🤓 Expert Deep Dive
Technically, this term bridges two worlds. In the 'IMA' (Integrity Measurement Architecture) world, it involves hashing file contents and storing those hashes in a 'Trusted Platform Module' (TPM). In the 'Block Vignetting' world, it involves analyzing the 'Luminance Gradient' across serialized blocks of a physical document. Modern AI-driven eKYC systems combine these: they verify the hardware-backed identity of the device (IMA) and then verify the optical integrity of the document (Block Vignetting) to determine if a 'Presentation Attack' is occurring. If the device is rooted (IMA fails) or the card vignetting is artificial (Optical fails), the transaction is blocked.
