing of evidence “that would warrant belief by a reasonable person that the alleged Government impropriety might have occurred.” Thus, it concluded that because the public interest is great and the privacy interest minimal, the redactions had to be removed and the identifying information disclosed.
Second, the district court concluded that identifying information of detainees involved in allegations of detainee-against-detainee abuse did not fall under Exemptions 6 and 7(C). The documents at issue were reports of allegations of detainee-against-detainee abuse recorded by military personnel. In considering the privacy interest of the detainees, the district court first found that the interest of the detainees alleging abuse was minimal because their purpose in making the allegations was “to bring them to light.” Although the court commented that the privacy interest of detainees against whom allegations of abuse were made “might be slightly more weighty,” it reiterated that prisoners have modest privacy rights. The district court also pointed out that the government had “failed to make a particularized showing of why any given one of [the detainees] has a material privacy interest in keeping his identity secret.” It therefore concluded that any privacy interest was “substantially outweighed by the public interest in knowing more about the context in which DOD was called upon to evaluate the allegations,” reasoning further that this inquiry could only be explored if the particulars about the person whose conduct was in question were known. Specifically, the district court explained that without the names, AP would not know the detainees’ nationalities or religions; without that information it would be impossible to scrutinize DOD’s conduct.
Third, the district court found that identifying information of detainees in transfer-release documents did not fall under Exemptions 5 and 6 and must be dis *282 closed. 4 The district court reasoned that Exemption 5, which exempts “inter-agency or intra-agency memorandums or letters which would not be available by law to a party other than an agency in litigation with the agency,” 5 U.S.C. § 552(b)(5), did not apply to the transfer-release documents because they do not fall within the scope of the deliberative process privilege. It also concluded that Exemption 6 did not apply because the government did not offer more than “conclusory speculation” that disclosure of the information could subject detainees and their family members to harm.
On the final issue, the district court held, with one exception, that the redacted identifying information of detainees’ family members contained in their letters submitted by the detainees at their ARB proceedings, did not fall under Exemptions 3 or 6. Exemption 3 protects from disclosure matters that are “specifically exempted from disclosure by statute ... provided that such statute (A) requires that the matters be withheld from the public in such a manner as to leave no discretion on the issue, or (B) establishes particular criteria for withholding or refers to particular types of matters to be withheld.” 5 U.S.C. § 552(b)(3). The district court reasoned that while 10 U.S.C. § 130c is an applicable withholding statute, 5 the documents did not arguably or logically fall within its scope and thus did not fall under Exemption 3.
As to Exemption 6’s applicability to the family members’ identifying information, the district court found this to be “a closer call.” In its previous decision in
Associated Press v. U.S. Dep’t of Def,
DOD appeals from the district court’s decision, but challenges only its rulings with respect to (1) redaction of identifying information in records relating to allegations of detainee mistreatment and detainee-against-detainee abuse; and (2) redaction of identifying information of detainees’ family members.
Discussion
Standard of Review
We review
de novo
the district court’s grant of summary judgment in a FOIA case.
Wood v. FBI,
Applicable Law
FOIA was enacted “to facilitate public access to Government documents,”
U.S. Dep’t of State v. Ray,
Detainees’ Identifying Information — Exemption 7(C)
Exemption 7(C) exempts from disclosure “records or information compiled for law enforcement purposes” when production of such records or information “could reasonably be expected to constitute an unwarranted invasion of personal privacy.” 5 U.S.C. § 552(b)(7)(C). Exemption 7(C) requires a court to “balance the public interest in disclosure against the [privacy] interest Congress intended the Exemption to protect.”
U.S. Dep’t of Justice v. Reporters Comm.,
We have said that “FOIA requires only a measurable interest in privacy to trigger the application of the disclosure balancing tests.”
Fed. Labor Relations Auth.,
As for the public interest against which the privacy interest is to be weighed, the Supreme Court has made clear that there is only one relevant interest, namely, “to open agency action to the light of public scrutiny.”
Reporters Comm.,
Where the privacy concerns addressed by Exemption 7(C) are present, the exemption requires the person requesting the information to establish a sufficient reason for the disclosure. First, the citizen must show that the public interest sought to be advanced is a significant one, an interest more specific than having the information for its own sake. Second, the citizen must show the information is likely to advance that interest. Otherwise the invasion of privacy is unwarranted.
Nat’l Archives & Records Admin. v. Favish,
With these standards in mind, we turn to the specific redactions at issue in this case. The first two sets of documents at issue are (1) eight files containing récords documenting allegations of detainee abuse by military personnel;
10
and (2) docu
*286
ments containing reports of allegations of detainee-against-detainee abuse. In both sets of documents, DOD redacted all identifying information of the detainees involved, asserting that it did so to protect the detainees’ personal privacy pursuant to Exemptions 6 and 7(C). As a preliminary matter, it is undisputed that these documents were “compiled for law enforcement purposes” so as to fall under Exemption 7(C). Indeed, the records were compiled to document allegations of abuse and to impose disciplinary sanctions against military personnel and detainees where appropriate.
See Am. Civil Liberties Union v. Dep’t of Def.,
(1) Privacy Interest
We consider whether the detainees have any privacy interest in the nondisclosure of their names and identifying information in the records containing allegations of abuse by military personnel and by other detainees. That interest need only be more than
de minimis
to trigger the application of the balancing test to determine whether disclosure is permitted under FOIA.
See Fed. Labor Relations Auth.,
The privacy interest protected by Exemption 7(C) is an interest in “avoiding disclosure of personal matters” and “keeping personal facts away from the public eye.”
Reporters Comm.,
Each of these concerns is involved in this case. We first consider the detainees who allegedly have been abused by military personnel or other detainees. Certainly they have an interest in both keeping the personal facts of their abuse from the public eye and in avoiding disclosure of their identities in order to prevent embarrassment. As victims of abuse, they are entitled to some protection of personal information that would be revealed if their names were associated with the incidents of abuse. The disclosure of their names could certainly subject them to embarrassment and humiliation.
We disagree with the district court’s conclusion that the detainees who allegedly have been abused do not have any substantial privacy interest because they, like prisoners, have little reasonable expectation of privacy. Although the detainees here are indeed like prisoners, their Fourth Amendment reasonable expectation of privacy is not the measure by which we assess their personal privacy interest protected by FOIA. Rather, the privacy interest for purposes of Exemption 7(C) is broad and encompasses “the individual’s control of information concerning his or her person.”
Reporters Comm.,
*288 Second, we consider the detainees who are alleged to have abused other detainees. Even more so than the victims of this alleged abuse, these alleged abusers have a significant privacy interest in keeping their identities undisclosed. It is likely that identifying them could subject them to embarrassment and humiliation. The district court acknowledged that “the privacy interests of the detainees about whom the allegations were made might be slightly more weighty,” but ultimately found that as prisoners, their privacy rights “are extremely modest.” Again, we disagree with the district court’s finding in this regard and conclude that the detainees accused of abusing other detainees have a measurable privacy interest that triggers Exemption 7(C)’s protection of their identifying information.
(2) Public Interest
Having established that the detainees have a measurable privacy interest in the nondisclosure of their names and other identifying information, we turn to the question of whether disclosure of that information would further the public interest such that disclosure would be a warranted invasion of the detainees’ personal privacy.
See Reporters Comm.,
The Supreme Court has made it clear that once a privacy interest is identified, disclosure is unwarranted under Exemption 7(C) unless the requester can show a “sufficient reason for the disclosure.” Fav
ish,
AP asserts three arguments as to how the public interest would be served by disclosure of the detainees’ names and identifying information: (1) the information is necessary to provide context for DOD’s response to the abuse allegations because it would allow the public to know the detainees’ nationalities and religions; (2) the information would allow the public to evaluate DOD’s other actions with respect to these detainees, including transfer and release decisions; and (3) the information would allow the public to seek out the detainees’ side of the story. For the reasons that follow, we conclude that these arguments are unavailing and that at most disclosure would only modestly further the public interest. That is, any public interest served by such disclosure is significantly outweighed by the detainees’ privacy interest.
AP’s first argument appears to suggest that the alleged government impropriety in handling these allegations of various abuses may be tied to the nationalities or religions of the detainees involved. In essence, AP implies that DOD may have responded differently to allegations of abuse depending on the nationalities or religions of the abused detainees. Without that underlying assumption, knowing the detainees’ nationalities or religions would not serve the public interest because it would shed no light on what the government is up to. AP’s argument in this regard is squarely foreclosed by Favish, in which the Supreme Court held:
[W]here there is a privacy interest protected by Exemption 7(C) and the public interest being asserted is to show that responsible officials acted negligently or otherwise improperly in the performance of their duties, the requester must establish more than a bare suspicion in order to obtain disclosure. Rather, the requester must produce evidence that would warrant a belief by a reasonable person that the alleged Government impropriety might have occurred.
Favish,
AP’s second argument, that the names and identifying information would allow the public to track these detainees’ treatment in other aspects of DOD actions, including transfer and release decisions, deserves more attention. If the public knew which specific detainees were involved in the allegations of abuse by military personnel and by other detainees, then it would be possible to see whether *290 the detainees’ involvement in those alleged abuses affected how they were otherwise treated throughout various administrative procedures. Pursuant to the particular FOIA requests at issue in this case, DOD released documents relating to ARB hearings where the government determined whether the detainees should be released, transferred to the custody of another government, or further detained. Thus, if the identities of the detainees involved in the abuse allegations were known, it might be possible to see whether those allegations affected the government’s decision to transfer, release, or continue to detain them. Although under this rationale the public interest might be further served, the speculative nature of the result is insufficient to outweigh the detainees’ privacy interest in nondisclosure.
AP’s third argument, that the information will alloys the public to seek out the detainees’ side of the story, calls upon a “derivative use” theory.
See Ray,
Although this Court has not addressed the issue of whether a derivative use theory is cognizable under FOIA as a valid way by which to assert that a public interest is furthered, we have indicated that it may not be.
See Hopkins,
We need not decide today whether a derivative use theory would ever justify the release of personal information because we find that the privacy interest of the detainees in nondisclosure of their names and identifying information is not outweighed by any minimal public interest that might be served by such disclosure. Disclosure of this information is, therefore, exempted under Exemption 7(C) because such disclosure “could reasonably be expected to constitute an unwarranted invasion of personal privacy.” Because we find
*291
that Exemption 7(C) applies to the redactions of detainees’ identifying information, we do not need to address the applicability of Exemption 6.
Reporters Comm.,
Family Members’ Identifying Information — Exemption 6
Exemption 6 exempts from disclosure “personnel and medical files and similar files the disclosure of which would constitute a clearly unwarranted invasion of personal privacy.” 5 U.S.C. § 552(b)(6). To determine whether identifying information may be withheld pursuant to Exemption 6 we must: (1) determine whether the identifying information is contained in “personnel and medical files and similar files;” and (2) balance the public need for the information against the individual’s privacy interest in order to assess whether disclosure would constitute a clearly unwarranted invasion of personal privacy.
Wood,
The second set of documents at issue are personal letters sent to two detainees, Detainee b(l) and Detainee b(2), from their family members through the Red Cross. These Red Cross Messages (“RCMs”) were submitted to DOD by the detainees at their ARB hearings. DOD redacted the names and addresses of the detainees’ family members in these letters pursuant to FOIA Exemptions 3 and 6. Preliminarily, we note that the parties do not dispute that the letters at issue are considered “personnel and medical files and similar files” within the meaning of Exemption 6. Although the government does not indicate the specific category into which the family members’ letters fall, it appears that “similar files” would be the closest description. The phrase “similar files” has a broad meaning and encompasses the government’s “records on an individual which can be identified as applying to that individual.”
See U.S. Dep’t of State v. Washington Post Co.,
We now consider whether the family members of Detainee b(l) and Detainee b(2) have more than a de minimis privacy *292 interest in the disclosure of their names and addresses.
(1) Privacy Interest
The Supreme Court indicated that “privacy encompass[es] the individual's control of information concerning his or her person,”
Reporters Comm.,
The district court ordered disclosure of the family members’ names and addresses except for Detainee b(2)’s wife reasoning that she retained a reasonable expectation of privacy in her identifying information such that it was withheld properly under Exemption 6. For the reasons noted above, we disagree with the district court that determining whether a person has a reasonable expectation of privacy is the manner by which to analyze the person’s privacy interest under Exemption 6.
The government contends the family members have a substantial privacy interest in avoiding disclosure of their identifying information because that disclosure “could place the family members at risk of harm based on their connection to detainees who provided testimony to the ARBs that DOD believes is likely to be perceived by the Taliban (including former associates of one detainee) as hostile, or even traitorous.” According to DOD, the testimony of the two detainees at their ARB hearings, which appears “cooperative with the United States and hostile or disloyal to the Taliban, could subject the detainees’ family members to retaliation.”
We emphasize that “the focus, in assessing a claim under Exemption 6, must be solely upon what the requested information
reveals,
not upon what it might lead to.”
Ray,
(2) Public Interest
“Goals other than opening agency action to public scrutiny are deemed unfit to be accommodated under FOIA when they clash with privacy rights.”
Fed. Labor Relations Auth.,
AP contends that the “public has a strong interest in evaluating whether DOD properly followed-up on [the detainees’ mistaken identity] claims.” DOD counters that the “names and addresses of family members contained in their personal letters to detainees reveal nothing about DOD’s action. The only conceivable value of those names is to provide ÁP with leads for investigating the detainees’ claims.” We agree with DOD. We do not see and AP failed to explain how revealing the family members’ names and addresses would inform the citizens about “what their government is up to.”
See Ray,
Conclusion
We hold that identifying information of the detainees in the records documenting allegations of abuse and identifying information of detainees’ family members in letters submitted to the government are exempt from FOIA disclosure under Exemptions 7(C) and 6 respectively. The judgment of the district court is REVERSED.
Notes
. The Administrative Review Board was established to assess annually the need to continue to detain each enemy combatant during the course of the current and ongoing hostilities. This administrative review permits each enemy combatant in the control of DOD at Guantanamo Bay Naval Base to explain why he is no longer a threat to the United States and its allies in the ongoing armed conflict against Al Qaida and its affiliates and supporters or to explain why his release would otherwise be appropriate.
. Although the docket and Joint Appendix reflect that DOD first moved for summary judgment and AP subsequently cross-moved for *280 summary judgment, in its order the district court stated that: "AP's motion for summary judgment is hereby granted, and DOD’s counter-motion denied.”

(3) specifically exempted from disclosure by statute (other than section 552b of this title), provided that such statute (A) requires that the matters be withheld from the public in such a manner as to leave no discretion on the issue, or (B) establishes particular criteria for withholding or refers to particular types of matters to be withheld;
(4) trade secrets and commercial or financial information obtained from a person and privileged or confidential;
(5) inter-agency or intra-agency memorandums or letters which would not be available by law to a party other than an agency in litigation with the agency;

(1) That the information was provided by, otherwise made available by, or produced in cooperation with, a foreign government or international organization.
(2) That the foreign government or international organization is withholding the information from public disclosure (relying for that determination on the written representation of the foreign government or international organization to that effect).
(3) That any of the following conditions are met:
(A) The foreign government or international organization requests, in writing, that the information be withheld.
(B) The information was provided or made available to the United States Government on the condition that it not be released to the public.
(C) The information is an item of information, or is in a category of information, that the national security official concerned has specified in regulations prescribed under subsection (f) as being information the release of which would have an adverse effect on the ability of the United States Government to obtain the same or similar information in the future.
