An Overview of Face Morphing: Evolution, Working & Mitigation

Technological innovation has taken the world by storm, offering great benefits to people and simplifying access to services or privileges. Taking advantage of this innovation, malicious actors with unethical intentions deploy sophisticated tactics to fulfill their nefarious activities. Face morphing which was initially developed for offering applications in arts and media is now being used by cyber fraudsters for malicious purposes. Using face morphing attacks, cybercriminals effortlessly dodge authentication systems and get unauthorized access to services or privileges. The negative use cases of online face morphing have outweighed the positive applications, stressing the need to develop robust strategies to mitigate the potential threats.  

Quick Insights into Online Face Morphing 

Face morphing is a sophisticated digital manipulation technology that blends facial images of selected individuals to create a convincing and highly realistic identity. Deepfakes, synthetic media often use online face morphing to generate sharp outputs, blurring the boundary between real and fake identities. This blending technique combines images or videos of the victims to generate a whole new identity, showing a resemblance with the input data. 

The fabricated media appears supernatural and convincing, even the advanced authentication system fails to flag the synthetic identities. Face morph presents positive and negative applications, however, negative use cases are leading as cybercriminals use digital manipulation technology for self-interests. Positive examples include advertisements, entertainment, medical research, or creating visual effects, while negative use cases include identity fraud, deepfakes, or identity spoofing. 

Evolution and the Working Behind 

Talking about the early days when face morphing was used to create synthetic, it was a time-consuming process and artists used to integrate techniques like frame-by-frame animation or double exposure to introduce smooth transitions between faces. Technology innovation has made the process simplified and advanced software tools & sophisticated algorithms are employed to generate sharp outputs. 

Online face morphing works in a series of steps to create satisfying results making it challenging to discern between real and fake. Initially, a large volume of facial data of the targeted individuals is collected and required facial features are precisely extracted. Depending upon the resemblance between facial features, they are slowly cross-dissolved on the selected images or videos. By making use of deep learning, the facial features are perfectly blended into each other, and highly realistic identities are constructed. 

Mitigating the Potential Threats 

The alarming threats associated with face morphing attacks, stress authentication solutions to develop advanced technologies to mitigate the potential risks. To ensure the integrity of digital personas and safeguard confidential information from exploitation, sophisticated techniques must be there in place to stay ahead of the curve. 

  • Advanced technologies like convolutional neural networks (CNN) and generative adversarial networks (GANs) are employed to substantially detect face morph. These deep learning techniques are trained on a large volume of identities and fraudulent attempts, enabling them to detect anomalies or inconsistencies in real-time. Integrating these sophisticated tools, biometric authentication systems can effortlessly detect fabricated identities. 

  • By deploying cloud-based AI services, the potential risks of online face morphing are significantly reduced, as it allows the timely detection of fabricated identities. The detection is conducted in real-time, restricting cyber fraudsters from entering the services or privileges which significantly safeguards digital identities from being exploited. 

  • Integrating texture analysis and landmark detection, biometric authentication systems can minutely analyze the credibility of the claimed identity. Humans have natural skin texture and there are subtle variations in the skin tone, while facial morph presents smooth skin texture, indicating the presence of spoofed identities. Moreover, by efficiently analyzing facial landmarks or detecting unnatural variations, real persons can be seamlessly distinguished from fake identities. 

Multi-Modal Biometrics 

The rising threats of online face morphing are harming the integrity of digital personas and affecting the victims badly. To effectively curb the growing concerns, a multi-faceted approach is required. Combining multiple biometric identifiers can enhance the security of digital identities, making it arduous for cyber fraudsters to steal your confidential information. By chance, cybercriminals steal or replicate your fingerprints, they won’t be able to pass facial recognition or voice recognition part, restricting access to services or systems. 

Compliance with Regulatory Frameworks 

With effective compliance with the regulatory framework and the development of transparent privacy policies, the integrity of confidential information can be preserved. If biometric authentication solutions follow the regulatory guidelines and conduct regular audits, the potential loopholes in the biometric verification systems can be detected and addressed significantly. Furthermore, this compliance helps businesses and authentication solutions to effortlessly curb the distressing threats of online face morphing. 

Final Word 

Raising awareness about facial morph and associated threats at individual, organizational, and governmental levels can play a critical role in staying ahead of this evil. Individuals are suggested to stay vigilant and reduce their digital footprint to evade the trap of identity theft. Businesses must implement robust prevention and detection measures to create a safe online community. Governments can devise stringent regulations and guidelines mandating the appropriate use of technologies and devising severe penalties for potential misuse.
