Deepfakes

Deepfakes
  • Context:

  • Addressing the special session on "AI for Democracy" at the India AI Impact Summit 2026, Lok Sabha Speaker Om Birla flagged deepfakes and misinformation as serious threats to democratic systems.

  • He emphasized that while Artificial Intelligence (AI) has the potential to make democracy more transparent and citizen-centric, it must be used to strengthen truth rather than distort facts.

  • About Deepfakes:

  • Deepfakes are artificially generated or manipulated media created using deep learning models to produce highly realistic but synthetic representations of people, objects, or events.

  • They are created using advanced Artificial Intelligence (AI) and machine-learning algorithms.

  • They utilize sophisticated algorithms to manipulate media, making it increasingly difficult to distinguish between reality and fabrication.

  • This capability is becoming a potent tool for digital impersonation and misinformation.

  • How Deepfakes Works:

  • Deepfakes involves in two models:

  • Discriminative models are used to tell the difference between things—for example, whether an image is real or fake.

  • Generative models, on the other hand, try to understand how real data works so they can create new, similar data.

  • The main difference is what they’re used for: discriminative models detect, and generative models create.

  • Generative adversarial networks:

  • GANs are a type of generative AI that trains a generative and a discriminative model together.

  • The relationship between both models is best described as friendly competition:

  • while the generator creates synthetic content, the discriminator works to distinguish real media from fakes.

  • This rivalry pushes the generator to improve its work until its outputs become nearly indistinguishable from authentic media.

  • Key Threats:

  • The Lok Sabha Speaker highlighted that deepfakes can manipulate public opinion, create confusion, and erode credibility in democratic institutions.

  • There is an urgent need to develop robust safeguards to protect democratic discourse.

  • Beyond domestic politics, deepfakes pose significant risks to international security.

  • In an era, rife with mistrust, they can convince populations of the veracity of false information, potentially leading to political tension, violence, or even war.

  • Countermeasures and Innovations:

  • Global Online Deepfake Detection System (GODDS):

  • To combat this menace, researchers have developed systems like GODDS.

  • Led by Professor Subrahmanian, this initiative provides a pro bono deepfake detection service specifically for journalists.

  • How it works:

  • It combines automated algorithms with human analysis (context and background knowledge) to render an expert opinion on whether a digital artifact is a deepfake.

  • Experts suggest a three-pronged approach to mediate the threat:

  • Implementing smart policies

  • Conducting public awareness campaigns

  • Deploying technical countermeasures.
