💻 Quick Technical Summary
The new solution relies on leveraging the capabilities of artificial intelligence and OCR technologies to inspect incoming phone numbers in real time while the phone call is in progress. The user activates a Shortcut on an iOS device that captures the screen, extracts the phone number using Embedded OCR, and then sends the number to ChatGPT to check it against known databases for fraud prevention and nuisance calls. The results appear before the caller ends the call, enabling the user to make the appropriate decision, whether to answer or ignore. This integration between artificial intelligence, embedded computing, and the automation feature in smartphone operating systems represents a modern direction in improving Hardware security and the user experience level.
⚙️ How Does the System Verify Numbers While Ringing?
In modern computer engineering and smartphone systems, many technologies overlap to provide advanced features despite resource constraints. This system relies on combining several important components and technologies within the framework of automation in the iOS system:
- Automatic screen capture (Take Screenshot) when a Shortcut is invoked, capturing an instant image of what appears on the call screen.
- Text extraction from an image (OCR) technology that enables reading numbers from the screen image and extracting them as text that can be processed.
- Integration with ChatGPT to perform a quick online search for the phone number within databases or public sources of violating numbers.
- Show Alert displays the result in the user interface to inform the user whether the number is safe or fraudulent.
This chain of operations works sequentially and with high efficiency, benefiting from the evolution of Embedded Systems and embedded AI capabilities.
🧠 The Role of AI on Hardware in Improving Security
Artificial intelligence (AI) has created a revolution in high-performance computing systems, but it has also become an integral part of embedded systems on mobile devices.
In this case, the verification process relies on using advanced AI models to understand text and perform an independent smart search, relying on the power of the CPU and GPU inside the phone.
- Smart routing of incoming call data.
- Analyzing number patterns as fraudulent or safe.
- Sorting incoming calls quickly using the phone’s cloud resources and background tasks.
This application highlights key trends in modern SoC design, where AI Accelerators are integrated to speed up text processing and data analysis in real time, improving the user experience and enhancing hardware security.
📡 Integrated Technologies and Modern Trends
What we observe in this small project is a practical application of several fundamental trends in computer engineering:
- Automation with AI: relying on smart automation in mobile devices to detect security threats automatically.
- Smart embedded systems: leveraging computing capabilities within embedded systems equipped with advanced processing cores and AI accelerators.
- Hardware Security: providing an additional security layer based on real-time data analysis at the device level rather than only through software.
- User interaction with smart devices: using intuitive control methods such as triple tapping the back of the phone to run complex tasks.
These trends are proof of the rapid evolution of computer engineering and its move toward combining AI capabilities with improved hardware performance, reducing reliance on the cloud network alone.
🔌 How the Shortcut Is Built and the Complexities of Implementation
Despite the simplicity of using the Shortcut, its engineering background depends on multiple complex fields in computer engineering:
- OCR Embedded Systems: the interaction between the phone camera system and the software to extract numbers accurately from images in real time.
- Advanced API integration: the Shortcut communicates with ChatGPT APIs to analyze the acquired data.
- Task management and synchronization: handling the four steps, from capturing the image to showing the result, within the time limit of a short phone call.
- Control and accessibility settings: customizing a physical control such as triple tap on the back of the phone to trigger the action, which is an example of integrating mechanical and software systems.
Developing such a system shows how modern computer engineering can combine different technologies to provide advanced security solutions without affecting the user experience.
🛡️ System Limits and Existing Security Challenges
Despite the clear technical advantages, it should be noted that the system is not error-free:
- Dependence on updating databases that rely on user reports, which means there is a possibility of fraudulent numbers that have not yet been recorded.
- The complexity of balancing performance between response speed and intelligent processing performance to maintain system speed during the call.
- Possible errors in optical character recognition (OCR) due to different screen backgrounds or unclear numbers.
- Dependence on the availability of a stable and reliable internet connection to perform an AI search through ChatGPT.
Therefore, these systems are considered one of multiple security layers, not the absolute final solution in the field of protecting phones from fraudulent calls.
📱 The Future Direction of Call Systems and AI
With the evolution of modern SoC devices and the advancement of artificial intelligence, computer engineers are working to enable end-user devices to perform complex intelligent tasks in real time.
Although the iOS Shortcut example illustrates the current practical method, the direction includes:
- Developing embedded AI Accelerators within the hardware system to increase the speed of threat processing.
- Using Embedded Systems with broader analytical capabilities and greater complexity in devices such as phones and IoT.
- Adopting Edge Computing methods to process data locally to reduce reliance on the network and protect privacy.
- Integrating hardware security systems with call-signing and End-to-End encryption technologies to reduce fraud effectively.
🌐 Alternatives and Complementary Technologies on Other Systems
Although iOS technologies are advanced, the Android system also offers available tools for verifying and screening calls:
- Using built-in Call Screening tools that route the call through AI systems to verify the caller.
- Using automation apps such as Tasker with add-ons that support invoking standard AI services to create similar scenarios.
- Devices that allow hardware compatibility with advanced security systems such as Hardware-Level Caller ID verification.
These technologies continue to provide advanced benefits in different computing environments within an integrated relationship between hardware and software.
⚡ Conclusion
The evolution of using artificial intelligence at the hardware and embedded-systems level has made it possible for individuals to have smart systems for screening call numbers in real time. Combining technologies such as OCR with cloud services provides greater security and control over the communication experience, especially amid the rising risks of fraudulent calls. Despite the innovation, the challenge remains in improving system accuracy and expanding it across different platforms.
Applications such as smart Shortcuts on iOS represent an inspiring model of how modern computer engineering can be adapted to serve users more safely and intelligently.
