OPINION
Plаintiff-appellant, a prisoner in the custody of the Ohio Department of Rehabilitation and Correction, challenges the constitutionality of Ohio’s DNA Act, which requires the collection of DNA specimens from convicted felons. Below, plaintiff sought declaratory and injunctive relief, contending that the Act is violative of his Fourth Amendment, Fifth Amendment, due process and equal protection rights. The district court awarded summary judgment to the defendants on all claims. Finding the district court’s opinion to be well-reasoned and consistent with the growing body of case law on such challenges to DNA statutеs, we affirm.
I. FACTUAL AND PROCEDURAL BACKGROUND
Plaintiff-appellant Antoine D. Wilson is an African-American from Columbus, Ohio. After being found guilty of felonious assault in June 1998, he was sentenced to seven years’ imprisonment, to run concurrently with a three-year term imposed on a firearm specification. Section 2901.07 of the Ohio Revised Code (“DNA statute” or “the Act”), in its present form, requires that a person convicted of a felony who is sentenced to a prison term “shall submit to a DNA [deoxyribonucleic acid] specimen collection procedure.” In October 2003, Wilson submitted, over his objection, to the collection of a DNA sрecimen by allowing officials at the Southern Ohio Correctional Facility to swab buccal cells from the inside of his cheek. Pursuant to the Act, the resultant sample was forwarded to the Ohio Bureau of Criminal Identification and Investigation (“BCI & I”) for analysis and for entry of the resultant DNA profile into the state and national DNA index systems. The DNA profile remains indefinitely in the index systems and is available *424 for use by law enforcement agencies in seeking matches with DNA evidence obtained in pending and future criminal investigations. In addition, the DNA samples collected by the Ohio Department of Rehabilitation and Correction are also stored indefinitely.
Wilson commenced this action in September 2004 by filing a five-count complaint, naming as defendants the Director of the Ohio Department of Rehabilitation and Correction, the Superintendent of the BCI & I, the Ohio Attorney General, and the wardens of correctional facilities where Wilson has been incarcerated. Wilson proceeds under 42 U.S.C. § 1983, alleging that the collection and maintenance of his DNA sample and the recording of his DNA profile violate his constitutional rights. By consent of the parties, the ease was referred to Magistrate Judge Norah McCann King for all purposes and, ultimately, for entry of judgment on the parties’ cross-motions for summary judgment.
The district court granted defendants’ motion for summary judgment in March 2007. On Count I, the court ruled that the Fourth Amendment protection against unreasonable searches and seizures is not violated because a prisoner’s diminished privacy rights are outweighed by the state’s interest in preventing, deterring and solving crimes. On Count II, the court ruled that substantive due process rights are not violated because the swabbing or extraction of saliva from a prisoner’s mouth is such a minimal intrusion as tо not implicate any fundamental right to bodily integrity. On Count III, the court held that procedural due process rights are not violated because the DNA sample collection process is attended by adequate procedural safeguards to minimize the risk of erroneous deprivation. On Count IV, the court ruled that the Fifth Amendment protection against compulsory self-incrimination is not violated because DNA samples are not testimonial in nature. Finally, on Count V, the court held that any disparate adverse impact on African-Americans, who are disproportionately ovеr-represented in Ohio prison populations, is not actionable because there is no evidence of intentional discrimination. On appeal, Wilson challenges all of these holdings. 1
II. ANALYSIS
The parties agree that this case poses no questions of fact and that the district court’s legal rulings in denying Wilson’s motion for summary judgment and granting defendants’ motion for summary judgment are subject to
de novo
review.
See Cutter v. Wilkinson,
A. Fourth Amendment Unreasonable Search and Seizure
During the last several years, the federal appellate courts have addressed a plethora of claims by prisoners, рarolees, supervised releasees and probationers, challenging the constitutionality of federal and state laws that require them to submit to collection of DNA specimens for purposes of DNA profiling. Most of these challenges have been brought as claims for violations of the Fourth Amendment protection against unreasonable search and seizure. Such Fourth Amendment challenges have been uni *425 formly rejected by the courts, as the government’s compelling interests in crime control have consistently been deemed to outweigh the plaintiffs’ diminished privacy intеrests.
Most recently, the Ninth Circuit rejected such a challenge to the federal DNA Analysis Backlog Elimination Act, as amended by the Justice for All Act.
United States v. Kriesel,
Moreover, Fourth Amendment challenges to parallel state DNA-indexing statutes have met with similar results.
See e.g., Padgett v. Donald,
Nonetheless, appellant Wilson maintains the district court erred in awarding judgment to the state defendants on his Count I Fourth Amendment claim.
1. “Totality of the Circumstances” Test or “Special Needs” Test?
Although the federal courts have reached uniform results, they have been divided regarding the most appropriate test to apply in scrutinizing a Fourth Amendment challenge to a DNA-indexing statute. Under the “totality of the circumstances” test, determining whether a search is reasonable requires “assessing, on the one hand, the degree to which it intrudes upon an individual’s privacy and, on the other, the degree to which it is needed for the promotion of legitimate governmental interests.”
Samson v. California,
Under the “special needs” doctrine, the Supreme Court has recognized that a war-rantless, suspicionless search may be justified “when special needs, beyond the normal need for law enforcement, make the warrant and probable-cause requirement impracticable.”
Griffin v. Wisconsin,
In the wake of the
Samson
ruling, in which the Supreme Court upheld a suspi-cionless sеarch of a parolee without bothering to identify any special need, courts have viewed
Samson
as affirmatively signaling that the totality-of-the-cireum-stances test is the appropriate test for assessing the reasonableness of suspicion-less DNA collection requirements as applied to parolees and supervised releasees.
Kriesel,
Wilson urges the court to apply the special-needs test, as the district court did below, but contends that the district court misapplied the test.
3
Wilson contends
Samson
should be narrowly construed as applying the totality-of-the-circumstances test in lieu of the special-needs test only under circumstances where a suspicionless search of a parolee is expressly authorized by parole agreement and by state law. The argument is expressly refuted by
Samson
itself. It is true that Samson’s pаrole agreement included a search condition that the Supreme Court viewed as demonstrating that Samson had a significantly diminished expectation of privacy as a parolee. Yet, the Court expressly declined to rest its holding on a consent rationale, expressly declined to address whether the search condition was justified as a special need, and expressly anchored its holding in general Fourth Amendment
*427
reasonableness principles.
Samson,
Accordingly, we conclude — consistent with the conclusion reached by the Ninth Circuit in Kriesel, the First Circuit in Wei-kert, and the Tenth Circuit in Banks — that the Ohio DNA statute, as applied to Wilson, is properly evaluated under the totality-of-the-circumstances test. If, per Samson, the totality of the circumstances test affords sufficient assurance of the reasonableness of a suspicionless search of a parolee, who has less diminished privacy rights than a prisoner, then it clearly affords adequate protection to the rights of a prisoner. Wilson was a prisoner when corrections officials collected his DNA sample and when the district court evaluated the merits of his claim. Now, to the extent Wilson’s Fourth Amendment claim may be considered to be premised on his slightly greater privacy interests as a parolee (challenging not the collection of the DNA sample, but the state’s continued retention and potential abuse of both his DNA information and sample), Wilson’s claim still falls squarely within the teaching of Samson. 4
2. Reasonableness Balancing
The totality-of-the-eircumstances test requires the court to determine the reasonableness of the subject search based on a balancing of the state’s interests against Wilson’s privacy interests. In
Conley,
the Sixth Circuit undertook this interest-balancing exercise in connection with a Fourth Amendment challenge to the federal DNA Act by a supervised releasee. The court characterized the government’s interests in establishing a nationwide DNA database as “compelling.”
Conley,
Wilson attempts to distinguish Conley by arguing that Ohio’s interests in enacting the Ohio DNA statute should be judged by its legislative history, not by the purposes served by the federal DNA Act. He argues the legislative history demonstrates that the collection of DNA samples from convicted felons in Ohio was authorized to promote the administration of criminal justice and aid in deterring, preventing and solving crimes. Obviously, these purposes are substantially similar to those identified in Conley. Wilson does not argue that these interests are not compelling, but maintains they are ordinary law enforcement objectives that do not qualify as “special needs.”
The argument is unavailing for two reasons. First, the governmental interests need not qualify as “special needs” under
*428
the totality-of-the-circumstances test, which, as indicated above, is properly applied in this case. Second, even courts that have applied the special-needs test have found that the very purposes identified both in
Conley
and in the cited legislative history аre not “ordinary,” but “special” law enforcement concerns that
do
qualify as special needs.
See e.g., Amerson,
Further,
Conley
is not materially distinguishable on the basis of the extent of intrusion, as the swabbing of saliva to obtain a DNA sample is even less invasive than the drawing of a blood sample.
Am-erson,
Unable to distinguish Conley, Wilson argues that it is wrongly decided. Yet, his arguments are the same arguments that have been consistently and conclusively rejected by the overwhelming weight of authority. Hence, even if we were free to depart from the precedent established in Conley, we have been presented no persuasive reason to do so. Because the Ohio DNA statute appears to be materially indistinguishable from the federal DNA Act and other similar state statutes that have been uniformly upheld by the federal courts against Fourth Amendment challenge, we find no error in the district court’s judgment in favor of the state defendants on Wilson’s Count I claim.
B. Substantive Due Process
In Count II, plaintiff alleges that the involuntary collection and retention of his DNA specimen and DNA information constitute a deprivatiоn of property and liberty without due process. The district court awarded judgment to the state defendants on this claim in part based on
Graham v. Connor,
Yet, the analysis of the substantive due process claim does not stop here. Wilson’s substantive due process claim is not based solely on the taking of his saliva, but also on the indefinite retention of his DNA sample and DNA information, as well as the sharing of his DNA profile through the state and national DNA-indexing systems. These actions, he alleges, constitute a deprivation of his liberty interest in nondisclosure of private information and are separately actionable as a substantive due process violation. Indeed, to the extent the сlaim is premised on the retention and disclosure of personal DNA information, it does not implicate the Fourth Amendment,
see Johnson v. Quander,
The district court also addressed this dimension of Wilson’s substantive due process claim, but only perfunctorily. It relied on
Padgett v. Donald,
Wilson insists that this privacy interest is a fundamental right, but acknowledges that the Sixth Circuit has rejected the notion. Whereas some other circuits have recognized the existence of a constitutional right of privacy in various types of confidential information,
see Denius v. Dunlap,
Wilson asks the court to expand the list of fundamental interests to include the confidentiality of his DNA profile, which he says contains a host of personal and medical information. He has failed to cite a single case, however, in which the disclosure of DNA profiles in DNA indexes has been held to abridge any right to privacy, much less a fundamental right entitled to the protection of substantive due process. Moreover, the state defendants maintain that the DNA profile disclosed in the Combined DNA Index System (“CODIS”) does not contain sensitive personal information, but is useful for human identity testing only. According to Dr. Julie A. Heinig, Assistant Laboratory Director of Forensic Services at the DNA Diagnostics Center in Fairfield, Ohio, no “personal information,” such as “race, criminal history or case-related informatiоn” is contained in CO-DIS.
On this record, it is clear that Wilson, a convicted felon, does not have a fundamental privacy interest in the information contained in his DNA profile that is protected by substantive due process. Where the state’s collection of the DNA specimen that produced the profile has been shown to be justified for Fourth Amendment purposes (considering (a) the compelling governmental interests in crime control, (b) the diminished privacy interest of a convicted felon, and (c) the minimal intrusion necessitated by collection of the specimen), the notion that principles of substantive due process would apply to frustrate the compelling governmental interests by prohibiting the disclosure of the DNA profile in CODIS is simply untenable.
Still, Wilson protests, contending that the state’s indefinite retention of his DNA sample, which, given advancements in scientific technology, may be “mined” in the future for a host of personal and medical information beyond that contained in his present DNA profile, cannot be justified. Indeed, Dr. Heinig recognized that blood or buccal samples contain genetic information that could conceivably be subject to misuse. She also observed, however, that the Act prescribes strict penalties for misuse of the samples or unauthorized disclosure of such information. These safeguards adequately ensure that any risk to Wilson’s legitimate privacy interests is minimized.
See Amerson,
*430
Further, Wilson’s concerns are purely speculative. The hypothetical possibility of some future abuse does not substantiate a justiciable controversy.
See Banks,
C. Procedural Due Process
In Count III, Wilson alleges that he was deprived of property and liberty without procedural due process when his DNA specimen was collected and his DNA profile disclosed in CODIS without a predeprivation hearing. The district court rejected the claim, observing that due process is a flexible concept and concluding that, since Wilson had diminished privacy interests as a prisoner, the degree of intrusion was minimal, and the risk of erroneous deprivation was slight, no pre-deprivation hearing was required. In support, the district court observed that the Sixth Circuit has already upheld the Ohio DNA statute against procedural due process challenge in an unpublished opinion,
Williams v. Dep’t of Rehabilitation and Correction,
Wilson quarrels in vain with the well-established notion that, as a prisoner, he had only extremely limited privacy interests. 6 He has also failed to identify what purpose would be served by a pre-deprivation hearing or other process. Further, while Wilson takes issue with the case law authorities relied on by the district court, he fails to demonstrate that they are wrongly decided and fails to identify a single decision by any court that recognizes a prisoner’s procedural due process right to a hearing before collection of a DNA sample or disclosure of a DNA profile in CODIS. Hence, Wilson’s objection *431 to the district court’s judgment in favor of the state defendants on Wilson’s Count III procedural due process claim is overruled.
D. Fifth Amendment Self-Incrimination
In Count IV of his complaint, Wilson alleges the state’s collection and retention of his DNA sample constitutes a violation of this Fifth Amendment privilege against self-incrimination. He maintains that DNA is testimonial because it could reveal personal information and therefore come within the ambit of the Fifth Amendment. The district court rejected the claim, citing numerous federal court decisions holding that DNA samples are not testimonial in nature. On appeal, Wilson has failed to identify a single contrary authority.
Most recently, the Ninth Circuit confirmed the unanimous view: “The extraction of DNA doesn’t implicate the privilege against self-incrimination because DNA samples are ‘physical’ evidence, not ‘testimonial’ еvidence.”
United States v. Zimmerman,
E. Disparate Impact
In Count V, Wilson alleges that the Ohio DNA statute has a disproportionate adverse impact on African-Americans because African-Americans make up a disproportionately large percentage of Ohio prison populations as compared to their representation in the general population. He argues that this disparate impact is actionable under 42 U.S.C. § 1983 in two ways: (1) as violative of Department of Justice regulations implementing § 602 of Title VI of the Civil Rights Act of 1964; and (2) as violative of Wilson’s constitutional right to equal protection of the laws.
1. DOJ Regulations Implementing Title VI
The district court correctly rejected the first theory, citing
Johnson v. City of Detroit,
Yet, while the dissenting opinion appears to have left open the possibility, the Court’s majority opinion did not: “[W]e have found no evidence anywhere in the text to suggest that Congress intended to create a private right to enforce regulations promulgated under § 602.”

*432
291,
2. Equal Protection
Wilson correctly argues that the district court’s ruling neglected to address his equal protection theory. This may be because Count V of his complaint does not expressly allege a violation of his equal protection rights; it relies exclusively on Title VI of the Civil Rights Act. Yet, even if we assumed Wilson properly stated a claim for denial of equal protection, it is apparent that the state defendants would have been entitled to summary judgmеnt.
Wilson acknowledges that the Ohio DNA Act is facially neutral. He also acknowledges that to prevail on his claim that the Act nonetheless violates equal protection, he must prove the existence of a racially discriminatory purpose behind the statute.
Washington v. Davis,
Washington
recognizes that evidence of disparate impact alone, though not irrelevant, is insufficient to justify an inference of invidious discriminatory purpose.
Id.
at 242,
Accordingly, Wilson having presented no evidence other than disparate impact to support his equal protection claim, summary judgment was properly awarded to the state defendants on this claim as well.
III. CONCLUSION
For the foregoing reasons, the district court’s judgment, awarding summary judgment in favor of the state defendants on all five of plaintiff Wilson’s challenges to the Ohio DNA statute, is AFFIRMED.
Notes
. During the pendency of this appeal, on June 17, 2007, Wilson was released from prison, subject to a three-year period of parole. As explained below, this change in status has no matеrial impact on the merits of his claims.
. The cases recognize a "privacy continuum,” in which an offender’s diminished privacy interests wax or wane, depending on his status in the criminal justice system. See
Banks,
. The district court, following Conley’s lead, evaluated the Ohio DNA statute under both tests.
. Even if we were to apply the more stringent special-needs test, there is no reason to believe the ultimate result would be different. It appears that every circuit that has applied the special-needs test has found the government’s interеst in DNA indexing to be a special need and has upheld the challenged statute.
See e.g., Conley,
. The Williams holding has been recently confirmed in
United States v. Bean,
. At the time Wilson's DNA sample was collected, the time before which he claims he ought to have been afforded a hearing, he was a prisoner, i.e., a person with very limited privacy rights. To the extent he now argues that his privacy rights are enhanced (i.e., now that he is a parolee) and soon may be fully restored (i.e., when he completes his term of parole supervision), he relies on circumstances that can hardly justify a retrospective requirement that he ought to have been afforded a pre-deprivation hearing.
