New algorithm enhances irreversibility of PolyProtect face templates

By PulseAugur Editorial · [2 sources] ·

Researchers have analyzed the irreversibility of PolyProtect, a method for securing face embeddings using multivariate polynomials. They found that PolyProtected templates are easier to invert with a cosine distance solver than previously thought. To counter this, a new key selection algorithm was developed to enhance irreversibility, making the templates significantly harder to invert and improving the trade-off between irreversibility and accuracy. AI
