Apple had 29 patents in regtech during Q4 2023. Apple Inc’s patents filed in Q4 2023 focus on managing SIM data for wireless devices through secure encryption and storage techniques, as well as enhancing privacy through PE beacon frames. The SIM data is encrypted using an encryption key, with a portion stored in a secure element and the rest in external memory. The PE beacon frames include random identifiers and checksum IDs to identify affiliated access points, allowing for early termination of reception based on sequence numbers.

Application: Secure storage and processing of sim data (Patent ID: US20230362631A1)
The patent application by Apple Inc. describes a method and system for managing subscriber identity module (SIM) data on a wireless device. The technique involves encrypting select SIM data using an encryption key by a processor external to a secure element, such as a universal integrated circuit card (UICC) or electronic UICC (eUICC), and storing parts of the encrypted data in the secure element and non-volatile memory (NVM) of the device. The encryption key is securely stored in the NVM, and both the encrypted SIM data and encryption key are required for decryption and recovery of the SIM data.
The method outlined in the patent involves obtaining unencrypted sensitive user data, encrypting it with a symmetric key security algorithm, dividing it into parts, and storing them in the secure element and NVM of the wireless device. The wireless device is further configured to retrieve and decrypt the encrypted data when required for communication with a cellular wireless network. The patent also details the use of advanced encryption standard (AES) algorithm, storage of symmetric key in a secure NVM, and the inclusion of various types of sensitive user data like location information and non-access stratum count value. Additionally, the patent describes a wireless device with processing circuitry that executes instructions to secure and manage SIM data following the outlined method.
