Apple’s Secure Enclave becomes the target of patent infringement lawsuits

Identity Security, a non-practicing entity, filed a lawsuit against Apple on Monday, claiming that the technology giant’s Secure Enclave technology infringes on four patents it owns and that the technology appears in almost all major product lines. The identity security company filed a lawsuit in the U.S. District Court for the Western District of Texas, which is always friendly to patent holders, against Apple’s “Secure Enclave” technology, which isolates sensitive user data in a dedicated subsystem To protect these data.

The system is integrated into Apple’s system chip design, and related technologies are currently deployed in iPhone, iPad, Apple Watch, Mac, Apple TV and HomePod. The identity security company claims that Apple’s implementation of Secure Enclave in its various hardware solutions infringes U.S. Patent Nos. 7,493,497, 8,020,008, 8,489,895, and 9,507,948, each of which details the creation of a unique microprocessor.

The digital identity on the device is a way to improve user security. The intellectual property also mentions password and biometric protection, as well as encryption and the possibility of integrating such solutions with digital payments.

The use cases listed for the intellectual property owned by the identity security company include the secure storage and communication of the user’s name, digital photo, address, date of birth, social security number, driver’s license number, digital photo, biometric information, credit card information, bank account information, The name of the company, the date and place of establishment of the company, the names of company managers, the names of company partners, and database administrators. The patent claims section details the company’s implementation, not necessarily consumers.

All four patents listed Aureliano Tan, Jr. as their inventor, and were initially assigned to Integrated Information Solutions in an application dating back to 2000. Apple’s Secure Enclave debuted on the iPhone 5S in 2013 as a way to securely store user fingerprint data. That year, Apple also launched the first biometric authentication device-Touch ID.

As Apple later detailed in a technical white paper, Secure Enclave is a coprocessor built into the company’s SoC design. This component has its own startup sequence and software update mechanism and is responsible for “all encryption operations of data protection key management, even if the kernel is damaged, it can still maintain the integrity of data protection.”

Starting from the A11 and S4 processors, Secure Enclave now includes a “memory protected engine and encrypted memory with anti-replay function, secure boot, a dedicated random number generator, and its own AES engine”, according to Apple Weighed. Its processor runs a customized version of the L4 microkernel.

The four patents owned by Identity Security have no application in the real world, and the technology has never been authorized. The lawsuit requires compensation for losses, payment of litigation costs, and continuous payment of royalties.
