CONTROLLING PROCESSOR'S ACCESS TO INTERFACE DEVICE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240249265 titled 'CONTROLLING PROCESSOR'S ACCESS TO INTERFACE DEVICE
The abstract of the patent application describes a point of sale (POS) device that includes an output device, a secure enclosure housing a secure processor and tamper detection circuitry, and a switch controlled by the secure processor to share the output device between the secure processor and a main processor.
- The POS device includes an output device such as a speaker, display screen, or network interface.
- It houses a secure enclosure with a secure processor and tamper detection circuitry.
- A switch controlled by the secure processor shares the output device between the secure processor and a main processor.
- The secure processor can switch control of the output device from the main processor to itself.
- The secure processor can output an output dataset in various scenarios, including detecting tampering, recognizing suspicious behavior, or outputting sensitive information.
Potential Applications: - Retail environments - Banking institutions - Secure data transfer systems
Problems Solved: - Preventing tampering with the POS device - Ensuring secure output of sensitive information
Benefits: - Enhanced security measures - Protection of sensitive data - Improved trust in POS systems
Commercial Applications: Title: Secure Point of Sale Systems for Enhanced Data Protection This technology can be used in retail stores, banks, and other businesses that require secure transactions and data protection. It can help prevent fraud and unauthorized access to sensitive information.
Questions about the Technology: 1. How does the secure processor detect tampering with the secure enclosure? - The tamper detection circuitry within the secure enclosure is designed to detect any attempts to tamper with the device. 2. What measures are in place to ensure the secure processor can switch control of the output device effectively? - The switch controlled by the secure processor allows for seamless transition of control between the secure processor and the main processor.
Original Abstract Submitted
a point of sale (pos) device includes an output device such as a speaker, a display screen, or a network interface. the pos device also includes a secure enclosure housing a secure processor and tamper detection circuitry for detecting attempts to tamper with the secure enclosure. use of the output device is shared between the secure processor and a main processor via a switch that is controlled by the secure processor. the secure processor can switch control of the output device from the main processor to itself and can output an output dataset via the output device in a number of scenarios. these scenarios include the secure processor detecting an attempt to tamper with the secure enclosure, the secure processor recognizing that the main processor is behaving suspiciously, or the secure processor wanting to output sensitive information. the output dataset may include visual data, audio data, or network data.
