GuardianAI: Social Scam Protector
AI-Powered Defense Against Social Engineering Scams
In 2022, Americans lost over $8.8 billion to fraud, with imposter scams and investment fraud leading the categories. Phone calls remain the most common contact method for scammers, followed closely by text messages and emails.
The Growing Threat of Social Engineering
Social engineering attacks exploit human psychology rather than technical vulnerabilities. These sophisticated scams have devastating financial and emotional consequences, particularly for vulnerable populations:
- Elderly individuals: Adults over 60 report median losses of $1,500 per scam incident, three times higher than younger age groups
- Teenagers and young adults: Particularly susceptible to romance scams and get-rich-quick schemes
- Non-native English speakers: Often targeted due to potential unfamiliarity with official processes
- Socially isolated individuals: More vulnerable due to limited external validation sources
Beyond financial losses, victims experience significant emotional trauma, including damaged self-confidence, depression, anxiety, strained family relationships, and reluctance to use technology following victimization.
Introducing GuardianAI
GuardianAI represents a revolutionary approach to scam prevention by providing real-time intervention during potential scam attempts rather than education alone. This AI-powered mobile defense system continuously monitors communications for signs of social engineering, protecting users across multiple threat vectors.

Advanced Call Protection Strategies
The GuardianAI system offers layered protection that adapts to user preferences and evolving threat levels during calls:
Progressive Intervention
Unlike traditional call screening that only works at the beginning of a call, GuardianAI provides continuous monitoring with escalating protection options:
- Pre-call Assessment: Initial risk scoring of incoming numbers
- Continuous Monitoring: Real-time analysis of all calls, even those from trusted numbers
- Dynamic Alerts: Warning cards that appear when suspicious patterns emerge during any conversation
- Escalating Options: Protection choices that adapt to the detected threat level
Mid-Call Handoff Technology
A key innovation in GuardianAI is the ability to seamlessly transfer an active call to AI when warning signs appear:
- User receives a discreet alert when suspicious keywords or patterns are detected
- Alert presents options: continue with guidance, end call, or transfer to GuardianAI
- If GuardianAI handoff is selected, the system creates a smooth transition using voice synthesis
- Call automatically switches to speaker mode so user can hear both sides of the conversation
- User's microphone is muted to prevent accidental interruptions
- Real-time transcript appears on screen showing the ongoing conversation
- Recording begins automatically for evidence collection
- User retains control options including:
- Take back control of the call at any time
- End call immediately
- Add notes or flags to the recording
- Send live alert to designated guardians

Real-World Impact: Case Studies
Protecting the Elderly
Maria, 78, received a call that appeared to be from her local bank branch. Without initial warnings, she answered normally. During the conversation, the caller began asking for her account information and mentioned that there was "suspicious activity" that needed to be addressed immediately. GuardianAI's continuous monitoring detected these scam indicators and displayed warning cards with options to hang up or transfer to GuardianAI.
Feeling uncomfortable but unsure how to end the call politely, Maria tapped the "Let GuardianAI Take Over" option. The system seamlessly took control of the conversation using a voice synthesized to match Maria's speech patterns. The call automatically switched to speaker mode with Maria's microphone muted, allowing her to listen to the exchange. GuardianAI continued the interaction to gather evidence while Maria watched the real-time transcript on her screen.
If desired, she could have tapped "Take Over" to rejoin the conversation, but she chose to let the AI continue. The system confirmed it was a scam attempt and recorded the entire exchange. This evidence was later shared with Maria's daughter and the local authorities. Maria appreciated being able to start the call herself but having backup protection when warning signs appeared.
Safeguarding Young Adults
Tyler, 19, was targeted by a cryptocurrency investment scam promising extraordinary returns. When clicking on a suspicious link, GuardianAI identified the communication pattern and provided contextual information about similar investment scams. GuardianAI analyzed the investment website in real-time, highlighting red flags such as unrealistic returns and pressure tactics. It then suggested specific questions Tyler should ask to verify legitimacy.
Following GuardianAI's guidance, Tyler asked challenging questions that the scammer couldn't answer convincingly. Tyler avoided a potential $3,000 loss and shared the scam details for community protection.
Supporting Vulnerable Communities
The Lee family, recent immigrants with limited English proficiency, received official-looking messages claiming issues with their immigration status. GuardianAI's multilingual support identified the text messages as fraudulent and provided guidance in their native language. When they received a follow-up SMS with an urgent link claiming to be from "USCIS," the system automatically detected the URL as fraudulent and displayed a warning explaining that government agencies don't request personal information via text links.
GuardianAI translated official USCIS contact information into their native language so they could verify the communicationindependently.
