Possible Risks of online Age Verification

EFF recently listed 10 dangers of Age Verification.  Governments and corporations increasingly mandate users to undergo types of age verification. Online age verification can protect children from some harms, but it also introduces significant risks around privacy, security, surveillance, discrimination, and free expression.scientificamerican+1

Here are the major risk points: 

​

Privacy and data security

Most robust age checks require uploading IDs, payment data, or biometric scans, creating large databases of highly sensitive information linked to browsing behavior. These databases become attractive targets for hacking, leaks, extortion, and secondary uses such as data brokering, with past breaches showing that even services promising deletion sometimes retain and expose documents and messages.abcnews.go+3​

Surveillance and loss of anonymity

Because age verification typically ties a real-world identity (or biometric template) to online activity, it can enable tracking of what sites people visit, when, and from where. This undermines anonymity that is important for journalism, activism, and sensitive information‑seeking, and can be repurposed for censorship, political profiling, or other forms of state and corporate surveillance.reddit+3​

Chilling effects and exclusion

Knowing that accessing certain content requires face scans or ID uploads can deter adults and minors from legitimate uses, including health, sexuality education, or political material, producing a strong chilling effect on lawful speech and information‑seeking. People without formal IDs, or in marginalized groups, may be effectively excluded from platforms that make age verification a condition of access, deepening existing digital divides.edri+2​

Biometric and algorithmic risks

Biometric age estimation (via facial analysis, voice, or behavior) processes highly sensitive data that cannot be revoked if compromised and can be repurposed for identification. These systems are often less accurate for women, people of color, and certain age ranges, leading to systematic misclassification, extra scrutiny, and potential discrimination, especially against already marginalized communities.biometricupdate+3​

False sense of safety and mission creep

Age checks are relatively easy for determined minors to circumvent (e.g., fake or borrowed IDs, VPNs), so heavy reliance on them can create a false sense of security while pushing harms into less regulated spaces. Once age‑linked identity infrastructure exists, there is a strong risk of “mission creep,” where tools introduced for child safety are extended to broader content control, behavioral profiling, or other non‑child‑protection purposes.privacyguides+3
