That redesign would raise costs by 8 to 12 percent and delay production by six to nine months. Companies only make such changes when laws or lawsuits force them. For example, after the 2014 iCloud photo leaks and the 2018 GDPR rules, cloud encryption became standard. But phone makers did not isolate sensors from the main chip. The situation will only change when a major data breach shows that hackers stole data directly from shared sensor pathways. Then liability will shift from cloud storage to hardware design. New rules or insurance demands will break the cost-saving logic. Until that happens, not using secure enclaves is a rational choice for manufacturers. After it, that same choice becomes impossible." }, { "source": 64, "target": 109, "relationship": "__anchor__" }, { "source": 64, "target": 111, "relationship": "__anchor__" }, { "source": 64, "target": 113, "relationship": "__anchor__" }, { "source": 64, "target": 115, "relationship": "__anchor__" }, { "source": 64, "target": 117, "relationship": "__anchor__" }, { "source": 64, "target": 119, "relationship": "__anchor__" }, { "source": 111, "target": 121, "relationship": "__anchor__" }, { "source": 121, "target": 122, "relationship": "**A corrupt initial enrollment undermines national identity systems because all later security depends on a single, unchangeable registration step.**\n\nNational identity systems that permanently link biometric data to a unique ID rely entirely on the accuracy of the first registration step. This starting moment is the system's weakest point. Once a person’s biographic and biometric details are locked to a permanent ID, all later security depends on that initial step. Even temporary verification tokens depend on the same fixed database anchor. If the enrollment process is hacked, faked, or corrupted, that false identity spreads into every linked service. This includes critical systems like digital payments. Even strong encryption or secure data storage cannot fix the risk if the original identity record is wrong. The reason is simple: no one can change or re-verify the original binding. Fraud from a single corrupt entry can spread system-wide.

Google and Apple set technical standards that shape how devices handle fingerprints and facial recognition. Google enforces its standards through certification for Android devices. Apple tightly controls both hardware and software in its phones. The EU’s privacy law does not require specific security designs. Device makers are free to choose how they implement protections. Many mid-priced and low-cost Android phones outside the US and Europe lack strong hardware safeguards. This is due to fragmented chip supply chains. Companies like MediaTek or Unisoc often skip dedicated security cores or offer weaker ones. Apple phones protect biometric data by default. Google’s stricter rules apply only to certain certified devices. Most budget Android phones in developing markets process biometrics using software protection.

This saved about thirty to fifty cents per phone. For a company selling 100 million phones, that means savings of $30 to $50 million per model. Apple added secure hardware for fingerprints in 2013 but waited until 2018 to protect other sensor data. This delay shows even careful firms act only when theft risks are clear and direct. Security is added only when it supports a visible feature like Face ID. Protection is not given to all sensors by default.

Most phones last five to seven years. This leaves a gap of two to four years without security updates. The US Government Accountability Office documented this in a 2021 report. During this gap, biometric data may no longer be secure. Protection depends on the trusted hardware environment. This environment must stay updated to guard against new hacking methods. Examples include speculative execution flaws or memory bugs in sensor systems. Encryption alone cannot prevent re-authentication attacks if the hardware keys are compromised. Once updates stop, the system can no longer defend against these threats. Strong initial encryption becomes ineffective. Security degrades even if the device still works.

These companies include device makers, operating system providers, and mobile carriers. Each must agree before an update can be released. This slows down the process significantly. Even when fixes are ready, they cannot deploy without coordination. The FCC reported this issue in 2020. Most Android phones are affected. Delays weaken the phone's built-in security over time. The problem is not that companies stop caring. It is that they face more pressure to launch new devices quickly than to maintain old ones. Without federal rules requiring updates for a minimum time, companies lack motivation to keep supporting older models. As a result, user security suffers by default.

Apple and Samsung use on-device processing with strong software protections. These systems rely on regular updates, even after official support ends. Hardware design alone does not guarantee security. Instead, ongoing software updates are key. Standards from NIST and ISO show that protected biometric templates are safer than raw data. Google’s Pixel phones show long-term security is possible. Lasting protection depends on continued software maintenance. This is driven by rules and market forces.
